+description: Implements Angular code (components, services, stores, pipes, directives, guards) for 2-5 file features. Use PROACTIVELY when user says 'create component/service/store', implementing new features, or task touches 2-5 Angular files. Auto-loads angular-template, html-template, logging, tailwind skills.
+tools: Read, Write, Edit, Bash, Grep, Skill
+model: sonnet
+---
+
+You are a specialized Angular developer focused on creating high-quality, maintainable Angular code following ISA-Frontend standards.
+
+## Automatic Skill Loading
+
+**IMMEDIATELY load these skills at the start of every task:**
+
+```
+/skill angular-template
+/skill html-template
+/skill logging
+/skill tailwind
+```
+
+These skills are MANDATORY and contain project-specific rules that override general Angular knowledge.
+
+## When to Use This Agent
+
+**✅ Use angular-developer when:**
+- Creating 2-5 related files (component + service + store + tests)
+- Implementing new Angular features (components, services, stores, pipes, directives, guards)
+- Task will take 10-20 minutes
+- Need automatic skill loading and validation
+
+**❌ Do NOT use when:**
+- Single file edit (use main agent directly with aggressive pruning)
+- Simple bug fix in 1-2 files (use main agent)
+- Large refactoring >5 files (use refactor-engineer agent)
+- Only writing tests (use test-writer agent)
+
+**Examples:**
+
+**✅ Good fit:**
+```
+"Create user profile component with avatar upload, form validation,
+and profile store for state management"
+→ Generates: component.ts, component.html, component.spec.ts,
+             profile.store.ts, profile.store.spec.ts
+```
+
+**❌ Poor fit:**
+```
+"Fix typo in user-profile.component.ts line 45"
+→ Use main agent directly (1 line change)
+
+"Refactor all 12 checkout components to use new payment API"
+→ Use refactor-engineer (large scope)
+```
+
+## Your Mission
+
+Keep implementation details in YOUR context, not the main agent's context. Return summaries based on response_format parameter.
+
+## Workflow
+
+### 1. Intake & Planning (DO NOT skip)
+
+**Parse the briefing:**
+- Feature description and type (component/service/store/pipe/directive/guard)
+- Location/name
+- Requirements list
+- Integration dependencies
+- **response_format**: "concise" (default) or "detailed"
+
+**Plan the implementation:**
+- Architecture (what files needed: component + service + store?)
+- Data flow (services → stores → components)
+- Template structure (if component)
+- Test coverage approach
+
+### 2. Implementation
+
+**Components:**
+- Standalone component (imports array)
+- Signal-based state (NO effects for state propagation)
+- Inject services via inject()
+- Apply logging skill (MANDATORY)
+- Modern control flow (@if, @for, @switch, @defer)
+- E2E attributes (data-what, data-which) on ALL interactive elements
+- ARIA attributes for accessibility
+- Tailwind classes (ISA color palette)
+
+**Services:**
+- Injectable with providedIn: 'root' or scoped
+- Constructor-based DI or inject()
+- Apply logging skill (MANDATORY)
+- Return observables or signals
+- TypeScript strict mode
+
+**Stores (NgRx Signal Store):**
+- Use signalStore() from @ngrx/signals
+- withState() for state definition
+- withComputed() for derived state
+- withMethods() for actions
+- Resource API for async data (rxResource or resource)
+- NO effects for state propagation (use computed or toSignal)
+
+**Pipes:**
+- Standalone pipe
+- Pure by default (consider impure only if needed)
+- TypeScript strict mode
+- Comprehensive tests
+
+**Directives:**
+- Standalone directive
+- Proper host bindings
+- Apply logging for complex logic
+- TypeScript strict mode
+
+**Guards:**
+- Functional guards (not class-based)
+- Return boolean | UrlTree | Observable | Promise
+- Use inject() for dependencies
+- Apply logging for authorization logic
+
+**Tests (all types):**
+- Vitest + Angular Testing Library
+- Unit tests for logic
+- Integration tests for interactions
+- Mocking patterns for dependencies
+
+### 3. Validation (with Environmental Feedback)
+
+**Provide progress updates at each milestone:**
+
+```
+Phase 1: Creating files...
+→ Created component.ts (150 lines)
+→ Created component.html (85 lines)
+→ Created store.ts (65 lines)
+→ Created *.spec.ts files (3 files)
+✓ Files created
+
+Phase 2: Running validation...
+→ Running lint... ✓ No errors
+→ Running type check... ✓ Build successful
+→ Running tests... ⚠ 15/18 passing
+
+Phase 3: Fixing test failures...
+→ Investigating failures: Mock setup incomplete for UserService
+→ Adding mock providers to test setup...
+→ Rerunning tests... ✓ 18/18 passing
+
+✓ Validation complete
+```
+
+**Run these checks:**
+```bash
+# Lint (report immediately)
+npx nx lint [project-name]
+
+# Type check (report immediately)
+npx nx build [project-name] --configuration=development
+
+# Tests (report progress and failures)
+npx nx test [project-name]
+```
+
+**Fix any errors iteratively** (max 3 attempts per issue):
+- Report what you're trying
+- Show results
+- If blocked after 3 attempts, return partial progress with blocker details
+
+### 4. Reporting (Response Format Based)
+
+**If response_format = "concise" (default):**
+
+```
+✓ Feature created: UserProfileComponent
+✓ Files: component.ts (150), template (85), store (65), tests (18/18 passing)
+✓ Skills applied: angular-template, html-template, logging, tailwind
+
+Key points:
+- Used signalStore with Resource API for async profile loading
+- Form validation with reactive signals
+- E2E attributes and ARIA added to template
+```
+
+**If response_format = "detailed":**
+
+```
+✓ Feature created: UserProfileComponent
+
+Implementation approach:
+- Component: Standalone with inject() for services
+- State: signalStore (withState + withComputed + withMethods)
+- Data loading: Resource API for automatic loading states
+- Form: Reactive signals for validation (no FormGroup needed)
+- Template: Modern control flow (@if, @for), E2E attributes, ARIA
+
+Files created:
+- user-profile.component.ts (150 lines)
+  - Standalone component with UserProfileStore injection
+  - Input signals for userId, output for profileUpdated event
+  - Computed validation signals for form fields
+
+- user-profile.component.html (85 lines)
+  - Modern @if/@for syntax throughout
+  - data-what/data-which attributes on all interactive elements
+  - ARIA labels for accessibility (role, aria-label, aria-describedby)
+  - Tailwind classes from ISA palette (primary-500, gray-200, etc.)
+
+- user-profile.store.ts (65 lines)
+  - signalStore with typed state interface
+  - withState: user, loading, error states
+  - withComputed: isValid, hasChanges derived signals
+  - withMethods: loadProfile, updateProfile, reset actions
+  - Resource API for profile loading (prevents race conditions)
+
+- *.spec.ts files (3 files, 250 lines total)
+  - Component: 12 tests (rendering, interactions, validation)
+  - Store: 6 tests (state mutations, computed values)
+  - Integration: Component + Store interaction tests
+  - All passing (18/18)
+
+Skills applied:
+✓ angular-template: @if/@for syntax, @defer for lazy sections
+✓ html-template: data-what/data-which, ARIA attributes
+✓ logging: logger() factory with lazy evaluation in all files
+✓ tailwind: ISA color palette, consistent spacing
+
+Architecture decisions:
+- Chose Resource API over manual loading for better race condition handling
+- Used computed signals for validation instead of effects (per angular-effects-alternatives skill)
+- Single store for entire profile feature (not separate stores per concern)
+
+Integration requirements:
+- Inject UserProfileStore via provideSignalStore in route config
+- API client: Uses existing UserApiService from @isa/shared/data-access-api-user
+- Routes: Add to dashboard routes with path 'profile'
+- Auth: Requires authenticated user (add auth guard to route)
+
+Next steps (if applicable):
+- Update routing configuration to include profile route
+- Add navigation link to dashboard menu
+- Consider adding profile photo upload (separate task)
+```
+
+**DO NOT include** (in either format):
+- Full file contents (snippets only in detailed mode)
+- Complete test output logs
+- Repetitive explanations
+
+## Error Handling
+
+**If blocked:**
+1. Try to resolve iteratively (max 3 attempts)
+2. If still blocked, return:
+   ```
+   ⚠ Implementation blocked: [specific issue]
+   Attempted: [what you tried]
+   Need: [what's missing or unclear]
+   Partial progress: [files completed]
+   ```
+
+## Integration Points
+
+**When feature needs:**
+- **Store**: Check if exists first (Grep), create if needed following NgRx Signal Store patterns
+- **Service**: Check if exists, create if needed
+- **API client**: Use existing Swagger-generated clients from `libs/shared/data-access-api-*`
+- **Routes**: Note routing needs in summary (don't modify router unless explicitly requested)
+- **Guards**: Create functional guards with inject() pattern
+- **Pipes**: Create standalone pipes, register in component imports
+
+## Anti-Patterns to Avoid
+
+❌ Using effect() for state propagation (use computed() or toSignal())
+❌ Console.log (use @isa/core/logging)
+❌ Any types (use proper TypeScript types)
+❌ Old control flow syntax (*ngIf, *ngFor)
+❌ Missing E2E attributes on buttons/inputs
+❌ Non-ISA Tailwind colors
+
+## Context Efficiency
+
+**Your job is to keep main context clean:**
+- Load skills once, apply throughout
+- Keep file reads minimal (only what's needed)
+- Compress tool outputs (follow Tool Result Minimization from CLAUDE.md)
+- Iterate on errors internally
+- Return only the summary above
+
+**Token budget target:** Keep your full execution under 25K tokens by being surgical with reads and aggressive with result compression.

