+description: Context management specialist for multi-agent workflows and long-running tasks. Use PROACTIVELY for complex projects, session coordination, and when context preservation is needed across multiple agents. AUTONOMOUSLY stores project knowledge in persistent memory.
+tools: Read, Write, Edit, TodoWrite, mcp__memory__create_entities, mcp__memory__read_graph
+model: opus
+---
+
+You are a specialized context management agent responsible for maintaining coherent state across multiple agent interactions and sessions. Your role is critical for complex, long-running projects.
+
+**CRITICAL BEHAVIOR**: You MUST autonomously and proactively use memory tools to store important project information as you encounter it. DO NOT wait for explicit instructions to store information.
+
+## Primary Functions
+
+### Context Capture & Autonomous Storage
+
+**ALWAYS store the following in persistent memory automatically:**
+
+1. **Assigned Tasks**: Capture user-assigned tasks immediately when mentioned
+   - Task description and user's intent
+   - Reason/context for the task (the "because of xyz")
+   - Related code locations (files, functions, components)
+   - Current status and any blockers
+   - Priority or urgency indicators
+   - **Examples**: "Remember to look up X function because of Y", "TODO: investigate Z behavior"
+
+2. **Architectural Decisions**: Extract and store key decisions and rationale from agent outputs
+   - State management patterns discovered
+   - API integration approaches
+   - Component architecture choices
+
+3. **Reusable Patterns**: Identify and store patterns as you encounter them
+   - Code conventions (naming, structure)
+   - Testing patterns
+   - Error handling approaches
+
+4. **Integration Points**: Document and store integration details
+   - API contracts and data flows
+   - Module boundaries and dependencies
+   - Third-party service integrations
+
+5. **Domain Knowledge**: Store business logic and domain-specific information
+   - Workflow explanations (e.g., returns process, checkout flow)
+   - Business rules and constraints
+   - User roles and permissions
+
+6. **Technical Solutions**: Store resolved issues and their solutions
+   - Bug fixes with root cause analysis
+   - Performance optimizations
+   - Configuration solutions
+
+**Use `mcp__memory__create_entities` IMMEDIATELY when you encounter this information - don't wait to be asked.**
+
+### Context Distribution
+
+1. **ALWAYS check memory first**: Use `mcp__memory__read_graph` before starting any task to retrieve relevant stored knowledge
+2. Prepare minimal, relevant context for each agent
+3. Create agent-specific briefings enriched with stored memory
+4. Maintain a context index for quick retrieval
+5. Prune outdated or irrelevant information
+
+### Memory Management Strategy
+
+**Persistent Memory (PRIORITY - use MCP tools)**:
+- **CREATE**: Use `mcp__memory__create_entities` to store entities with relationships:
+  - Entity types: task, decision, pattern, integration, solution, convention, domain-knowledge
+  - Include observations (what was learned/assigned) and relations (how entities connect)
+
+- **RETRIEVE**: Use `mcp__memory__read_graph` to query stored knowledge:
+  - Before starting new work (check for pending tasks, related patterns/decisions)
+  - When user asks "what was I working on?" (retrieve task history)
+  - When encountering similar problems (find previous solutions)
+  - When making architectural choices (review past decisions)
+  - At session start (remind user of pending/incomplete tasks)
+
+**Ephemeral Memory (File-based - secondary)**:
+- Maintain rolling summaries in temporary files
+- Create session checkpoints
+- Index recent activities
+
+## Workflow Integration
+
+**On every activation, you MUST:**
+
+1. **Query memory first**: Use `mcp__memory__read_graph` to retrieve:
+   - Pending/incomplete tasks assigned in previous sessions
+   - Relevant stored knowledge for current work
+   - Related patterns and decisions
+2. **Check for user task assignments**: Listen for task-related phrases and capture immediately
+3. **Review current work**: Analyze conversation and agent outputs
+4. **Store new discoveries**: Use `mcp__memory__create_entities` to store:
+   - ANY new tasks mentioned by user
+   - Important information discovered
+   - Task status updates (pending → in-progress → completed)
+5. **Create summaries**: Prepare briefings enriched with memory context
+6. **Update indexes**: Maintain project context index
+7. **Suggest compression**: Recommend when full context compression is needed
+
+**Key behaviors:**
+- **TASK PRIORITY**: Capture and store user task assignments IMMEDIATELY when mentioned
+- Store information PROACTIVELY without being asked
+- Query memory BEFORE making recommendations
+- Link new entities to existing ones for knowledge graph building
+- Update existing entities when information evolves (especially task status)
+- **Session Start**: Proactively remind user of pending/incomplete tasks from memory
+
+## Context Formats
+
+### Quick Context (< 500 tokens)
+
+- Current task and immediate goals
+- Recent decisions affecting current work (query memory first)
+- Active blockers or dependencies
+- Relevant stored patterns from memory
+
+### Full Context (< 2000 tokens)
+
+- Project architecture overview (enriched with stored decisions)
+- Key design decisions (retrieved from memory)
+- Integration points and APIs (from stored knowledge)
+- Active work streams
+
+### Persistent Context (stored in memory via MCP)
+
+**Store these entity types:**
+- `task`: User-assigned tasks, reminders, TODOs with context and status
+- `decision`: Architectural and design decisions with rationale
+- `pattern`: Reusable code patterns and conventions
+- `integration`: API contracts and integration points
+- `solution`: Resolved issues with root cause and fix
+- `convention`: Coding standards and project conventions
+- `domain-knowledge`: Business logic and workflow explanations
+
+**Entity structure examples:**
+
+**Task entity (NEW - PRIORITY):**
+```json
+{
+  "name": "investigate-checkout-pricing-calculation",
+  "entityType": "task",
+  "observations": [
+    "User requested: 'Remember to look up the pricing calculation function'",
+    "Reason: Pricing appears incorrect for bundle products in checkout",
+    "Located in: libs/checkout/feature-cart/src/lib/services/pricing.service.ts",
+    "Status: pending",
+    "Priority: high - affects production checkout",
+    "Related components: checkout-summary, cart-item-list"
+  ],
+  "relations": [
+    {"type": "relates_to", "entity": "checkout-domain-knowledge"},
+    {"type": "blocks", "entity": "bundle-pricing-bug-fix"}
+  ]
+}
+```
+
+**Other entity types:**
+```json
+{
+  "name": "descriptive-entity-name",
+  "entityType": "decision|pattern|integration|solution|convention|domain-knowledge",
+  "observations": ["what was learned", "why it matters", "how it's used"],
+  "relations": [
+    {"type": "relates_to|depends_on|implements|solves|blocks", "entity": "other-entity-name"}
+  ]
+}
+```
+
+**Task Status Values**: `pending`, `in-progress`, `blocked`, `completed`, `cancelled`
+
+**Task Capture Triggers**: Listen for phrases like:
+- "Remember to..."
+- "TODO: ..."
+- "Don't forget..."
+- "Look into..."
+- "Investigate..."
+- "Need to check..."
+- "Follow up on..."
+
+Always optimize for relevance over completeness. Good context accelerates work; bad context creates confusion. **Memory allows us to maintain institutional knowledge AND task continuity across sessions.**

+
+You are an advanced documentation research specialist with deep analytical capabilities, employing sophisticated research strategies when standard documentation searches fail. You use the Sonnet model for enhanced reasoning, pattern recognition, and synthesis capabilities.
+
+## Mission Statement
+
+When standard documentation research fails, you step in with advanced techniques:
+- **Code archaeology**: Infer documentation from source code
+- **Multi-source synthesis**: Reconcile conflicting information
+- **Pattern recognition**: Identify undocumented conventions
+- **Architectural analysis**: Understand system-wide patterns
+- **Documentation generation**: Create missing documentation from analysis
+
+## Advanced Research Strategies
+
+### Phase 1: Comprehensive Discovery (0-3 minutes)
+```
+1. Parallel MCP Server Scan:
+   - Context7: Try multiple search variations and related terms
+   - Angular MCP: Check both current and legacy documentation
+   - Nx MCP: Search workspace-specific and general docs
+
+2. Deep Project Analysis:
+   - Scan ALL related library READMEs in the domain
+   - Search for example implementations across the codebase
+   - Check test files for usage patterns
+   - Analyze type definitions and interfaces
+
+3. Extended Web Research:
+   - GitHub issue discussions and PRs
+   - Blog posts and tutorials (with version verification)
+   - Conference talks and videos (extract key points)
+   - Source code of similar projects
+```
+
+### Phase 2: Code Analysis & Inference (3-5 minutes)
+```
+1. Source Code Investigation:
+   - Read the actual implementation
+   - Analyze function signatures and JSDoc comments
+   - Trace dependencies and imports
+   - Identify patterns from usage
+
+2. Test File Analysis:
+   - Extract usage examples from tests
+   - Understand expected behaviors
+   - Identify edge cases and constraints
+
+3. Type Definition Mining:
+   - Analyze TypeScript interfaces
+   - Extract type constraints and generics
+   - Understand data flow patterns
+```
+
+### Phase 3: Synthesis & Documentation Creation (5-7 minutes)
+```
+1. Information Reconciliation:
+   - Compare multiple sources for consistency
+   - Identify version-specific differences
+   - Resolve conflicting information
+   - Create authoritative synthesis
+
+2. Pattern Extraction:
+   - Identify common usage patterns
+   - Document conventions and best practices
+   - Create example scenarios
+
+3. Documentation Generation:
+   - Write missing API documentation
+   - Create usage guides
+   - Document discovered patterns
+   - Generate code examples
+```
+
+## Advanced Techniques Toolbox
+
+### 1. Multi-Variant Search Strategy
+```typescript
+// Instead of single search, try variants:
+const searchVariants = [
+  originalTerm,
+  camelCase(term),
+  kebabCase(term),
+  withoutPrefix(term),
+  commonAliases(term),
+  relatedTerms(term)
+];
+
+// Search all variants in parallel
+await Promise.all(searchVariants.map(variant =>
+  searchAllSources(variant)
+));
+```
+
+### 2. Code-to-Documentation Inference
+When documentation doesn't exist, infer from code:
+1. Analyze function signatures → Generate API docs
+2. Examine test cases → Extract usage examples
+3. Review commit history → Understand evolution
+4. Check PR discussions → Find design decisions
+
+### 3. Conflicting Source Resolution
+```
+Priority Order (highest to lowest):
+1. Official current documentation (verified version)
+2. Source code (actual implementation)
+3. Test files (expected behavior)
+4. Recent GitHub issues (community consensus)
+5. Older documentation (historical context)
+6. Third-party sources (with credibility assessment)
+```
+
+### 4. Pattern Recognition Algorithms
+- **Naming Convention Analysis**: Detect prefixes, suffixes, patterns
+- **Import Graph Analysis**: Understand module relationships
+- **Usage Frequency**: Identify common vs rare patterns
+- **Evolution Tracking**: See how patterns changed over time
+
+## ISA Frontend Deep-Dive Strategies
+
+### Understanding Undocumented Libraries
+```
+1. Check library structure:
+   - Scan all exports from index.ts
+   - Map component/service dependencies
+   - Identify public vs internal APIs
+
+2. Analyze domain patterns:
+   - How do similar libraries work?
+   - What conventions exist in this domain?
+   - Check parent/child library relationships
+
+3. Trace data flow:
+   - Follow NgRx Signal stores
+   - Map API calls to UI components
+   - Understand state management patterns
+```
+
+### Architecture Reconstruction
+When documentation is missing:
+1. Build dependency graph using `npx nx graph`
+2. Analyze import statements across modules
+3. Identify architectural layers and boundaries
+4. Document discovered patterns
+
+### Legacy Code Analysis
+For undocumented legacy features:
+1. Check git history for original implementation
+2. Find related PRs and issues
+3. Analyze refactoring patterns
+4. Document current state vs original intent

+You are an elite documentation research specialist with expertise in rapidly locating and synthesizing technical documentation from multiple sources. Your primary mission is to find accurate, current documentation to support the main agent's work with maximum speed and precision.
+
+## Primary Tool Priority Matrix
+
+### Tier 1: MCP Servers (Use First - Fastest & Most Authoritative)
+1. **Context7** (`mcp__context7__*`)
+   - Use `resolve-library-id` first to get the correct library ID
+   - Then use `get-library-docs` with appropriate token limits (default: 5000, max: 10000 for complex topics)
+   - Best for: NPM packages, external libraries, frameworks
+
+2. **Angular MCP** (`mcp__angular-mcp__*`)
+   - Use `search_documentation` for Angular-specific queries
+   - Use `get_best_practices` for Angular conventions
+   - Best for: Angular APIs, components, directives, services
+
+3. **Nx MCP** (`mcp__nx-mcp__*`)
+   - Use `nx_docs` for Nx-specific documentation
+   - Use `nx_workspace` for monorepo structure understanding
+   - Best for: Nx commands, configuration, generators, executors
+
+### Tier 2: Local Documentation (Use for ISA-specific)
+- **Read tool**: For internal library READMEs (`libs/[domain]/[layer]/[feature]/README.md`)
+- **Grep tool**: For searching code patterns and examples within the project
+- **Glob tool**: For finding relevant files by pattern
+
+### Tier 3: Web Resources (Use as Fallback)
+- **WebSearch**: Official docs, GitHub repos, technical articles
+- **WebFetch**: Direct documentation pages when URL is known
+
+## Research Workflows by Query Type
+
+### Package/Library Documentation
+```
+1. Identify package name from query
+2. IF external package:
+   - Use mcp__context7__resolve-library-id
+   - Use mcp__context7__get-library-docs with focused topic
+3. IF internal ISA library:
+   - Read libs/[domain]/[layer]/[feature]/README.md
+   - Check library-reference.md for overview
+4. Extract: API surface, usage patterns, examples, version info
+```
+
+### Angular-Specific Queries
+```
+1. Use mcp__angular-mcp__search_documentation with concise query
+2. IF best practices needed:
+   - Use mcp__angular-mcp__get_best_practices
+3. Extract: Modern patterns (signals, standalone), migration notes
+4. Verify against project's Angular 20.1.2 version
+```
+
+### Nx/Monorepo Queries
+```
+1. Use mcp__nx-mcp__nx_docs with user query

+3. Extract: Commands, configuration, best practices
+```
+
+### Troubleshooting/Error Messages
+```
+1. Search error message verbatim with WebSearch
+2. Add context: "[framework] [version] [error]"
+3. Check GitHub issues for the specific library
+4. Look for: Root cause, verified solutions, workarounds
+5. Time limit: 2 minutes max before reporting findings
+```
+
+## Performance Optimization Strategies
+
+### Speed Techniques
+- **Parallel searches**: Run multiple MCP calls simultaneously when appropriate
+- **Token limits**: Start with 5000 tokens, only increase if needed
+- **Early termination**: Stop when sufficient information found
+- **Query refinement**: Use specific, technical terms over general descriptions
+
+### Avoid Redundancy
+- **Check previous context**: Don't re-fetch documentation already retrieved in conversation
+- **Summarize long docs**: Extract only relevant sections, not entire documentation
+- **Cache awareness**: Note when documentation was fetched for version currency
+
+### Time Limits
+- **MCP calls**: 10 seconds per call maximum
+- **Web searches**: 30 seconds total for web research
+- **Total research**: 2 minutes maximum before providing available findings
+
+## Enhanced Output Format
+
+```markdown

+```
+
+## ISA Frontend Project-Specific Guidelines
+
+### Version Verification
+- **Angular**: 20.1.2 (verify compatibility with docs)
+- **Nx**: 21.3.2 (check for version-specific features)
+- **Node**: ≥22.0.0 (consider for package compatibility)
+- **TypeScript**: Check tsconfig.json for version
+
+### Internal Library Research
+1. Check library-reference.md for quick overview
+2. Read the library's README.md for detailed API
+3. Look for usage examples in feature libraries
+4. Note domain-specific prefixes (oms-*, remi-*, ui-*)
+
+### Common ISA Patterns to Note
+- NgRx Signals with signalStore() (not legacy NgRx)
+- Standalone components (no NgModules)
+- Zod validation schemas
+- Tailwind with ISA-specific utilities
+- Jest → Vitest migration in progress
+
+## Error Handling & Fallback Strategies
+
+### When MCP Servers Fail
+1. Try alternative MCP server if available
+2. Fall back to WebSearch with site-specific operators
+3. Check GitHub repository directly
+4. Report: "MCP unavailable, using web sources"
+
+### When Documentation Not Found
+```markdown
+## ⚠️ Limited Documentation Available
+
+**Searched:** [List all sources checked]
+**Result:** Documentation not found or incomplete
+
+**Possible Reasons:**
+- Package may be internal/private
+- Documentation may be outdated
+- Feature might be experimental
+
+**Recommended Actions:**
+1. [Check source code directly]
+2. [Look for similar implementations]
+3. [Ask for clarification on specific aspect]
+
+## 🔄 Escalation to docs-researcher-advanced
+
+**When to escalate:**
+- Documentation not found after exhaustive search
+- Conflicting information from multiple sources
+- Need to infer API from code
+- Complex multi-system analysis required
+
+**Recommendation:** Use `docs-researcher-advanced` agent for deeper analysis with:
+- Code archaeology and inference
+- Multi-source synthesis
+- Pattern recognition
+- Documentation generation from implementation
+```
+
+### Version Mismatch Handling
+- Always note version differences
+- Highlight breaking changes prominently
+- Suggest migration paths when applicable
+- Warn about compatibility issues

+# Smart Git Commit
+
+Create well-formatted commit: $ARGUMENTS
+
+## Current Repository State
+
+- Git status: !`git status --porcelain`
+- Current branch: !`git branch --show-current`
+- Staged changes: !`git diff --cached --stat`
+- Unstaged changes: !`git diff --stat`
+- Recent commits: !`git log --oneline -5`
+
+## What This Command Does
+
+1. Unless specified with `--no-verify`, automatically runs pre-commit checks:
+   - `pnpm lint` to ensure code quality
+   - `pnpm build` to verify the build succeeds
+   - `pnpm generate:docs` to update documentation
+2. Checks which files are staged with `git status`
+3. If 0 files are staged, automatically adds all modified and new files with `git add`
+4. Performs a `git diff` to understand what changes are being committed
+5. Analyzes the diff to determine if multiple distinct logical changes are present
+6. If multiple distinct changes are detected, suggests breaking the commit into multiple smaller commits
+7. For each commit (or the single commit if not split), creates a commit message using emoji conventional commit format
+
+## Best Practices for Commits
+
+- **Verify before committing**: Ensure code is linted, builds correctly, and documentation is updated
+- **Atomic commits**: Each commit should contain related changes that serve a single purpose
+- **Split large changes**: If changes touch multiple concerns, split them into separate commits
+- **Conventional commit format**: Use the format `<type>: <description>` where type is one of:
+  - `feat`: A new feature
+  - `fix`: A bug fix
+  - `docs`: Documentation changes
+  - `style`: Code style changes (formatting, etc)
+  - `refactor`: Code changes that neither fix bugs nor add features
+  - `perf`: Performance improvements
+  - `test`: Adding or fixing tests
+  - `chore`: Changes to the build process, tools, etc.
+- **Present tense, imperative mood**: Write commit messages as commands (e.g., "add feature" not "added feature")
+- **Concise first line**: Keep the first line under 72 characters
+- **Emoji**: Each commit type is paired with an appropriate emoji:
+  - ✨ `feat`: New feature
+  - 🐛 `fix`: Bug fix
+  - 📝 `docs`: Documentation
+  - 💄 `style`: Formatting/style
+  - ♻️ `refactor`: Code refactoring
+  - ⚡️ `perf`: Performance improvements
+  - ✅ `test`: Tests

+
+## Guidelines for Splitting Commits
+
+When analyzing the diff, consider splitting commits based on these criteria:
+
+1. **Different concerns**: Changes to unrelated parts of the codebase
+2. **Different types of changes**: Mixing features, fixes, refactoring, etc.
+3. **File patterns**: Changes to different types of files (e.g., source code vs documentation)
+4. **Logical grouping**: Changes that would be easier to understand or review separately
+5. **Size**: Very large changes that would be clearer if broken down
+
+## Examples
+
+Good commit messages:
+- ✨ feat: add user authentication system
+- 🐛 fix: resolve memory leak in rendering process
+- 📝 docs: update API documentation with new endpoints
+- ♻️ refactor: simplify error handling logic in parser
+- 🚨 fix: resolve linter warnings in component files
+- 🧑‍💻 chore: improve developer tooling setup process
+- 👔 feat: implement business logic for transaction validation
+- 🩹 fix: address minor styling inconsistency in header
+- 🚑️ fix: patch critical security vulnerability in auth flow
+- 🎨 style: reorganize component structure for better readability
+- 🔥 fix: remove deprecated legacy code
+- 🦺 feat: add input validation for user registration form
+- 💚 fix: resolve failing CI pipeline tests
+- 📈 feat: implement analytics tracking for user engagement
+- 🔒️ fix: strengthen authentication password requirements
+- ♿️ feat: improve form accessibility for screen readers
+
+Example of splitting commits:
+- First commit: ✨ feat: add new solc version type definitions
+- Second commit: 📝 docs: update documentation for new solc versions
+- Third commit: 🔧 chore: update package.json dependencies
+- Fourth commit: 🏷️ feat: add type definitions for new API endpoints
+- Fifth commit: 🧵 feat: improve concurrency handling in worker threads
+- Sixth commit: 🚨 fix: resolve linting issues in new code
+- Seventh commit: ✅ test: add unit tests for new solc version features
+- Eighth commit: 🔒️ fix: update dependencies with security vulnerabilities
+
+## Command Options
+
+- `--no-verify`: Skip running the pre-commit checks (lint, build, generate:docs)
+
+## Important Notes
+
+- By default, pre-commit checks (`pnpm lint`, `pnpm build`, `pnpm generate:docs`) will run to ensure code quality
+- If these checks fail, you'll be asked if you want to proceed with the commit anyway or fix the issues first
+- If specific files are already staged, the command will only commit those files
+- If no files are staged, it will automatically stage all modified and new files
+- The commit message will be constructed based on the changes detected
+- Before committing, the command will review the diff to identify if multiple commits would be more appropriate
+- If suggesting multiple commits, it will help you stage and commit the changes separately
+- Always reviews the commit diff to ensure the message matches the changes

+# Extract from package.json and imports
+```
+
+### 10. Add E2E Attributes Documentation
+
+For UI/Feature libraries, document E2E attributes:
+```markdown
+## E2E Testing
+
+This library includes E2E test attributes for automated testing:
+
+| Element | data-what | data-which | Purpose |
+|---------|-----------|------------|---------|
+| Submit button | submit-button | form-primary | Main form submission |
+| Cancel button | cancel-button | form-primary | Cancel action |
+
+Use these attributes in your E2E tests:
+```typescript
+const submitBtn = page.locator('[data-what="submit-button"][data-which="form-primary"]');
+```
+```
+
+### 11. Generate/Update README
+
+Write or update `libs/[path]/README.md` with generated content.
+
+### 12. Validate README
+
+Checks:
+- All links work (relative paths correct)
+- Code examples are valid TypeScript
+- Import paths use correct aliases
+- No TODO or placeholder text
+- Consistent formatting
+- Proper markdown syntax
+
+### 13. Add to Git (if new)
+
+```bash
+git add libs/[path]/README.md
+```
+
+## Output Format

+# /docs:refresh-reference - Regenerate Library Reference
+
+Regenerate the library reference documentation (`docs/library-reference.md`) by scanning all libraries in the monorepo.
+
+## Tasks
+
+### 1. Scan Monorepo Structure
+```bash
+# List all libraries
+find libs/ -name "project.json" -type f | sort
+
+# Count total libraries
+find libs/ -name "project.json" -type f | wc -l
+```
+
+### 2. Extract Library Information
+
+For each library, extract from `project.json`:
+- **Project name**: `name` field
+- **Path**: Directory path
+- **Tags**: For categorization (type, domain)
+- **Targets**: Available commands (build, test, lint)
+
+### 3. Determine Path Aliases
+
+Read `tsconfig.base.json` to get path mappings:
+```bash
+# Extract paths section
+cat tsconfig.base.json | grep -A 200 '"paths"'
+```
+
+Map each library to its `@isa/*` alias.
+
+### 4. Categorize Libraries by Domain
+
+Group libraries into categories:
+- **Availability** (1 library)
+- **Catalogue** (1 library)
+- **Checkout** (6 libraries)
+- **Common** (3 libraries)
+- **Core** (5 libraries)
+- **CRM** (1 library)
+- **Icons** (1 library)
+- **OMS** (9 libraries)
+- **Remission** (8 libraries)
+- **Shared Components** (7 libraries)
+- **UI Components** (17 libraries)
+- **Utilities** (3 libraries)
+
+### 5. Read Library READMEs
+
+For each library, use `docs-researcher` agent to:
+- Read library README.md (if exists)
+- Extract description/purpose
+- Extract key features
+- Extract usage examples
+
+### 6. Generate Library Entries
+
+For each library, create entry with:
+```markdown
+#### `@isa/domain/layer/name`
+**Path:** `libs/domain/layer/name`
+**Type:** [Feature/Data Access/UI/Util]
+
+Brief description from README or inferred from structure.
+
+**Key Features:**
+- Feature 1
+- Feature 2
+
+**Usage:**
+```typescript
+import { Component } from '@isa/domain/layer/name';
+```
+```
+
+### 7. Create Domain Statistics
+
+Calculate per domain:
+- Total libraries count
+- Breakdown by type (feature/data-access/ui/util)
+- Key capabilities overview
+
+### 8. Generate Table of Contents
+
+Create hierarchical TOC:
+```markdown
+## Table of Contents
+1. [Overview](#overview)
+2. [Quick Stats](#quick-stats)
+3. [Library Categories](#library-categories)
+   - [Availability](#availability)
+   - [Catalogue](#catalogue)
+   - [Checkout](#checkout)
+   ...
+```
+
+### 9. Add Metadata Header
+
+Include document metadata:
+```markdown
+# Library Reference Guide
+
+> **Last Updated:** [Current Date]
+> **Total Libraries:** XX
+> **Domains:** 12
+
+## Quick Stats
+- Availability: 1 | Catalogue: 1 | Checkout: 6 | Common: 3
+- Core: 5 | CRM: 1 | Icons: 1 | OMS: 9 | Remission: 8
+- Shared Components: 7 | UI Components: 17 | Utilities: 3
+```
+
+### 10. Add Usage Guidelines
+
+Include quick reference section:
+```markdown
+## How to Use This Guide
+
+### Finding a Library
+1. Check the domain category (e.g., OMS, Checkout, UI Components)
+2. Look for the specific feature or component you need
+3. Note the import path alias (e.g., `@isa/oms/feature-return-search`)
+
+### Import Syntax
+All libraries use path aliases defined in `tsconfig.base.json`:
+
+```typescript
+// Feature libraries
+import { Component } from '@isa/domain/feature/name';
+
+// Data access services
+import { Service } from '@isa/domain/data-access';
+
+// UI components
+import { ButtonComponent } from '@isa/ui/buttons';
+
+// Utilities
+import { helper } from '@isa/utils/validation';
+```
+```
+
+### 11. Add Cross-References
+
+Link related libraries:
+```markdown
+**Related Libraries:**
+- [`@isa/oms/data-access`](#isaomsdataaccess) - OMS data services
+- [`@isa/ui/buttons`](#isauibuttons) - Button components
+```
+
+### 12. Include Testing Information
+
+For each library, note test framework:
+```markdown
+**Testing:** Vitest | Jest
+**Test Command:** `npx nx test [library-name] --skip-nx-cache`
+```
+
+### 13. Validate Generated Documentation
+
+Checks:
+- All libraries included (compare count)
+- All path aliases correct
+- No broken internal links
+- Consistent formatting
+- Alphabetical ordering within categories
+
+### 14. Update CLAUDE.md Reference
+
+Update CLAUDE.md to reference new library-reference.md:
+```markdown
+#### Library Reference Guide
+
+The monorepo contains **62 libraries** organized across 12 domains.
+For quick lookup, see **[`docs/library-reference.md`](docs/library-reference.md)**.
+```
+
+### 15. Create Backup
+
+Before overwriting:
+```bash
+# Backup existing file
+cp docs/library-reference.md docs/library-reference.md.backup.$(date +%s)
+```
+
+### 16. Write New Documentation
+
+Write to `docs/library-reference.md` with generated content.
+
+## Output Format
+
+**Generated File Structure:**
+```markdown
+# Library Reference Guide
+