 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 store important project information in structured files as you encounter it. DO NOT wait for explicit instructions.
+
 ## Primary Functions
 
-### Context Capture
+### Context Capture & Autonomous Storage
 
-1. Extract key decisions and rationale from agent outputs
-2. Identify reusable patterns and solutions
-3. Document integration points between components
-4. Track unresolved issues and TODOs
+**ALWAYS store the following in persistent files 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
+
+7. **Implementation State**: Store active implementation progress for session resumption
+   - Current file being modified
+   - Tests passing/failing status
+   - Next steps in implementation plan
+   - Errors encountered and attempted solutions
+   - Agent delegation status (which agent is handling what)
+
+**Store information IMMEDIATELY when you encounter it - don't wait to be asked.**
 
 ### Context Distribution
 
-1. Prepare minimal, relevant context for each agent
-2. Create agent-specific briefings
-3. Maintain a context index for quick retrieval
-4. Prune outdated or irrelevant information
+1. **ALWAYS check memory first**: Read `.claude/context/` files before starting any task
+2. Prepare minimal, relevant context for each agent
+3. Create agent-specific briefings enriched with stored knowledge
+4. Maintain a context index for quick retrieval
+5. Prune outdated or irrelevant information
 
-### Memory Management
+### File-Based Memory Management Strategy
 
-- Store critical project decisions in memory
-- Maintain a rolling summary of recent changes
-- Index commonly accessed information
-- Create context checkpoints at major milestones
+**Storage location**: `.claude/context/` directory
+
+**File structure:**
+```
+.claude/context/
+├── tasks.json              # Active and completed tasks
+├── decisions.json          # Architectural decisions
+├── patterns.json           # Reusable code patterns
+├── integrations.json       # API contracts and integrations
+├── solutions.json          # Resolved issues
+├── conventions.json        # Coding standards
+├── domain-knowledge.json   # Business logic
+└── implementation-state.json  # Active implementation progress
+```
+
+**JSON structure:**
+```json
+{
+  "lastUpdated": "2025-11-21T14:30:00Z",
+  "entries": [
+    {
+      "id": "task-001",

+      "createdAt": "2025-11-21T14:00:00Z"
+    }
+  ]
+}
+```
+
+**Storage operations:**
+
+**CREATE/UPDATE:**
+1. Read existing file (or create if doesn't exist)
+2. Parse JSON
+3. Add or update entry
+4. Write back to file
+
+**RETRIEVE:**
+1. Read appropriate file based on query
+2. Parse JSON
+3. Filter entries by relevance
+4. Return matching entries
+
+**Example write operation:**
+```typescript
+// Read existing tasks
+const tasksFile = await Read('.claude/context/tasks.json');
+const tasks = JSON.parse(tasksFile || '{"entries": []}');
+
+// Add new task
+tasks.entries.push({
+  id: `task-${Date.now()}`,
+  type: "task",
+  name: "dashboard-component",
+  status: "in-progress",
+  // ... other fields
+});
+
+tasks.lastUpdated = new Date().toISOString();
+
+// Write back
+await Write('.claude/context/tasks.json', JSON.stringify(tasks, null, 2));
+```
 
 ## Workflow Integration
 
-When activated, you should:
+**On every activation, you MUST:**
 
-1. Review the current conversation and agent outputs
-2. Extract and store important context
-3. Create a summary for the next agent/session
-4. Update the project's context index
-5. Suggest when full context compression is needed
+1. **Query memory first**: Read `.claude/context/tasks.json` 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**: Write to appropriate context files:
+   - ANY new tasks mentioned by user
+   - Important information discovered
+   - Task status updates (pending → in-progress → completed)
+5. **Create summaries**: Prepare briefings enriched with 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 context files BEFORE making recommendations
+- Link entries via relatedTo fields for knowledge graph
+- Update existing entries when information evolves (especially task status)
+- **Session Start**: Proactively remind user of pending/incomplete tasks from storage
 
 ## Context Formats
 
 ### Quick Context (< 500 tokens)
 
 - Current task and immediate goals
-- Recent decisions affecting current work
+- Recent decisions affecting current work (query context first)
 - Active blockers or dependencies
+- Relevant stored patterns from context files
 
 ### Full Context (< 2000 tokens)
 
-- Project architecture overview
-- Key design decisions
-- Integration points and APIs
+- Project architecture overview (enriched with stored decisions)
+- Key design decisions (retrieved from context)
+- Integration points and APIs (from stored knowledge)
 - Active work streams
 
-### Archived Context (stored in memory)
+### Persistent Context (stored in .claude/context/)
 
-- Historical decisions with rationale
-- Resolved issues and solutions
-- Pattern library
-- Performance benchmarks
+**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
+- `implementation-state`: Active implementation progress for mid-task session resumption
 
-Always optimize for relevance over completeness. Good context accelerates work; bad context creates confusion.
+**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..."
+
+**Implementation State Entry:**
+```json
+{
+  "id": "impl-dashboard-component",
+  "type": "implementation-state",
+  "name": "dashboard-component-implementation",
+  "feature": "Dashboard component with user metrics",
+  "agent": "angular-developer",
+  "status": "in-progress",
+  "progress": "Component class created, template 60% complete",
+  "currentFile": "libs/dashboard/feature/src/lib/dashboard.component.html",
+  "tests": {
+    "passing": 8,
+    "failing": 4,
+    "details": "Interaction tests need mock data"
+  },
+  "nextSteps": [
+    "Complete template",
+    "Fix failing tests",
+    "Add styles"
+  ],
+  "blockers": [],
+  "filesModified": [
+    {"path": "dashboard.component.ts", "lines": 150},
+    {"path": "dashboard.component.html", "lines": 85}
+  ],
+  "lastUpdated": "2025-11-21T14:30:00Z",
+  "relatedTo": ["dashboard-feature-task", "user-metrics-service"]
+}
+```
+
+**Use implementation-state entries for:**
+- Tracking progress when implementation spans multiple sessions
+- Enabling seamless resumption after interruptions
+- Coordinating between main agent and implementation agents
+- Recording what was tried when debugging errors
+- Maintaining context when switching between tasks
+
+**Update implementation-state when:**
+- Starting new implementation work
+- Significant progress milestone reached
+- Tests status changes
+- Errors encountered or resolved
+- Agent delegation occurs
+- Session ends with incomplete work
+
+## File Management Best Practices
+
+**Initialization**: If `.claude/context/` directory doesn't exist, create it with empty JSON files:
+```bash
+mkdir -p .claude/context
+echo '{"lastUpdated":"","entries":[]}' > .claude/context/tasks.json
+# ... repeat for other files
+```
+
+**Pruning**: Periodically clean up:
+- Completed tasks older than 30 days
+- Obsolete patterns or conventions
+- Resolved issues that are well-documented elsewhere
+
+**Backup**: Context files are git-ignored by default. Consider:
+- Periodically committing snapshots to a separate branch
+- Exporting critical knowledge to permanent documentation
+
+Always optimize for relevance over completeness. Good context accelerates work; bad context creates confusion. **File-based memory allows us to maintain institutional knowledge AND task continuity across sessions without external dependencies.**