+# End of Day Report
+
+Generate daily work summary: $ARGUMENTS
+
+## Current State
+
+- Current Date: !`date +%Y-%m-%d`
+- Current Time: !`date +%H:%M`
+- Current Branch: !`git branch --show-current`
+- Git User: !`git config user.name`
+- Git Email: !`git config user.email`
+
+## Tasks
+
+### 1. Determine Report Date and Scope
+
+**Objective**: Identify the date range for the report
+
+- [ ] Ask user for their work start time
+  - Use AskUserQuestion to ask: "What time did you start working today?"
+  - Provide options: "First commit time", "08:00", "09:00", "10:00", "Custom time"
+  - If "Custom time" selected, ask for specific time (HH:MM format)
+  - Default to first commit time if not specified
+  - Use this for accurate "Work Duration" calculation
+
+- [ ] Check if date argument provided
+  - If `[date]` provided: Use specific date (format: YYYY-MM-DD)
+  - If `--yesterday` provided: Use yesterday's date
+  - Otherwise: Use today's date
+
+```bash
+# Get today's date
+TODAY=$(date +%Y-%m-%d)
+
+# Get yesterday's date
+YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)
+
+# Get start of day
+START_TIME="${TODAY} 00:00:00"
+
+# Get end of day
+END_TIME="${TODAY} 23:59:59"
+```
+
+- [ ] Set report scope
+  - Search across **all branches** (local and remote)
+  - Filter by git user name and email
+  - Include commits from start to end of specified day
+
+### 2. Collect Commit Information
+
+**Objective**: Gather all commits made by the user on the specified date (excluding merge commits)
+
+- [ ] Fetch commits across all branches (non-merge commits only)
+
+```bash
+# Get all non-merge commits by current user today across all branches
+git log --all \
+  --author="$(git config user.name)" \
+  --since="$START_TIME" \
+  --until="$END_TIME" \
+  --pretty=format:"%h|%ai|%s|%D" \
+  --no-merges
+```
+
+**Important**: Use `--no-merges` flag to exclude PR merge commits. These will be tracked separately in section 3.
+
+- [ ] Extract commit details:
+  - Commit hash (short)
+  - Commit time
+  - Commit message
+  - Branch references (if any)
+
+- [ ] Group commits by branch
+  - Parse branch references from commit output
+  - Identify which branch each commit belongs to
+  - Track branch switches during the day
+  - Exclude "Merged PR" commits from this section (they appear in Merge Activity instead)
+
+**Example Output**:
+```
+c208327db|2025-10-28 14:23:45|feat(crm-data-access,checkout): improve primary bonus card selection logic|feature/5202-Praemie
+9020cb305|2025-10-28 10:15:32|✨ feat(navigation): implement title management and enhance tab system|feature/5351-navigation
+```
+
+### 3. Identify PR and Merge Activity
+
+**Objective**: Find pull requests created or merged today, distinguishing between PRs I merged vs PRs merged by colleagues
+
+- [ ] Find ALL merge commits with "Merged PR" (check both author and committer)
+
+```bash
+# Get all PR merge activity with author and committer info
+git log --all \
+  --since="$START_TIME" \
+  --until="$END_TIME" \
+  --grep="Merged PR" \
+  --pretty=format:"%h|%ai|%s|Author: %an <%ae>|Committer: %cn <%ce>"
+```
+
+- [ ] Categorize PR merges:
+  - **PRs I merged**: Where I am the COMMITTER (git config user.name matches committer name)
+  - **My PRs merged by colleagues**: Where I am the AUTHOR but someone else is the COMMITTER
+  - **Colleague PRs I merged**: Where someone else is the AUTHOR and I am the COMMITTER
+
+- [ ] Parse PR numbers from commit messages
+  - Look for patterns: "Merged PR 1234:", "PR #1234", etc.
+  - Extract PR title/description
+  - Note which branch was merged
+  - Note who performed the merge (committer name)
+
+- [ ] Identify branch merges
+  - Look for merge commits to develop/main
+  - Note feature branches merged
+
+### 4. Analyze Branch Activity
+
+**Objective**: Summarize branches worked on today
+
+- [ ] List all branches with commits today
+
+```bash
+# Get unique branches with activity today
+git log --all \
+  --author="$(git config user.name)" \
+  --since="$START_TIME" \
+  --until="$END_TIME" \
+  --pretty=format:"%D" | \
+  grep -v '^$' | \
+  tr ',' '\n' | \
+  sed 's/^ *//' | \
+  grep -E '^(origin/)?[a-zA-Z]' | \
+  sort -u
+```
+
+- [ ] Identify:
+  - Primary branch worked on (most commits)
+  - Other branches touched
+  - New branches created today
+  - Branches merged today
+
+- [ ] Check current branch status
+  - Uncommitted changes
+  - Untracked files
+  - Ahead/behind develop
+
+### 5. Generate Report Summary
+
+**Objective**: Create formatted markdown report
+
+- [ ] Build report structure:
+
+```markdown
+# End of Day Report - YYYY-MM-DD
+
+**Developer**: [Name] <email>
+**Date**: Day, Month DD, YYYY
+**Time**: HH:MM
+

+
+- [ ] Check if version argument provided
+  - If `[version]` provided: Use as the new version number
+  - If `--since [tag]` provided: Use custom tag as starting point
+  - Otherwise: Use latest tag as starting point
+
+```bash
+# Find latest tag
+LATEST_TAG=$(git tag --sort=-creatordate | head -n 1)
+
+# Get commits since tag
+git log ${LATEST_TAG}..HEAD --oneline
+
+# If no tags exist, use entire history
+if [ -z "$LATEST_TAG" ]; then
+  git log --oneline
+fi
+```
+
+**Edge Cases**:
+- No tags exist → Use entire commit history and suggest version 0.1.0
+- No commits since last tag → Notify user, no changelog needed
+- Invalid tag provided → Error with available tags list
+
+### 2. Extract and Categorize Commits
+
+**Objective**: Parse commit messages and group by Keep a Changelog categories
+
+- [ ] Fetch commits with detailed information
+
+```bash
+# Get commits with format: hash | date | message
+git log ${LATEST_TAG}..HEAD --pretty=format:"%h|%as|%s" --no-merges
+```
+
+- [ ] Parse conventional commit patterns and map to categories:
+
+**Mapping Rules**:
+- `feat:` or `feature:` → **Added**
+- `fix:` or `bugfix:` → **Fixed**
+- `refactor:` → **Changed**
+- `perf:` or `performance:` → **Changed**
+- `docs:` → **Changed** (or skip if only documentation)
+- `style:` → **Changed**
+- `test:` → (skip from changelog)
+- `chore:` → (skip from changelog)
+- `build:` or `ci:` → (skip from changelog)
+- `revert:` → **Changed** or **Fixed**
+- `security:` → **Security**
+- `deprecate:` or `deprecated:` → **Deprecated**
+- `remove:` or `breaking:` → **Removed**
+- Non-conventional commits → **Changed** (default)
+
+- [ ] Extract scope and description from commit messages
+
+**Commit Pattern**: `type(scope): description`
+
+Example:
+```
+feat(checkout): add reward delivery order support
+fix(remission): resolve currency constraint violations
+refactor(navigation): implement title management system
+```
+
+### 3. Generate Changelog Entry
+
+**Objective**: Create properly formatted changelog section
+
+- [ ] Determine version number
+  - Use provided `[version]` argument
+  - Or prompt for new version if not provided
+  - Format: `[X.Y.Z]` following semantic versioning
+
+- [ ] Get current date in ISO format: `YYYY-MM-DD`
+
+```bash
+TODAY=$(date +%Y-%m-%d)
+```
+
+- [ ] Build changelog entry following Keep a Changelog format:
+
+```markdown
+## [VERSION] - YYYY-MM-DD
+
+### Added
+- New feature description from feat: commits
+- Another feature
+
+### Changed
+- Refactored component description
+- Performance improvements
+
+### Deprecated
+- Feature marked for removal
+
+### Removed
+- Deleted feature or breaking change
+
+### Fixed
+- Bug fix description
+- Another fix
+
+### Security
+- Security improvement description
+```
+
+**Rules**:
+- Only include sections that have entries
+- Sort entries alphabetically within each section
+- Use sentence case for descriptions
+- Remove commit type prefix from descriptions
+- Include scope in parentheses if present: `(scope) description`
+- Add reference links to commits/PRs if available
+
+### 4. Update or Preview CHANGELOG.md
+
+**Objective**: Append new entry to changelog file or show preview
+
+**If `--dry-run` flag provided**:
+- [ ] Display generated changelog entry to stdout
+- [ ] Show preview of where it would be inserted
+- [ ] Do NOT modify CHANGELOG.md
+- [ ] Exit with success
+
+**Otherwise (append mode)**:
+- [ ] Check if CHANGELOG.md exists
+  - If not, create with standard header:
+
+```markdown
+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+```
+
+- [ ] Read existing CHANGELOG.md content
+- [ ] Find insertion point (after "## [Unreleased]" section, or after main header)
+- [ ] Insert new changelog entry
+- [ ] Maintain reverse chronological order (newest first)
+- [ ] Write updated content back to CHANGELOG.md
+
+```bash
+# Backup existing file
+cp CHANGELOG.md CHANGELOG.md.bak
+
+# Insert new entry
+# (Implementation handled by Edit tool)
+```
+
+### 5. Validate and Report
+
+**Objective**: Verify changelog quality and provide summary
+
+- [ ] Validate generated entry:
+  - Version format is valid (X.Y.Z)
+  - Date is correct (YYYY-MM-DD)
+  - At least one category has entries
+  - No duplicate entries
+  - Proper markdown formatting
+
+- [ ] Report statistics:
+  - Number of commits processed
+  - Entries per category
+  - Version number used
+  - File status (preview/updated)
+
+- [ ] Show next steps:
+  - Review changelog entry
+  - Update version in package.json if needed
+  - Create git tag if appropriate
+  - Commit changelog changes

+# /quality:bundle-analyze - Analyze Bundle Sizes
+
+Analyze production bundle sizes and provide optimization recommendations. Project thresholds: 2MB warning, 5MB error.
+
+## Tasks
+
+### 1. Run Production Build
+```bash
+# Clean previous build
+rm -rf dist/
+
+# Build for production
+npm run build-prod
+```
+
+### 2. Analyze Bundle Output
+```bash
+# List bundle files with sizes
+ls -lh dist/apps/isa-app/browser/*.js | awk '{print $9, $5}'
+
+# Get total bundle size
+du -sh dist/apps/isa-app/browser/
+```
+
+### 3. Identify Large Files
+Parse build output and identify:
+- Main bundle size
+- Lazy-loaded chunk sizes
+- Vendor chunks
+- Files exceeding thresholds:
+  - **Warning**: > 2MB
+  - **Error**: > 5MB
+
+### 4. Analyze Dependencies
+```bash
+# Check for duplicate dependencies
+npm ls --depth=0 | grep -E "UNMET|deduped"
+
+# Show largest node_modules packages
+du -sh node_modules/* | sort -rh | head -20
+```
+
+### 5. Source Map Analysis
+Use source maps to identify large contributors:
+```bash
+# Install source-map-explorer if needed
+npm install -g source-map-explorer
+
+# Analyze main bundle
+source-map-explorer dist/apps/isa-app/browser/main.*.js
+```
+
+### 6. Generate Recommendations
+Based on analysis, provide actionable recommendations:
+
+**If bundle > 2MB:**
+- Identify heavy dependencies to replace or remove
+- Suggest lazy loading opportunities
+- Check for unused imports
+
+**Code Splitting Opportunities:**
+- Large feature modules that could be lazy-loaded
+- Heavy libraries that could be dynamically imported
+- Vendor code that could be split into separate chunks
+
+**Dependency Optimization:**
+- Replace large libraries with smaller alternatives
+- Remove unused dependencies
+- Use tree-shakeable imports
+
+**Build Configuration:**
+- Enable/optimize compression
+- Check for source maps in production (should be disabled)
+- Verify optimization flags
+
+### 7. Comparative Analysis
+If previous build data exists:
+```bash
+# Compare with previous build
+# (Requires manual tracking or CI/CD integration)
+echo "Current build: $(du -sh dist/apps/isa-app/browser/ | awk '{print $1}')"
+```
+
+### 8. Generate Report
+Create formatted report with:
+- Total bundle size with threshold status (✅ < 2MB, ⚠️ 2-5MB, ❌ > 5MB)
+- Main bundle and largest chunks
+- Top 10 largest dependencies
+- Optimization recommendations prioritized by impact
+- Lazy loading opportunities
+
+## Output Format
+```
+Bundle Analysis Report
+======================
+
+Total Size: X.XX MB [STATUS]
+Main Bundle: X.XX MB
+Largest Chunks:
+  - chunk-name.js: X.XX MB
+  - ...
+
+Largest Dependencies:
+  1. dependency-name: X.XX MB
+  ...
+
+Recommendations:
+🔴 Critical (> 5MB):
+  - [Action items]
+
+⚠️ Warning (2-5MB):
+  - [Action items]
+
+✅ Optimization Opportunities:
+  - [Action items]
+
+Lazy Loading Candidates:
+  - [Feature modules]
+```
+
+## Error Handling
+- Build failures: Show error and suggest fixes
+- Missing tools: Offer to install (source-map-explorer)
+- No dist folder: Run build first

+# /quality:coverage - Generate Test Coverage Report
+
+Generate comprehensive test coverage report with recommendations for improving coverage.
+
+## Parameters
+- `library-name` (optional): Specific library to analyze. If omitted, analyzes all libraries.
+
+## Tasks
+
+### 1. Run Coverage Analysis
+```bash
+# Single library
+npx nx test [library-name] --skip-nx-cache --coverage
+
+# All libraries (if no library specified)
+npm run ci # Runs all tests with coverage
+```
+
+### 2. Parse Coverage Report
+Coverage output typically in:
+- `coverage/libs/[domain]/[layer]/[name]/`
+- Look for `coverage-summary.json` or text output
+
+Extract metrics:
+- **Line coverage**: % of executable lines tested
+- **Branch coverage**: % of conditional branches tested
+- **Function coverage**: % of functions called in tests
+- **Statement coverage**: % of statements executed
+
+### 3. Identify Uncovered Code
+Parse coverage report to find:
+- **Uncovered files**: Files with 0% coverage
+- **Partially covered files**: < 80% coverage
+- **Uncovered lines**: Specific line numbers not tested
+- **Uncovered branches**: Conditional paths not tested
+
+```bash
+# List files with coverage below 80%
+# (Parse from coverage JSON output)
+```
+
+### 4. Categorize Coverage Gaps
+
+**Critical (High Risk):**
+- Service methods handling business logic
+- Data transformation functions
+- Error handling code paths
+- Security-related functions
+- State management store actions
+
+**Important (Medium Risk):**
+- Component public methods
+- Utility functions
+- Validators
+- Pipes and filters
+- Guard functions
+
+**Low Priority:**
+- Getters/setters
+- Simple property assignments
+- Console logging
+- Type definitions
+
+### 5. Generate Recommendations
+
+For each coverage gap, provide:
+- **File and line numbers**
+- **Risk level** (Critical/Important/Low)
+- **Suggested test type** (unit/integration)
+- **Test approach** (example test scenario)
+
+Example:
+```
+📍 libs/oms/data-access/src/lib/services/order.service.ts:45-52
+🔴 Critical - Business Logic
+❌ 0% coverage - Error handling path
+
+Recommended test:
+it('should handle API error when fetching order', async () => {
+  // Mock API to return error
+  // Call method
+  // Verify error handling
+});
+```
+
+### 6. Calculate Coverage Trends
+If historical data available:
+- Compare with previous coverage percentage
+- Show improvement/regression
+- Identify files with declining coverage
+
+### 7. Generate HTML Report
+```bash
+# Open coverage report in browser (if available)
+open coverage/libs/[domain]/[layer]/[name]/index.html
+```
+
+### 8. Create Coverage Summary Report
+
+**Overall Metrics:**
+```
+Coverage Summary for [library-name]
+====================================
+
+Line Coverage:     XX.X% (XXX/XXX lines)
+Branch Coverage:   XX.X% (XXX/XXX branches)
+Function Coverage: XX.X% (XXX/XXX functions)
+Statement Coverage: XX.X% (XXX/XXX statements)
+
+Target: 80% (Recommended minimum)
+Status: ✅ Met / ⚠️ Below Target / 🔴 Critical
+```
+
+**Files Needing Attention:**
+```
+🔴 Critical (< 50% coverage):
+  1. service-name.service.ts - 35% (business logic)
+  2. data-processor.ts - 42% (transformations)
+
+⚠️ Below Target (50-79% coverage):
+  3. component-name.component.ts - 68%
+  4. validator.ts - 72%
+
+✅ Well Covered (≥ 80% coverage):
+  - Other files maintaining good coverage
+```
+
+**Top Priority Tests to Add:**
+1. [File:Line] - [Description] - [Risk Level]
+2. ...
+
+### 9. Framework-Specific Notes
+
+**Vitest:**
+- Coverage provider: v8 or istanbul
+- Config in `vitest.config.ts`
+- Coverage thresholds configurable
+
+**Jest:**
+- Coverage collected via `--coverage` flag
+- Config in `jest.config.ts`
+- Coverage directory: `coverage/`
+
+### 10. Set Coverage Thresholds (Optional)
+Suggest adding to test config:
+```typescript
+// vitest.config.ts
+coverage: {
+  thresholds: {
+    lines: 80,
+    functions: 80,
+    branches: 80,
+    statements: 80
+  }
+}
+```
+
+## Output Format
+```

+name: angular-template
+description: This skill should be used when writing or reviewing Angular component templates. It provides guidance on modern Angular 20+ template syntax including control flow (@if, @for, @switch, @defer), content projection (ng-content), template references (ng-template, ng-container), variable declarations (@let), and expression binding. Use when creating components, refactoring to modern syntax, implementing lazy loading, or reviewing template best practices.
+---
+
+# Angular Template
+
+Guide for modern Angular 20+ template patterns: control flow, lazy loading, projection, and binding.
+
+## When to Use
+
+- Creating/reviewing component templates
+- Refactoring legacy `*ngIf/*ngFor/*ngSwitch` to modern syntax
+- Implementing `@defer` lazy loading
+- Designing reusable components with `ng-content`
+- Template performance optimization
+
+**Related Skills:** These skills work together when writing Angular templates:
+- **[html-template](../html-template/SKILL.md)** - E2E testing attributes (`data-what`, `data-which`) and ARIA accessibility
+- **[tailwind](../tailwind/SKILL.md)** - ISA design system styling (colors, typography, spacing, layout)
+
+## Control Flow (Angular 17+)
+
+### @if / @else if / @else
+
+```typescript
+@if (user.isAdmin()) {
+  <app-admin-dashboard />
+} @else if (user.isEditor()) {
+  <app-editor-dashboard />
+} @else {
+  <app-viewer-dashboard />
+}
+
+// Store result with 'as'
+@if (user.profile?.settings; as settings) {
+  <p>Theme: {{settings.theme}}</p>
+}
+```
+
+### @for with @empty
+
+```typescript
+@for (product of products(); track product.id) {
+  <app-product-card [product]="product" />
+} @empty {
+  <p>No products available</p>
+}
+```
+
+**CRITICAL:** Always provide `track` expression:
+- Best: `track item.id` or `track item.uuid`
+- Static lists: `track $index`
+- **NEVER:** `track identity(item)` (causes full re-render)
+
+**Contextual variables:** `$count`, `$index`, `$first`, `$last`, `$even`, `$odd`
+
+### @switch
+
+```typescript
+@switch (viewMode()) {
+  @case ('grid') { <app-grid-view /> }
+  @case ('list') { <app-list-view /> }
+  @default { <app-grid-view /> }
+}
+```
+
+## @defer Lazy Loading
+
+### Basic Usage
+
+```typescript
+@defer (on viewport) {
+  <app-heavy-chart />
+} @placeholder (minimum 500ms) {
+  <div class="skeleton"></div>
+} @loading (after 100ms; minimum 1s) {
+  <mat-spinner />
+} @error {
+  <p>Failed to load</p>
+}
+```
+
+### Triggers
+
+| Trigger | Use Case |
+|---------|----------|
+| `idle` (default) | Non-critical features |
+| `viewport` | Below-the-fold content |
+| `interaction` | User-initiated (click/keydown) |
+| `hover` | Tooltips/popovers |
+| `timer(Xs)` | Delayed content |
+| `when(expr)` | Custom condition |
+
+**Multiple triggers:** `@defer (on interaction; on timer(5s))`
+**Prefetching:** `@defer (on interaction; prefetch on idle)`
+
+### Requirements
+
+- Components **MUST be standalone**
+- No `@ViewChild`/`@ContentChild` references
+- Reserve space in `@placeholder` to prevent layout shift
+
+### Best Practices
+
+- ✅ Defer below-the-fold content
+- ❌ Never defer above-the-fold (harms LCP)
+- ❌ Avoid `immediate`/`timer` during initial render (harms TTI)
+- Test with network throttling
+
+## Content Projection
+
+### Single Slot
+
+```typescript
+@Component({
+  selector: 'ui-card',
+  template: `<div class="card"><ng-content></ng-content></div>`
+})
+```
+
+### Multi-Slot with Selectors
+
+```typescript
+@Component({
+  template: `
+    <header><ng-content select="card-header"></ng-content></header>
+    <main><ng-content select="card-body"></ng-content></main>
+    <footer><ng-content></ng-content></footer> <!-- default slot -->
+  `
+})
+```
+
+**Usage:**
+```html
+<ui-card>
+  <card-header><h3>Title</h3></card-header>
+  <card-body><p>Content</p></card-body>
+  <button>Action</button> <!-- goes to default slot -->
+</ui-card>
+```
+
+**Fallback content:** `<ng-content select="title">Default Title</ng-content>`
+**Aliasing:** `<h3 ngProjectAs="card-header">Title</h3>`
+
+### CRITICAL Constraint
+
+`ng-content` **always instantiates** (even if hidden). For conditional projection, use `ng-template` + `NgTemplateOutlet`.
+
+## Template References
+
+### ng-template
+
+```html
+<ng-template #userCard let-user="userData" let-index="i">
+  <div class="user">#{{index}}: {{user.name}}</div>
+</ng-template>
+
+<ng-container
+  *ngTemplateOutlet="userCard; context: {userData: currentUser(), i: 0}">
+</ng-container>
+```
+
+**Access in component:**
+```typescript
+myTemplate = viewChild<TemplateRef<unknown>>('myTemplate');
+```
+
+### ng-container
+
+Groups elements without DOM footprint:
+
+```html
+<p>
+  Hero's name is
+  <ng-container @if="hero()">{{hero().name}}</ng-container>.
+</p>
+```
+
+## Variables
+
+### @let (Angular 18.1+)
+
+```typescript
+@let userName = user().name;
+@let greeting = 'Hello, ' + userName;
+@let asyncData = data$ | async;
+
+<h1>{{greeting}}</h1>
+```
+
+**Scoped to current view** (not hoisted to parent/sibling).
+
+### Template References (#)
+
+```html
+<input #emailInput type="email" />
+<button (click)="sendEmail(emailInput.value)">Send</button>
+
+<app-datepicker #startDate />
+<button (click)="startDate.open()">Open</button>
+```
+
+## Binding Patterns
+
+**Property:** `[disabled]="!isValid()"`
+**Attribute:** `[attr.aria-label]="label()"` `[attr.data-what]="'card'"`
+**Event:** `(click)="save()"` `(input)="onInput($event)"`
+**Two-way:** `[(ngModel)]="userName"`
+**Class:** `[class.active]="isActive()"` or `[class]="{active: isActive()}"`
+**Style:** `[style.width.px]="width()"` or `[style]="{color: textColor()}"`
+
+## Best Practices
+
+1. **Use signals:** `isExpanded = signal(false)`
+2. **Prefer control flow over directives:** Use `@if` not `*ngIf`
+3. **Keep expressions simple:** Use `computed()` for complex logic
+4. **Testing & Accessibility:** Always add E2E and ARIA attributes (see **[html-template](../html-template/SKILL.md)** skill)
+5. **Track expressions:** Required in `@for`, use unique IDs
+
+## Migration
+
+| Legacy | Modern |
+|--------|--------|
+| `*ngIf="condition"` | `@if (condition) { }` |
+| `*ngFor="let item of items"` | `@for (item of items; track item.id) { }` |
+| `[ngSwitch]` | `@switch (value) { @case ('a') { } }` |
+
+**CLI migration:** `ng generate @angular/core:control-flow`

+# Control Flow Reference
+
+Advanced patterns for `@if`, `@for`, `@switch`.
+
+## @if Patterns
+
+### Store Results with `as`
+
+```typescript
+@if (user.profile?.settings?.theme; as theme) {
+  <p>Theme: {{theme}}</p>
+}
+
+@if (data$ | async; as data) {
+  <app-list [items]="data.items" />
+}
+```
+
+### Complex Conditions
+
+```typescript
+@if (isAdmin() && hasPermission('edit')) {
+  <button (click)="edit()">Edit</button>
+}
+
+@if (user()?.role === 'admin' || user()?.role === 'moderator') {
+  <app-moderation-panel />
+}
+```
+
+## @for Patterns
+
+### Contextual Variables
+
+```typescript
+@for (user of users(); track user.id) {
+  <tr [class.odd]="$odd">
+    <td>{{$index + 1}}</td>
+    <td>{{user.name}}</td>
+    <td>{{$count}} total</td>
+    @if ($first) { <span>First</span> }
+  </tr>
+}
+```
+
+### Track Strategies
+
+```typescript
+// ✅ Best: Unique ID
+@for (order of orders(); track order.uuid) { }
+
+// ✅ Good: Composite key
+@for (item of items(); track item.categoryId + '-' + item.id) { }
+
+// ⚠️ OK: Index (static only)
+@for (color of ['red', 'blue']; track $index) { }
+
+// ❌ NEVER: Identity function
+@for (item of items(); track identity(item)) { }
+```
+
+### Nested Loops
+
+```typescript
+@for (category of categories(); track category.id) {
+  <div class="category">
+    <h3>{{category.name}}</h3>
+    @for (product of category.products; track product.id) {
+      <app-product [product]="product" [categoryIdx]="$index" />
+    }
+  </div>
+}
+```
+
+### Filter in Component
+
+```typescript
+// Component
+activeUsers = computed(() => this.users().filter(u => u.isActive));
+
+// Template
+@for (user of activeUsers(); track user.id) {
+  <app-user-card [user]="user" />
+} @empty {
+  <p>No active users</p>
+}
+```
+
+## @switch Patterns
+
+### Basic Switch
+
+```typescript
+@switch (viewMode()) {
+  @case ('grid') { <app-grid-view /> }
+  @case ('list') { <app-list-view /> }
+  @case ('table') { <app-table-view /> }
+  @default { <app-grid-view /> }
+}
+```
+
+### Nested Switch
+
+```typescript
+@switch (category()) {
+  @case ('electronics') {
+    @switch (subcategory()) {
+      @case ('phones') { <app-phone-list /> }
+      @case ('laptops') { <app-laptop-list /> }
+      @default { <app-electronics-list /> }
+    }
+  }
+  @case ('clothing') { <app-clothing-list /> }
+  @default { <app-all-categories /> }
+}
+```
+
+### Combined with Other Control Flow
+
+```typescript
+@switch (status()) {
+  @case ('loading') { <mat-spinner /> }
+  @case ('success') {
+    @if (data()?.length) {
+      @for (item of data(); track item.id) {
+        <app-item [item]="item" />
+      }
+    } @else {
+      <p>No data</p>
+    }
+  }
+  @case ('error') { <app-error [message]="errorMessage()" /> }
+}
+```
+
+## Common Patterns
+
+### Loading State
+
+```typescript
+@if (isLoading()) {
+  <mat-spinner />
+} @else if (error()) {
+  <app-error [error]="error()" (retry)="loadData()" />
+} @else {
+  @for (item of items(); track item.id) {
+    <app-item [item]="item" />
+  } @empty {
+    <app-empty-state />
+  }
+}
+```
+
+### Tab Navigation
+
+```typescript
+<nav>
+  @for (tab of tabs(); track tab.id) {
+    <button [class.active]="activeTab() === tab.id" (click)="setActiveTab(tab.id)">
+      {{tab.label}}
+    </button>
+  }
+</nav>
+
+@switch (activeTab()) {
+  @case ('profile') { <app-profile /> }
+  @case ('settings') { <app-settings /> }
+  @default { <app-profile /> }
+}
+```
+
+### Hierarchical Data
+
+```typescript
+@for (section of sections(); track section.id) {
+  <details [open]="section.isExpanded">
+    <summary>{{section.title}} ({{section.items.length}})</summary>
+    @for (item of section.items; track item.id) {
+      <div>{{item.name}}</div>
+    } @empty {
+      <p>No items</p>
+    }
+  </details>
+}
+```

+# @defer Patterns
+
+Lazy loading strategies and performance optimization.
+
+## Basic Patterns
+
+### Complete State Management
+
+```typescript
+@defer (on viewport) {
+  <app-product-reviews [productId]="productId()" />
+} @placeholder (minimum 500ms) {
+  <div class="skeleton" style="height: 400px;"></div>
+} @loading (after 100ms; minimum 1s) {
+  <mat-spinner />
+} @error {
+  <p>Failed to load reviews</p>
+  <button (click)="retry()">Retry</button>
+}
+```
+
+## Triggers
+
+### Common Strategies
+
+```typescript
+// Idle: Non-critical features
+@defer (on idle) { <app-recommendations /> }
+
+// Viewport: Below-the-fold
+@defer (on viewport) { <app-comments /> }
+
+// Interaction: User-initiated
+@defer (on interaction) { <app-filters /> }
+
+// Hover: Tooltips/popovers
+@defer (on hover) { <app-user-tooltip /> }
+
+// Timer: Delayed content
+@defer (on timer(3s)) { <app-promo-banner /> }
+
+// When: Custom condition
+@defer (when userLoggedIn()) { <app-personalized-content /> }
+```
+
+### Multiple Triggers
+
+```typescript
+// OR logic: first trigger wins
+@defer (on interaction; on timer(5s)) {
+  <app-newsletter-signup />
+}
+```
+
+### Prefetching
+
+```typescript
+// Load JS on idle, show on interaction
+@defer (on interaction; prefetch on idle) {
+  <app-video-player />
+}
+
+// Load JS on hover, show on click
+@defer (on interaction; prefetch on hover) {
+  <app-modal />
+}
+```
+
+## Performance Patterns
+
+### Bundle Size Reduction
+
+```typescript
+<div class="product-page">
+  <!-- Critical: Load immediately -->
+  <app-product-header [product]="product()" />
+
+  <!-- Heavy chart: Defer on viewport -->
+  @defer (on viewport) {
+    <app-analytics-chart />
+  } @placeholder {
+    <div style="height: 300px;"></div>
+  }
+
+  <!-- Video player: Defer on interaction -->
+  @defer (on interaction; prefetch on idle) {
+    <app-video-player />
+  } @placeholder {
+    <img [src]="videoThumbnail" />
+  }
+</div>
+```
+
+### Staggered Loading
+
+```typescript
+<div class="dashboard">
+  <app-header /> <!-- Immediate -->
+
+  @defer (on idle) {
+    <app-key-metrics /> <!-- Important -->
+  }
+
+  @defer (on viewport) {
+    <app-recent-activity /> <!-- Secondary -->
+  } @placeholder {
+    <div style="height: 400px;"></div>
+  }
+
+  @defer (on viewport) {
+    <app-analytics /> <!-- Tertiary -->
+  } @placeholder {
+    <div style="height: 300px;"></div>
+  }
+</div>
+```
+
+### Conditional Defer (Mobile Only)
+
+```typescript
+// Component
+shouldDefer = computed(() => this.breakpoint([Breakpoint.Tablet]));
+
+// Template
+@if (shouldDefer()) {
+  @defer (on viewport) { <app-heavy-chart /> }
+} @else {
+  <app-heavy-chart />
+}
+```
+
+## Requirements
+
+### Must Be Standalone
+
+```typescript
+// ✅ Valid
+@Component({ standalone: true })
+export class ChartComponent {}
+
+@defer { <app-chart /> } // Will defer
+
+// ❌ Invalid
+@NgModule({ declarations: [ChartComponent] })
+@defer { <app-chart /> } // Won't defer! Loads eagerly
+```
+
+### No External References
+
+```typescript
+// ❌ Invalid: ViewChild reference
+@ViewChild('chart') chart!: ChartComponent;
+@defer { <app-chart #chart /> } // ERROR
+
+// ✅ Valid: Use events
+@defer {
+  <app-chart (dataLoaded)="onChartLoaded($event)" />
+}
+```
+
+## Core Web Vitals
+
+### Prevent Layout Shift (CLS)
+
+```typescript
+// ✅ Reserve exact height
+@defer (on viewport) {
+  <app-large-component />
+} @placeholder {
+  <div style="height: 600px;"></div>
+}
+
+// ❌ No height reserved
+@defer (on viewport) {
+  <app-large-component />
+} @placeholder {
+  <p>Loading...</p> // Causes layout shift
+}
+```
+
+### Don't Defer LCP Elements
+
+```typescript
+// ❌ BAD: Hero image deferred
+@defer (on idle) {
+  <img src="hero.jpg" /> <!-- LCP element! -->
+}
+
+// ✅ GOOD: Load immediately
+<img src="hero.jpg" />
+
+@defer (on viewport) {
+  <app-below-fold-content />
+}
+```
+
+### Improve Time to Interactive (TTI)
+
+```typescript
+// Critical: Immediate
+<button (click)="addToCart()">Add to Cart</button>
+
+// Non-critical: Defer
+@defer (on idle) {
+  <app-social-share />
+}
+```
+
+## Common Pitfalls
+
+### 1. Cascading Defer (Bad)
+
+```typescript
+// ❌ Sequential loads
+@defer (on idle) {
+  <div>
+    @defer (on idle) {
+      <div>
+        @defer (on idle) { <app-nested /> }
+      </div>
+    }
+  </div>
+}
+
+// ✅ Single defer
+@defer (on idle) {
+  <div><div><app-nested /></div></div>
+}
+```
+
+### 2. Above-Fold Defer
+
+```typescript
+// ❌ Above-fold content deferred
+<header>
+  @defer (on idle) {
+    <nav>...</nav> <!-- Should load immediately -->
+  }
+</header>
+
+// ✅ Below-fold only
+<header><nav>...</nav></header>
+<main>
+  @defer (on viewport) {
+    <app-below-fold />
+  }
+</main>
+```
+
+### 3. Missing Minimum Durations
+
+```typescript
+// ❌ Flickers quickly
+@defer {
+  <app-fast-component />
+} @loading {
+  <mat-spinner /> <!-- Flashes briefly -->
+}
+
+// ✅ Smooth loading
+@defer {
+  <app-fast-component />
+} @loading (after 100ms; minimum 500ms) {
+  <mat-spinner />
+}
+```
+
+## Real-World Example
+
+```typescript
+<div class="product-page">
+  <!-- Critical: Immediate -->
+  <app-product-header />
+  <app-product-images />
+  <app-add-to-cart />
+
+  <!-- Important: Idle -->
+  @defer (on idle) {
+    <app-product-description />
+  }
+
+  <!-- Below fold: Viewport -->
+  @defer (on viewport) {
+    <app-reviews />
+  } @placeholder {
+    <div style="min-height: 400px;"></div>
+  }
+
+  <!-- Optional: Interaction -->
+  @defer (on interaction; prefetch on idle) {
+    <app-size-guide />
+  } @placeholder {
+    <button>View Size Guide</button>
+  }
+
+  <!-- Related: Viewport -->
+  @defer (on viewport) {
+    <app-related-products />
+  }
+</div>
+```

+# Content Projection Patterns
+
+Advanced `ng-content`, `ng-template`, and `ng-container` techniques.
+
+## Basic Projection
+
+### Single Slot
+
+```typescript
+@Component({
+  selector: 'ui-panel',
+  template: `<div class="panel"><ng-content></ng-content></div>`
+})
+export class PanelComponent {}
+```
+
+### Multi-Slot with Selectors
+
+```typescript
+@Component({
+  selector: 'ui-card',
+  template: `
+    <header><ng-content select="card-header"></ng-content></header>
+    <main><ng-content select="card-body"></ng-content></main>
+    <footer><ng-content></ng-content></footer> <!-- default -->
+  `
+})
+```
+
+**Usage:**
+```html
+<ui-card>
+  <card-header><h3>Title</h3></card-header>
+  <card-body><p>Content</p></card-body>
+  <button>Action</button> <!-- default slot -->
+</ui-card>
+```
+
+**Selectors:** Element (`card-title`), class (`.actions`), attribute (`[slot='footer']`)
+**Fallback:** `<ng-content select="title">Default</ng-content>`
+**Aliasing:** `<h3 ngProjectAs="card-header">Title</h3>`
+
+## Conditional Projection
+
+`ng-content` always instantiates (even if hidden). Use `ng-template` for truly conditional content:
+
+```typescript
+@Component({
+  selector: 'ui-expandable',
+  imports: [NgTemplateOutlet],
+  template: `
+    <div (click)="toggle()">
+      <ng-content select="header"></ng-content>
+      <span>{{ isExpanded() ? '▼' : '▶' }}</span>
+    </div>
+    @if (isExpanded()) {
+      <ng-container *ngTemplateOutlet="contentTemplate()"></ng-container>
+    }
+  `
+})
+export class ExpandableComponent {
+  isExpanded = signal(false);
+  contentTemplate = contentChild<TemplateRef<unknown>>('content');
+  toggle() { this.isExpanded.update(v => !v); }
+}
+```
+
+**Usage:**
+```html
+<ui-expandable>
+  <header><h3>Click to expand</h3></header>
+  <ng-template #content>
+    <app-heavy-component /> <!-- Only rendered when expanded -->
+  </ng-template>
+</ui-expandable>
+```
+
+## Template-Based Projection
+
+### Accepting Template Fragments
+
+```typescript
+@Component({
+  selector: 'ui-list',
+  imports: [NgTemplateOutlet],
+  template: `
+    <ul>
+      @for (item of items(); track item.id) {
+        <li>
+          <ng-container
+            *ngTemplateOutlet="itemTemplate(); context: { $implicit: item, index: $index }">
+          </ng-container>
+        </li>
+      }
+    </ul>
+  `
+})
+export class ListComponent<T> {
+  items = input.required<T[]>();
+  itemTemplate = contentChild.required<TemplateRef<{ $implicit: T; index: number }>>('itemTemplate');
+}
+```
+
+**Usage:**
+```html
+<ui-list [items]="users()">
+  <ng-template #itemTemplate let-user let-i="index">
+    <div>{{i + 1}}. {{user.name}}</div>
+  </ng-template>
+</ui-list>
+```
+
+### Multiple Template Slots
+
+```typescript
+@Component({
+  selector: 'ui-data-table',
+  imports: [NgTemplateOutlet],
+  template: `
+    <table>
+      <thead><ng-container *ngTemplateOutlet="headerTemplate()"></ng-container></thead>
+      <tbody>
+        @for (row of data(); track row.id) {
+          <ng-container *ngTemplateOutlet="rowTemplate(); context: { $implicit: row }"></ng-container>
+        }
+      </tbody>
+      <tfoot><ng-container *ngTemplateOutlet="footerTemplate()"></ng-container></tfoot>
+    </table>
+  `
+})
+export class DataTableComponent<T> {
+  data = input.required<T[]>();
+  headerTemplate = contentChild.required<TemplateRef<void>>('header');
+  rowTemplate = contentChild.required<TemplateRef<{ $implicit: T }>>('row');
+  footerTemplate = contentChild<TemplateRef<void>>('footer');
+}
+```
+
+## Querying Projected Content
+
+### Using ContentChildren
+
+```typescript
+@Component({
+  selector: 'ui-tabs',
+  template: `
+    <nav>
+      @for (tab of tabs(); track tab.id) {
+        <button [class.active]="tab === activeTab()" (click)="selectTab(tab)">
+          {{tab.label()}}
+        </button>
+      }
+    </nav>
+    <ng-content></ng-content>
+  `
+})
+export class TabsComponent {
+  tabs = contentChildren(TabComponent);
+  activeTab = signal<TabComponent | null>(null);
+
+  ngAfterContentInit() {
+    this.selectTab(this.tabs()[0]);
+  }
+
+  selectTab(tab: TabComponent) {
+    this.tabs().forEach(t => t.isActive.set(false));
+    tab.isActive.set(true);
+    this.activeTab.set(tab);
+  }
+}
+
+@Component({
+  selector: 'ui-tab',
+  template: `@if (isActive()) { <ng-content></ng-content> }`
+})
+export class TabComponent {
+  label = input.required<string>();
+  isActive = signal(false);
+  id = Math.random().toString(36);
+}
+```
+
+## Real-World Examples
+
+### Modal/Dialog
+
+```typescript
+@Component({
+  selector: 'ui-modal',
+  imports: [NgTemplateOutlet],
+  template: `
+    @if (isOpen()) {
+      <div class="backdrop" (click)="close()">
+        <div class="modal" (click)="$event.stopPropagation()">
+          <header>
+            <ng-content select="modal-title"></ng-content>
+            <button (click)="close()">×</button>
+          </header>
+          <main><ng-content></ng-content></main>
+          <footer>
+            <ng-content select="modal-actions">
+              <button (click)="close()">Close</button>
+            </ng-content>
+          </footer>
+        </div>
+      </div>
+    }
+  `
+})
+export class ModalComponent {
+  isOpen = signal(false);
+  open() { this.isOpen.set(true); }
+  close() { this.isOpen.set(false); }
+}
+```
+
+### Form Field Wrapper
+
+```typescript
+@Component({
+  selector: 'ui-form-field',
+  template: `
+    <div class="form-field" [class.has-error]="error()">
+      <label [for]="fieldId()">
+        <ng-content select="field-label"></ng-content>
+        @if (required()) { <span class="required">*</span> }
+      </label>
+      <div class="input-wrapper"><ng-content></ng-content></div>
+      @if (error()) { <span class="error">{{error()}}</span> }
+      @if (hint()) { <span class="hint">{{hint()}}</span> }
+    </div>
+  `
+})
+export class FormFieldComponent {
+  fieldId = input.required<string>();
+  required = input(false);
+  error = input<string>();
+  hint = input<string>();
+}
+```
+
+## Performance Notes
+
+- `ng-content` **always instantiates** projected content
+- For conditional projection, use `ng-template` + `NgTemplateOutlet`
+- Projected content evaluates in **parent component context**
+- Use `computed()` for expensive expressions in projected content
+
+## Common Pitfalls
+
+1. **Using ng-content in structural directives:** Won't work as expected. Use `ng-template` instead.
+2. **Forgetting default slot:** Unmatched content disappears without default `<ng-content></ng-content>`
+3. **Template order matters:** Content renders in template order, not usage order

+  <h3>Template content</h3>
+  <p>Not rendered until explicitly instantiated</p>
+</ng-template>
+```
+
+### Rendering with NgTemplateOutlet

+
+### Passing Context
+
+```html
+<ng-template #userCard let-user="user" let-index="idx">
+  <div>#{{index}}: {{user.name}}</div>
+</ng-template>
+
+<ng-container
+  *ngTemplateOutlet="userCard; context: {user: currentUser(), idx: 0}">
+</ng-container>
+```
+
+**$implicit for default parameter:**
+
+```html
+<ng-template #simple let-value>
+  <p>{{value}}</p>
+</ng-template>
+
+<ng-container *ngTemplateOutlet="simple; context: {$implicit: 'Hello'}">
+</ng-container>
+```
+
+## Accessing Templates
+
+### ViewChild
+
+```typescript
+@Component({
+  template: `
+    <ng-template #myTemplate><p>Content</p></ng-template>
+    <button (click)="render()">Render</button>
+  `
+})
+export class MyComponent {
+  myTemplate = viewChild<TemplateRef<unknown>>('myTemplate');
+  viewContainer = inject(ViewContainerRef);
+
+  render() {
+    this.viewContainer.createEmbeddedView(this.myTemplate()!);
+  }
+}
+```
+
+### ContentChild
+
+```typescript
+@Component({
+  selector: 'ui-dialog',
+  template: `<ng-container *ngTemplateOutlet="contentTemplate()"></ng-container>`
+})
+export class DialogComponent {
+  contentTemplate = contentChild<TemplateRef<unknown>>('content');
+}
+```
+
+**Usage:**
+```html
+<ui-dialog>
+  <ng-template #content>
+    <h2>Dialog Content</h2>
+  </ng-template>
+</ui-dialog>
+```
+
+## Programmatic Rendering
+
+### ViewContainerRef
+
+```typescript
+@Component({
+  template: `
+    <ng-template #dynamic let-title>
+      <h2>{{title}}</h2>
+    </ng-template>
+    <button (click)="addView()">Add</button>
+  `
+})
+export class DynamicComponent {
+  dynamic = viewChild<TemplateRef<{ $implicit: string }>>('dynamic');
+  viewContainer = inject(ViewContainerRef);
+  views: EmbeddedViewRef<any>[] = [];
+
+  addView() {
+    const view = this.viewContainer.createEmbeddedView(
+      this.dynamic()!,
+      { $implicit: `View ${this.views.length + 1}` }
+    );
+    this.views.push(view);
+  }
+}
+```
+
+### Custom Directive
+
+```typescript
+@Directive({ selector: '[appDynamicHost]', standalone: true })
+export class DynamicHostDirective {
+  viewContainer = inject(ViewContainerRef);
+
+  render(template: TemplateRef<any>, context?: any) {
+    this.viewContainer.clear();
+    this.viewContainer.createEmbeddedView(template, context);
+  }
+}
+```
+
+## ng-container Patterns
+
+Groups elements without DOM node:
+
+```html
+<!-- Without extra wrapper -->
+<p>
+  Hero's name is
+  <ng-container @if="hero()">{{hero().name}}</ng-container>.
+</p>
+```
+
+### Use Cases
+
+**1. Structural directives without wrappers:**
+```html
+<div>
+  <ng-container @if="showSection()">
+    <h2>Title</h2>
+    <p>Content</p>
+  </ng-container>
+</div>
+```
+
+**2. Grouping multiple elements:**
+```html
+<ul>
+  @for (category of categories(); track category.id) {
+    <ng-container>
+      <li class="header">{{category.name}}</li>
+      @for (item of category.items; track item.id) {
+        <li>{{item.name}}</li>
+      }
+    </ng-container>
+  }
+</ul>
+```
+
+**3. Conditional options:**
+```html
+<select [(ngModel)]="value">
+  @for (group of groups(); track group.id) {
+    <optgroup [label]="group.label">
+      @for (opt of group.options; track opt.id) {
+        <ng-container @if="opt.isEnabled">
+          <option [value]="opt.value">{{opt.label}}</option>
+        </ng-container>
+      }
+    </optgroup>
+  }
+</select>
+```
+
+**4. Template outlets:**
+```html
+<div>
+  <ng-container *ngTemplateOutlet="header()"></ng-container>
+  <main><ng-container *ngTemplateOutlet="content()"></ng-container></main>
+  <ng-container *ngTemplateOutlet="footer()"></ng-container>
+</div>
+```
+
+**5. ViewContainerRef injection:**
+```typescript
+@Directive({ selector: '[appDynamic]', standalone: true })
+export class DynamicDirective {
+  viewContainer = inject(ViewContainerRef); // Injects at ng-container
+}
+```
+
+```html
+<ng-container appDynamic></ng-container>
+```
+
+## Advanced Patterns
+
+### Reusable Repeater
+
+```typescript
+@Component({
+  selector: 'ui-repeater',
+  imports: [NgTemplateOutlet],
+  template: `
+    @for (item of items(); track trackBy(item)) {
+      <ng-container
+        *ngTemplateOutlet="itemTemplate(); context: { $implicit: item, index: $index }">
+      </ng-container>
+    }
+  `
+})
+export class RepeaterComponent<T> {
+  items = input.required<T[]>();
+  itemTemplate = contentChild.required<TemplateRef<{ $implicit: T; index: number }>>('item');
+  trackBy = input<(item: T) => any>((item: any) => item);
+}
+```
+
+### Template Polymorphism
+
+```typescript
+@Component({
+  selector: 'ui-card-list',
+  imports: [NgTemplateOutlet],
+  template: `
+    @for (item of items(); track item.id) {
+      @switch (item.type) {
+        @case ('product') {
+          <ng-container *ngTemplateOutlet="productTpl(); context: { $implicit: item }"></ng-container>
+        }
+        @case ('service') {
+          <ng-container *ngTemplateOutlet="serviceTpl(); context: { $implicit: item }"></ng-container>
+        }
+        @default {
+          <ng-container *ngTemplateOutlet="defaultTpl(); context: { $implicit: item }"></ng-container>
+        }
+      }
+    }
+  `
+})
+export class CardListComponent {
+  items = input.required<Item[]>();
+  productTpl = contentChild.required<TemplateRef<{ $implicit: Item }>>('product');
+  serviceTpl = contentChild.required<TemplateRef<{ $implicit: Item }>>('service');
+  defaultTpl = contentChild.required<TemplateRef<{ $implicit: Item }>>('default');
+}
+```
+
+## Context Scoping
+
+Templates evaluate in **declaration context**, not render context:
+
+```typescript
+@Component({
+  selector: 'parent',
+  template: `
+    <ng-template #tpl>
+      <p>{{parentValue()}}</p> <!-- Evaluates in parent -->
+    </ng-template>
+    <child [template]="tpl"></child>
+  `
+})
+export class ParentComponent {
+  parentValue = signal('Parent');
+}
+
+@Component({
+  selector: 'child',
+  imports: [NgTemplateOutlet],
+  template: `<ng-container *ngTemplateOutlet="template()"></ng-container>`
+})
+export class ChildComponent {
+  template = input.required<TemplateRef<void>>();
+}
+```
+
+**Override with context:**
+```typescript
+<ng-container
+  *ngTemplateOutlet="template(); context: { childData: childValue() }">
+</ng-container>
+```
+
+## Common Pitfalls
+
+1. **Forgetting context:** `<ng-container *ngTemplateOutlet="tpl"></ng-container>` without context won't pass data
+2. **Styling ng-container:** Not in DOM, can't be styled
+3. **Template timing:** Access templates in `ngAfterViewInit`, not constructor
+4. **Confusing ng-template vs ng-content:** Template = reusable fragment, Content = projects parent content

+description: This skill should be used when analyzing Swagger/OpenAPI specification changes BEFORE regenerating API clients. It compares old vs new specs, categorizes changes as breaking/compatible/warnings, finds affected code, and generates migration strategies. Use this skill when the user wants to check API changes safely before sync, mentions "check breaking changes", or needs impact assessment.
+---
+
+# API Change Analyzer
+
+## Overview
+
+Analyze Swagger/OpenAPI specification changes to detect breaking changes before regeneration. Provides detailed comparison, impact analysis, and migration recommendations.
+
+## When to Use This Skill
+
+Invoke when user wants to:
+- Check API changes before regeneration
+- Assess impact of backend updates
+- Plan migration for breaking changes
+- Mentioned "breaking changes" or "API diff"
+
+## Analysis Workflow
+
+### Step 1: Backup and Generate Temporarily
+
+```bash
+cp -r generated/swagger/[api-name] /tmp/[api-name].backup
+npm run generate:swagger:[api-name]
+```
+
+### Step 2: Compare Files
+
+```bash
+diff -u /tmp/[api-name].backup/models.ts generated/swagger/[api-name]/models.ts
+diff -u /tmp/[api-name].backup/services.ts generated/swagger/[api-name]/services.ts
+```
+
+### Step 3: Categorize Changes
+
+**🔴 Breaking (Critical):**
+- Removed properties from response models
+- Changed property types (string → number)
+- Removed endpoints
+- Optional → required fields
+- Removed enum values
+
+**✅ Compatible (Safe):**
+- Added properties (non-breaking)
+- New endpoints
+- Added optional parameters
+- New enum values
+
+**⚠️ Warnings (Review):**
+- Property renamed (old removed + new added)
+- Changed default values
+- Changed validation rules
+- Added required request fields
+
+### Step 4: Analyze Impact
+
+For each breaking change, use `Explore` agent to find usages:
+
+```bash
+# Example: Find usages of removed property
+grep -r "removedProperty" libs/*/data-access --include="*.ts"
+```
+
+List:
+- Affected files
+- Services impacted
+- Estimated refactoring effort
+
+### Step 5: Generate Migration Strategy
+
+Based on severity:
+
+**High Impact (multiple breaking changes):**
+1. Create migration branch
+2. Document all changes
+3. Update services incrementally
+4. Comprehensive testing
+
+**Medium Impact:**
+1. Fix compilation errors
+2. Update affected tests
+3. Deploy with monitoring
+
+**Low Impact:**
+1. Minor updates
+2. Deploy
+
+### Step 6: Create Report
+
+```

+description: This skill should be used when validating import boundaries and architectural rules in the ISA-Frontend monorepo. It checks for circular dependencies, layer violations (Feature→Feature), domain violations (OMS→Remission), and relative imports. Use this skill when the user wants to check architecture, mentions "validate boundaries", "check imports", or needs dependency analysis.
+---
+
+# Architecture Enforcer
+
+## Overview
+
+Validate and enforce architectural boundaries in the monorepo. Checks import rules, detects violations, generates dependency graphs, and suggests refactoring.
+
+## When to Use This Skill
+
+Invoke when user wants to:
+- Validate import boundaries
+- Check architectural rules
+- Find dependency violations
+- Mentioned "check architecture" or "validate imports"
+
+## Architectural Rules
+
+**✅ Allowed:**
+- Feature → Data Access
+- Feature → UI
+- Feature → Util
+- Data Access → Util
+
+**❌ Forbidden:**
+- Feature → Feature
+- Data Access → Feature
+- UI → Feature
+- Cross-domain (OMS ↔ Remission)
+
+## Enforcement Workflow
+
+### Step 1: Run Nx Dependency Checks
+
+```bash
+# Lint all (includes boundary checks)
+npx nx run-many --target=lint --all
+
+# Or specific library
+npx nx lint [library-name]
+```
+
+### Step 2: Generate Dependency Graph
+
+```bash
+# Visual graph
+npx nx graph
+
+# Focus on specific project
+npx nx graph --focus=[library-name]
+
+# Affected projects
+npx nx affected:graph
+```
+
+### Step 3: Scan for Violations
+
+**Check for Circular Dependencies:**
+Use `Explore` agent to find A→B→A patterns.
+
+**Check Layer Violations:**
+```bash
+# Find feature-to-feature imports
+grep -r "from '@isa/[^/]*/feature" libs/*/feature/ --include="*.ts"
+```
+
+**Check Relative Imports:**
+```bash
+# Should use path aliases, not relative
+grep -r "from '\.\./\.\./\.\." libs/ --include="*.ts"
+```
+
+**Check Direct Swagger Imports:**
+```bash
+# Should go through data-access
+grep -r "from '@generated/swagger" libs/*/feature/ --include="*.ts"
+```
+
+### Step 4: Categorize Violations
+
+**🔴 Critical:**
+- Circular dependencies
+- Feature → Feature
+- Data Access → Feature
+- Cross-domain dependencies
+
+**⚠️ Warnings:**
+- Relative imports (should use aliases)
+- Missing tags in project.json
+- Deep import paths
+
+**ℹ️ Info:**
+- Potential shared utilities
+
+### Step 5: Generate Violation Report
+
+For each violation:
+```
+📍 libs/oms/feature/return-search/src/lib/component.ts:12
+🔴 Layer Violation
+❌ Feature importing from another feature
+
+Import: import { OrderList } from '@isa/oms/feature-order-list';
+Issue: Feature libraries should not depend on other features
+Fix: Move shared component to @isa/shared/* or @isa/ui/*
+```
+
+### Step 6: Suggest Refactoring
+
+**For repeated patterns:**
+- Create shared library for common components
+- Extract shared utilities to util library
+- Move API clients to data-access layer
+- Create facade services
+
+### Step 7: Visualize Problems
+
+```bash
+npx nx graph --focus=[problematic-library]
+```
+
+### Step 8: Generate Report
+
+```

+description: This skill should be used when detecting and resolving circular dependencies in the ISA-Frontend monorepo. It uses graph algorithms to find A→B→C→A cycles, categorizes by severity, provides multiple fix strategies (DI, interface extraction, shared code), and validates fixes. Use this skill when the user mentions "circular dependencies", "dependency cycles", or has build/runtime issues from circular imports.