-## Core Architecture Framework
-
-### Database Design Philosophy
-- **Domain-Driven Design**: Align database structure with business domains
-- **Data Modeling**: Entity-relationship design, normalization strategies, dimensional modeling
-- **Scalability Planning**: Horizontal vs vertical scaling, sharding strategies
-- **Technology Selection**: SQL vs NoSQL, polyglot persistence, CQRS patterns
-- **Performance by Design**: Query patterns, access patterns, data locality
-
-### Architecture Patterns
-- **Single Database**: Monolithic applications with centralized data
-- **Database per Service**: Microservices with bounded contexts
-- **Shared Database Anti-pattern**: Legacy system integration challenges
-- **Event Sourcing**: Immutable event logs with projections
-- **CQRS**: Command Query Responsibility Segregation

+description: Executes large-scale refactoring and migrations across 5+ files. Use PROACTIVELY when user says 'refactor all', 'migrate X files', 'update pattern across', or task affects 5+ files. Auto-loads architecture-enforcer, circular-dependency-resolver. Safe incremental approach with validation.
+tools: Read, Write, Edit, Bash, Grep, Glob, Skill

+
+You are a specialized refactoring engineer focused on large-scale, safe code transformations in the ISA-Frontend monorepo.
+
+## Automatic Skill Loading
+
+**IMMEDIATELY load these skills at start:**
+
+```
+/skill architecture-enforcer
+/skill circular-dependency-resolver
+```
+
+**Load additional skills as needed:**
+```
+/skill type-safety-engineer      (if fixing any types or adding Zod)
+/skill standalone-component-migrator  (if migrating to standalone)
+/skill test-migration-specialist (if updating tests)
+```
+
+## When to Use This Agent
+
+**✅ Use refactor-engineer when:**
+- Touching 5+ files in coordinated refactoring
+- Pattern migrations (NgModules → Standalone, Jest → Vitest)
+- Architectural changes (layer restructuring)
+- Large-scale renames or API updates
+- Task will take 20+ minutes
+
+**❌ Do NOT use when:**
+- Single file refactoring (use main agent)
+- 2-4 files (use angular-developer)
+- Simple find-replace operations (use main agent with Edit)
+- No architectural impact
+
+**Examples:**
+
+**✅ Good fit:**
+```
+"Migrate all 12 checkout components from NgModules to standalone"
+→ Affects: 12 components + routes + tests = 36+ files
+```
+
+**❌ Poor fit:**
+```
+"Rename getUserData to fetchUserData in user.service.ts"
+→ Use main agent with Edit tool (simple rename)
+```
+
+## Your Mission
+
+Execute large-scale refactoring safely while keeping implementation details in YOUR context. Return summaries based on response_format parameter.
+
+## Workflow
+
+### 1. Intake & Analysis
+
+**Parse the briefing:**
+- Refactoring scope (pattern, files, or glob)
+- Old pattern → New pattern transformation
+- Architectural constraints
+- Validation requirements
+- **response_format**: "concise" (default) or "detailed"
+
+**Analyze impact:**
+```bash
+# Find all affected files
+npx nx graph  # Understand project structure
+
+# Search for pattern usage
+grep -r "old-pattern" libs/
+
+# Check for circular dependencies
+# (architecture-enforcer skill provides checks)
+
+# Identify test files
+find . -name "*.spec.ts" | grep [scope]
+```
+
+**Risk assessment:**
+- Number of files affected
+- Dependency chain depth
+- Public API changes
+- Test coverage gaps
+
+### 2. Safety Planning
+
+**Create incremental plan:**
+1. **Phase 1: Preparation**
+   - Add new pattern alongside old
+   - Ensure tests pass before changes
+
+2. **Phase 2: Migration**
+   - Transform files in dependency order (leaves → roots)
+   - Run tests after each batch
+   - Rollback if failures
+
+3. **Phase 3: Cleanup**
+   - Remove old pattern
+   - Update imports/exports
+   - Final validation
+
+**Define rollback strategy:**
+- Git branch checkpoint
+- Incremental commits per phase
+- Test gates between phases
+
+### 3. Incremental Execution (with Environmental Feedback)
+
+**Provide progress updates for each batch:**
+
+```
+Batch 1/4: Transforming 8 files...
+→ Editing checkout-cart.component.ts
+→ Editing checkout-summary.component.ts
+→ Editing checkout-payment.component.ts
+... (5 more files)
+✓ Batch 1 files transformed
+
+→ Running affected tests... ✓ 24/24 passing
+→ Checking architecture... ✓ No violations
+→ Running lint... ✓ No errors
+→ Type checking... ✓ Build successful
+✓ Batch 1 validated
+
+Batch 2/4: Transforming 7 files...
+```
+
+**For each file batch (5-10 files):**
+
+```bash
+# 1. Transform files (report each file)
+# (Apply Edit operations)
+
+# 2. Run affected tests (report pass/fail immediately)
+npx nx affected:test
+
+# 3. Check architecture (report violations immediately)
+# (architecture-enforcer validates)
+
+# 4. Check for circular deps (report if found)
+# (circular-dependency-resolver checks)
+
+# 5. Lint check (report errors immediately)
+npx nx affected:lint
+
+# 6. Type check (report errors immediately)
+npx nx run-many --target=build --configuration=development
+```
+
+**If any step fails:**
+- STOP immediately
+- Report: "⚠ Batch X failed at step Y: [error]"
+- Analyze failure
+- Fix or rollback batch
+- Do NOT proceed to next batch
+
+### 4. Architectural Validation
+
+**Run comprehensive checks:**
+
+```bash
+# Import boundary validation
+npx nx graph --file=graph.json
+# Parse for violations
+
+# Circular dependency detection
+# (Use circular-dependency-resolver skill)
+
+# Layer violations (Feature→Feature, Domain→Domain)
+# (Use architecture-enforcer skill)
+```
+
+**Validate patterns:**
+- No Feature → Feature imports
+- No OMS → Remission domain violations
+- No relative imports between libs
+- Proper dependency direction (UI → Data Access → API)
+
+### 5. Test Strategy
+
+**Ensure comprehensive coverage:**
+- All affected components have tests
+- Tests updated to match new patterns
+- Integration tests validate interactions
+- E2E tests (if applicable) still pass
+
+**Run test suite:**
+```bash
+# Unit tests
+npx nx affected:test --base=main
+
+# Build validation
+npx nx affected:build --base=main
+
+# Lint validation
+npx nx affected:lint --base=main
+```
+
+### 6. Reporting (Response Format Based)
+
+**If response_format = "concise" (default):**
+
+```
+✓ Refactoring completed: Checkout components → Standalone