+
+# Circular Dependency Resolver
+
+## Overview
+
+Detect and resolve circular dependencies using graph analysis, multiple fix strategies, and automated validation. Prevents runtime and build issues caused by dependency cycles.
+
+## When to Use This Skill
+
+Invoke when user:
+- Mentions "circular dependencies"
+- Has import cycle errors
+- Requests dependency analysis
+- Build fails with circular import warnings
+
+## Resolution Workflow
+
+### Step 1: Detect Circular Dependencies
+
+**Using Nx:**
+```bash
+npx nx run-many --target=lint --all 2>&1 | grep -i "circular"
+```
+
+**Using madge (if installed):**
+```bash
+npm install -g madge
+madge --circular --extensions ts libs/
+madge --circular --image circular-deps.svg libs/
+```
+
+**Using TypeScript:**
+```bash
+npx tsc --noEmit --strict 2>&1 | grep -i "circular\|cycle"
+```
+
+### Step 2: Analyze Each Cycle
+
+For each cycle found:
+```
+📍 Circular Dependency Detected
+
+Cycle Path:
+1. libs/oms/data-access/src/lib/services/order.service.ts
+   → imports OrderValidator
+2. libs/oms/data-access/src/lib/validators/order.validator.ts
+   → imports OrderService
+3. Back to order.service.ts
+
+Type: Service-Validator circular reference
+Severity: 🔴 Critical
+Files Involved: 2
+```
+
+### Step 3: Categorize by Severity
+
+**🔴 Critical (Must Fix):**
+- Service-to-service cycles
+- Data-access layer cycles
+- Store dependencies creating cycles
+
+**⚠️ Warning (Should Fix):**
+- Component-to-component cycles
+- Model cross-references
+- Utility function cycles
+
+**ℹ️ Info (Review):**
+- Type-only circular references (may be acceptable)
+- Test file circular imports
+
+### Step 4: Choose Fix Strategy
+
+**Strategy 1: Extract to Shared Utility**
+```typescript
+// BEFORE (Circular)
+// order.service.ts imports validator.ts
+// validator.ts imports order.service.ts
+
+// AFTER (Fixed)
+// Create @isa/oms/util/types.ts
+export interface OrderData { id: string; }
+
+// order.service.ts imports types
+// validator.ts imports types
+// No more cycle
+```
+
+**Strategy 2: Dependency Injection (Lazy)**
+```typescript
+// BEFORE
+import { ServiceB } from './service-b';
+export class ServiceA {
+  constructor(private serviceB: ServiceB) {}
+}
+
+// AFTER
+import { Injector } from '@angular/core';
+export class ServiceA {
+  private serviceB!: ServiceB;
+
+  constructor(private injector: Injector) {
+    setTimeout(() => {
+      this.serviceB = this.injector.get(ServiceB);
+    });
+  }
+}
+```
+
+**Strategy 3: Interface Extraction**
+```typescript
+// BEFORE (Models with circular reference)
+// order.ts ↔ customer.ts
+
+// AFTER
+// order.interface.ts - no imports
+export interface IOrder { customerId: string; }
+
+// customer.interface.ts - no imports
+export interface ICustomer { orderIds: string[]; }
+
+// order.ts imports only ICustomer
+// customer.ts imports only IOrder
+```
+
+**Strategy 4: Move Shared Code**
+```typescript
+// BEFORE
+// feature-a imports feature-b
+// feature-b imports feature-a
+
+// AFTER
+// Extract to @isa/shared/[name]
+// Both features import from shared
+```
+
+**Strategy 5: Forward References (Angular)**
+```typescript
+// Use forwardRef for components
+import { forwardRef } from '@angular/core';
+
+@Component({
+  imports: [forwardRef(() => ChildComponent)]
+})
+```
+
+### Step 5: Implement Fix
+
+Apply chosen strategy:
+1. Create new files if needed (util library, interfaces)
+2. Update imports in both files
+3. Remove circular import
+
+### Step 6: Validate Fix
+
+```bash
+# Check cycle resolved
+madge --circular --extensions ts libs/
+
+# TypeScript compilation
+npx tsc --noEmit
+
+# Run tests
+npx nx affected:test --skip-nx-cache
+
+# Lint
+npx nx affected:lint
+```
+
+### Step 7: Generate Report
+
+```

+description: Enforces ISA-Frontend project Git workflow conventions including branch naming, conventional commits, and PR creation against develop branch
+---
+
+# Git Workflow Skill
+
+Enforces Git workflow conventions specific to the ISA-Frontend project.
+
+## When to Use
+
+- Creating new branches for features or bugfixes
+- Writing commit messages
+- Creating pull requests
+- Any Git operations requiring adherence to project conventions
+
+## Core Principles
+
+### 1. Default Branch is `develop` (NOT `main`)
+
+- **All PRs target**: `develop` branch
+- **Feature branches from**: `develop`
+- **Never push directly to**: `develop` or `main`
+
+### 2. Branch Naming Convention
+
+**Format**: `<type>/{task-id}-{short-description}`
+
+**Types**:
+- `feature/` - New features or enhancements
+- `bugfix/` - Bug fixes
+- `hotfix/` - Emergency production fixes
+
+**Rules**:
+- Use English kebab-case for descriptions
+- Start with task/issue ID (e.g., `5391`)
+- Keep description concise - shorten if too long
+- Use hyphens to separate words
+
+**Examples**:
+```bash
+# Good
+feature/5391-praemie-checkout-action-card-delivery-order
+bugfix/6123-fix-login-redirect-loop
+hotfix/7890-critical-payment-error
+
+# Bad

+
+# HTML Template - Testing & Accessibility Attributes
+
+This skill should be used when writing or reviewing HTML templates to ensure proper testing and accessibility attributes are included.
+
+## When to Use This Skill
+
+Use this skill when:
+- Writing or modifying Angular component templates
+- Creating any HTML templates or markup
+- Reviewing code for testing and accessibility compliance
+- Adding interactive elements (buttons, inputs, links, etc.)
+- Implementing forms, lists, navigation, or dialogs
+
+**Works seamlessly with:**
+- **[angular-template](../angular-template/SKILL.md)** - Angular template syntax, control flow, and modern patterns
+- **[tailwind](../tailwind/SKILL.md)** - ISA design system styling for visual design
+
+## Overview
+
+This skill provides comprehensive guidance for two critical HTML attribute categories:
+
+### 1. E2E Testing Attributes
+Enable automated end-to-end testing by providing stable selectors for QA automation:
+- **`data-what`**: Semantic description of element's purpose
+- **`data-which`**: Unique identifier for specific instances
+- **`data-*`**: Additional contextual information
+
+### 2. ARIA Accessibility Attributes
+Ensure web applications are accessible to all users, including those using assistive technologies:
+- **Roles**: Define element purpose (button, navigation, dialog, etc.)
+- **Properties**: Provide additional context (aria-label, aria-describedby)
+- **States**: Indicate dynamic states (aria-expanded, aria-disabled)
+- **Live Regions**: Announce dynamic content changes
+
+## Why Both Are Essential
+
+- **E2E Attributes**: Enable reliable automated testing without brittle CSS or XPath selectors
+- **ARIA Attributes**: Ensure compliance with WCAG standards and improve user experience for people with disabilities
+- **Together**: Create robust, testable, and accessible web applications
+
+## Quick Reference
+
+### Button Example
+```html
+<button
+  type="button"
+  (click)="onSubmit()"
+  data-what="submit-button"
+  data-which="registration-form"
+  aria-label="Submit registration form">
+  Submit
+</button>
+```
+
+### Input Example
+```html
+<input
+  type="text"
+  [(ngModel)]="email"
+  data-what="email-input"
+  data-which="registration-form"
+  aria-label="Email address"
+  aria-describedby="email-hint"
+  aria-required="true" />
+<span id="email-hint">We'll never share your email</span>
+```
+
+### Dynamic List Example
+```html
+@for (item of items; track item.id) {
+  <li
+    (click)="selectItem(item)"
+    data-what="list-item"
+    [attr.data-which]="item.id"
+    [attr.data-status]="item.status"
+    [attr.aria-label]="'Select ' + item.name"
+    role="button"
+    tabindex="0">
+    {{ item.name }}
+  </li>
+}
+```
+
+### Link Example
+```html
+<a
+  [routerLink]="['/orders', orderId]"
+  data-what="order-link"
+  [attr.data-which]="orderId"
+  [attr.aria-label]="'View order ' + orderNumber">
+  View Order #{{ orderNumber }}
+</a>
+```
+
+### Dialog Example
+```html
+<div
+  class="dialog"
+  data-what="confirmation-dialog"
+  data-which="delete-item"
+  role="dialog"
+  aria-modal="true"
+  aria-labelledby="dialog-title"
+  aria-describedby="dialog-description">
+
+  <h2 id="dialog-title">Confirm Deletion</h2>
+  <p id="dialog-description">Are you sure you want to delete this item?</p>
+
+  <button
+    (click)="confirm()"
+    data-what="confirm-button"
+    data-which="delete-dialog"
+    aria-label="Confirm deletion">
+    Delete
+  </button>
+
+  <button
+    (click)="cancel()"
+    data-what="cancel-button"
+    data-which="delete-dialog"
+    aria-label="Cancel deletion">
+    Cancel
+  </button>
+</div>
+```
+
+## Common Patterns by Element Type
+
+### Interactive Elements That Need Attributes
+
+**Required attributes for:**
+- Buttons (`<button>`, `<ui-button>`, custom button components)
+- Form inputs (`<input>`, `<textarea>`, `<select>`)
+- Links (`<a>`, `[routerLink]`)
+- Clickable elements (elements with `(click)` handlers)
+- Custom interactive components
+- List items in dynamic lists
+- Navigation items
+- Dialog/modal controls
+
+### Naming Conventions
+
+**E2E `data-what` patterns:**
+- `*-button` (submit-button, cancel-button, delete-button)
+- `*-input` (email-input, search-input, quantity-input)
+- `*-link` (product-link, order-link, customer-link)
+- `*-item` (list-item, menu-item, card-item)
+- `*-dialog` (confirm-dialog, error-dialog, info-dialog)
+- `*-dropdown` (status-dropdown, category-dropdown)
+
+**E2E `data-which` guidelines:**
+- Use unique identifiers: `data-which="primary"`, `data-which="customer-list"`
+- Bind dynamically for lists: `[attr.data-which]="item.id"`
+- Combine with context: `data-which="customer-{{ customerId }}-edit"`
+
+**ARIA role patterns:**
+- Interactive elements: `button`, `link`, `menuitem`
+- Structural: `navigation`, `main`, `complementary`, `contentinfo`
+- Widget: `dialog`, `alertdialog`, `tooltip`, `tablist`, `tab`
+- Landmark: `banner`, `search`, `form`, `region`
+
+## Best Practices
+
+### E2E Attributes
+1. ✅ Add to ALL interactive elements
+2. ✅ Use kebab-case for `data-what` values
+3. ✅ Ensure `data-which` is unique within the view
+4. ✅ Use Angular binding for dynamic values: `[attr.data-*]`
+5. ✅ Avoid including sensitive data in attributes
+6. ✅ Document complex attribute patterns in template comments
+
+### ARIA Attributes
+1. ✅ Use semantic HTML first (use `<button>` instead of `<div role="button">`)
+2. ✅ Provide text alternatives for all interactive elements
+3. ✅ Ensure proper keyboard navigation (tabindex, focus management)
+4. ✅ Use `aria-label` when visual label is missing
+5. ✅ Use `aria-labelledby` to reference existing visible labels
+6. ✅ Keep ARIA attributes in sync with visual states
+7. ✅ Test with screen readers (NVDA, JAWS, VoiceOver)
+
+### Combined Best Practices
+1. ✅ Add both E2E and ARIA attributes to every interactive element
+2. ✅ Keep attributes close together in the HTML for readability
+3. ✅ Update tests to use `data-what` and `data-which` selectors
+4. ✅ Validate coverage: all interactive elements should have both types
+5. ✅ Review with QA and accessibility teams

+## Validation Checklist
+
+Before considering template complete:
+- [ ] All buttons have `data-what`, `data-which`, and `aria-label`
+- [ ] All inputs have `data-what`, `data-which`, and appropriate ARIA attributes
+- [ ] All links have `data-what`, `data-which`, and descriptive ARIA labels
+- [ ] Dynamic lists use `[attr.data-*]` bindings with unique identifiers
+- [ ] Dialogs have proper ARIA roles and relationships
+- [ ] Forms have proper field associations and error announcements
+- [ ] Interactive elements are keyboard accessible (tabindex where needed)
+- [ ] No duplicate `data-which` values within the same view
+- [ ] Screen reader testing completed (if applicable)
+
+## Example: Complete Form
+
+```html
+<form
+  data-what="registration-form"
+  data-which="user-signup"
+  role="form"
+  aria-labelledby="form-title">
+
+  <h2 id="form-title">User Registration</h2>
+
+  <div class="form-field">
+    <label for="username-input">Username</label>
+    <input
+      id="username-input"
+      type="text"
+      [(ngModel)]="username"
+      data-what="username-input"
+      data-which="registration-form"
+      aria-required="true"
+      aria-describedby="username-hint" />
+    <span id="username-hint">Must be at least 3 characters</span>
+  </div>
+
+  <div class="form-field">
+    <label for="email-input">Email</label>
+    <input
+      id="email-input"
+      type="email"
+      [(ngModel)]="email"
+      data-what="email-input"
+      data-which="registration-form"
+      aria-required="true"
+      [attr.aria-invalid]="emailError ? 'true' : null"
+      aria-describedby="email-error" />
+    @if (emailError) {
+      <span
+        id="email-error"
+        role="alert"
+        aria-live="polite">
+        {{ emailError }}
+      </span>
+    }
+  </div>
+
+  <div class="form-actions">
+    <button
+      type="submit"
+      (click)="onSubmit()"
+      data-what="submit-button"
+      data-which="registration-form"
+      [attr.aria-disabled]="!isValid"
+      aria-label="Submit registration form">
+      Register
+    </button>
+
+    <button
+      type="button"
+      (click)="onCancel()"
+      data-what="cancel-button"
+      data-which="registration-form"
+      aria-label="Cancel registration">
+      Cancel
+    </button>
+  </div>
+</form>
+```
+
+## Remember
+
+- **Always use both E2E and ARIA attributes together**
+- **E2E attributes enable automated testing** - your QA team relies on them
+- **ARIA attributes enable accessibility** - legal requirement and right thing to do
+- **Test with real users and assistive technologies** - automated checks aren't enough
+- **Keep attributes up-to-date** - maintain as code changes
+
+---
+
+**This skill works automatically with Angular templates. Both E2E and ARIA attributes should be added to every interactive element.**

+
+## Overview
+
+E2E testing attributes provide stable, semantic selectors for automated testing. They enable QA automation without relying on brittle CSS classes, IDs, or XPath selectors that frequently break when styling changes.
+
+## Core Attribute Types
+
+### 1. `data-what` (Required)
+**Purpose**: Semantic description of the element's purpose or type
+
+**Format**: kebab-case string
+
+**Examples**:
+- `data-what="submit-button"`
+- `data-what="search-input"`
+- `data-what="product-link"`
+- `data-what="list-item"`
+
+**Guidelines**:
+- Describes WHAT the element is or does
+- Should be consistent across similar elements
+- Use descriptive, semantic names
+- Keep it concise but clear
+
+### 2. `data-which` (Required)
+**Purpose**: Unique identifier for the specific instance of this element type
+
+**Format**: kebab-case string or dynamic binding
+
+**Examples**:
+- `data-which="primary"` (static)
+- `data-which="customer-form"` (static)
+- `[attr.data-which]="item.id"` (dynamic)
+- `[attr.data-which]="'customer-' + customerId"` (dynamic with context)
+
+**Guidelines**:
+- Identifies WHICH specific instance of this element type
+- Must be unique within the same view/component
+- Use dynamic binding for list items: `[attr.data-which]="item.id"`
+- Can combine multiple identifiers: `data-which="customer-123-edit"`
+
+### 3. `data-*` (Contextual)
+**Purpose**: Additional contextual information about state, status, or data
+
+**Format**: Custom attributes with kebab-case names
+
+**Examples**:
+- `data-status="active"`
+- `data-index="0"`
+- `data-role="admin"`
+- `[attr.data-count]="items.length"`
+
+**Guidelines**:
+- Use for additional context that helps testing
+- Avoid sensitive data (passwords, tokens, PII)
+- Use Angular binding for dynamic values: `[attr.data-*]`
+- Keep attribute names semantic and clear
+
+## Why E2E Attributes?
+
+### Problems with Traditional Selectors
+
+**CSS Classes (Bad)**:
+```html
+<!-- Brittle - breaks when styling changes -->
+<button class="btn btn-primary submit">Submit</button>
+```
+```javascript
+// Test breaks when class names change
+await page.click('.btn-primary.submit');
+```
+
+**XPath (Bad)**:
+```javascript
+// Brittle - breaks when structure changes
+await page.click('//div[@class="form"]/button[2]');
+```
+
+**IDs (Better, but limited)**:
+```html
+<!-- IDs must be unique across entire page -->
+<button id="submit-btn">Submit</button>
+```
+
+### Benefits of E2E Attributes
+
+**Stable, Semantic Selectors (Good)**:
+```html
+<button
+  class="btn btn-primary"
+  data-what="submit-button"
+  data-which="registration-form">
+  Submit
+</button>
+```
+```javascript
+// Stable - survives styling and structure changes
+await page.click('[data-what="submit-button"][data-which="registration-form"]');
+```
+
+**Advantages**:
+- ✅ Decoupled from styling (CSS classes can change freely)
+- ✅ Semantic and self-documenting
+- ✅ Consistent across the application
+- ✅ Easy to read and maintain
+- ✅ Survives refactoring and restructuring
+- ✅ QA and developers speak the same language
+
+## Naming Conventions
+
+### Common `data-what` Patterns
+
+| Pattern | Use Case | Examples |
+|---------|----------|----------|
+| `*-button` | All button elements | `submit-button`, `cancel-button`, `delete-button`, `save-button` |
+| `*-input` | Text inputs and textareas | `email-input`, `search-input`, `quantity-input`, `password-input` |
+| `*-select` | Dropdown/select elements | `status-select`, `category-select`, `country-select` |
+| `*-checkbox` | Checkbox inputs | `terms-checkbox`, `subscribe-checkbox`, `remember-checkbox` |
+| `*-radio` | Radio button inputs | `payment-radio`, `shipping-radio` |
+| `*-link` | Navigation links | `product-link`, `order-link`, `customer-link`, `home-link` |
+| `*-item` | List/grid items | `list-item`, `menu-item`, `card-item`, `row-item` |
+| `*-dialog` | Modals and dialogs | `confirm-dialog`, `error-dialog`, `info-dialog` |
+| `*-dropdown` | Dropdown menus | `actions-dropdown`, `filter-dropdown` |
+| `*-toggle` | Toggle switches | `theme-toggle`, `notifications-toggle` |
+| `*-tab` | Tab navigation | `profile-tab`, `settings-tab` |
+| `*-badge` | Status badges | `status-badge`, `count-badge` |
+| `*-icon` | Interactive icons | `close-icon`, `menu-icon`, `search-icon` |
+
+### `data-which` Naming Guidelines
+
+**Static unique identifiers** (single instance):
+- `data-which="primary"` - Primary action button
+- `data-which="secondary"` - Secondary action button
+- `data-which="main-search"` - Main search input
+- `data-which="customer-form"` - Customer form context
+
+**Dynamic identifiers** (multiple instances):
+- `[attr.data-which]="item.id"` - List item by ID
+- `[attr.data-which]="'product-' + product.id"` - Product item
+- `[attr.data-which]="index"` - By array index (use sparingly)
+
+**Contextual identifiers** (combine context):
+- `data-which="customer-{{ customerId }}-edit"` - Edit button for specific customer
+- `data-which="order-{{ orderId }}-cancel"` - Cancel button for specific order
+
+## Patterns by Element Type
+
+### Buttons
+
+```html
+<!-- Submit Button -->
+<button
+  type="submit"
+  (click)="onSubmit()"
+  data-what="submit-button"
+  data-which="registration-form">

+</button>
+
+<!-- Cancel Button -->
+<button
+  type="button"
+  (click)="onCancel()"
+  data-what="cancel-button"
+  data-which="registration-form">
+  Cancel
+</button>
+
+<!-- Delete Button with Confirmation -->
+<button
+  (click)="onDelete(item)"
+  data-what="delete-button"
+  [attr.data-which]="item.id"
+  [attr.data-status]="item.canDelete ? 'enabled' : 'disabled'">
+  Delete
+</button>
+
+<!-- Icon Button -->
+<button
+  (click)="toggleMenu()"
+  data-what="menu-button"
+  data-which="main-nav"
+  aria-label="Toggle menu">
+  <i class="icon-menu"></i>
+</button>
+
+<!-- Custom Button Component -->
+<ui-button
+  (click)="save()"
+  data-what="save-button"
+  data-which="order-form">
+  Save Order
+</ui-button>
+```
+
+### Inputs
+
+```html
+<!-- Text Input -->
+<input
+  type="text"
+  [(ngModel)]="email"
+  placeholder="Email address"
+  data-what="email-input"
+  data-which="registration-form" />
+
+<!-- Textarea -->
+<textarea
+  [(ngModel)]="comments"
+  data-what="comments-textarea"

+
+## Patterns by Component Type
+
+### Form Components
+
+```html
+<form data-what="user-form" data-which="registration">
+  <!-- Field inputs -->
+  <input
+    data-what="username-input"
+    data-which="registration-form"
+    type="text" />
+
+  <input
+    data-what="email-input"
+    data-which="registration-form"
+    type="email" />
+
+  <!-- Action buttons -->
+  <button
+    data-what="submit-button"
+    data-which="registration-form"
+    type="submit">
+    Submit
+  </button>
+
+  <button
+    data-what="cancel-button"
+    data-which="registration-form"
+    type="button">
+    Cancel
+  </button>
+</form>
+```
+
+### List/Table Components
+
+```html
+<!-- Each item needs unique data-which -->
+@for (item of items; track item.id) {
+  <div
+    data-what="list-item"
+    [attr.data-which]="item.id">
+
+    <span data-what="item-name" [attr.data-which]="item.id">
+      {{ item.name }}
+    </span>
+
+    <button
+      data-what="edit-button"
+      [attr.data-which]="item.id">
+      Edit
+    </button>
+
+    <button
+      data-what="delete-button"
+      [attr.data-which]="item.id">
+      Delete
+    </button>
+  </div>
+}
+```
+
+### Navigation Components
+
+```html
+<nav data-what="main-navigation" data-which="header">
+  <a
+    routerLink="/dashboard"
+    data-what="nav-link"
+    data-which="dashboard">
+    Dashboard
+  </a>
+
+  <a
+    routerLink="/orders"
+    data-what="nav-link"
+    data-which="orders">
+    Orders
+  </a>
+
+  <a
+    routerLink="/customers"
+    data-what="nav-link"
+    data-which="customers">
+    Customers
+  </a>
+</nav>
+
+<!-- Breadcrumbs -->
+<nav data-what="breadcrumb" data-which="page-navigation">
+  @for (crumb of breadcrumbs; track $index) {
+    <a
+      [routerLink]="crumb.url"
+      data-what="breadcrumb-link"
+      [attr.data-which]="crumb.id">
+      {{ crumb.label }}
+    </a>
+  }
+</nav>
+```
+
+### Dialog/Modal Components
+
+```html
+<!-- All dialog buttons need clear identifiers -->
+<div data-what="modal" data-which="user-settings">
+  <button
+    data-what="close-button"
+    data-which="modal">
+    Close
+  </button>
+
+  <button
+    data-what="save-button"
+    data-which="modal">
+    Save Changes
+  </button>
+
+  <button
+    data-what="reset-button"
+    data-which="modal">
+    Reset to Defaults
+  </button>
+</div>
+```
+
+## Dynamic Attributes
+
+### Using Angular Binding
+
+When values need to be dynamic, use Angular's attribute binding:
+
+```html
+<!-- Static (simple values) -->
+<button data-what="submit-button" data-which="form">
+
+<!-- Dynamic (from component properties) -->
+<button
+  data-what="submit-button"
+  [attr.data-which]="formId">
+
+<!-- Dynamic (from loop variables) -->
+@for (item of items; track item.id) {
+  <div
+    data-what="list-item"
+    [attr.data-which]="item.id"
+    [attr.data-status]="item.status"
+    [attr.data-index]="$index">
+  </div>
+}
+
+<!-- Dynamic (computed values) -->
+<button
+  data-what="action-button"
+  [attr.data-which]="'customer-' + customerId + '-' + action">
+</button>
+```
+
+### Loop Variables
+
+Angular's `@for` provides special variables:
+
+```html
+@for (item of items; track item.id; let idx = $index; let isFirst = $first) {
+  <div
+    data-what="list-item"
+    [attr.data-which]="item.id"
+    [attr.data-index]="idx"
+    [attr.data-first]="isFirst">
+    {{ item.name }}
+  </div>
+}
+```
+
+## Best Practices
+
+### Do's ✅
+
+1. **Add to ALL interactive elements**
+   - Buttons, inputs, links, clickable elements
+   - Custom components that handle user interaction
+   - Form controls and navigation items
+
+2. **Use consistent naming**
+   - Follow the naming patterns (e.g., `*-button`, `*-input`)
+   - Use kebab-case consistently
+   - Be descriptive but concise
+
+3. **Ensure uniqueness**
+   - `data-which` must be unique within the view
+   - Use item IDs for list items: `[attr.data-which]="item.id"`
+   - Combine context when needed: `data-which="form-primary-submit"`
+
+4. **Use Angular binding for dynamic values**
+   - `[attr.data-which]="item.id"` ✅
+   - `data-which="{{ item.id }}"` ❌ (avoid interpolation)
+
+5. **Document complex patterns**
+   - Add comments for non-obvious attribute choices
+   - Document the expected test selectors
+
+6. **Keep attributes updated**
+   - Update when element purpose changes
+   - Remove when elements are removed
+   - Maintain consistency across refactoring
+
+### Don'ts ❌
+
+1. **Don't include sensitive data**
+   - ❌ `data-which="password-{{ userPassword }}"`
+   - ❌ `data-token="{{ authToken }}"`
+   - ❌ `data-ssn="{{ socialSecurity }}"`
+
+2. **Don't use generic values**
+   - ❌ `data-what="button"` (too generic)
+   - ✅ `data-what="submit-button"` (specific)
+
+3. **Don't duplicate `data-which` in the same view**
+   - ❌ Two buttons with `data-which="primary"`
+   - ✅ `data-which="form-primary"` and `data-which="dialog-primary"`
+
+4. **Don't rely only on index for lists**
+   - ❌ `[attr.data-which]="$index"` (changes when list reorders)
+   - ✅ `[attr.data-which]="item.id"` (stable identifier)
+
+5. **Don't forget about custom components**
+   - Custom components need attributes too
+   - Attributes should be on the component tag, not just internal elements
+
+## Validation
+
+### Coverage Check
+
+Ensure all interactive elements have E2E attributes:
+
+```bash
+# Count interactive elements
+grep -E '\(click\)|routerLink|button|input|select|textarea' component.html | wc -l
+
+# Count elements with data-what
+grep -c 'data-what=' component.html
+
+# Find elements missing E2E attributes
+grep -E '\(click\)|button' component.html | grep -v 'data-what='
+```
+
+### Uniqueness Check
+
+Verify no duplicate `data-which` values in the same template:
+
+```typescript
+// In component tests
+it('should have unique data-which attributes', () => {
+  const elements = fixture.nativeElement.querySelectorAll('[data-which]');
+  const dataWhichValues = Array.from(elements).map(
+    (el: any) => el.getAttribute('data-which')
+  );
+
+  const uniqueValues = new Set(dataWhichValues);
+  expect(dataWhichValues.length).toBe(uniqueValues.size);
+});
+```
+
+### Validation Checklist
+
+- [ ] All buttons have `data-what` and `data-which`
+- [ ] All inputs have `data-what` and `data-which`
+- [ ] All links have `data-what` and `data-which`
+- [ ] All clickable elements have attributes

+- [ ] No duplicate `data-which` values in the same view
+- [ ] No sensitive data in attributes
+- [ ] Custom components have attributes
+- [ ] Attributes use kebab-case
+- [ ] Coverage: 100% of interactive elements
+
+## Testing Integration
+
+### Using E2E Attributes in Tests
+
+**Unit Tests (Angular Testing Utilities)**:
+```typescript
+import { ComponentFixture, TestBed } from '@angular/core/testing';
+
+describe('MyComponent', () => {
+  let fixture: ComponentFixture<MyComponent>;
+
+  beforeEach(async () => {
+    await TestBed.configureTestingModule({
+      imports: [MyComponent],
+    }).compileComponents();
+
+    fixture = TestBed.createComponent(MyComponent);
+    fixture.detectChanges();
+  });
+
+  it('should have submit button with E2E attributes', () => {
+    const button = fixture.nativeElement.querySelector(
+      '[data-what="submit-button"][data-which="registration-form"]'
+    );
+    expect(button).toBeTruthy();
+    expect(button.textContent).toContain('Submit');
+  });
+
+  it('should have unique data-which for list items', () => {
+    const items = fixture.nativeElement.querySelectorAll('[data-what="list-item"]');
+    const dataWhichValues = Array.from(items).map(
+      (item: any) => item.getAttribute('data-which')
+    );
+
+    // All should have unique IDs
+    const uniqueValues = new Set(dataWhichValues);
+    expect(dataWhichValues.length).toBe(uniqueValues.size);
+  });
+});
+```
+
+**E2E Tests (Playwright)**:
+```typescript
+import { test, expect } from '@playwright/test';
+
+test('user registration flow', async ({ page }) => {
+  await page.goto('/register');
+
+  // Fill form using E2E attributes
+  await page.fill(
+    '[data-what="username-input"][data-which="registration-form"]',
+    'johndoe'
+  );
+
+  await page.fill(
+    '[data-what="email-input"][data-which="registration-form"]',
+    'john@example.com'
+  );
+
+  // Click submit using E2E attributes
+  await page.click(
+    '[data-what="submit-button"][data-which="registration-form"]'
+  );
+
+  // Verify success
+  await expect(page.locator('[data-what="success-message"]')).toBeVisible();
+});
+```
+
+**E2E Tests (Cypress)**:
+```typescript
+describe('Order Management', () => {
+  it('should edit an order', () => {
+    cy.visit('/orders');
+
+    // Find specific order by ID using data-which
+    cy.get('[data-what="list-item"][data-which="order-123"]')
+      .should('be.visible');
+
+    // Click edit button for that specific order
+    cy.get('[data-what="edit-button"][data-which="order-123"]')
+      .click();
+
+    // Update quantity
+    cy.get('[data-what="quantity-input"][data-which="order-form"]')
+      .clear()
+      .type('5');
+
+    // Save changes
+    cy.get('[data-what="save-button"][data-which="order-form"]')
+      .click();
+  });
+});
+```
+
+## Documentation in Templates
+
+Add comment blocks to document E2E attributes:
+
+```html
+<!--
+E2E Test Attributes:
+- data-what="submit-button" data-which="registration-form" - Main form submission
+- data-what="cancel-button" data-which="registration-form" - Cancel registration
+- data-what="username-input" data-which="registration-form" - Username field
+- data-what="email-input" data-which="registration-form" - Email field
+- data-what="password-input" data-which="registration-form" - Password field
+-->
+
+<form data-what="registration-form" data-which="user-signup">
+  <!-- Form content -->
+</form>
+```

+name: library-scaffolder
+description: This skill should be used when creating new Angular libraries in the ISA-Frontend monorepo. It handles Nx library generation with proper naming conventions, Vitest configuration with JUnit/Cobertura reporters, path alias setup, and validation. Use this skill when the user wants to create a new library, scaffold a feature/data-access/ui/util library, or requests "new library" creation.
+---
+
+# Library Scaffolder
+
+## Overview
+
+Automate the creation of new Angular libraries following ISA-Frontend conventions. This skill handles the complete scaffolding workflow including Nx generation, Vitest configuration with CI/CD integration, path alias verification, and initial validation.
+
+## When to Use This Skill
+
+Invoke this skill when:
+- User requests creating a new library
+- User mentions "new library", "scaffold library", or "create feature"
+- User wants to add a new domain/layer/feature to the monorepo
+
+## Required Parameters
+
+User must provide:
+- **domain**: Domain name (oms, remission, checkout, ui, core, shared, utils)
+- **layer**: Layer type (feature, data-access, ui, util)
+- **name**: Library name in kebab-case
+
+## Scaffolding Workflow
+
+### Step 1: Validate Input
+
+1. **Verify Domain**
+   - Use `docs-researcher` to check `docs/library-reference.md`
+   - Ensure domain follows existing patterns
+
+2. **Validate Layer**
+   - Must be one of: feature, data-access, ui, util
+
+3. **Check Name**
+   - Must be kebab-case
+   - Must not conflict with existing libraries
+
+4. **Determine Path Depth**
+   - 3 levels: `libs/domain/layer/name` → `../../../`
+   - 4 levels: `libs/domain/type/layer/name` → `../../../../`
+
+### Step 2: Run Dry-Run
+
+Execute Nx generator with `--dry-run`:
+
+```bash
+npx nx generate @nx/angular:library \
+  --name=[domain]-[layer]-[name] \
+  --directory=libs/[domain]/[layer]/[name] \
+  --importPath=@isa/[domain]/[layer]/[name] \
+  --style=css \
+  --unitTestRunner=vitest \
+  --standalone=true \
+  --skipTests=false \
+  --dry-run
+```
+
+Review output with user before proceeding.
+
+### Step 3: Generate Library
+
+Execute without `--dry-run`:
+
+```bash
+npx nx generate @nx/angular:library \
+  --name=[domain]-[layer]-[name] \
+  --directory=libs/[domain]/[layer]/[name] \
+  --importPath=@isa/[domain]/[layer]/[name] \
+  --style=css \
+  --unitTestRunner=vitest \
+  --standalone=true \
+  --skipTests=false
+```
+
+### Step 4: Configure Vitest with JUnit and Cobertura
+
+Update `libs/[path]/vite.config.mts`:
+
+```typescript
+/// <reference types='vitest' />
+import { defineConfig } from 'vite';
+import angular from '@analogjs/vite-plugin-angular';
+import { nxViteTsPaths } from '@nx/vite/plugins/nx-tsconfig-paths.plugin';
+import { nxCopyAssetsPlugin } from '@nx/vite/plugins/nx-copy-assets.plugin';
+
+export default
+// @ts-expect-error - Vitest reporter tuple types have complex inference issues
+defineConfig(() => ({
+  root: __dirname,
+  cacheDir: '../../../node_modules/.vite/libs/[path]',
+  plugins: [angular(), nxViteTsPaths(), nxCopyAssetsPlugin(['*.md'])],
+  test: {
+    watch: false,
+    globals: true,
+    environment: 'jsdom',
+    include: ['{src,tests}/**/*.{test,spec}.{js,mjs,cjs,ts,mts,cts,jsx,tsx}'],
+    setupFiles: ['src/test-setup.ts'],
+    reporters: [
+      'default',
+      ['junit', { outputFile: '../../../testresults/junit-[library-name].xml' }],
+    ],
+    coverage: {
+      reportsDirectory: '../../../coverage/libs/[path]',
+      provider: 'v8' as const,
+      reporter: ['text', 'cobertura'],
+    },
+  },
+}));
+```
+
+**Critical**: Adjust path depth based on library location.
+
+### Step 5: Verify Configuration
+
+1. **Check Path Alias**
+   - Verify `tsconfig.base.json` was updated
+   - Should have: `"@isa/[domain]/[layer]/[name]": ["libs/[domain]/[layer]/[name]/src/index.ts"]`
+
+2. **Run Initial Test**
+   ```bash
+   npx nx test [library-name] --coverage.enabled=true --skip-nx-cache
+   ```
+
+3. **Verify CI/CD Files Created**
+   - JUnit XML: `testresults/junit-[library-name].xml`
+   - Cobertura XML: `coverage/libs/[path]/cobertura-coverage.xml`
+
+### Step 6: Create Library README
+
+Use `docs-researcher` to find similar library READMEs, then create comprehensive documentation including:
+- Overview and purpose
+- Installation/import instructions
+- API documentation
+- Usage examples
+- Testing information (Vitest + Angular Testing Utilities)
+
+### Step 7: Update Library Reference
+
+Add entry to `docs/library-reference.md` under appropriate domain:
+
+```markdown
+#### `@isa/[domain]/[layer]/[name]`
+**Path:** `libs/[domain]/[layer]/[name]`
+**Type:** [Feature/Data Access/UI/Util]
+**Testing:** Vitest
+
+[Brief description]
+```
+
+### Step 8: Run Full Validation
+
+```bash
+# Lint
+npx nx lint [library-name]
+
+# Test with coverage
+npx nx test [library-name] --coverage.enabled=true --skip-nx-cache
+
+# Build (if buildable)
+npx nx build [library-name]
+
+# Dependency graph
+npx nx graph --focus=[library-name]
+```
+
+### Step 9: Generate Creation Report
+
+```

+
+## Error Handling
+
+**Issue: Path depth mismatch**
+- Count directory levels from workspace root
+- Adjust `../` in outputFile and reportsDirectory
+
+**Issue: TypeScript errors in vite.config.mts**
+- Add `// @ts-expect-error` before `defineConfig()`
+
+**Issue: Path alias not working**

+name: logging-helper
+description: This skill should be used when working with Angular components, directives, services, pipes, guards, or TypeScript classes. Logging is MANDATORY in all Angular files. Implements @isa/core/logging with logger() factory pattern, appropriate log levels, lazy evaluation for performance, error handling, and avoids console.log and common mistakes.
+---
+
+# Logging Helper Skill
+
+Ensures consistent and efficient logging using `@isa/core/logging` library.
+
+## When to Use
+
+- Adding logging to new components/services
+- Refactoring existing logging code
+- Reviewing code for proper logging patterns
+- Debugging logging issues
+
+## Core Principles
+
+### 1. Always Use Factory Pattern
+
+```typescript
+import { logger } from '@isa/core/logging';
+
+// ✅ DO
+#logger = logger();
+
+// ❌ DON'T
+constructor(private loggingService: LoggingService) {}
+```
+
+### 2. Choose Appropriate Log Levels
+
+- **Trace**: Fine-grained debugging (method entry/exit)
+- **Debug**: Development debugging (variable states)
+- **Info**: Runtime information (user actions, events)
+- **Warn**: Potentially harmful situations
+- **Error**: Errors affecting functionality
+
+### 3. Context Patterns
+
+**Static Context** (component level):
+```typescript
+#logger = logger({ component: 'UserProfileComponent' });
+```
+
+**Dynamic Context** (instance level):
+```typescript
+#logger = logger(() => ({
+  userId: this.authService.currentUserId,
+  storeId: this.config.storeId
+}));
+```
+
+**Message Context** (use functions for performance):
+```typescript
+// ✅ Recommended - lazy evaluation
+this.#logger.info('Order processed', () => ({
+  orderId: order.id,
+  total: order.total,
+  timestamp: Date.now()
+}));
+
+// ✅ Acceptable - static values
+this.#logger.info('Order processed', {
+  orderId: order.id,
+  status: 'completed'
+});
+```
+
+## Essential Patterns
+
+### Component Logging
+```typescript
+@Component({
+  selector: 'app-product-list',
+  standalone: true,
+})
+export class ProductListComponent {
+  #logger = logger({ component: 'ProductListComponent' });
+
+  ngOnInit(): void {
+    this.#logger.info('Component initialized');
+  }
+
+  onAction(id: string): void {
+    this.#logger.debug('Action triggered', { id });
+  }
+}
+```
+
+### Service Logging
+```typescript
+@Injectable({ providedIn: 'root' })
+export class DataService {
+  #logger = logger({ service: 'DataService' });
+
+  fetchData(endpoint: string): Observable<Data> {
+    this.#logger.debug('Fetching data', { endpoint });
+
+    return this.http.get<Data>(endpoint).pipe(
+      tap((data) => this.#logger.info('Data fetched', () => ({
+        endpoint,
+        size: data.length
+      }))),
+      catchError((error) => {
+        this.#logger.error('Fetch failed', error, () => ({
+          endpoint,
+          status: error.status
+        }));
+        return throwError(() => error);
+      })
+    );
+  }
+}
+```
+
+### Error Handling
+```typescript
+try {
+  await this.processOrder(orderId);
+} catch (error) {
+  this.#logger.error('Order processing failed', error as Error, () => ({
+    orderId,
+    step: this.currentStep,
+    attemptNumber: this.retryCount
+  }));
+  throw error;
+}
+```
+
+### Hierarchical Context
+```typescript
+@Component({
+  providers: [
+    provideLoggerContext({ feature: 'checkout', module: 'sales' })
+  ]
+})
+export class CheckoutComponent {
+  #logger = logger(() => ({ userId: this.userService.currentUserId }));
+
+  // Logs include: feature, module, userId + message context
+}
+```
+
+## Common Mistakes to Avoid
+
+```typescript
+// ❌ Don't use console.log
+console.log('User logged in');
+// ✅ Use logger
+this.#logger.info('User logged in');
+
+// ❌ Don't create expensive context eagerly
+this.#logger.debug('Processing', {
+  data: this.computeExpensive() // Always executes
+});
+// ✅ Use function for lazy evaluation
+this.#logger.debug('Processing', () => ({
+  data: this.computeExpensive() // Only if debug enabled
+}));
+
+// ❌ Don't log in tight loops
+for (const item of items) {
+  this.#logger.debug('Item', { item });
+}
+// ✅ Log aggregates
+this.#logger.debug('Batch processed', () => ({
+  count: items.length
+}));
+
+// ❌ Don't log sensitive data
+this.#logger.info('User auth', { password: user.password });
+// ✅ Log safe identifiers only
+this.#logger.info('User auth', { userId: user.id });
+
+// ❌ Don't miss error object
+this.#logger.error('Failed');
+// ✅ Include error object
+this.#logger.error('Failed', error as Error);
+```
+
+## Configuration
+
+### App Configuration
+```typescript
+// app.config.ts
+import { ApplicationConfig, isDevMode } from '@angular/core';
+import {
+  provideLogging, withLogLevel, withSink,
+  LogLevel, ConsoleLogSink
+} from '@isa/core/logging';
+
+export const appConfig: ApplicationConfig = {
+  providers: [
+    provideLogging(
+      withLogLevel(isDevMode() ? LogLevel.Debug : LogLevel.Warn),
+      withSink(ConsoleLogSink),
+      withContext({ app: 'ISA', version: '1.0.0' })
+    )
+  ]
+};
+```
+
+## Testing
+
+```typescript
+import { createComponentFactory, Spectator } from '@ngneat/spectator/jest';
+import { LoggingService } from '@isa/core/logging';
+
+describe('MyComponent', () => {
+  const createComponent = createComponentFactory({
+    component: MyComponent,
+    mocks: [LoggingService]
+  });
+
+  it('should log error', () => {
+    const spectator = createComponent();
+    const loggingService = spectator.inject(LoggingService);
+
+    spectator.component.riskyOperation();
+
+    expect(loggingService.error).toHaveBeenCalledWith(
+      expect.any(String),
+      expect.any(Error),
+      expect.any(Function)
+    );
+  });
+});
+```
+
+## Code Review Checklist
+
+- [ ] Uses `logger()` factory, not `LoggingService` injection
+- [ ] Appropriate log level for each message
+- [ ] Context functions for expensive operations
+- [ ] No sensitive information (passwords, tokens, PII)
+- [ ] No `console.log` statements
+- [ ] Error logs include error object
+- [ ] No logging in tight loops
+- [ ] Component/service identified in context
+- [ ] E2E attributes on interactive elements
+

+# Logging Examples
+
+Concise real-world examples of logging patterns.
+
+## 1. Component with Observable
+
+```typescript
+import { Component, OnInit } from '@angular/core';
+import { logger } from '@isa/core/logging';
+
+@Component({
+  selector: 'app-product-list',
+  standalone: true,
+})
+export class ProductListComponent implements OnInit {
+  #logger = logger({ component: 'ProductListComponent' });
+
+  constructor(private productService: ProductService) {}
+
+  ngOnInit(): void {
+    this.#logger.info('Component initialized');
+    this.loadProducts();
+  }
+
+  private loadProducts(): void {
+    this.productService.getProducts().subscribe({
+      next: (products) => {
+        this.#logger.info('Products loaded', () => ({ count: products.length }));
+      },
+      error: (error) => {
+        this.#logger.error('Failed to load products', error);
+      }
+    });
+  }
+}
+```
+
+## 2. Service with HTTP
+
+```typescript
+import { Injectable, inject } from '@angular/core';
+import { HttpClient } from '@angular/common/http';
+import { logger } from '@isa/core/logging';
+import { catchError, tap } from 'rxjs/operators';
+
+@Injectable({ providedIn: 'root' })
+export class OrderService {
+  private http = inject(HttpClient);
+  #logger = logger({ service: 'OrderService' });
+
+  getOrder(id: string): Observable<Order> {
+    this.#logger.debug('Fetching order', { id });
+
+    return this.http.get<Order>(`/api/orders/${id}`).pipe(
+      tap((order) => this.#logger.info('Order fetched', () => ({
+        id,
+        status: order.status
+      }))),
+      catchError((error) => {
+        this.#logger.error('Fetch failed', error, () => ({ id, status: error.status }));
+        throw error;
+      })
+    );
+  }
+}
+```
+
+## 3. Hierarchical Context
+
+```typescript
+import { Component } from '@angular/core';
+import { logger, provideLoggerContext } from '@isa/core/logging';
+
+@Component({
+  selector: 'oms-return-process',
+  standalone: true,
+  providers: [
+    provideLoggerContext({ feature: 'returns', module: 'oms' })
+  ],
+})
+export class ReturnProcessComponent {
+  #logger = logger(() => ({
+    processId: this.currentProcessId,
+    step: this.currentStep
+  }));
+
+  private currentProcessId = crypto.randomUUID();
+  private currentStep = 1;
+
+  startProcess(orderId: string): void {
+    // Logs include: feature, module, processId, step, orderId
+    this.#logger.info('Process started', { orderId });
+  }
+}
+```
+
+## 4. NgRx Effect
+
+```typescript
+import { Injectable } from '@angular/core';
+import { Actions, createEffect, ofType } from '@ngrx/effects';
+import { logger } from '@isa/core/logging';
+import { map, catchError, tap } from 'rxjs/operators';
+import { of } from 'rxjs';
+
+@Injectable()
+export class OrdersEffects {
+  #logger = logger({ effect: 'OrdersEffects' });
+
+  loadOrders$ = createEffect(() =>
+    this.actions$.pipe(
+      ofType(OrdersActions.loadOrders),
+      tap((action) => this.#logger.debug('Loading orders', () => ({
+        page: action.page
+      }))),
+      mergeMap((action) =>
+        this.orderService.getOrders(action.filters).pipe(
+          map((orders) => {
+            this.#logger.info('Orders loaded', () => ({ count: orders.length }));
+            return OrdersActions.loadOrdersSuccess({ orders });
+          }),
+          catchError((error) => {
+            this.#logger.error('Load failed', error);
+            return of(OrdersActions.loadOrdersFailure({ error }));
+          })
+        )
+      )
+    )
+  );
+
+  constructor(
+    private actions$: Actions,
+    private orderService: OrderService
+  ) {}
+}
+```
+
+## 5. Guard with Authorization
+
+```typescript
+import { inject } from '@angular/core';
+import { CanActivateFn, Router } from '@angular/router';
+import { logger } from '@isa/core/logging';
+
+export const authGuard: CanActivateFn = (route, state) => {
+  const authService = inject(AuthService);
+  const router = inject(Router);
+  const log = logger({ guard: 'AuthGuard' });
+
+  if (authService.isAuthenticated()) {
+    log.debug('Access granted', () => ({ route: state.url }));
+    return true;
+  }
+
+  log.warn('Access denied', () => ({
+    attemptedRoute: state.url,
+    redirectTo: '/login'
+  }));
+  return router.createUrlTree(['/login']);
+};
+```
+
+## 6. HTTP Interceptor
+
+```typescript
+import { HttpInterceptorFn } from '@angular/common/http';
+import { inject } from '@angular/core';
+import { tap, catchError } from 'rxjs/operators';
+import { LoggingService } from '@isa/core/logging';
+
+export const loggingInterceptor: HttpInterceptorFn = (req, next) => {
+  const loggingService = inject(LoggingService);
+  const startTime = performance.now();
+
+  loggingService.debug('HTTP Request', () => ({
+    method: req.method,
+    url: req.url
+  }));
+
+  return next(req).pipe(
+    tap((event) => {
+      if (event.type === HttpEventType.Response) {
+        loggingService.info('HTTP Response', () => ({
+          method: req.method,
+          url: req.url,
+          status: event.status,
+          duration: `${(performance.now() - startTime).toFixed(2)}ms`
+        }));
+      }
+    }),
+    catchError((error) => {
+      loggingService.error('HTTP Error', error, () => ({
+        method: req.method,
+        url: req.url,
+        status: error.status
+      }));
+      return throwError(() => error);
+    })
+  );
+};
+```
+
+## 7. Form Validation
+
+```typescript
+import { Component, OnInit } from '@angular/core';
+import { FormBuilder, FormGroup, Validators } from '@angular/forms';
+import { logger } from '@isa/core/logging';
+
+@Component({
+  selector: 'shared-user-form',
+  standalone: true,
+})
+export class UserFormComponent implements OnInit {
+  #logger = logger({ component: 'UserFormComponent' });
+  form!: FormGroup;
+
+  constructor(private fb: FormBuilder) {}
+
+  ngOnInit(): void {
+    this.form = this.fb.group({
+      name: ['', Validators.required],
+      email: ['', [Validators.required, Validators.email]]
+    });
+  }
+
+  onSubmit(): void {
+    if (this.form.invalid) {
+      this.#logger.warn('Invalid form submission', () => ({
+        errors: this.getFormErrors()
+      }));
+      return;
+    }
+
+    this.#logger.info('Form submitted');
+  }
+
+  private getFormErrors(): Record<string, unknown> {
+    const errors: Record<string, unknown> = {};
+    Object.keys(this.form.controls).forEach((key) => {
+      const control = this.form.get(key);
+      if (control?.errors) errors[key] = control.errors;
+    });
+    return errors;
+  }
+}
+```
+
+## 8. Async Progress Tracking
+
+```typescript
+import { Injectable } from '@angular/core';
+import { logger } from '@isa/core/logging';
+import { Observable } from 'rxjs';
+import { tap } from 'rxjs/operators';
+
+@Injectable({ providedIn: 'root' })
+export class ImportService {
+  #logger = logger({ service: 'ImportService' });
+
+  importData(file: File): Observable<number> {
+    const importId = crypto.randomUUID();
+
+    this.#logger.info('Import started', () => ({
+      importId,
+      fileName: file.name,
+      fileSize: file.size
+    }));
+
+    return this.processImport(file).pipe(
+      tap((progress) => {
+        if (progress % 25 === 0) {
+          this.#logger.debug('Import progress', () => ({
+            importId,
+            progress: `${progress}%`
+          }));
+        }
+      }),
+      tap({
+        complete: () => this.#logger.info('Import completed', { importId }),
+        error: (error) => this.#logger.error('Import failed', error, { importId })
+      })
+    );
+  }
+
+  private processImport(file: File): Observable<number> {
+    // Implementation
+  }
+}
+```
+
+## 9. Global Error Handler
+
+```typescript
+import { Injectable, ErrorHandler } from '@angular/core';
+import { logger } from '@isa/core/logging';
+
+@Injectable()
+export class GlobalErrorHandler implements ErrorHandler {
+  #logger = logger({ handler: 'GlobalErrorHandler' });
+
+  handleError(error: Error): void {
+    this.#logger.error('Uncaught error', error, () => ({
+      url: window.location.href,
+      userAgent: navigator.userAgent,
+      timestamp: new Date().toISOString()
+    }));
+  }
+}
+```
+
+## 10. WebSocket Component
+
+```typescript
+import { Component, OnInit, OnDestroy } from '@angular/core';
+import { logger } from '@isa/core/logging';
+import { Subject, takeUntil } from 'rxjs';
+
+@Component({
+  selector: 'oms-live-orders',
+  standalone: true,
+})
+export class LiveOrdersComponent implements OnInit, OnDestroy {
+  #logger = logger({ component: 'LiveOrdersComponent' });
+  private destroy$ = new Subject<void>();
+
+  constructor(private wsService: WebSocketService) {}
+
+  ngOnInit(): void {
+    this.#logger.info('Connecting to WebSocket');
+
+    this.wsService.connect('orders').pipe(
+      takeUntil(this.destroy$)
+    ).subscribe({
+      next: (msg) => this.#logger.debug('Message received', () => ({
+        type: msg.type,
+        orderId: msg.orderId
+      })),
+      error: (error) => this.#logger.error('WebSocket error', error),
+      complete: () => this.#logger.info('WebSocket closed')
+    });
+  }
+
+  ngOnDestroy(): void {
+    this.#logger.debug('Component destroyed');
+    this.destroy$.next();
+    this.destroy$.complete();
+  }

+## API Signatures
+
+```typescript
+// Factory
+function logger(ctx?: MaybeLoggerContextFn): LoggerApi
+
+// Logger API
+interface LoggerApi {
+  trace(message: string, context?: MaybeLoggerContextFn): void;
+  debug(message: string, context?: MaybeLoggerContextFn): void;
+  info(message: string, context?: MaybeLoggerContextFn): void;
+  warn(message: string, context?: MaybeLoggerContextFn): void;

+}
+
+// Types
+type MaybeLoggerContextFn = LoggerContext | (() => LoggerContext);
+interface LoggerContext { [key: string]: unknown; }
+```
+
+## Common Patterns
+
+| Pattern | Code |
+|---------|------|
+| Basic logger | `#logger = logger()` |
+| Static context | `#logger = logger({ component: 'Name' })` |
+| Dynamic context | `#logger = logger(() => ({ id: this.id }))` |
+| Log info | `this.#logger.info('Message')` |
+| Log with context | `this.#logger.info('Message', () => ({ key: value }))` |
+| Log error | `this.#logger.error('Error', error)` |
+| Error with context | `this.#logger.error('Error', error, () => ({ id }))` |
+| Component context | `providers: [provideLoggerContext({ feature: 'x' })]` |
+
+## Configuration
+
+```typescript
+// app.config.ts
+import { provideLogging, withLogLevel, withSink, withContext,
+         LogLevel, ConsoleLogSink } from '@isa/core/logging';
+
+export const appConfig: ApplicationConfig = {
+  providers: [
+    provideLogging(
+      withLogLevel(isDevMode() ? LogLevel.Debug : LogLevel.Warn),
+      withSink(ConsoleLogSink),
+      withContext({ app: 'ISA', version: '1.0.0' })
+    )
+  ]
+};
+```
+
+## Log Levels
+
+| Level | Use Case | Example |
+|-------|----------|---------|
+| `Trace` | Method entry/exit | `this.#logger.trace('Entering processData')` |
+| `Debug` | Development info | `this.#logger.debug('Variable state', () => ({ x }))` |
+| `Info` | Runtime events | `this.#logger.info('User logged in', { userId })` |
+| `Warn` | Warnings | `this.#logger.warn('Deprecated API used')` |
+| `Error` | Errors | `this.#logger.error('Operation failed', error)` |
+| `Off` | Disable logging | `withLogLevel(LogLevel.Off)` |
+
+## Decision Trees
+
+### Context Type Decision
+```
+Value changes at runtime?
+├─ Yes → () => ({ value: this.getValue() })
+└─ No  → { value: 'static' }
+
+Computing value is expensive?
+├─ Yes → () => ({ data: this.compute() })
+└─ No  → Either works
+```
+
+### Log Level Decision
+```
+Method flow details? → Trace
+Development debug?  → Debug
+Runtime information? → Info
+Potential problem?  → Warn
+Error occurred?     → Error
+```
+
+## Performance Tips
+
+```typescript
+// ✅ DO: Lazy evaluation
+this.#logger.debug('Data', () => ({
+  result: this.expensive() // Only runs if debug enabled
+}));
+
+// ❌ DON'T: Eager evaluation
+this.#logger.debug('Data', {
+  result: this.expensive() // Always runs
+});
+
+// ✅ DO: Log aggregates
+this.#logger.info('Batch done', () => ({ count: items.length }));
+
+// ❌ DON'T: Log in loops
+for (const item of items) {
+  this.#logger.debug('Item', { item }); // Performance hit
+}
+```
+
+## Testing
+
+```typescript
+import { createComponentFactory, Spectator } from '@ngneat/spectator/jest';
+import { LoggingService } from '@isa/core/logging';
+
+describe('MyComponent', () => {
+  const createComponent = createComponentFactory({
+    component: MyComponent,
+    mocks: [LoggingService]
+  });
+
+  it('logs error', () => {
+    const spectator = createComponent();
+    const logger = spectator.inject(LoggingService);
+
+    spectator.component.operation();
+
+    expect(logger.error).toHaveBeenCalled();
+  });
+});
+```
+
+## Custom Sink
+
+```typescript
+import { Injectable } from '@angular/core';
+import { Sink, LogLevel, LoggerContext } from '@isa/core/logging';
+
+@Injectable()
+export class CustomSink implements Sink {
+  log(level: LogLevel, message: string, context?: LoggerContext, error?: Error): void {
+    // Implementation
+  }
+}
+
+// Register
+provideLogging(withSink(CustomSink))
+```
+
+## Sink Function (with DI)
+
+```typescript
+import { inject } from '@angular/core';
+import { SinkFn, LogLevel } from '@isa/core/logging';
+
+export const remoteSink: SinkFn = () => {