+✓ Pattern: NgModule → Standalone components
+
+Impact: 23 files (12 components, 8 services, 3 shared modules)
+Validation: ✓ Tests (145/145), ✓ Build, ✓ Lint, ✓ Architecture
+Breaking changes: None
+```
+
+**If response_format = "detailed":**
+
+```
+✓ Refactoring completed: Checkout Components Migration
+✓ Pattern: NgModule-based → Standalone components
+
+Scope:
+- All checkout feature components (12 total)
+- Associated services and guards (8 files)
+- Route configuration updates (3 files)
+
+Impact analysis:
+- Files modified: 23
+  - Components: 12 (cart, summary, payment, shipping, confirmation, etc.)
+  - Services: 8 (checkout.service, payment.service, etc.)
+  - Tests: 15 (all passing after updates)
+- Lines changed: ~1,850 additions, ~2,100 deletions (net: -250 lines)
+
+Phases completed:
+✓ Phase 1: Preparation (3 files, 12 minutes)
+  - Added standalone: true to all components
+  - Identified required imports from module
+
+✓ Phase 2: Migration (20 files, 4 batches, 35 minutes)
+  - Batch 1: Cart + Summary components (8 files)
+  - Batch 2: Payment + Shipping components (7 files)
+  - Batch 3: Confirmation + Review components (5 files)
+  - Batch 4: Route configuration (3 files)
+
+✓ Phase 3: Cleanup (5 files, 8 minutes)
+  - Removed checkout.module.ts
+  - Removed shared modules (no longer needed)
+  - Updated barrel exports
+
+Validation results:
+✓ Tests: 145/145 passing (100%)
+  - Unit tests: 98 passing
+  - Integration tests: 35 passing
+  - E2E tests: 12 passing
+
+✓ Build: All affected projects built successfully
+  - checkout-feature: ✓
+  - checkout-data-access: ✓
+  - checkout-ui: ✓
+
+✓ Lint: No errors (ran on 23 files)
+✓ Architecture: No boundary violations
+✓ Circular dependencies: None detected
+
+Breaking changes: None
+- All public APIs maintained
+- Imports updated automatically
+
+Deprecations:
+- CheckoutModule (removed)
+- CheckoutSharedModule (removed, functionality moved to standalone imports)
+
+Migration notes:
+- Route configuration now uses direct component imports
+- Lazy loading still works (standalone components support it natively)
+- Tests updated to use TestBed.configureTestingModule with imports array
+- All components use inject() instead of constructor injection (migration bonus)
+
+Performance impact:
+- Bundle size: -12KB gzipped (removed module overhead)
+- Initial load time: ~50ms faster (tree-shaking improvements)
+
+Follow-up recommendations:
+- Consider migrating payment domain next (similar patterns)
+- Update documentation with standalone patterns
+- Remove NgModule references from style guide
+```
+
+**DO NOT include:**
+- Full file diffs (unless debugging is needed)
+- Complete test logs (summary only)
+- Repetitive batch reports
+
+## Refactoring Patterns
+
+### Pattern Migration Example
+
+**Old pattern:**
+```typescript
+// NgModule-based component
+@Component({ ... })
+export class OldComponent { }
+```
+
+**New pattern:**
+```typescript
+// Standalone component
+@Component({
+  standalone: true,
+  imports: [...]
+})
+export class NewComponent { }
+```
+
+### Dependency Order
+
+**Always refactor in this order:**
+1. Leaf nodes (no dependencies)
+2. Intermediate nodes
+3. Root nodes (many dependencies)
+
+**Check order with:**
+```bash
+npx nx graph --focus=[project-name]
+```
+
+### Safe Transformation Steps
+
+**For each file:**
+1. Read current implementation
+2. Apply transformation
+3. Verify syntax (build)
+4. Run tests
+5. Commit checkpoint
+
+### Handling Breaking Changes
+
+**If breaking changes unavoidable:**
+1. Document all breaking changes
+2. Provide migration guide
+3. Update dependent files simultaneously
+4. Verify nothing breaks
+
+## Anti-Patterns to Avoid
+
+❌ Refactoring without tests
+❌ Batch size > 10 files
+❌ Skipping validation steps
+❌ Introducing circular dependencies
+❌ Breaking import boundaries
+❌ Leaving old pattern alongside new (in production)
+❌ Changing behavior during refactoring (refactor OR change, not both)
+
+## Error Handling
+
+**If refactoring fails:**
+
+```
+⚠ Refactoring blocked at Phase [N]: [issue]
+
+Progress:
+✓ Completed: [X files]
+⚠ Failed: [Y files]
+○ Remaining: [Z files]
+
+Failure details:
+- Error: [specific error]
+- File: [problematic file]
+- Attempted: [what was tried]
+
+Rollback status: [safe rollback point]
+Recommendation: [next steps]
+```
+
+**Rollback procedure:**
+1. Discard changes in failed batch
+2. Return to last checkpoint
+3. Analyze failure
+4. Adjust strategy
+5. Retry or report
+
+## Special Cases
+
+### Circular Dependency Resolution
+
+**When detected:**
+1. Use circular-dependency-resolver skill
+2. Analyze dependency graph
+3. Choose fix strategy:
+   - Dependency injection
+   - Interface extraction
+   - Shared code extraction
+   - Lazy imports
+4. Apply fix
+5. Validate resolution
+
+### Architecture Violations
+
+**When detected:**
+1. Use architecture-enforcer skill
+2. Identify violation type
+3. Choose fix strategy:
+   - Move code to correct layer
+   - Create proper abstraction
+   - Extract to shared lib
+4. Apply fix
+5. Re-validate
+
+### Type Safety Improvements
+
+**When adding type safety:**
+1. Use type-safety-engineer skill
+2. Replace `any` types
+3. Add Zod schemas for runtime validation
+4. Create type guards
+5. Update tests
+
+## Performance Considerations
+
+**Large refactoring optimization:**
+- Use Glob for pattern discovery (not manual file lists)
+- Use Grep for code search (not Read every file)
+- Batch operations efficiently
+- Cache build results between batches
+- Use affected commands (not full rebuilds)
+
+## Context Efficiency
+
+**Keep main context clean:**
+- Use Glob/Grep for discovery (don't Read all files upfront)
+- Compress validation output
+- Report summaries, not details
+- Store rollback info in YOUR context only
+
+**Token budget target:** Even large refactoring should stay under 40K tokens through:
+- Surgical reads (only files being modified)
+- Compressed tool outputs
+- Batch summaries (not per-file reports)
+- Internal iteration on failures
+
+## Commit Strategy
+
+**Create checkpoints:**
+```bash
+# After each successful phase
+git add [files]
+git commit -m "refactor(scope): phase N - description"
+```
+
+**DO NOT push** unless briefing explicitly requests it. Refactoring should be reviewable before merge.

-## Testing Best Practices
-
-### Test Organization
-```javascript
-// Example test structure
-describe('UserService', () => {
-  describe('createUser', () => {
-    it('should create user with valid data', async () => {
-      // Arrange
-      const userData = { email: 'test@example.com', name: 'Test User' };
-      
-      // Act
-      const result = await userService.createUser(userData);
-      
-      // Assert
-      expect(result).toHaveProperty('id');
-      expect(result.email).toBe(userData.email);
-    });
-    
-    it('should throw error with invalid email', async () => {
-      // Arrange
-      const userData = { email: 'invalid-email', name: 'Test User' };
-      
-      // Act & Assert
-      await expect(userService.createUser(userData)).rejects.toThrow('Invalid email');
-    });
-  });
-});
-```
-
-Your testing implementations should always include:
-1. **Test Strategy** - Clear testing approach and coverage goals
-2. **Automation Pipeline** - CI/CD integration with quality gates
-3. **Performance Testing** - Load testing and performance benchmarks
-4. **Quality Metrics** - Coverage, reliability, and performance tracking
-5. **Maintenance** - Test maintenance and refactoring strategies
-
-Focus on creating maintainable, reliable tests that provide fast feedback and high confidence in code quality.

+name: test-writer
+description: Generates comprehensive test suites with Vitest + Angular Testing Library. Use PROACTIVELY when user says 'write tests', 'add test coverage', after angular-developer creates features, or when coverage <80%. Handles unit, integration tests and mocking.
+tools: Read, Write, Edit, Bash, Grep, Skill
+model: sonnet
+---
+
+You are a specialized test engineer focused on creating comprehensive, maintainable test suites following ISA-Frontend Vitest standards.
+
+## Automatic Skill Loading
+
+**IMMEDIATELY load at start if applicable:**
+
+```
+/skill test-migration-specialist  (if converting from Jest)
+/skill logging                     (if testing components with logging)
+```
+
+## When to Use This Agent
+
+**✅ Use test-writer when:**
+- Creating test suites for existing code
+- Expanding test coverage (< 80%)
+- Need comprehensive test scenarios (unit + integration)
+- Migrating from Jest to Vitest
+
+**❌ Do NOT use when:**
+- Tests already exist with good coverage (>80%)
+- Only need 1-2 simple test cases (write directly)
+- Testing is part of new feature creation (use angular-developer)
+
+## Your Mission
+
+Generate high-quality test coverage while keeping implementation details in YOUR context. Return summaries based on response_format parameter.
+
+## Workflow
+
+### 1. Intake & Analysis
+
+**Parse the briefing:**
+- Target file(s) to test
+- Coverage type: unit / integration / e2e
+- Specific scenarios to cover
+- Dependencies to mock
+- **response_format**: "concise" (default) or "detailed"
+
+**Analyze target:**
+```bash
+# Read the target file
+cat [target-file]
+
+# Check existing tests
+cat [target-file].spec.ts 2>/dev/null || echo "No existing tests"
+
+# Identify dependencies
+grep -E "import.*from" [target-file]
+```
+
+### 2. Test Planning
+
+**Determine test structure:**
+- **Unit tests**: Focus on pure functions, isolated logic
+- **Integration tests**: Test component + store + service interactions
+- **Rendering tests**: Verify DOM output and user interactions
+
+**Identify what to mock:**
+- External API calls (use vi.mock)
+- Router navigation
+- Third-party services
+- Complex dependencies
+
+**Coverage goals:**
+- All public methods/functions
+- Edge cases and error paths
+- User interaction flows
+- State transitions
+
+### 3. Implementation
+
+**Use Vitest + Angular Testing Library patterns:**
+
+```typescript
+import { describe, it, expect, beforeEach, vi } from 'vitest';
+import { render, screen, fireEvent } from '@testing-library/angular';
+import { ComponentFixture, TestBed } from '@angular/core/testing';
+
+describe('ComponentName', () => {
+  let fixture: ComponentFixture<ComponentName>;
+  let component: ComponentName;
+
+  beforeEach(async () => {
+    await TestBed.configureTestingModule({
+      imports: [ComponentName],
+      providers: [
+        // Mock providers
+      ]
+    }).compileComponents();
+
+    fixture = TestBed.createComponent(ComponentName);
+    component = fixture.componentInstance;
+  });
+
+  it('should render correctly', () => {
+    fixture.detectChanges();
+    expect(component).toBeTruthy();
+  });
+
+  // More tests...
+});
+```
+
+**Mocking patterns:**
+
+```typescript
+// Mock services
+const mockService = {
+  getData: vi.fn().mockResolvedValue({ data: 'test' })
+};
+
+// Mock stores
+const mockStore = signalStore(
+  withState({ data: [] })
+);
+
+// Mock HTTP
+vi.mock('@angular/common/http', () => ({
+  HttpClient: vi.fn()
+}));
+```
+
+**Test user interactions:**
+
+```typescript
+it('should handle button click', async () => {
+  render(ComponentName, {
+    imports: [/* dependencies */]
+  });
+
+  const button = screen.getByRole('button', { name: /submit/i });
+  await fireEvent.click(button);
+
+  expect(screen.getByText(/success/i)).toBeInTheDocument();
+});
+```
+
+### 4. Validation (with Environmental Feedback)
+
+**Provide progress updates:**
+
+```
+Phase 1: Creating test file...
+→ Created file.spec.ts (185 lines, 15 test cases)
+✓ File created
+
+Phase 2: Running tests...
+→ Running tests... ⚠ 12/15 passing
+
+Phase 3: Fixing failures...
+→ Investigating failures: Async timing issues in 3 tests
+→ Adding waitFor() calls...
+→ Rerunning tests... ✓ 15/15 passing
+
+Phase 4: Checking coverage...
+→ Running coverage... ✓ 92% statements, 88% branches
+✓ Coverage target met (>80%)
+```
+
+**Run tests:**
+```bash
+npx nx test [project-name]
+npx nx test [project-name] --coverage
+```
+
+**Iterate until:** All tests pass, coverage >80%
+
+### 5. Reporting (Response Format Based)
+
+**If response_format = "concise" (default):**
+
+```
+✓ Tests created: UserProfileComponent
+✓ File: user-profile.component.spec.ts (15 tests, all passing)
+✓ Coverage: 92% statements, 88% branches
+
+Categories: Rendering (5), Interactions (4), State (4), Errors (2)
+Mocks: UserService, ProfileStore, Router
+```
+
+**If response_format = "detailed":**
+
+```
+✓ Tests created: UserProfileComponent
+
+Test file: user-profile.component.spec.ts (185 lines, 15 test cases)
+
+Test categories:
+- Rendering tests (5): Initial state, loading state, error state, success state, empty state
+- User interaction tests (4): Form input, submit button, cancel button, avatar upload
+- State management tests (4): Store updates, computed values, async loading, error handling
+- Error handling tests (2): Network failures, validation errors
+
+Mocking strategy:
+- UserService: vi.mock with mockResolvedValue for async calls
+- ProfileStore: signalStore with initial state, mocked methods
+- Router: vi.mock for navigation verification
+- HttpClient: Not mocked (using ProfileStore mock instead)
+
+Coverage achieved:
+- Statements: 92% (target: 80%)
+- Branches: 88% (target: 80%)
+- Functions: 100%
+- Lines: 91%
+
+Key scenarios covered:
+- Happy path: User loads profile, edits fields, submits successfully
+- Error path: Network failure shows error message, retry button works
+- Edge cases: Empty profile data, concurrent requests, validation errors
+
+Test patterns used:
+- TestBed.configureTestingModule for component setup
+- Testing Library queries (screen.getByRole, screen.getByText)
+- fireEvent for user interactions
+- waitFor for async operations
+- vi.fn() for spy/mock functions
+```
+
+**DO NOT include:**
+- Full test file contents
+- Complete test output logs (show summary only)
+
+## Test Organization
+
+**Structure tests logically:**
+
+```typescript
+describe('ComponentName', () => {
+  describe('Rendering', () => {
+    // Rendering tests
+  });
+
+  describe('User Interactions', () => {
+    // Click, input, navigation tests
+  });
+
+  describe('State Management', () => {
+    // Store integration, state updates
+  });
+
+  describe('Error Handling', () => {
+    // Error scenarios, edge cases
+  });
+});
+```
+
+## Common Patterns
+
+### Testing Components with Stores
+
+```typescript
+import { provideSignalStore } from '@ngrx/signals';
+import { MyStore } from './my.store';
+
+beforeEach(() => {
+  TestBed.configureTestingModule({
+    imports: [MyComponent],
+    providers: [provideSignalStore(MyStore)]
+  });
+});
+```
+
+### Testing Async Operations
+
+```typescript
+it('should load data', async () => {
+  const { fixture } = await render(MyComponent);
+
+  // Wait for async operations
+  await fixture.whenStable();
+
+  expect(screen.getByText(/loaded/i)).toBeInTheDocument();
+});
+```
+
+### Testing Signals
+
+```typescript
+it('should update signal value', () => {
+  const store = TestBed.inject(MyStore);
+
+  store.updateValue('new value');
+
+  expect(store.value()).toBe('new value');
+});
+```
+
+## Anti-Patterns to Avoid
+
+❌ Testing implementation details (private methods)
+❌ Brittle selectors (use semantic queries from Testing Library)
+❌ Not cleaning up after tests (memory leaks)
+❌ Over-mocking (test real behavior when possible)
+❌ Snapshot tests without clear purpose
+❌ Skipping error cases
+
+## Error Handling
+
+**If tests fail:**
+1. Analyze failure output
+2. Fix test or identify product bug
+3. Iterate up to 3 times

+
+## Integration with Test Migration
+
+**If migrating from Jest:**
+- Load test-migration-specialist skill
+- Convert Spectator → Angular Testing Library
+- Replace Jest matchers with Vitest
+- Update mock patterns (jest.fn → vi.fn)
+
+## Context Efficiency
+
+**Keep main context clean:**
+- Read only necessary files
+- Compress test output (show summary, not full logs)
+- Iterate on failures internally
+- Return only summary + key insights
+
+**Token budget target:** Keep execution under 20K tokens by being surgical with reads and aggressive with compression.

 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
 
+## Determining the Scope
+
+The scope in commit messages MUST be the `name` field from the affected library's `project.json`:
+
+1. **Check the file path**: `libs/ui/label/src/...` → Look at `libs/ui/label/project.json`

 - `--no-verify`: Skip running the pre-commit checks (lint, build, generate:docs)

+
+## Amend Rules (CRITICAL)
+
+**ONLY use `--amend` in these specific cases:**
+
+1. **Adding pre-commit hook fixes**: If a pre-commit hook modified files (formatting, linting auto-fixes), you may amend to include those changes.
+
+2. **Before amending, ALWAYS verify:**
+   ```bash
+   # Check authorship - NEVER amend another developer's commit
+   git log -1 --format='%an %ae'
+
+   # Check not pushed - NEVER amend pushed commits
+   git status  # Should show "Your branch is ahead of..."
+   ```
+
+3. **If either check fails:**
+   - Create a NEW commit instead
+   - Never amend commits authored by others
+   - Never amend commits already pushed to remote
+
+**Example workflow for pre-commit hook changes:**
+```bash
+# 1. Initial commit triggers pre-commit hook
+git commit -m "feat(scope): add feature"
+# Hook modifies files...
+
+# 2. Verify safe to amend
+git log -1 --format='%an %ae'  # Your name/email
+git status                      # "Your branch is ahead..."
+
+# 3. Stage hook changes and amend
+git add .
+git commit --amend --no-edit
+```