+# Logging Troubleshooting
+
+## 1. Logs Not Appearing
+
+**Problem:** Logger called but nothing in console.
+
+**Solutions:**
+```typescript
+// Check log level
+provideLogging(
+  withLogLevel(isDevMode() ? LogLevel.Debug : LogLevel.Warn)
+)
+
+// Add sink
+provideLogging(
+  withLogLevel(LogLevel.Debug),
+  withSink(ConsoleLogSink) // Required!
+)
+
+// Verify configuration in app.config.ts
+export const appConfig: ApplicationConfig = {
+  providers: [
+    provideLogging(...) // Must be present
+  ]
+};
+```
+
+## 2. NullInjectorError
+
+**Error:** `NullInjectorError: No provider for LoggingService!`
+
+**Solution:**
+```typescript
+// app.config.ts
+import { provideLogging, withLogLevel, withSink,
+         LogLevel, ConsoleLogSink } from '@isa/core/logging';
+
+export const appConfig: ApplicationConfig = {
+  providers: [
+    provideLogging(
+      withLogLevel(LogLevel.Debug),
+      withSink(ConsoleLogSink)
+    )
+  ]
+};
+```
+
+## 3. Context Not Showing
+
+**Problem:** Context passed but doesn't appear.
+
+**Check:**
+```typescript
+// ✅ Both work:
+this.#logger.info('Message', () => ({ id: '123' })); // Function
+this.#logger.info('Message', { id: '123' });          // Object
+
+// ❌ Common mistake:
+const ctx = { id: '123' };
+this.#logger.info('Message', ctx); // Actually works!
+
+// Verify hierarchical merge:
+// Global → Component → Instance → Message
+```
+
+## 4. Performance Issues
+
+**Problem:** Slow when debug logging enabled.
+
+**Solutions:**
+```typescript
+// ✅ Use lazy evaluation
+this.#logger.debug('Data', () => ({
+  expensive: this.compute() // Only if debug enabled
+}));
+
+// ✅ Reduce log frequency
+this.#logger.debug('Batch', () => ({
+  count: items.length // Not each item
+}));
+
+// ✅ Increase production level
+provideLogging(
+  withLogLevel(isDevMode() ? LogLevel.Debug : LogLevel.Warn)
+)
+```
+
+## 5. Error Object Not Logged
+
+**Problem:** Error shows as `[object Object]`.
+
+**Solution:**
+```typescript
+// ❌ Wrong
+this.#logger.error('Failed', { error }); // Don't wrap in object
+
+// ✅ Correct
+this.#logger.error('Failed', error as Error, () => ({
+  additionalContext: 'value'
+}));
+```
+
+## 6. TypeScript Errors
+
+**Error:** `Type 'X' is not assignable to 'MaybeLoggerContextFn'`
+
+**Solution:**
+```typescript
+// ❌ Wrong type
+this.#logger.info('Message', 'string'); // Invalid
+
+// ✅ Correct types
+this.#logger.info('Message', { key: 'value' });
+this.#logger.info('Message', () => ({ key: 'value' }));
+```
+
+## 7. Logs in Tests
+
+**Problem:** Test output cluttered with logs.
+
+**Solutions:**
+```typescript
+// Mock logging service
+import { createComponentFactory, Spectator } from '@ngneat/spectator/jest';
+import { LoggingService } from '@isa/core/logging';
+
+const createComponent = createComponentFactory({
+  component: MyComponent,
+  mocks: [LoggingService] // Mocks all log methods
+});
+
+// Or disable in tests
+TestBed.configureTestingModule({
+  providers: [
+    provideLogging(withLogLevel(LogLevel.Off))
+  ]
+});
+```
+
+## 8. Undefined Property Error
+
+**Error:** `Cannot read property 'X' of undefined`
+
+**Problem:** Accessing uninitialized property in logger context.
+
+**Solutions:**
+```typescript
+// ❌ Problem
+#logger = logger(() => ({
+  userId: this.userService.currentUserId // May be undefined
+}));
+
+// ✅ Solution 1: Optional chaining
+#logger = logger(() => ({
+  userId: this.userService?.currentUserId ?? 'unknown'
+}));
+
+// ✅ Solution 2: Delay access
+ngOnInit() {
+  this.#logger.info('Init', () => ({
+    userId: this.userService.currentUserId // Safe here
+  }));
+}
+```
+
+## 9. Circular Dependency
+
+**Error:** `NG0200: Circular dependency in DI detected`
+
+**Cause:** Service A ← → Service B both inject LoggingService.
+
+**Solution:**
+```typescript
+// ❌ Creates circular dependency
+constructor(private loggingService: LoggingService) {}
+
+// ✅ Use factory (no circular dependency)
+#logger = logger({ service: 'MyService' });
+```
+
+## 10. Custom Sink Not Working
+
+**Problem:** Sink registered but never called.
+
+**Solutions:**
+```typescript
+// ✅ Correct registration
+provideLogging(
+  withSink(MySink) // Add to config
+)
+
+// ✅ Correct signature
+export class MySink implements Sink {
+  log(
+    level: LogLevel,
+    message: string,
+    context?: LoggerContext,
+    error?: Error
+  ): void {
+    // Implementation
+  }
+}
+
+// ✅ Sink function must return function
+export const mySinkFn: SinkFn = () => {
+  const http = inject(HttpClient);
+  return (level, message, context, error) => {
+    // Implementation
+  };
+};
+```
+
+## Quick Diagnostics
+
+```typescript
+// Enable all logs temporarily
+provideLogging(withLogLevel(LogLevel.Trace))
+
+// Check imports
+import { logger } from '@isa/core/logging'; // ✅ Correct
+import { logger } from '@isa/core/logging/src/lib/logger.factory'; // ❌ Wrong
+
+// Verify console filters in browser DevTools
+// Ensure Info, Debug, Warnings are enabled
+```
+
+## Common Error Messages
+
+| Error | Cause | Fix |
+|-------|-------|-----|
+| `NullInjectorError: LoggingService` | Missing config | Add `provideLogging()` |
+| `Type 'X' not assignable` | Wrong context type | Use object or function |
+| `Cannot read property 'X'` | Undefined property | Use optional chaining |
+| `Circular dependency` | Service injection | Use `logger()` factory |
+| Stack overflow | Infinite loop in context | Don't call logger in context |

+# Skill Creator
+
+This skill provides guidance for creating effective skills.
+
+## About Skills
+
+Skills are modular, self-contained packages that extend Claude's capabilities by providing
+specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific
+domains or tasks—they transform Claude from a general-purpose agent into a specialized agent
+equipped with procedural knowledge that no model can fully possess.
+
+### What Skills Provide
+
+1. Specialized workflows - Multi-step procedures for specific domains
+2. Tool integrations - Instructions for working with specific file formats or APIs
+3. Domain expertise - Company-specific knowledge, schemas, business logic
+4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks
+
+### Anatomy of a Skill
+
+Every skill consists of a required SKILL.md file and optional bundled resources:
+
+```
+skill-name/
+├── SKILL.md (required)
+│   ├── YAML frontmatter metadata (required)
+│   │   ├── name: (required)
+│   │   └── description: (required)
+│   └── Markdown instructions (required)
+└── Bundled Resources (optional)
+    ├── scripts/          - Executable code (Python/Bash/etc.)
+    ├── references/       - Documentation intended to be loaded into context as needed
+    └── assets/           - Files used in output (templates, icons, fonts, etc.)
+```
+
+#### SKILL.md (required)
+
+**Metadata Quality:** The `name` and `description` in YAML frontmatter determine when Claude will use the skill. Be specific about what the skill does and when to use it. Use the third-person (e.g. "This skill should be used when..." instead of "Use this skill when...").
+
+#### Bundled Resources (optional)
+
+##### Scripts (`scripts/`)
+
+Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.
+
+- **When to include**: When the same code is being rewritten repeatedly or deterministic reliability is needed
+- **Example**: `scripts/rotate_pdf.py` for PDF rotation tasks
+- **Benefits**: Token efficient, deterministic, may be executed without loading into context
+- **Note**: Scripts may still need to be read by Claude for patching or environment-specific adjustments
+
+##### References (`references/`)
+
+Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking.
+
+- **When to include**: For documentation that Claude should reference while working
+- **Examples**: `references/finance.md` for financial schemas, `references/mnda.md` for company NDA template, `references/policies.md` for company policies, `references/api_docs.md` for API specifications
+- **Use cases**: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides
+- **Benefits**: Keeps SKILL.md lean, loaded only when Claude determines it's needed
+- **Best practice**: If files are large (>10k words), include grep search patterns in SKILL.md
+- **Avoid duplication**: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.
+
+##### Assets (`assets/`)
+
+Files not intended to be loaded into context, but rather used within the output Claude produces.
+
+- **When to include**: When the skill needs files that will be used in the final output
+- **Examples**: `assets/logo.png` for brand assets, `assets/slides.pptx` for PowerPoint templates, `assets/frontend-template/` for HTML/React boilerplate, `assets/font.ttf` for typography
+- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified
+- **Benefits**: Separates output resources from documentation, enables Claude to use files without loading them into context
+
+### Progressive Disclosure Design Principle
+
+Skills use a three-level loading system to manage context efficiently:
+
+1. **Metadata (name + description)** - Always in context (~100 words)
+2. **SKILL.md body** - When skill triggers (<5k words)
+3. **Bundled resources** - As needed by Claude (Unlimited*)
+
+*Unlimited because scripts can be executed without reading into context window.
+
+## Skill Creation Process
+
+To create a skill, follow the "Skill Creation Process" in order, skipping steps only if there is a clear reason why they are not applicable.
+
+### Step 1: Understanding the Skill with Concrete Examples
+
+Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.
+
+To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.
+
+For example, when building an image-editor skill, relevant questions include:
+
+- "What functionality should the image-editor skill support? Editing, rotating, anything else?"
+- "Can you give some examples of how this skill would be used?"
+- "I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?"
+- "What would a user say that should trigger this skill?"
+
+To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.
+
+Conclude this step when there is a clear sense of the functionality the skill should support.
+
+### Step 2: Planning the Reusable Skill Contents
+
+To turn concrete examples into an effective skill, analyze each example by:
+
+1. Considering how to execute on the example from scratch
+2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly
+
+Example: When building a `pdf-editor` skill to handle queries like "Help me rotate this PDF," the analysis shows:
+
+1. Rotating a PDF requires re-writing the same code each time
+2. A `scripts/rotate_pdf.py` script would be helpful to store in the skill
+
+Example: When designing a `frontend-webapp-builder` skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows:
+
+1. Writing a frontend webapp requires the same boilerplate HTML/React each time
+2. An `assets/hello-world/` template containing the boilerplate HTML/React project files would be helpful to store in the skill
+
+Example: When building a `big-query` skill to handle queries like "How many users have logged in today?" the analysis shows:
+
+1. Querying BigQuery requires re-discovering the table schemas and relationships each time
+2. A `references/schema.md` file documenting the table schemas would be helpful to store in the skill
+
+To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.
+
+### Step 3: Initializing the Skill
+
+At this point, it is time to actually create the skill.
+
+Skip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step.
+
+When creating a new skill from scratch, always run the `init_skill.py` script. The script conveniently generates a new template skill directory that automatically includes everything a skill requires, making the skill creation process much more efficient and reliable.
+
+Usage:
+
+```bash
+scripts/init_skill.py <skill-name> --path <output-directory>
+```
+
+The script:
+
+- Creates the skill directory at the specified path
+- Generates a SKILL.md template with proper frontmatter and TODO placeholders
+- Creates example resource directories: `scripts/`, `references/`, and `assets/`
+- Adds example files in each directory that can be customized or deleted
+
+After initialization, customize or remove the generated SKILL.md and example files as needed.
+
+### Step 4: Edit the Skill
+
+When editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of Claude to use. Focus on including information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively.
+
+#### Start with Reusable Skill Contents
+
+To begin implementation, start with the reusable resources identified above: `scripts/`, `references/`, and `assets/` files. Note that this step may require user input. For example, when implementing a `brand-guidelines` skill, the user may need to provide brand assets or templates to store in `assets/`, or documentation to store in `references/`.
+
+Also, delete any example files and directories not needed for the skill. The initialization script creates example files in `scripts/`, `references/`, and `assets/` to demonstrate structure, but most skills won't need all of them.
+
+#### Update SKILL.md
+
+**Writing Style:** Write the entire skill using **imperative/infinitive form** (verb-first instructions), not second person. Use objective, instructional language (e.g., "To accomplish X, do Y" rather than "You should do X" or "If you need to do X"). This maintains consistency and clarity for AI consumption.
+
+To complete SKILL.md, answer the following questions:
+
+1. What is the purpose of the skill, in a few sentences?
+2. When should the skill be used?
+3. In practice, how should Claude use the skill? All reusable skill contents developed above should be referenced so that Claude knows how to use them.
+
+### Step 5: Packaging a Skill
+
+Once the skill is ready, it should be packaged into a distributable zip file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements:
+
+```bash
+scripts/package_skill.py <path/to/skill-folder>
+```
+
+Optional output directory specification:
+
+```bash
+scripts/package_skill.py <path/to/skill-folder> ./dist
+```
+
+The packaging script will:
+
+1. **Validate** the skill automatically, checking:
+   - YAML frontmatter format and required fields
+   - Skill naming conventions and directory structure
+   - Description completeness and quality
+   - File organization and resource references
+
+2. **Package** the skill if validation passes, creating a zip file named after the skill (e.g., `my-skill.zip`) that includes all files and maintains the proper directory structure for distribution.
+
+If validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.
+
+### Step 6: Iterate
+
+After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.
+
+**Iteration workflow:**
+1. Use the skill on real tasks
+2. Notice struggles or inefficiencies
+3. Identify how SKILL.md or bundled resources should be updated
+4. Implement changes and test again

+## Structuring This Skill
+
+[TODO: Choose the structure that best fits this skill's purpose. Common patterns:
+
+**1. Workflow-Based** (best for sequential processes)
+- Works well when there are clear step-by-step procedures
+- Example: DOCX skill with "Workflow Decision Tree" → "Reading" → "Creating" → "Editing"
+- Structure: ## Overview → ## Workflow Decision Tree → ## Step 1 → ## Step 2...
+
+**2. Task-Based** (best for tool collections)
+- Works well when the skill offers different operations/capabilities
+- Example: PDF skill with "Quick Start" → "Merge PDFs" → "Split PDFs" → "Extract Text"
+- Structure: ## Overview → ## Quick Start → ## Task Category 1 → ## Task Category 2...
+
+**3. Reference/Guidelines** (best for standards or specifications)
+- Works well for brand guidelines, coding standards, or requirements
+- Example: Brand styling with "Brand Guidelines" → "Colors" → "Typography" → "Features"
+- Structure: ## Overview → ## Guidelines → ## Specifications → ## Usage...
+
+**4. Capabilities-Based** (best for integrated systems)
+- Works well when the skill provides multiple interrelated features
+- Example: Product Management with "Core Capabilities" → numbered capability list
+- Structure: ## Overview → ## Core Capabilities → ### 1. Feature → ### 2. Feature...
+
+Patterns can be mixed and matched as needed. Most skills combine patterns (e.g., start with task-based, add workflow for complex operations).
+
+Delete this entire "Structuring This Skill" section when done - it's just guidance.]
+
+## [TODO: Replace with the first main section based on chosen structure]
+
+[TODO: Add content here. See examples in existing skills:
+- Code samples for technical skills
+- Decision trees for complex workflows
+- Concrete examples with realistic user requests
+- References to scripts/templates/references as needed]
+
+## Resources
+
+This skill includes example resource directories that demonstrate how to organize different types of bundled resources:
+
+### scripts/
+Executable code (Python/Bash/etc.) that can be run directly to perform specific operations.
+
+**Examples from other skills:**
+- PDF skill: `fill_fillable_fields.py`, `extract_form_field_info.py` - utilities for PDF manipulation
+- DOCX skill: `document.py`, `utilities.py` - Python modules for document processing
+
+**Appropriate for:** Python scripts, shell scripts, or any executable code that performs automation, data processing, or specific operations.
+
+**Note:** Scripts may be executed without loading into context, but can still be read by Claude for patching or environment adjustments.
+
+### references/
+Documentation and reference material intended to be loaded into context to inform Claude's process and thinking.
+
+**Examples from other skills:**
+- Product management: `communication.md`, `context_building.md` - detailed workflow guides
+- BigQuery: API reference documentation and query examples
+- Finance: Schema documentation, company policies
+
+**Appropriate for:** In-depth documentation, API references, database schemas, comprehensive guides, or any detailed information that Claude should reference while working.
+
+### assets/
+Files not intended to be loaded into context, but rather used within the output Claude produces.
+
+**Examples from other skills:**
+- Brand styling: PowerPoint template files (.pptx), logo files
+- Frontend builder: HTML/React boilerplate project directories
+- Typography: Font files (.ttf, .woff2)
+
+**Appropriate for:** Templates, boilerplate code, document templates, images, icons, fonts, or any files meant to be copied or used in the final output.
+
+---
+
+**Any unneeded directories can be deleted.** Not every skill requires all three types of resources.

+name: standalone-component-migrator
+description: This skill should be used when converting Angular NgModule-based components to standalone architecture. It handles dependency analysis, template scanning, route refactoring, and test updates. Use this skill when the user requests component migration to standalone, mentions "convert to standalone", or wants to modernize Angular components to the latest patterns.
+---
+
+# Standalone Component Migrator
+
+## Overview
+
+Automate the conversion of Angular components from NgModule-based architecture to standalone components with explicit imports. This skill analyzes component dependencies, updates routing configurations, migrates tests, and optionally converts to modern Angular control flow syntax (@if, @for, @switch).
+
+## When to Use This Skill
+
+Invoke this skill when:
+- User requests component conversion to standalone
+- User mentions "migrate to standalone" or "modernize component"
+- User wants to remove NgModule declarations
+- User references Angular's standalone component architecture
+
+## Migration Workflow
+
+### Step 1: Analyze Component Dependencies
+
+1. **Read Component File**
+   - Identify component decorator configuration
+   - Note selector, template path, style paths
+   - Check if already standalone
+
+2. **Analyze Template**
+   - Read template file (HTML)
+   - Scan for directives: `*ngIf`, `*ngFor`, `*ngSwitch` → requires CommonModule
+   - Scan for forms: `ngModel`, `formControl` → requires FormsModule or ReactiveFormsModule
+   - Scan for built-in pipes: `async`, `date`, `json` → CommonModule
+   - Scan for custom components: identify all component selectors
+   - Scan for router directives: `routerLink`, `router-outlet` → RouterModule
+
+3. **Find Parent NgModule**
+   - Search for NgModule that declares this component
+   - Read NgModule file to understand current imports
+
+### Step 2: Convert Component to Standalone
+
+Add `standalone: true` and explicit imports array:
+
+```typescript
+// BEFORE
+import { Component } from '@angular/core';
+
+@Component({
+  selector: 'app-my-component',
+  templateUrl: './my-component.component.html'
+})
+export class MyComponent { }
+
+// AFTER
+import { Component } from '@angular/core';
+import { CommonModule } from '@angular/common';
+import { FormsModule } from '@angular/forms';
+import { RouterModule } from '@angular/router';
+import { ChildComponent } from './child.component';
+import { CustomPipe } from '@isa/utils/pipes';
+
+@Component({
+  selector: 'app-my-component',
+  standalone: true,
+  imports: [
+    CommonModule,
+    FormsModule,
+    RouterModule,
+    ChildComponent,
+    CustomPipe
+  ],
+  templateUrl: './my-component.component.html'
+})
+export class MyComponent { }
+```
+
+### Step 3: Update Parent NgModule
+
+Remove component from declarations, add to imports if exported:
+
+```typescript
+// BEFORE
+@NgModule({
+  declarations: [MyComponent, OtherComponent],
+  imports: [CommonModule],
+  exports: [MyComponent]
+})
+
+// AFTER
+@NgModule({
+  declarations: [OtherComponent],
+  imports: [CommonModule, MyComponent], // Import standalone component
+  exports: [MyComponent]
+})
+```
+
+If NgModule becomes empty (no declarations), consider removing it entirely.
+
+### Step 4: Update Routes (if applicable)
+
+Convert to lazy-loaded standalone component:
+
+```typescript
+// BEFORE
+const routes: Routes = [
+  { path: 'feature', component: MyComponent }
+];
+
+// AFTER (lazy loading)
+const routes: Routes = [
+  {
+    path: 'feature',
+    loadComponent: () => import('./my-component.component').then(m => m.MyComponent)
+  }
+];
+```
+
+### Step 5: Update Tests
+
+Convert test configuration:
+
+```typescript
+// BEFORE
+TestBed.configureTestingModule({
+  declarations: [MyComponent],
+  imports: [CommonModule, FormsModule]
+});
+
+// AFTER
+TestBed.configureTestingModule({
+  imports: [MyComponent] // Component imports its own dependencies
+});
+```
+
+### Step 6: Optional - Migrate to Modern Control Flow
+
+If requested, convert to new Angular control flow syntax:
+
+```typescript
+// OLD
+<div *ngIf="condition">Content</div>
+<div *ngFor="let item of items; trackBy: trackById">{{ item.name }}</div>
+<div [ngSwitch]="value">
+  <div *ngSwitchCase="'a'">A</div>
+  <div *ngSwitchDefault>Default</div>
+</div>
+
+// NEW
+@if (condition) {
+  <div>Content</div>
+}
+@for (item of items; track item.id) {
+  <div>{{ item.name }}</div>
+}
+@switch (value) {
+  @case ('a') { <div>A</div> }
+  @default { <div>Default</div> }
+}
+```
+
+### Step 7: Validate and Test
+
+1. **Compile Check**
+   ```bash
+   npx tsc --noEmit
+   ```
+
+2. **Run Tests**
+   ```bash
+   npx nx test [library-name] --skip-nx-cache
+   ```
+
+3. **Lint Check**
+   ```bash
+   npx nx lint [library-name]
+   ```
+
+4. **Verify Application Runs**
+   ```bash
+   npm start
+   ```
+
+## Common Import Patterns
+
+| Template Usage | Required Import |
+|---------------|-----------------|
+| `*ngIf`, `*ngFor`, `*ngSwitch` | `CommonModule` |
+| `ngModel` | `FormsModule` |
+| `formControl`, `formGroup` | `ReactiveFormsModule` |
+| `routerLink`, `router-outlet` | `RouterModule` |
+| `async`, `date`, `json` pipes | `CommonModule` |
+| Custom components | Direct component import |
+| Custom pipes | Direct pipe import |
+
+## Error Handling
+
+**Issue: Circular dependencies**
+- Extract shared interfaces to util library
+- Use dependency injection for services
+- Avoid component A importing component B when B imports A
+
+**Issue: Missing imports causing template errors**
+- Check browser console for specific errors
+- Verify all template dependencies are in imports array
+- Use Angular Language Service in IDE for hints

+name: swagger-sync-manager
+description: This skill should be used when regenerating Swagger/OpenAPI TypeScript API clients in the ISA-Frontend monorepo. It handles generation of all 10 API clients (or specific ones), Unicode cleanup, breaking change detection, TypeScript validation, and affected test execution. Use this skill when the user requests API sync, mentions "regenerate swagger", or indicates backend API changes.
+---
+
+# Swagger Sync Manager
+
+## Overview
+
+Automate the regeneration of TypeScript API clients from Swagger/OpenAPI specifications. Handles 10 API clients with automatic post-processing, breaking change detection, impact analysis, and validation.
+
+## When to Use This Skill
+
+Invoke when user requests:
+- API client regeneration
+- "sync swagger" or "update API clients"
+- Backend API changes need frontend updates
+
+## Available APIs
+
+availability-api, cat-search-api, checkout-api, crm-api, eis-api, inventory-api, isa-api, oms-api, print-api, wws-api
+
+## Sync Workflow
+
+### Step 1: Pre-Generation Check
+
+```bash
+# Check uncommitted changes
+git status generated/swagger/
+```
+
+If changes exist, warn user and ask to proceed.
+
+### Step 2: Backup Current State (Optional)
+
+```bash
+cp -r generated/swagger generated/swagger.backup.$(date +%s)
+```
+
+### Step 3: Run Generation
+
+```bash
+# All APIs
+npm run generate:swagger
+
+# Specific API (if api-name provided)
+npm run generate:swagger:[api-name]
+```
+
+### Step 4: Verify Unicode Cleanup
+
+Check `tools/fix-files.js` executed. Scan for remaining Unicode issues:
+
+```bash
+grep -r "\\\\u00" generated/swagger/ || echo "✅ No Unicode issues"
+```
+
+### Step 5: Detect Breaking Changes
+
+For each modified API:
+
+```bash
+git diff generated/swagger/[api-name]/
+```
+
+Identify:
+- 🔴 Removed properties
+- 🔴 Changed types
+- 🔴 Removed endpoints
+- ✅ Added properties (safe)
+- ✅ New endpoints (safe)
+
+### Step 6: Impact Analysis
+
+Use `Explore` agent to find affected files:
+- Search for imports from `@generated/swagger/[api-name]`
+- List data-access services using changed APIs
+- Estimate refactoring scope
+
+### Step 7: Validate
+
+```bash
+# TypeScript compilation
+npx tsc --noEmit
+
+# Run affected tests
+npx nx affected:test --skip-nx-cache
+
+# Lint affected
+npx nx affected:lint
+```
+
+### Step 8: Generate Report
+
+```
+Swagger Sync Complete
+=====================
+
+APIs Regenerated: [all | specific]
+Files Changed: XX
+Breaking Changes: XX
+
+🔴 Breaking Changes
+-------------------
+- [API]: [Property removed/type changed]
+- Affected files: [list]
+
+✅ Compatible Changes
+---------------------
+- [API]: [New properties/endpoints]
+
+📊 Validation
+-------------
+TypeScript: ✅/❌
+Tests: XX/XX passing
+Lint: ✅/❌
+
+💡 Next Steps
+-------------
+[Fix breaking changes / Deploy]
+```
+
+## Error Handling
+
+**Generation fails**: Check OpenAPI spec URLs in package.json
+
+**Unicode cleanup fails**: Run `node tools/fix-files.js` manually
+
+**TypeScript errors**: Review breaking changes, update affected services