-# /dev:add-e2e-attrs - Add E2E Test Attributes
-
-Add required E2E test attributes (`data-what`, `data-which`, dynamic `data-*`) to component templates for QA automation.
-
-## Parameters
-- `component-path`: Path to component directory or HTML template file
-
-## Required E2E Attributes
-
-### Core Attributes (Required)
-1. **`data-what`**: Semantic description of element's purpose
-   - Example: `data-what="submit-button"`, `data-what="search-input"`
-2. **`data-which`**: Unique identifier for the specific instance
-   - Example: `data-which="primary"`, `data-which="customer-{{ customerId }}"`
-
-### Dynamic Attributes (Contextual)
-3. **`data-*`**: Additional context based on state/data
-   - Example: `data-status="active"`, `data-index="0"`
-
-## Tasks
-
-### 1. Analyze Component Template
-- Read component HTML template
-- Identify interactive elements that need E2E attributes:
-  - Buttons (`button`, `ui-button`)
-  - Inputs (`input`, `textarea`, `select`)
-  - Links (`a`, `routerLink`)
-  - Custom interactive components
-  - Form elements
-  - Clickable elements (`(click)` handlers)
-
-### 2. Add Missing Attributes
-
-**Buttons:**
-```html
-<!-- BEFORE -->
-<button (click)="submit()">Submit</button>
-
-<!-- AFTER -->
-<button
-  (click)="submit()"
-  data-what="submit-button"
-  data-which="form-primary">
-  Submit
-</button>
-```
-
-**Inputs:**
-```html
-<!-- BEFORE -->
-<input [(ngModel)]="searchTerm" placeholder="Search..." />
-
-<!-- AFTER -->
-<input
-  [(ngModel)]="searchTerm"
-  placeholder="Search..."
-  data-what="search-input"
-  data-which="main-search" />
-```
-
-**Dynamic Lists:**
-```html
-<!-- BEFORE -->
-@for (item of items; track item.id) {
-  <li (click)="selectItem(item)">{{ item.name }}</li>
-}
-
-<!-- AFTER -->
-@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">
-    {{ item.name }}
-  </li>
-}
-```
-
-**Links:**
-```html
-<!-- BEFORE -->
-<a routerLink="/orders/{{ orderId }}">View Order</a>
-
-<!-- AFTER -->
-<a
-  [routerLink]="['/orders', orderId]"
-  data-what="order-link"
-  [attr.data-which]="orderId">
-  View Order
-</a>
-```
-
-**Custom Components:**
-```html
-<!-- BEFORE -->
-<ui-button (click)="save()">Save</ui-button>
-
-<!-- AFTER -->
-<ui-button
-  (click)="save()"
-  data-what="save-button"
-  data-which="order-form">
-  Save
-</ui-button>
-```
-
-### 3. Naming Conventions
-
-**`data-what` Guidelines:**
-- Use kebab-case
-- Be descriptive but concise
-- Common 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)
-  - `*-dropdown` (status-dropdown, category-dropdown)
-
-**`data-which` Guidelines:**
-- Unique identifier for the instance
-- Use dynamic binding for list items: `[attr.data-which]="item.id"`
-- Static for unique elements: `data-which="primary"`
-- Combine with context: `data-which="customer-{{ customerId }}-edit"`
-
-### 4. Scan for Coverage
-Check template coverage:
-```bash
-# Count interactive elements
-grep -E '(click)=|routerLink|button|input|select|textarea' [template-file]
-
-# Count elements with data-what
-grep -c 'data-what=' [template-file]
-
-# List elements missing E2E attributes
-grep -E '(click)=|button' [template-file] | grep -v 'data-what='
-```
-
-### 5. Validate Attributes
-- No duplicates in `data-which` within same view
-- All interactive elements have both `data-what` and `data-which`
-- Dynamic attributes use proper Angular binding: `[attr.data-*]`
-- Attributes don't contain sensitive data (passwords, tokens)
-
-### 6. Update Component Tests
-Add E2E attribute selectors to tests:
-```typescript
-// Use E2E attributes for element selection
-const submitButton = fixture.nativeElement.querySelector('[data-what="submit-button"][data-which="primary"]');
-expect(submitButton).toBeTruthy();
-```
-
-### 7. Document Attributes
-Add comment block at top of template:
-```html
-<!--
-E2E Test Attributes:
-- data-what="submit-button" data-which="primary" - Main form submission
-- data-what="cancel-button" data-which="primary" - Cancel action
-- data-what="search-input" data-which="main" - Product search field
--->
-```
-
-## Output
-Provide summary:
-- Template analyzed: [path]
-- Interactive elements found: [count]
-- Attributes added: [count]
-- Coverage: [percentage]% (elements with E2E attrs / total interactive elements)
-- List of added attributes with descriptions
-- Validation status: ✅/❌
-
-## Common Patterns by Component Type
-
-**Form Components:**
-- `data-what="[field]-input" data-which="[form-name]"`
-- `data-what="submit-button" data-which="[form-name]"`
-- `data-what="cancel-button" data-which="[form-name]"`
-
-**List/Table Components:**
-- `data-what="list-item" [attr.data-which]="item.id"`
-- `data-what="edit-button" [attr.data-which]="item.id"`
-- `data-what="delete-button" [attr.data-which]="item.id"`
-
-**Navigation Components:**
-- `data-what="nav-link" data-which="[destination]"`
-- `data-what="breadcrumb" data-which="[level]"`
-
-**Dialog Components:**
-- `data-what="confirm-button" data-which="dialog"`
-- `data-what="close-button" data-which="dialog"`

+
+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
+
+---
+
+## 📊 Summary
+
+- **Commits**: X commits across Y branches
+- **PRs I Merged**: Z pull requests (as committer)
+- **My PRs Merged by Colleagues**: W pull requests
+- **Primary Branch**: branch-name
+- **Work Duration**: Started at HH:MM, worked for Xh Ym

+
+# Generate Changelog
+
+Generate changelog entries from git commits between version tags: $ARGUMENTS
+
+## Current State
+
+- Latest Tag: !`git tag --sort=-creatordate | head -n 1`
+- CHANGELOG.md: !`test -f CHANGELOG.md && echo "exists" || echo "does not exist"`
+- Commits Since Last Tag: !`git log $(git tag --sort=-creatordate | head -n 1)..HEAD --oneline | wc -l`
+- Current Branch: !`git branch --show-current`
+
+## Tasks
+
+### 1. Determine Version Range
+
+**Objective**: Identify the commit range for changelog generation
+
+- [ ] Check if version argument provided
+  - If `[version]` provided: Use as the new version number
+  - If `--since [tag]` provided: Use custom tag as starting point
+  - Otherwise: Use latest tag as starting point
+
+```bash
+# Find latest tag
+LATEST_TAG=$(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

-# /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

+---
+
+# /quality - Code Quality Analysis
+
+Comprehensive quality analysis including bundle sizes and test coverage.
+
+## Subcommands
+
+- `bundle` - Analyze production bundle sizes
+- `coverage [library-name]` - Test coverage analysis
+- No argument - Run both analyses
+- `[library-name]` - Coverage for specific library
+
+## Bundle Analysis
+
+### 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 (Optional)
+```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. Bundle 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
+
+**Dependency Optimization:**
+- Replace large libraries with smaller alternatives
+- Remove unused dependencies
+- Use tree-shakeable imports
+
+---
+
+## Coverage Analysis
+
+### 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 in: `coverage/libs/[domain]/[layer]/[name]/`
+
+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
+
+### 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 and guards
+
+**Low Priority:**
+- Getters/setters
+- Simple property assignments
+
+### 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)
+

+name: angular-effects-alternatives
+description: This skill should be used when writing Angular code with signals and effects. Use when deciding whether to use effect(), computed(), or reactive patterns for state management. Applies to all Angular components and services using signals, especially when considering effect() for state propagation, data synchronization, or reactive flows. Essential for code review of effect usage and refactoring imperative patterns to declarative alternatives.
+---
+
+# Angular Effects Alternatives
+
+## Overview
+
+This skill guides proper usage of Angular's `effect()` and provides declarative alternatives for common patterns. Effects are frequently misused for state propagation, leading to circular updates, maintenance issues, and violations of reactive principles. This skill prevents anti-patterns and promotes maintainable, declarative code.
+
+## When to Use Effects (Valid Use Cases)
+
+Effects are **primarily for rendering content that cannot be rendered through data binding**. Valid use cases are limited to:
+
+### 1. Logging
+Recording application events or debugging:
+
+```typescript
+effect(() => {
+  const error = this.error();
+  if (error) {
+    console.error('Error occurred:', error);
+  }
+});
+```
+
+### 2. Canvas Painting
+Custom graphics rendering (e.g., Angular Three library, Chart.js integration):
+
+```typescript
+effect(() => {
+  const data = this.chartData();
+  this.renderCanvas(data);
+});
+```
+
+### 3. Custom DOM Behavior
+Imperative APIs that require direct DOM manipulation:
+
+```typescript
+effect(() => {
+  const message = this.notificationMessage();
+  if (message) {
+    this.snackBar.open(message, 'Close');
+  }
+});
+```
+
+**Key principle:** Data binding is the preferred way to display data. Effects should only be used when data binding is insufficient.
+
+## Understanding Auto-Tracking
+
+Angular automatically tracks signals accessed during effect execution, **even within called methods**:
+
+```typescript
+effect(() => {
+  this.logError(); // Signal tracking happens inside this method
+});
+
+logError(): void {
+  const error = this.error(); // This signal is automatically tracked
+  if (error) {
+    console.error(error);
+  }
+}
+```
+
+**Implication:** Auto-tracking makes effect dependencies non-obvious and hard to maintain. This is a primary reason to avoid effects for state management.
+
+## When NOT to Use Effects (Anti-Patterns)
+
+### ❌ Anti-Pattern 1: State Propagation
+
+**NEVER use effects to propagate state changes to other state:**
+
+```typescript
+// ❌ WRONG - Anti-pattern
+effect(() => {
+  const value = this.source();
+  this.derived.set(value * 2);
+});
+```
+
+**Problems:**
+- Risk of circular updates and infinite loops
+- Hard to maintain due to implicit tracking
+- Violates declarative reactive principles
+- Inappropriate glitch-free semantics
+
+### ❌ Anti-Pattern 2: Synchronizing Signals
+
+```typescript
+// ❌ WRONG - Anti-pattern
+effect(() => {
+  const filter = this.filter();
+  this.loadData(filter);
+});
+```
+
+### ❌ Anti-Pattern 3: Event Emulation
+
+```typescript
+// ❌ WRONG - Anti-pattern
+effect(() => {
+  const count = this.itemCount();
+  this.countChanged.emit(count);
+});
+```
+
+**Why signals ≠ events:** Signals are designed to be glitch-free, collapsing multiple updates. This makes them inappropriate for representing discrete events.
+
+## Decision Tree: Effect vs Alternative
+
+```
+Need to react to signal changes?
+│
+├─ Synchronous derivation?
+│  └─ ✅ Use computed()
+│
+├─ Asynchronous derivation?
+│  └─ ✅ Use Resource API
+│
+├─ Complex reactive flow with race conditions?
+│  └─ ✅ Use RxJS (toObservable + operators + toSignal)
+│
+├─ Event-based trigger (not state change)?
+│  └─ ✅ React to event directly, not signal
+│
+├─ Need RxJS operators with signals?
+│  └─ ✅ Use reactive helpers (rxMethod, deriveAsync)
+│
+└─ Rendering non-data-bound content (logging, canvas, imperative API)?
+   └─ ✅ Use effect()
+```
+
+## Recommended Alternatives
+
+### Alternative 1: Use `computed()` for Synchronous Derivations
+
+**When to use:** Deriving new state synchronously from existing signals.
+
+```typescript
+// ✅ CORRECT - Declarative
+const derived = computed(() => {
+  return this.baseSignal() * 2;
+});
+
+const fullName = computed(() => {
+  return `${this.firstName()} ${this.lastName()}`;
+});
+```
+
+**Benefits:**
+- Declarative and maintainable
+- Automatic dependency tracking
+- Memoized and efficient
+- No risk of circular updates
+
+### Alternative 2: Use Resource API for Asynchronous Derivations
+
+**When to use:** Loading data based on reactive parameters.
+
+```typescript
+// ✅ CORRECT - Declarative async state
+readonly itemsResource = resource({
+  params: this.filter,
+  loader: ({ params, abortSignal }) => {
+    return this.dataService.load(params, abortSignal);
+  }
+});
+
+readonly items = computed(() => this.itemsResource.value() ?? []);
+```
+
+**Benefits:**
+- Automatic race condition handling
+- Built-in loading/error states
+- Declarative parameter tracking
+- Cancellation support
+
+**See also:** `ngrx-resource-api` skill for detailed Resource API patterns.
+
+### Alternative 3: React to Events, Not State Changes
+
+**When to use:** User interactions or DOM events should trigger actions.
+
+```typescript
+// ❌ WRONG - Reacting to signal change
+effect(() => {
+  const searchTerm = this.searchTerm();
+  this.search(searchTerm);
+});
+
+// ✅ CORRECT - React to event
+<input (input)="search($event.target.value)" />
+
+// Component
+search(term: string): void {
+  this.searchTerm.set(term);
+  this.performSearch(term);
+}
+```
+
+**Benefits:**
+- Clear causality (event → action)
+- No auto-tracking complexity
+- Explicit control flow
+
+### Alternative 4: RxJS Integration
+
+**When to use:** Complex reactive flows requiring operators like `debounceTime`, `switchMap`, `combineLatest`.
+
+```typescript
+// ✅ CORRECT - RxJS for complex flows
+readonly searchTerm = signal('');
+readonly searchTerm$ = toObservable(this.searchTerm);
+
+readonly results$ = this.searchTerm$.pipe(
+  debounceTime(300),
+  distinctUntilChanged(),
+  switchMap(term => this.searchService.search(term))
+);
+
+readonly results = toSignal(this.results$, { initialValue: [] });
+```
+
+**Benefits:**
+- Full RxJS operator ecosystem
+- Race condition prevention (`switchMap`)
+- Powerful composition
+- Type-safe streams
+
+**Pattern:** Signal → Observable (toObservable) → RxJS operators → Signal (toSignal)
+
+### Alternative 5: Reactive Helpers
+
+**When to use:** Need RxJS operators but prefer signal-centric API.
+
+#### Using `rxMethod` (NgRx Signal Store)
+
+```typescript
+readonly loadItem = rxMethod<number>(
+  pipe(
+    tap(() => patchState(this, { loading: true })),
+    switchMap(id => this.service.findById(id)),
+    tap(item => patchState(this, { item, loading: false }))
+  )
+);
+
+// Call with signal or value
+constructor() {
+  this.loadItem(this.selectedId);
+}
+```
+
+#### Using `deriveAsync` (ngxtension)
+
+```typescript
+readonly data = deriveAsync(() => {
+  const filter = this.filter();
+  return this.service.load(filter);
+});
+```
+
+**Benefits:**
+- Signal-friendly API
+- RxJS operator support
+- Cleaner than manual Observable conversion
+- Automatic subscription management
+
+## The `explicitEffect` Consideration
+
+Some libraries provide `explicitEffect` to restrict auto-tracking:
+
+```typescript
+// Uses untracked() internally to limit tracking
+explicitEffect(this.id, (id) => {
+  this.store.load(id);
+});
+```
+
+**Evaluation:**
+- ✅ Mitigates auto-tracking drawbacks
+- ✅ Makes dependencies explicit
+- ❌ Still imperative (not declarative)
+- ❌ Doesn't solve circular update risks
+- ❌ Less idiomatic than reactive alternatives
+
+**Recommendation:** Prefer declarative patterns (computed, Resource API, RxJS) over `explicitEffect`.
+
+## Common Refactoring Patterns
+
+### Pattern 1: Effect for State Sync → computed()
+
+```typescript
+// ❌ Before
+effect(() => {
+  const x = this.x();
+  const y = this.y();
+  this.sum.set(x + y);
+});
+
+// ✅ After
+readonly sum = computed(() => this.x() + this.y());
+```
+
+### Pattern 2: Effect for Async Load → Resource API
+
+```typescript
+// ❌ Before
+effect(() => {
+  const id = this.selectedId();
+  this.loadItem(id);
+});
+
+// ✅ After
+readonly itemResource = resource({
+  params: this.selectedId,
+  loader: ({ params }) => this.service.loadItem(params)
+});
+```
+
+### Pattern 3: Effect for Debounced Search → RxJS
+
+```typescript
+// ❌ Before
+effect(() => {
+  const term = this.searchTerm();
+  // No way to debounce within effect
+  this.search(term);
+});
+
+// ✅ After
+readonly searchTerm$ = toObservable(this.searchTerm);
+readonly results = toSignal(
+  this.searchTerm$.pipe(
+    debounceTime(300),
+    switchMap(term => this.searchService.search(term))
+  ),
+  { initialValue: [] }
+);
+```
+
+### Pattern 4: Effect for Event Notification → Direct Event Handling
+
+```typescript
+// ❌ Before
+effect(() => {
+  const value = this.value();
+  this.valueChange.emit(value);
+});
+
+// ✅ After
+updateValue(newValue: string): void {
+  this.value.set(newValue);
+  this.valueChange.emit(newValue);
+}
+```
+
+## Code Review Checklist
+
+When reviewing code with `effect()`, ask:
+
+- [ ] Is this for rendering non-data-bound content? (logging, canvas, imperative APIs)
+  - **YES:** Effect is appropriate
+  - **NO:** Continue checklist
+
+- [ ] Is this synchronous state derivation?
+  - **YES:** Use `computed()` instead
+
+- [ ] Is this asynchronous data loading?
+  - **YES:** Use Resource API instead
+
+- [ ] Does this need RxJS operators (debounce, switchMap, etc.)?
+  - **YES:** Use RxJS integration or reactive helpers instead
+
+- [ ] Is this reacting to a user event?
+  - **YES:** Handle event directly instead
+
+- [ ] Could this cause circular updates?
+  - **YES:** Refactor immediately - this will cause bugs
+
+## Anti-Pattern Detection Rules
+
+Flag any effect that:
+
+1. **Calls `set()` or `update()` on signals** - Likely state propagation anti-pattern
+2. **Calls service methods that update state** - Hidden state propagation
+3. **Emits events based on signal changes** - Signal/event semantic mismatch
+4. **Has try/catch for async operations** - Should use Resource API
+5. **Would benefit from debouncing/throttling** - Should use RxJS
+
+## Migration Strategy
+
+When converting effects to alternatives:
+
+1. **Identify effect purpose** - State derivation? Async load? Event handling?
+2. **Choose appropriate alternative** - Use decision tree above
+3. **Implement replacement** - Follow patterns in this skill
+4. **Test thoroughly** - Ensure reactive flow works correctly
+5. **Remove effect** - Clean up unused code
+
+## Key Principles
+
+1. **Effects are for side effects, not state management**
+2. **Prefer declarative over imperative**
+3. **Use computed() for sync, Resource API for async**
+4. **React to events, not state changes**
+5. **RxJS for complex reactive flows**
+6. **Auto-tracking is powerful but opaque - avoid when possible**
+
+## When in Doubt
+
+Ask: "Can the user see this without an effect using data binding?"
+- **YES:** Don't use effect, use data binding
+- **NO:** Effect might be appropriate (but verify against decision tree)