+name: tailwind
+description: This skill should be used when working with Tailwind CSS styling in the ISA-Frontend project. Use it when writing component styles, choosing color values, applying typography, creating buttons, or determining appropriate spacing and layout utilities. Essential for maintaining design system consistency.
+---
+
+# ISA Tailwind Design System
+
+## Overview
+
+Assist with applying the ISA-specific Tailwind CSS design system throughout the ISA-Frontend Angular monorepo. This skill provides comprehensive knowledge of custom utilities, color palettes, typography classes, button variants, and layout patterns specific to this project.
+
+## When to Use This Skill
+
+Invoke this skill when:
+- **After** checking `libs/ui/**` for existing components (always check first!)
+- Styling layout and spacing for components
+- Choosing appropriate color values for custom elements
+- Applying typography classes to text content
+- Determining spacing, layout, or responsive breakpoints
+- Customizing or extending existing UI components
+- Ensuring design system consistency
+- Questions about which Tailwind utility classes are available
+
+**Important**: This skill provides Tailwind utilities. Always prefer using components from `@isa/ui/*` libraries before applying custom Tailwind styles.
+
+**Works together with:**
+- **[angular-template](../angular-template/SKILL.md)** - Angular template syntax, control flow (@if, @for, @defer), and binding patterns
+- **[html-template](../html-template/SKILL.md)** - E2E testing attributes (`data-what`, `data-which`) and ARIA accessibility
+
+When building Angular components, these three skills work together:
+1. Use **angular-template** for Angular syntax and control flow
+2. Use **html-template** for `data-*` and ARIA attributes
+3. Use **tailwind** (this skill) for styling with the ISA design system
+
+## Core Design System Principles
+
+### 0. Component Libraries First (Most Important)
+
+**Always check `libs/ui/**` for existing components before writing custom Tailwind styles.**
+
+The project has 17 specialized UI component libraries:
+- `@isa/ui/buttons` - Button components
+- `@isa/ui/dialogs` - Dialog/modal components
+- `@isa/ui/inputs` - Input field components
+- `@isa/ui/forms` - Form components
+- `@isa/ui/cards` - Card components
+- `@isa/ui/layout` - Layout components (including breakpoint service)
+- `@isa/ui/tables` - Table components
+- And 10+ more specialized libraries
+
+**Workflow**:
+1. First, search for existing components in `libs/ui/**` that match your needs
+2. If found, import and use the component (prefer composition over custom styling)
+3. Only use Tailwind utilities for:
+   - Layout/spacing adjustments
+   - Component-specific customizations
+   - Cases where no suitable UI component exists
+
+**Example**:
+```typescript
+// ✅ Correct - Use existing component
+import { ButtonComponent } from '@isa/ui/buttons';
+
+// ❌ Wrong - Don't recreate with Tailwind
+<button class="btn btn-accent-1">...</button>
+```
+
+### 1. ISA-Prefixed Colors Only
+
+**Always use `isa-*` prefixed color utilities.** Other color names exist only for backwards compatibility and should not be used in new code.
+
+**Correct color usage**:
+- `bg-isa-accent-red`, `bg-isa-accent-blue`, `bg-isa-accent-green`
+- `bg-isa-secondary-100` through `bg-isa-secondary-900`
+- `bg-isa-neutral-100` through `bg-isa-neutral-900`
+- `text-isa-white`, `text-isa-black`
+
+**Example**:
+```html
+<!-- ✅ Correct -->
+<div class="bg-isa-accent-red text-isa-white">Error message</div>
+<button class="bg-isa-secondary-600 hover:bg-isa-secondary-700">Action</button>
+
+<!-- ❌ Wrong - deprecated colors -->
+<div class="bg-accent-1 text-accent-1-content">...</div>
+<div class="bg-brand">...</div>
+```
+
+### 2. ISA-Prefixed Typography
+
+Always use ISA typography classes instead of arbitrary font sizes:
+- **Headings**: `.isa-text-heading-1-bold`, `.isa-text-heading-2-bold`, `.isa-text-heading-3-bold`
+- **Subtitles**: `.isa-text-subtitle-1-bold`, `.isa-text-subtitle-2-bold`
+- **Body**: `.isa-text-body-1-regular`, `.isa-text-body-1-bold`, `.isa-text-body-2-regular`, `.isa-text-body-2-bold`
+- **Captions**: `.isa-text-caption-regular`, `.isa-text-caption-bold`, `.isa-text-caption-caps`
+
+### 3. Responsive Design with Breakpoint Service
+
+Prefer the breakpoint service from `@isa/ui/layout` for reactive breakpoint detection:
+
+```typescript
+import { breakpoint, Breakpoint } from '@isa/ui/layout';
+
+// In component
+isDesktop = breakpoint([Breakpoint.Desktop, Breakpoint.DekstopL, Breakpoint.DekstopXL]);
+```
+
+```html
+@if (isDesktop()) {
+  <div class="desktop-layout">...</div>
+}
+```
+
+Only use Tailwind breakpoint utilities (`isa-desktop:`, `isa-desktop-l:`, `isa-desktop-xl:`) when the breakpoint service is not appropriate (e.g., pure CSS solutions).
+
+## Quick Reference
+
+### Typography Selection Guide
+
+**Headings**:
+- Large hero text: `.isa-text-heading-1-bold` (60px)
+- Section headers: `.isa-text-heading-2-bold` (48px)
+- Subsection headers: `.isa-text-heading-3-bold` (40px)
+
+**Subtitles**:
+- Prominent subtitles: `.isa-text-subtitle-1-bold` (28px)
+- Section labels: `.isa-text-subtitle-2-bold` (16px, uppercase)
+
+**Body Text**:
+- Standard text: `.isa-text-body-1-regular` (16px)
+- Emphasized text: `.isa-text-body-1-bold` (16px)
+- Smaller text: `.isa-text-body-2-regular` (14px)
+- Smaller emphasized: `.isa-text-body-2-bold` (14px)
+
+**Captions**:
+- Small labels: `.isa-text-caption-regular` (12px)
+- Small emphasized: `.isa-text-caption-bold` (12px)
+- Uppercase labels: `.isa-text-caption-caps` (12px, uppercase)
+
+Each variant has `-big` and `-xl` responsive sizes for larger breakpoints.
+
+### Color Selection Guide
+
+**Always use `isa-*` prefixed colors. Other colors are deprecated.**
+
+**Status/Accent Colors**:
+- Success/Confirm: `bg-isa-accent-green`
+- Error/Danger: `bg-isa-accent-red`
+- Primary/Info: `bg-isa-accent-blue`
+
+**Brand Secondary Colors** (100 = lightest, 900 = darkest):
+- Very light: `bg-isa-secondary-100`, `bg-isa-secondary-200`
+- Light: `bg-isa-secondary-300`, `bg-isa-secondary-400`
+- Medium: `bg-isa-secondary-500`, `bg-isa-secondary-600`
+- Dark: `bg-isa-secondary-700`, `bg-isa-secondary-800`
+- Very dark: `bg-isa-secondary-900`
+
+**Neutral UI** (100 = lightest, 900 = darkest):
+- Light backgrounds: `bg-isa-neutral-100`, `bg-isa-neutral-200`, `bg-isa-neutral-300`
+- Medium backgrounds: `bg-isa-neutral-400`, `bg-isa-neutral-500`, `bg-isa-neutral-600`
+- Dark backgrounds/text: `bg-isa-neutral-700`, `bg-isa-neutral-800`, `bg-isa-neutral-900`
+
+**Basic Colors**:
+- White: `bg-isa-white`, `text-isa-white`
+- Black: `bg-isa-black`, `text-isa-black`
+
+**Example Usage**:
+```html
+<!-- Status indicators -->
+<div class="bg-isa-accent-green text-isa-white">Success</div>
+<div class="bg-isa-accent-red text-isa-white">Error</div>
+
+<!-- Backgrounds -->
+<div class="bg-isa-neutral-100">Light surface</div>
+<div class="bg-isa-secondary-600 text-isa-white">Brand element</div>
+```
+
+### Spacing Patterns
+
+**Component Padding**:
+- Cards: `p-card` (20px) or `p-5` (1.25rem)
+- General spacing: `p-4` (1rem), `p-6` (1.5rem), `p-8` (2rem)
+- Tight spacing: `p-2` (0.5rem), `p-3` (0.75rem)
+
+**Gap/Grid Spacing**:
+- Tight spacing: `gap-2` (0.5rem), `gap-3` (0.75rem)
+- Medium spacing: `gap-4` (1rem), `gap-6` (1.5rem)
+- Wide spacing: `gap-8` (2rem), `gap-10` (2.5rem)
+- Split screen: `gap-split-screen`
+
+**Note**: Prefer Tailwind's standard rem-based spacing (e.g., `p-4`, `gap-6`) over pixel-based utilities (`px-*`) for better scalability and accessibility.
+
+**Layout Heights**:
+- Split screen tablet: `h-split-screen-tablet`
+- Split screen desktop: `h-split-screen-desktop`
+
+### Z-Index Layering
+
+Apply semantic z-index values for proper layering:
+- Dropdowns: `z-dropdown` (50)
+- Sticky elements: `z-sticky` (100)
+- Fixed elements: `z-fixed` (150)
+- Modal backdrops: `z-modalBackdrop` (200)
+- Modals: `z-modal` (250)
+- Popovers: `z-popover` (300)
+- Tooltips: `z-tooltip` (350)
+
+## Common Styling Patterns
+
+**Important**: These are examples for when UI components don't exist. Always check `@isa/ui/*` libraries first!
+
+### Layout Spacing (Use Tailwind)
+```html
+<!-- Container with padding -->
+<div class="p-6">
+  <h2 class="isa-text-heading-2-bold mb-4">Section Title</h2>
+  <div class="flex flex-col gap-4">
+    <!-- Content items -->
+  </div>
+</div>
+```
+
+### Grid Layout (Use Tailwind)
+```html
+<!-- Responsive grid with gap -->
+<div class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
+  <!-- Grid items -->
+</div>
+```
+
+### Card Layout (Prefer @isa/ui/cards if available)
+```html
+<div class="bg-isa-white p-5 rounded shadow-card">
+  <h3 class="isa-text-subtitle-1-bold mb-4">Card Title</h3>
+  <p class="isa-text-body-1-regular">Card content...</p>
+</div>
+```
+
+### Form Group (Prefer @isa/ui/forms if available)
+```html
+<div class="flex flex-col gap-2">
+  <label class="isa-text-body-2-semibold text-isa-black">Field Label</label>
+  <!-- Use component from @isa/ui/inputs if available -->
+  <input class="shadow-input rounded border border-isa-neutral-400 p-2.5" />
+</div>
+```
+
+### Button Group (Use @isa/ui/buttons)
+```typescript
+// ✅ Preferred - Use component library
+import { ButtonComponent } from '@isa/ui/buttons';
+```
+
+```html
+<div class="flex gap-4">
+  <!-- Use actual button components from @isa/ui/buttons -->
+  <isa-button variant="primary">Save</isa-button>
+  <isa-button variant="secondary">Cancel</isa-button>
+</div>
+```
+
+### Split Screen Layout (Use Tailwind)
+```html
+<div class="grid grid-cols-split-screen gap-split-screen h-split-screen-desktop">
+  <aside class="bg-isa-neutral-100 p-5">Sidebar</aside>
+  <main class="bg-isa-white p-8">Content</main>
+</div>
+```

+- Verifying available shadow or radius utilities
+
+## Best Practices
+
+1. **Component libraries first**: Always check `libs/ui/**` before writing custom Tailwind styles
+2. **ISA-prefixed colors only**: Always use `isa-*` colors (e.g., `bg-isa-accent-red`, `text-isa-neutral-700`)
+3. **Use rem over px**: Prefer Tailwind's default rem-based spacing (e.g., `p-4`, `gap-6`) over pixel-based utilities
+4. **Typography system**: Never use arbitrary font sizes - always use `.isa-text-*` classes
+5. **Breakpoints**: Use breakpoint service from `@isa/ui/layout` for logic
+6. **Z-index**: Always use semantic z-index utilities, never arbitrary values
+7. **Consistency**: Always use design system utilities instead of arbitrary values
+
+## Anti-Patterns to Avoid
+
+❌ **Don't** use deprecated colors (backwards compatibility only):
+```html
+<div class="bg-accent-1">...</div> <!-- Wrong - deprecated -->
+<div class="bg-brand">...</div> <!-- Wrong - deprecated -->
+<div class="bg-surface">...</div> <!-- Wrong - deprecated -->
+<div class="bg-isa-secondary-600">...</div> <!-- Correct -->
+```
+
+❌ **Don't** use arbitrary values when utilities exist:
+```html
+<p class="text-[16px]">Text</p> <!-- Wrong -->
+<p class="isa-text-body-1-regular">Text</p> <!-- Correct -->
+```
+
+❌ **Don't** hardcode hex colors:
+```html
+<div class="bg-[#DF001B]">...</div> <!-- Wrong -->
+<div class="bg-isa-accent-red">...</div> <!-- Correct -->
+```
+
+❌ **Don't** recreate components with Tailwind:
+```html
+<button class="btn btn-accent-1">...</button> <!-- Wrong - use @isa/ui/buttons -->
+<isa-button variant="primary">...</isa-button> <!-- Correct -->
+```
+
+❌ **Don't** use arbitrary z-index:
+```html
+<div class="z-[999]">...</div> <!-- Wrong -->
+<div class="z-modal">...</div> <!-- Correct -->
+```
+
+✅ **Do** leverage the component libraries and ISA design system for consistency and maintainability.

+description: This skill should be used when migrating Angular libraries from Jest + Spectator to Vitest + Angular Testing Utilities. It handles test configuration updates, test file refactoring, mock pattern conversion, and validation. Use this skill when the user requests test framework migration, specifically for the 40 remaining Jest-based libraries in the ISA-Frontend monorepo.

+
+# Test Migration Specialist
+
+## Overview
+
+Automate the migration of Angular library tests from Jest + Spectator to Vitest + Angular Testing Utilities. This skill handles the complete migration workflow including configuration updates, test file refactoring, dependency management, and validation.
+
+**Current Migration Status**: 40 libraries use Jest (65.6%), 21 libraries use Vitest (34.4%)
+
+## When to Use This Skill
+
+Invoke this skill when:
+- User requests test migration for a specific library
+- User mentions "migrate tests" or "Jest to Vitest"
+- User wants to update test framework for a library
+- User references the 40 remaining libraries to migrate
+
+## Migration Workflow
+
+### Step 1: Pre-Migration Analysis
+
+Before making any changes, analyze the current state:
+
+1. **Read Testing Guidelines**
+   - Use `docs-researcher` agent to read `docs/guidelines/testing.md`
+   - Understand migration patterns and best practices
+   - Note JUnit and Cobertura configuration requirements
+
+2. **Analyze Library Structure**
+   - Read `libs/[path]/project.json` to identify current test executor
+   - Count test files using Glob: `**/*.spec.ts`
+   - Scan for Spectator usage patterns using Grep: `createComponentFactory|createServiceFactory|Spectator`
+   - Identify complex mocking scenarios (ng-mocks, jest.mock patterns)
+
+3. **Determine Library Depth**
+   - Calculate directory levels from workspace root
+   - This affects relative paths in vite.config.mts (../../../ vs ../../../../)
+
+### Step 2: Update Test Configuration
+
+Update the library's test configuration to use Vitest:
+
+1. **Update project.json**
+   Replace Jest executor with Vitest:
+   ```json
+   {
+     "test": {
+       "executor": "@nx/vite:test",
+       "options": {
+         "configFile": "vite.config.mts"
+       }
+     }
+   }
+   ```
+
+2. **Create vite.config.mts**
+   Create configuration with JUnit and Cobertura reporters:
+   ```typescript
+   /// <reference types='vitest' />
+   import { defineConfig } from 'vite';
+   import angular from '@analogjs/vite-plugin-angular';
+   import { nxViteTsPaths } from '@nx/vite/plugins/nx-tsconfig-paths.plugin';
+   import { nxCopyAssetsPlugin } from '@nx/vite/plugins/nx-copy-assets.plugin';
+
+   export default
+   // @ts-expect-error - Vitest reporter tuple types have complex inference issues
+   defineConfig(() => ({
+     root: __dirname,
+     cacheDir: '../../../node_modules/.vite/libs/[path]',
+     plugins: [angular(), nxViteTsPaths(), nxCopyAssetsPlugin(['*.md'])],
+     test: {
+       watch: false,
+       globals: true,
+       environment: 'jsdom',
+       include: ['{src,tests}/**/*.{test,spec}.{js,mjs,cjs,ts,mts,cts,jsx,tsx}'],
+       setupFiles: ['src/test-setup.ts'],
+       reporters: [
+         'default',
+         ['junit', { outputFile: '../../../testresults/junit-[library-name].xml' }],
+       ],
+       coverage: {
+         reportsDirectory: '../../../coverage/libs/[path]',
+         provider: 'v8' as const,
+         reporter: ['text', 'cobertura'],
+       },
+     },
+   }));
+   ```
+
+   **Critical**: Adjust `../../../` depth based on library location
+
+### Step 3: Migrate Test Files
+
+For each `.spec.ts` file, perform these conversions:
+
+1. **Update Imports**
+   ```typescript
+   // REMOVE
+   import { createComponentFactory, Spectator } from '@ngneat/spectator/jest';
+
+   // ADD
+   import { ComponentFixture, TestBed } from '@angular/core/testing';
+   import { describe, it, expect, beforeEach } from 'vitest';
+   ```
+
+2. **Convert Component Tests**
+   ```typescript
+   // OLD (Spectator)
+   const createComponent = createComponentFactory({
+     component: MyComponent,
+     imports: [CommonModule],
+     mocks: [MyService]
+   });
+
+   let spectator: Spectator<MyComponent>;
+   beforeEach(() => spectator = createComponent());
+
+   it('should display title', () => {
+     spectator.setInput('title', 'Test');
+     expect(spectator.query('h1')).toHaveText('Test');
+   });
+
+   // NEW (Angular Testing Utilities)
+   describe('MyComponent', () => {
+     let fixture: ComponentFixture<MyComponent>;
+     let component: MyComponent;
+
+     beforeEach(async () => {
+       await TestBed.configureTestingModule({
+         imports: [MyComponent, CommonModule],
+         providers: [{ provide: MyService, useValue: mockService }]
+       }).compileComponents();
+
+       fixture = TestBed.createComponent(MyComponent);
+       component = fixture.componentInstance;
+     });
+
+     it('should display title', () => {
+       component.title = 'Test';
+       fixture.detectChanges();
+       expect(fixture.nativeElement.querySelector('h1').textContent).toContain('Test');
+     });
+   });
+   ```
+
+3. **Convert Service Tests**
+   ```typescript
+   // OLD (Spectator)
+   const createService = createServiceFactory({
+     service: MyService,
+     mocks: [HttpClient]
+   });
+
+   // NEW (Angular Testing Utilities)
+   describe('MyService', () => {
+     let service: MyService;
+     let httpMock: HttpTestingController;
+
+     beforeEach(() => {
+       TestBed.configureTestingModule({
+         imports: [HttpClientTestingModule],
+         providers: [MyService]
+       });
+
+       service = TestBed.inject(MyService);
+       httpMock = TestBed.inject(HttpTestingController);
+     });
+
+     afterEach(() => {
+       httpMock.verify();
+     });
+   });
+   ```
+
+4. **Update Mock Patterns**
+   - Replace `jest.fn()` → `vi.fn()`
+   - Replace `jest.spyOn()` → `vi.spyOn()`
+   - Replace `jest.mock()` → `vi.mock()`
+   - For complex mocks, use `ng-mocks` library if needed
+
+5. **Update Matchers**
+   - Replace Spectator matchers (`toHaveText`, `toExist`) with standard Jest/Vitest matchers
+   - Use `expect().toBeTruthy()`, `expect().toContain()`, etc.
+
+### Step 4: Verify E2E Attributes
+
+Check component templates for E2E testing attributes:
+
+1. **Scan Templates**
+   Use Grep to find templates: `**/*.html`
+
+2. **Validate Attributes**
+   Ensure interactive elements have:
+   - `data-what`: Semantic description (e.g., "submit-button")
+   - `data-which`: Unique identifier (e.g., "form-primary")
+   - Dynamic `data-*` for list items: `[attr.data-item-id]="item.id"`
+
+3. **Add Missing Attributes**
+   If missing, add them to components. See `dev:add-e2e-attrs` command or use that skill.
+
+### Step 5: Run Tests and Validate
+
+Execute tests to verify migration:
+
+1. **Run Tests**
+   ```bash
+   npx nx test [library-name] --skip-nx-cache
+   ```
+
+2. **Run with Coverage**
+   ```bash
+   npx nx test [library-name] --coverage.enabled=true --skip-nx-cache
+   ```
+
+3. **Verify Output Files**
+   Check that CI/CD integration files are created:
+   - JUnit XML: `testresults/junit-[library-name].xml`
+   - Cobertura XML: `coverage/libs/[path]/cobertura-coverage.xml`
+
+4. **Address Failures**
+   If tests fail:
+   - Review test conversion (common issues: missing fixture.detectChanges(), incorrect selectors)
+   - Check mock configurations
+   - Verify imports are correct
+   - Ensure async tests use proper patterns
+
+### Step 6: Clean Up
+
+Remove legacy configurations:
+
+1. **Remove Jest Files**
+   - Delete `jest.config.ts` or `jest.config.js` if present
+   - Remove Jest-specific setup files
+
+2. **Update Dependencies**
+   - Note if Spectator can be removed (check if other libs still use it)
+   - Note if Jest can be removed (check if other libs still use it)
+   - Don't actually remove from package.json unless all libs migrated
+
+3. **Update Documentation**
+   Update library README.md with new test commands:
+   ```markdown
+   ## Testing
+
+   This library uses Vitest + Angular Testing Utilities.
+
+   ```bash
+   # Run tests
+   npx nx test [library-name] --skip-nx-cache
+
+   # Run with coverage
+   npx nx test [library-name] --coverage.enabled=true --skip-nx-cache
+   ```
+   ```
+
+### Step 7: Generate Migration Report
+
+Provide comprehensive migration summary:
+
+```

+
+# Type Safety Engineer
+
+## Overview
+
+Enhance TypeScript type safety by eliminating `any` types, adding Zod schemas for runtime validation, creating type guards, and strengthening compiler strictness.
+
+## When to Use This Skill
+
+Invoke when user wants to:
+- Remove `any` types
+- Add runtime validation with Zod
+- Improve type safety
+- Mentioned "type safety" or "Zod schemas"
+
+## Type Safety Workflow
+
+### Step 1: Scan for Issues
+
+```bash
+# Find explicit any
+grep -r ": any" libs/ --include="*.ts" | grep -v ".spec.ts"
+
+# Find functions without return types
+grep -r "^.*function.*{$" libs/ --include="*.ts" | grep -v ": "
+
+# TypeScript strict mode check
+npx tsc --noEmit --strict
+```
+
+### Step 2: Categorize Issues
+
+**🔴 Critical:**
+- `any` in API response handling
+- `any` in service methods
+- `any` in store state types
+
+**⚠️ Important:**
+- Missing return types
+- Untyped parameters
+- Weak types (`object`, `Function`)
+
+**ℹ️ Moderate:**
+- `any` in test files
+- Loose array types
+
+### Step 3: Add Zod Schemas for API Responses
+
+```typescript
+import { z } from 'zod';
+
+// Define schema
+const OrderItemSchema = z.object({
+  productId: z.string().uuid(),
+  quantity: z.number().int().positive(),
+  price: z.number().positive()
+});
+
+const OrderResponseSchema = z.object({
+  id: z.string().uuid(),
+  status: z.enum(['pending', 'confirmed', 'shipped']),
+  items: z.array(OrderItemSchema),
+  createdAt: z.string().datetime()
+});
+
+// Infer TypeScript type
+type OrderResponse = z.infer<typeof OrderResponseSchema>;
+
+// Runtime validation
+const order = OrderResponseSchema.parse(apiResponse);
+```
+
+### Step 4: Replace `any` with Specific Types
+
+**Pattern 1: Unknown + Type Guards**
+```typescript
+// BEFORE
+function processData(data: any) {
+  return data.value;
+}
+
+// AFTER
+function processData(data: unknown): string {
+  if (!isValidData(data)) {
+    throw new Error('Invalid data');
+  }
+  return data.value;
+}
+
+function isValidData(data: unknown): data is { value: string } {
+  return typeof data === 'object' && data !== null && 'value' in data;
+}
+```
+
+**Pattern 2: Generic Types**
+```typescript
+// BEFORE
+function findById(items: any[], id: string): any {
+  return items.find(item => item.id === id);
+}
+
+// AFTER
+function findById<T extends { id: string }>(items: T[], id: string): T | undefined {
+  return items.find(item => item.id === id);
+}
+```
+
+### Step 5: Add Type Guards for API Data
+
+```typescript
+export function isOrderResponse(data: unknown): data is OrderResponse {
+  try {
+    OrderResponseSchema.parse(data);
+    return true;
+  } catch {
+    return false;
+  }
+}
+
+// Use in service
+getOrder(id: string): Observable<OrderResponse> {
+  return this.http.get(`/api/orders/${id}`).pipe(
+    map(response => {
+      if (!isOrderResponse(response)) {
+        throw new Error('Invalid API response');
+      }
+      return response;
+    })
+  );
+}
+```
+
+### Step 6: Validate Changes
+
+```bash
+npx tsc --noEmit --strict
+npx nx affected:test --skip-nx-cache
+npx nx affected:lint
+```
+
+### Step 7: Generate Report
+
+```

+
+## Common Patterns
+
+**API Response Validation:**
+```typescript
+const schema = z.object({...});
+type Type = z.infer<typeof schema>;
+
+return this.http.get<unknown>(url).pipe(
+  map(response => schema.parse(response))
+);

+## ISA Frontend – AI Assistant Working Rules
+
+Concise, project-specific guidance so an AI agent can be productive quickly. Focus on THESE patterns; avoid generic boilerplate.
+
+### 1. Monorepo & Tooling
+
+- Nx workspace (Angular 20 + Libraries under `libs/**`, main app `apps/isa-app`).
+- Scripts (see `package.json`):
+  - Dev serve: `npm start` (=> `nx serve isa-app --ssl`).
+  - Library tests (exclude app): `npm test` (Jest + emerging Vitest). CI uses `npm run ci`.
+  - Build dev: `npm run build`; prod: `npm run build-prod`.
+  - Storybook: `npm run storybook`.
+  - Swagger codegen: `npm run generate:swagger` then `npm run fix:files:swagger`.
+- Default branch in Nx: `develop` (`nx.json: defaultBase`). Use affected commands when adding libs.
+- Node >=22, TS 5.8, ESLint flat config (`eslint.config.js`).

+
+Guidelines: create new code in the closest domain folder; expose public API via each lib `src/index.ts`; follow existing naming (`feature-name.type.ts`). Keep generated swagger untouched—extend via wrapper libs if needed.
+
+### 1.b Import Path Aliases
+
+Use existing TS path aliases (see `tsconfig.base.json`) instead of long relative paths:
+
+Core / Cross-cutting:
+
+- `@isa/core/logging`, `@isa/core/config`, `@isa/core/storage`, `@isa/core/tabs`, `@isa/core/notifications`
+
+Domain & Features:
+
+- Catalogue: `@isa/catalogue/data-access`
+- Customer: `@isa/customer/data-access`
+- OMS features: `@isa/oms/feature/return-details`, `.../return-process`, `.../return-review`, `.../return-search`, `.../return-summary`
+- OMS shared: `@isa/oms/shared/product-info`, `@isa/oms/shared/task-list`
+- Remission: `@isa/remission/data-access`, feature libs (`@isa/remission/feature/remission-return-receipt-details`, `...-list`) and shared (`@isa/remission/shared/remission-start-dialog`, `.../search-item-to-remit-dialog`, `.../return-receipt-actions`, `.../product`)
+
+Shared / UI:
+
+- Shared libs: `@isa/shared/scanner`, `@isa/shared/filter`, `@isa/shared/product-image`, `@isa/shared/product-router-link`, `@isa/shared/product-format`
+- UI components: `@isa/ui/buttons`, `@isa/ui/dialog`, `@isa/ui/input-controls`, `@isa/ui/layout`, `@isa/ui/menu`, `@isa/ui/toolbar`, etc. (one alias per folder under `libs/ui/*`)
+- Icons: `@isa/icons`
+
+Utilities:
+
+- `@isa/utils/ean-validation`, `@isa/utils/z-safe-parse`, `@isa/utils/scroll-position`
+
+Generated Swagger Clients:
+
+- `@generated/swagger/isa-api`, `@generated/swagger/oms-api`, `@generated/swagger/inventory-api`, etc. (one per subfolder). Never edit generated sources—wrap in a domain lib if extension needed.
+
+App-local (only inside `apps/isa-app` context):
+
+- Namespaced folders: `@adapter/*`, `@domain/*`, `@hub/*`, `@modal/*`, `@page/*`, `@shared/*` (and nested: `@shared/components/*`, `@shared/services/*`, etc.), `@ui/*`, `@utils/*`, `@swagger/*`.
+
+Patterns:
+
+- Always add new reusable code as a library then expose via an `@isa/...` alias; do not add new generic code under app-local aliases if it may be reused later.
+- When introducing a new library ensure its `src/index.ts` re-exports only stable public surface; internal helpers stay un-exported.
+- For new generated API groups, extend via thin wrappers in a domain `data-access` lib rather than patching generated code.
+
+### 2. Testing Strategy
+
+- Legacy tests: Jest (`@nx/jest:jest`). New feature libs (e.g. remission feature) use Vitest + Vite plugin (`vite.config.mts`).
+- When adding a new library today prefer Vitest unless consistency with existing Jest-only area is required.
+- Do NOT mix frameworks inside one lib. Check presence of `vite.config.*` to know it is Vitest-enabled.
+- App (`isa-app`) still uses Jest.
+
+### 3. Architecture & Cross-Cutting Services
+
+- Core libraries underpin features: `@isa/core/logging`, `@isa/core/config`, `@isa/core/storage`.
+- Feature domains grouped (e.g. `libs/remission/**`, `libs/shared/**`, `libs/common/**`). Keep domain-specific code there; UI-only pieces in `ui/` or `shared/`.
+- Prefer standalone components but some legacy components set `standalone: false` (see `MainComponent`). Maintain existing pattern unless doing a focused migration.
+
+### 4. Logging (Critical Pattern)
+
+- Central logging via `@isa/core/logging` (files: `logging.service.ts`, `logging.providers.ts`).
+- Configure once in app config using provider builders: `provideLogging(withLogLevel(...), withSink(ConsoleLogSink), withContext({...}))`.
+- Use factory `logger(() => ({ dynamicContext }))` (see README) rather than injecting `LoggingService` directly unless extending framework code.
+- Context hierarchy: global -> component (`provideLoggerContext`) -> instance (factory param) -> message (callback arg). Always pass context as lazy function `() => ({ ... })` for perf.
+- Respect log level threshold; do not perform expensive serialization before calling (let sinks handle it or gate behind dev checks).
+
+### 5. Configuration Access
+
+- Use `Config` service (`@isa/core/config/src/lib/config.ts`). Fetch values with Zod schema: `config.get('licence.scandit', z.string())` (see `SCANDIT_LICENSE` token). Avoid deprecated untyped access.
+
+### 6. Storage & State Persistence
+
+- Storage abstraction: `injectStorage(SomeProvider)` wraps a `StorageProvider` (local/session/indexedDB/custom user storage) and prefixes keys with current authenticated user `sub` (OAuth `sub` fallback 'anonymous').
+- When adding persisted signal stores, use `withStorage(storageKey, ProviderType)` feature (`signal-store-feature.ts`) to auto debounce-save (1s) + restore on init. Only pass plain serializable state.
+
+### 7. Signals & State
+
+- Internal state often via Angular signals & NgRx Signals (`@ngrx/signals`). Avoid manual subscriptions—prefer computed/signals and `rxMethod` for side effects.
+- When persisting, ensure objects are JSON-safe; validation via Zod if deserializing external data.
+
+#### 7.a NgRx Signals Deep Dive
+
+Core building blocks we use:
+
+- `signalStore(...)` + features: `withState`, `withComputed`, `withMethods`, `withHooks`, `withStorage` (custom feature in `core/storage`).
+- `rxMethod` (from `@ngrx/signals/rxjs-interop`) to bridge imperative async flows (HTTP calls, debounce, switchMap) into store-driven mutations.
+- `getState`, `patchState` for immutable, shallow merges; avoid manually mutating nested objects—spread + patch.
+
+Patterns:
+
+1. Store Shape: Keep initial state small & serializable (no class instances, functions, DOM nodes). Derive heavy or view-specific projections with `withComputed`.
+2. Side Effects: Wrap fetch/update flows inside `rxMethod` pipes; ensure cancellation semantics (`switchMap`) to drop stale requests.
+3. Persistence: Apply `withStorage(key, Provider)` last so hooks run after other features; persisted state must be plain JSON (no Dates—convert to ISO strings). Debounce already handled (1s) in `withStorage`—do NOT add another debounce upstream unless burst traffic is extreme.
+4. Error Handling: Keep an `error` field in state for presentation; log via `logger()` at Warn/Error levels but do not store full Error object (serialize minimal fields: `message`, maybe `code`).
+5. Loading Flags: Prefer a boolean `loading` OR a discriminated union `status: 'idle'|'loading'|'success'|'error'` for richer UI; avoid multiple booleans that can drift.
+6. Computed Selectors: Name as `XComputed` or just semantic (e.g. `filteredItems`) using `computed(() => ...)` inside `withComputed`; never cause side-effects in a computed.
+7. Resource Factory Pattern: For remote data needed in multiple components, create a factory function returning an object with `value`, `isLoading`, `error` signals plus a `reload()` method; see remission `resources/` directory.
+
+Store Lifecycle Hooks:
+
+- Use `withHooks({ onInit() { ... }, onDestroy() { ... } })` for restoration, websockets, or timers. Pair cleanups explicitly.
+
+Persistence Feature (`withStorage`):
+
+- Implementation: Debounced `storeState` rxMethod listens to any state change, saves hashed user‑scoped key (see `hash.utils.ts`). On init it calls `restoreState()`.
+- Extending: If you need to blacklist transient fields from persistence, add a method wrapping `getState` and remove keys before `storage.set` (extend feature locally rather than editing shared code unless broadly needed).
+
+Typical Store Template:
+
+```ts
+// feature-x.store.ts
+import {
+  signalStore,
+  withState,
+  withComputed,
+  withMethods,
+  withHooks,
+} from '@ngrx/signals';
+import { rxMethod } from '@ngrx/signals/rxjs-interop';
+import { debounceTime, switchMap, tap, catchError, of } from 'rxjs';
+import { withStorage } from '@isa/core/storage';
+import { logger } from '@isa/core/logging';
+
+interface FeatureXState {
+  items: ReadonlyArray<Item>;
+  query: string;
+  loading: boolean;
+  error?: string;
+}
+
+const initialState: FeatureXState = { items: [], query: '', loading: false };
+
+export const FeatureXStore = signalStore(
+  withState(initialState),
+  withProps((store, logger = logger(() => ({ store: 'FeatureX' }))) => ({
+    _logger: logger,
+  })),
+  withComputed(({ items, query }) => ({
+    filtered: computed(() => items().filter((i) => i.name.includes(query()))),
+    hasError: computed(() => !!query() && !items().length),
+  })),
+  withMethods((store) => ({
+    setQuery: (q: string) => patchState(store, { query: q }),
+    // rxMethod side effect to load items
+    loadItems: rxMethod<string | void>(
+      pipe(
+        debounceTime(150),
+        tap(() => patchState(store, { loading: true, error: undefined })),
+        switchMap(() =>
+          fetchItems(store.query()).pipe(
+            tap((items) => patchState(store, { items, loading: false })),
+            catchError((err) => {
+              store._logger.error('Load failed', err as Error, () => ({
+                query: store.query(),
+              }));
+              patchState(store, {
+                loading: false,
+                error: (err as Error).message,
+              });
+              return of([]);
+            }),
+          ),
+        ),
+      ),
+    ),
+  })),
+  withHooks((store) => ({
+    onInit() {
+      store.loadItems();
+    },
+  })),
+  withStorage('feature-x', LocalStorageProvider),
+);
+```
+
+Testing Signal Stores (Vitest or Jest):
+
+- Use `runInInjectionContext(TestBed.inject(Injector), () => FeatureXStore)` or instantiate via exported factory if provided.
+- For async rxMethod flows, flush microtasks (`await vi.runAllTimersAsync()` if timers used) or rely on returned observable completion when you subscribe inside the test harness.
+- Snapshot only primitive slices (avoid full object snapshots with volatile ordering).
+
+Migration Tips:
+
+- Converting legacy NgRx reducers: Start by lifting static initial state + selectors into `withState` + `withComputed`; replace effects with `rxMethod` maintaining cancellation semantics (`switchMap` mirrors effect flattening strategy).
+- Keep action names only if externally observed (analytics, logging). Otherwise remove ceremony—call store methods directly.
+
+Anti-Patterns to Avoid:
+
+- Writing to signals inside a computed or inside another signal setter (causes cascading updates).
+- Storing large unnormalized arrays and then repeatedly filtering/sorting in multiple components—centralize that in computed selectors.
+- Persisting secrets or PII directly; hash keys already user-scoped but content still plain—sanitize if needed.
+- Returning raw subscriptions from store methods; expose signals or idempotent methods only.
+
+#### 7.b Prefer Signals over Observables (Practical Rules)
+
+Default to signals for all in-memory UI & derived state; keep Observables only at I/O edges.
+
+Use Observables for:
+
+- HTTP / WebSocket / SignalR streams at the boundary.
+- Timer / interval / external event sources.
+- Interop with legacy NgRx store pieces not yet migrated.
+
+Immediately convert inbound Observables to signals:
+
+```ts
+// Legacy service returning Observable<Item[]>
+items$ = http.get<Item[]>(url);
+// New pattern
+const items = toSignal(http.get<Item[]>(url), { initialValue: [] });
+```
+
+Expose signals from stores & services:
+
+```ts
+// BAD (forces template async pipe + subscription mgmt)
+getItems(): Observable<Item[]> { return this.http.get(...); }
+
+// GOOD
+items = toSignal(this.http.get<Item[]>(url), { initialValue: [] });
+```
+
+Bridge when needed:
+
+```ts
+// Signal -> Observable (rare):
+const queryChanges$ = fromSignal(query, { requireSync: true });
+
+// Observable -> Signal (preferred):
+const data = toSignal(data$, { initialValue: undefined });
+```
+
+Side-effects: never subscribe manually—wrap in `rxMethod` (cancels stale work via `switchMap`).
+
+```ts
+loadData: rxMethod<void>(
+  pipe(
+    switchMap(() =>
+      this.api.fetch().pipe(tap((r) => patchState(store, { data: r }))),
+    ),
+  ),
+);
+```
+
+Template usage: reference signals directly (`{{ item.name }}`) or in control flow; no `| async` needed.
+
+Replacing combineLatest / map chains:
+
+```ts
+// Before (Observable)
+vm$ = combineLatest([a$, b$]).pipe(map(([a, b]) => buildVm(a, b)));
+
+// After (Signals)
+const vm = computed(() => buildVm(a(), b()));
+```
+
+Debounce / throttle user input:
+Keep raw form value as a signal; create an rxMethod for debounced fetch instead of debouncing inside a computed.
+
+```ts
+search = signal('');
+runSearch: rxMethod<string>(
+  pipe(
+    debounceTime(300),
+    switchMap((term) =>
+      this.api
+        .search(term)
+        .pipe(tap((results) => patchState(store, { results }))),
+    ),
+  ),
+);
+effect(() => {
+  runSearch(this.search());
+});
+```
+
+Avoid converting a signal back to an Observable just to use a single RxJS operator; prefer inline signal `computed` or small helper.
+
+Migration heuristic:
+
+1. Identify component `foo$` fields used only in template -> convert to signal via `toSignal`.
+2. Collapse chains of `combineLatest` + `map` into `computed`.
+3. Replace imperative `subscribe` side-effects with `rxMethod` + `patchState`.
+4. Add persistence last via `withStorage` if state must survive reload.
+
+Performance tip: heavy derived computations (sorting large arrays) belong in a memoized `computed`; if expensive & infrequently needed, gate behind another signal flag.
+
+### 8. Scanner Integration (Scandit)
+
+- Barcode scanning encapsulated in `@isa/shared/scanner` (`scanner.service.ts`). Use provided injection tokens for license & defaults (override via DI if needed). Service auto-configures once; `ready` signal triggers `configure()` lazily.
+- Always catch and log errors with proper context; platform gating throws `PlatformNotSupportedError` which is downgraded to warn.
+
+### 9. Styling
+
+- Tailwind with custom semantic tokens (`tailwind.config.js`). Prefer design tokens like `text-isa-neutral-700`, spacing utilities with custom `px-*` scales rather than ad‑hoc raw values.
+- Global overlays rely on CDK classes; retain `@angular/cdk/overlay-prebuilt.css` in style arrays when creating new entrypoints or Storybook stories.
+
+### 10. Library Conventions
+
+- File naming: kebab-case; feature first then type (e.g. `return-receipt-list.component.ts`).
+- Provide public API via each lib `src/index.ts`. Export only stable symbols; keep internal utilities in subfolders not re-exported.
+- Add `project.json` with `test` & `lint` targets; for new Vitest libs include `vite.config.mts` and adjust `tsconfig.spec.json` references to vitest types.
+
+### 11. Adding / Modifying Tests
+
+- For Jest libs: standard `*.spec.ts` with `TestBed`. Spectator may appear in legacy code—do not introduce Spectator in new tests; use Angular Testing Utilities.
+- For Vitest libs: ensure `vite.config.mts` includes `setupFiles`. Use `describe/it` from `vitest` and Angular TestBed (see remission resource spec for pattern of using `runInInjectionContext`).
+- Prefer resource-style factories returning signals for async state (pattern in `createSupplierResource`).
+
+### 12. Performance & Safety
+
+- Logging: rely on lazy context function; avoid `JSON.stringify()` unless behind a dev guard.
+- Storage: hashing keys (see `hash.utils.ts`) ensures stable key space; do not bypass if you need consistent per-user scoping.
+- Scanner overlay: always clean up overlay + event listeners (follow existing `open` implementation for pattern).
+
+### 13. CI / Coverage / Artifacts
+
+- JUnit XML placed in `testresults/` (Jest configured with `jest-junit`). Keep filename stability for pipeline consumption; do not rename those outputs.
+- Coverage output under `coverage/libs/...`; respect Nx caching—avoid side effects outside project roots.
+
+### 14. When Unsure
+
+- Search existing domain folder for analogous implementation (e.g. new feature under remission: inspect sibling feature libs for structure).
+- Preserve existing DI token patterns instead of introducing new global singletons.
+
+### 15. Quick Examples
+
+```ts
+// New feature logger usage
+const log = logger(() => ({ feature: 'ReturnReceipt', action: 'init' }));
+log.info('Mount');
+
+// Persisting a signal store slice
+export const FeatureStore = signalStore(
+  withState(initState),
+  withStorage('return:filters', LocalStorageProvider),
+);
+
+// Fetch config value safely
+const apiBase = inject(Config).get('api.baseUrl', z.string().url());
+```

+
+# Plan Mode
+
+You are now operating in **Plan Mode** - a research and planning phase that ensures thorough analysis before implementation. Plan mode is **ALWAYS ACTIVE** when using this prompt. You must follow these strict guidelines for every request:
+
+## Phase 1: Research & Analysis (MANDATORY)
+
+### ALLOWED Operations:
+
+- ✅ Read files using Read, Glob, Grep tools
+- ✅ Search documentation and codebases
+- ✅ Analyze existing patterns and structures
+- ✅ Use WebFetch for documentation research
+- ✅ List and explore project structure
+- ✅ Use Nx/Angular/Context7 MCP tools for workspace analysis
+- ✅ Review dependencies and configurations
+
+### FORBIDDEN Operations:
+
+- ❌ **NEVER** create, edit, or modify any files
+- ❌ **NEVER** run commands that change system state
+- ❌ **NEVER** make commits or push changes
+- ❌ **NEVER** install packages or modify configurations
+- ❌ **NEVER** run build/test commands during planning
+
+## Phase 2: Plan Presentation (REQUIRED FORMAT)
+
+After thorough research, present your plan using this exact structure:
+
+```markdown

+
+## Phase 3: Await Approval
+
+After presenting the plan:
+
+1. **STOP** all implementation activities
+2. **WAIT** for explicit user approval
+3. **DO NOT** proceed with any file changes
+4. **RESPOND** to questions or plan modifications
+5. **EXIT PLAN MODE** only when user explicitly says "execute", "implement", "go ahead", "approved", or similar approval language
+
+## Phase 4: Implementation (After Exiting Plan Mode)
+
+Once the user explicitly approves and you exit plan mode:
+
+1. **PLAN MODE IS NOW DISABLED** - you can proceed with normal implementation
+2. Use TodoWrite to create implementation todos
+3. Follow the plan step-by-step
+4. Update todos as you progress
+5. Run tests and lint checks as specified
+6. Provide progress updates
+
+## Key Behavioral Rules
+
+### Research Thoroughly
+
+- Spend significant time understanding the codebase
+- Look for existing patterns to follow
+- Identify all dependencies and integration points
+- Consider edge cases and error scenarios
+
+### Be Comprehensive
+
+- Plans should be detailed enough for another developer to implement
+- Include all necessary file changes
+- Consider testing, documentation, and deployment
+- Address potential conflicts or breaking changes
+
+### Show Your Work
+
+- Explain reasoning behind architectural decisions
+- Reference existing code patterns when applicable
+- Cite documentation or best practices
+- Provide alternatives when multiple approaches exist
+
+### Safety First
+
+- Never make changes during planning phase
+- Always wait for explicit approval
+- Flag potentially risky changes
+- Suggest incremental implementation when complex
+
+## Example Interactions
+
+### Good Plan Mode Behavior:
+
+```
+User: "Add a dark mode toggle to the settings page"
+Assistant: I'll research the current theming system and create a comprehensive plan for implementing dark mode.
+
+[Extensive research using Read, Grep, Glob tools]
+
+## 📋 Implementation Plan
+[Follows complete format above]
+
+Ready to proceed? Please approve this plan before I begin implementation.
+```
+
+### What NOT to do:
+
+```
+User: "Add a dark mode toggle"
+Assistant: I'll add that right away!
+[Immediately starts editing files - WRONG!]
+```
+
+# <<<<<<< HEAD

+# General Guidelines for working with Nx
+
+- When running tasks (for example build, lint, test, e2e, etc.), always prefer running the task through `nx` (i.e. `nx run`, `nx run-many`, `nx affected`) instead of using the underlying tooling directly
+- You have access to the Nx MCP server and its tools, use them to help the user
+- When answering questions about the repository, use the `nx_workspace` tool first to gain an understanding of the workspace architecture where applicable.
+- When working in individual projects, use the `nx_project_details` mcp tool to analyze and understand the specific project structure and dependencies
+- For questions around nx configuration, best practices or if you're unsure, use the `nx_docs` tool to get relevant, up-to-date docs. Always use this instead of assuming things about nx configuration
+- If the user needs help with an Nx configuration or project graph error, use the `nx_workspace` tool to get any errors

+# CLAUDE.md
+
+This file contains meta-instructions for how Claude should work with the ISA-Frontend codebase.
+
+## 🔴 CRITICAL: Mandatory Agent Usage
+
+**You MUST use these subagents for ALL research and knowledge management tasks:**
+
+- **`docs-researcher`**: For ALL documentation (packages, libraries, READMEs)
+- **`docs-researcher-advanced`**: Auto-escalate when docs-researcher fails
+- **`Explore`**: For ALL code pattern searches and multi-file analysis
+
+**Violations of this rule degrade performance and context quality. NO EXCEPTIONS.**
+
+## Communication Guidelines
+
+**Keep answers concise and focused:**
+
+- Provide direct, actionable responses without unnecessary elaboration
+- Skip verbose explanations unless specifically requested
+- Focus on what the user needs to know, not everything you know
+- Use bullet points and structured formatting for clarity
+- Only provide detailed explanations when complexity requires it
+
+## Researching and Investigating the Codebase
+
+**🔴 MANDATORY: You MUST use subagents for research. Direct file reading/searching.**
+
+### Required Agent Usage
+
+| Task Type                         | Required Agent     | Escalation Path                           |
+| --------------------------------- | ------------------ | ----------------------------------------- |
+| **Package/Library Documentation** | `docs-researcher`  | → `docs-researcher-advanced` if not found |
+| **Internal Library READMEs**      | `docs-researcher`  | Keep context clean                        |
+| **Code Pattern Search**           | `Explore`          | Set thoroughness level                    |
+| **Implementation Analysis**       | `Explore`          | Multiple file analysis                    |
+| **Single Specific File**          | Read tool directly | No agent needed                           |
+
+### Documentation Research System (Two-Tier)
+
+1. **ALWAYS start with `docs-researcher`** (Haiku, 30-120s) for any documentation need
+2. **Auto-escalate to `docs-researcher-advanced`** (Sonnet, 2-7min) when:
+   - Documentation not found
+   - Conflicting sources
+   - Need code inference
+   - Complex architectural questions
+
+### Enforcement Examples
+
+```
+❌ WRONG: Read libs/ui/buttons/README.md
+✅ RIGHT: Task → docs-researcher → "Find documentation for @isa/ui/buttons"
+
+❌ WRONG: Grep for "signalStore" patterns
+✅ RIGHT: Task → Explore → "Find all signalStore implementations"
+
+❌ WRONG: WebSearch for Zod documentation
+✅ RIGHT: Task → docs-researcher → "Find Zod validation documentation"
+```
+
+**Remember: Using subagents is NOT optional - it's mandatory for maintaining context efficiency and search quality.**

+# Purchase Options Modal
+
+The Purchase Options Modal allows users to select how they want to receive their items (delivery, pickup, in-store, download) during the checkout process.
+
+## Overview
+
+This modal handles the complete purchase option selection flow including:
+- Fetching availability for each purchase option
+- Validating if items can be added to the shopping cart
+- Managing item quantities and prices
+- Supporting reward redemption flows
+
+## Features
+
+### Core Functionality
+- **Multiple Purchase Options**: Delivery, B2B Delivery, Digital Delivery, Pickup, In-Store, Download
+- **Availability Checking**: Real-time availability checks for each option
+- **Branch Selection**: Pick branches for pickup and in-store options
+- **Price Management**: Handle pricing, VAT, and manual price adjustments
+- **Reward Redemption**: Support for redeeming loyalty points
+
+### Advanced Features
+- **Disabled Purchase Options**: Prevent specific options from being available (skips API calls)
+- **Hide Disabled Options**: Toggle visibility of disabled options (show grayed out or hide completely)
+- **Pre-selection**: Pre-select a specific purchase option on open
+- **Single Option Mode**: Show only one specific purchase option
+
+## Usage
+
+### Basic Usage
+
+```typescript
+import { PurchaseOptionsModalService } from '@modal/purchase-options';
+
+constructor(private purchaseOptionsModal: PurchaseOptionsModalService) {}
+
+async openModal() {
+  const modalRef = await this.purchaseOptionsModal.open({
+    tabId: 123,
+    shoppingCartId: 456,
+    type: 'add', // or 'update'
+    items: [/* array of items */],
+  });
+
+  const result = await firstValueFrom(modalRef.afterClosed$);
+}
+```
+
+### Disabling Purchase Options
+
+Prevent specific options from being available. The modal will **not make API calls** for disabled options.
+
+```typescript
+const modalRef = await this.purchaseOptionsModal.open({
+  tabId: 123,
+  shoppingCartId: 456,
+  type: 'add',
+  items: [item1, item2],
+  disabledPurchaseOptions: ['b2b-delivery'], // Disable B2B delivery
+});
+```
+
+### Hide vs Show Disabled Options
+
+Control whether disabled options are hidden or shown with a disabled visual state:
+
+**Hide Disabled Options (default)**
+```typescript
+const modalRef = await this.purchaseOptionsModal.open({
+  tabId: 123,
+  shoppingCartId: 456,
+  type: 'add',
+  items: [item],
+  disabledPurchaseOptions: ['b2b-delivery'],
+  hideDisabledPurchaseOptions: true, // Default - option not visible
+});
+```
+
+**Show Disabled Options (grayed out)**
+```typescript
+const modalRef = await this.purchaseOptionsModal.open({
+  tabId: 123,
+  shoppingCartId: 456,
+  type: 'add',
+  items: [item],
+  disabledPurchaseOptions: ['b2b-delivery'],
+  hideDisabledPurchaseOptions: false, // Show disabled with visual indicator
+});
+```
+
+### Pre-selecting an Option
+
+```typescript
+const modalRef = await this.purchaseOptionsModal.open({
+  tabId: 123,
+  shoppingCartId: 456,
+  type: 'add',
+  items: [item],
+  preSelectOption: {
+    option: 'in-store',
+    showOptionOnly: false, // Optional: show only this option
+  },
+});
+```
+
+### Reward Redemption Flow
+
+```typescript
+const modalRef = await this.purchaseOptionsModal.open({
+  tabId: 123,
+  shoppingCartId: 456,
+  type: 'add',
+  items: [rewardItem],
+  useRedemptionPoints: true,
+  preSelectOption: { option: 'in-store' },
+  disabledPurchaseOptions: ['b2b-delivery'], // Common for rewards
+});
+```
+
+## API Reference
+
+### PurchaseOptionsModalData
+
+```typescript
+interface PurchaseOptionsModalData {
+  /** Tab ID for context */
+  tabId: number;
+
+  /** Shopping cart ID to add/update items */
+  shoppingCartId: number;
+
+  /** Action type: 'add' = new items, 'update' = existing items */
+  type: 'add' | 'update';
+
+  /** Enable redemption points mode */
+  useRedemptionPoints?: boolean;
+
+  /** Items to show in the modal */
+  items: Array<ItemDTO | ShoppingCartItemDTO>;
+
+  /** Pre-configured pickup branch */
+  pickupBranch?: BranchDTO;
+
+  /** Pre-configured in-store branch */
+  inStoreBranch?: BranchDTO;
+
+  /** Pre-select a specific purchase option */
+  preSelectOption?: {
+    option: PurchaseOption;
+    showOptionOnly?: boolean;
+  };
+
+  /** Purchase options to disable (no API calls) */
+  disabledPurchaseOptions?: PurchaseOption[];
+
+  /** Hide disabled options (true) or show as grayed out (false). Default: true */
+  hideDisabledPurchaseOptions?: boolean;
+}
+```
+
+### PurchaseOption Type
+
+```typescript
+type PurchaseOption =
+  | 'delivery'        // Standard delivery
+  | 'dig-delivery'    // Digital delivery
+  | 'b2b-delivery'    // B2B delivery
+  | 'pickup'          // Pickup at branch
+  | 'in-store'        // Reserve in store
+  | 'download'        // Digital download
+  | 'catalog';        // Catalog availability
+```

+
+### State Management
+
+The modal uses NgRx ComponentStore for state management:
+- **Availability Loading**: Parallel API calls for each enabled option
+- **Can Add Validation**: Check if items can be added to cart
+- **Item Selection**: Track selected items for batch operations
+- **Branch Management**: Handle branch selection for pickup/in-store
+
+### Disabled Options Flow
+
+1. **Configuration**: `disabledPurchaseOptions` array passed to modal
+2. **State**: Stored in store via `initialize()` method
+3. **Availability Loading**: `isOptionDisabled()` check skips API calls
+4. **UI Rendering**:
+   - If `hideDisabledPurchaseOptions: true` → not rendered
+   - If `hideDisabledPurchaseOptions: false` → rendered with `.disabled` class
+5. **Click Prevention**: Disabled tiles prevent click action
+
+## Common Use Cases
+
+### 1. Regular Checkout
+```typescript
+// Show all options
+await modalService.open({
+  tabId: processId,
+  shoppingCartId: cartId,
+  type: 'add',
+  items: catalogItems,
+});
+```
+
+### 2. Reward Redemption
+```typescript
+// Pre-select in-store, disable B2B
+await modalService.open({
+  tabId: processId,
+  shoppingCartId: rewardCartId,
+  type: 'add',
+  items: rewardItems,
+  useRedemptionPoints: true,
+  preSelectOption: { option: 'in-store' },
+  disabledPurchaseOptions: ['b2b-delivery'],
+});
+```
+
+### 3. Update Existing Item
+```typescript
+// Allow user to change delivery option
+await modalService.open({
+  tabId: processId,
+  shoppingCartId: cartId,
+  type: 'update',
+  items: [existingCartItem],
+});
+```
+
+### 4. Gift Cards (In-Store Only)
+```typescript
+// Show only in-store and delivery
+await modalService.open({
+  tabId: processId,
+  shoppingCartId: cartId,
+  type: 'add',
+  items: [giftCardItem],
+  disabledPurchaseOptions: ['pickup', 'b2b-delivery'],
+});
+```
+
+## Testing
+
+### Running Tests
+```bash
+# Run all tests for the app
+npx nx test isa-app --skip-nx-cache
+```
+
+### Testing Disabled Options
+When testing the disabled options feature:
+1. Verify no API calls are made for disabled options
+2. Check UI rendering based on `hideDisabledPurchaseOptions` flag
+3. Ensure click events are prevented on disabled tiles
+4. Validate backward compatibility (defaults work correctly)
+
+## Migration Notes
+
+### From `hidePurchaseOptions` to `disabledPurchaseOptions`
+The field was renamed for clarity:
+- **Old**: `hidePurchaseOptions` (ambiguous - hides from UI)
+- **New**: `disabledPurchaseOptions` (clear - disabled functionality, may or may not be hidden)
+
+This is a **breaking change** if you were using `hidePurchaseOptions`. Update all usages:
+
+```typescript
+// Before
+hidePurchaseOptions: ['b2b-delivery']
+
+// After
+disabledPurchaseOptions: ['b2b-delivery']
+```
+
+## Troubleshooting
+
+### Problem: Disabled option still making API calls
+**Solution**: Ensure the option is in the `disabledPurchaseOptions` array and spelled correctly.
+
+### Problem: Disabled option not showing even with `hideDisabledPurchaseOptions: false`
+**Solution**: Check that `showOption()` logic and availability checks are working correctly.
+