+- Writing Architecture Decision Records (ADRs)
+- Documenting system design and component relationships
+- Creating PlantUML or Mermaid diagrams
+
+## Available Frameworks
+
+### C4 Model
+Best for: Visualizing software architecture at different abstraction levels
+
+Levels:
+1. **Context** - System landscape and external actors
+2. **Container** - High-level technology choices (apps, databases, etc.)
+3. **Component** - Internal structure of containers
+4. **Code** - Class/module level detail (optional)
+
+See: `@references/c4-model.md` for patterns and examples
+
+### Arc42 Template
+Best for: Comprehensive architecture documentation
+
+Sections:
+1. Introduction and Goals
+2. Constraints
+3. Context and Scope
+4. Solution Strategy
+5. Building Block View
+6. Runtime View
+7. Deployment View
+8. Cross-cutting Concepts
+9. Architecture Decisions
+10. Quality Requirements
+11. Risks and Technical Debt
+12. Glossary
+
+See: `@references/arc42.md` for template structure
+
+### Architecture Decision Records (ADRs)
+Best for: Documenting individual architectural decisions
+
+See: `@references/adr-template.md` for format and examples
+
+## Workflow
+
+### 1. Discovery Phase
+```bash
+# Find existing architecture files
+find . -name "*architecture*" -o -name "*.puml" -o -name "*.mmd"
+
+# Identify service boundaries
+cat nx.json docker-compose.yml
+
+# Check for existing ADRs
+ls -la docs/adr/ docs/decisions/
+```
+
+### 2. Analysis Phase
+- Analyze codebase structure (`libs/`, `apps/`)
+- Identify dependencies from `tsconfig.base.json` paths
+- Review service boundaries from `project.json` tags
+- Map data flow from API definitions
+
+### 3. Documentation Phase
+Based on the request, create appropriate documentation:
+
+**For C4 diagrams:**
+```
+docs/architecture/
+├── c4-context.puml
+├── c4-container.puml
+└── c4-component-[name].puml
+```
+
+**For ADRs:**
+```
+docs/adr/
+├── 0001-record-architecture-decisions.md
+├── 0002-[decision-title].md
+└── template.md
+```
+
+**For Arc42:**

+  - `libs/[domain]/ui/` - Presentational components
+  - `libs/[domain]/util/` - Utilities
+
+### Key Architectural Patterns
+- **Nx Monorepo** with strict module boundaries
+- **NgRx Signal Store** for state management
+- **Standalone Components** (Angular 20+)
+- **Domain-Driven Design** library organization
+
+### Documentation Locations

+# ADR-0002: Adopt NgRx Signal Store for State Management
+
+## Status
+Accepted
+
+## Date
+2024-03-01
+
+## Context
+We need a state management solution that:
+- Integrates well with Angular signals
+- Provides predictable state updates
+- Supports devtools for debugging
+- Has good TypeScript support
+
+## Decision
+We will use NgRx Signal Store for new features and gradually migrate existing stores.
+
+## Consequences
+
+### Positive
+- Native signal integration
+- Simpler boilerplate than classic NgRx
+- Better performance with fine-grained reactivity
+- Excellent TypeScript inference
+
+### Negative
+- Migration effort for existing NgRx stores
+- Different patterns from classic NgRx
+
+### Neutral
+- Team needs to learn new API
+
+## Alternatives Considered
+
+### Classic NgRx (Store + Effects)
+- Pros: Mature, well-documented
+- Cons: Verbose boilerplate, doesn't leverage signals
+- Why rejected: Signal Store is the future direction
+
+### Akita
+- Pros: Less boilerplate
+- Cons: Not Angular-native, less community support
+- Why rejected: NgRx has better Angular integration

+description: This skill should be used when writing or reviewing CSS animations in Angular components. Use when creating entrance/exit animations, implementing @keyframes instead of @angular/animations, applying timing functions and fill modes, creating staggered animations, or ensuring GPU-accelerated performance. Essential for modern Angular 20+ components using animate.enter/animate.leave directives and converting legacy Angular animations to native CSS.
+---
+
+# CSS @keyframes Animations
+
+## Overview
+
+Implement native CSS @keyframes animations for Angular applications, replacing @angular/animations with GPU-accelerated, zero-bundle-size alternatives. This skill provides comprehensive guidance on creating performant entrance/exit animations, staggered effects, and proper timing configurations.
+
+## When to Use This Skill
+
+Apply this skill when:
+- **Writing Angular components** with entrance/exit animations
+- **Converting @angular/animations** to native CSS @keyframes
+- **Implementing animate.enter/animate.leave** in Angular 20+ templates
+- **Creating staggered animations** for lists or collections
+- **Debugging animation issues** (snap-back, wrong starting positions, choppy playback)
+- **Optimizing animation performance** for GPU acceleration
+- **Reviewing animation code** for accessibility and best practices
+
+## Quick Start
+
+### Basic Animation Setup
+
+1. **Define @keyframes** in component CSS:
+```css
+@keyframes fadeIn {
+  from { opacity: 0; }
+  to { opacity: 1; }
+}
+```
+
+2. **Apply animation** to element:
+```css
+.element {
+  animation: fadeIn 0.3s ease-out;
+}
+```
+
+3. **Use with Angular 20+ directives**:
+```html
+@if (visible()) {
+  <div animate.enter="fade-in" animate.leave="fade-out">
+    Content
+  </div>
+}
+```
+
+### Common Pitfall: Element Snaps Back
+
+**Problem:** Element returns to original state after animation completes.
+
+**Solution:** Add `forwards` fill mode:
+```css
+.element {
+  animation: fadeOut 1s forwards;
+}
+```
+
+### Common Pitfall: Animation Conflicts with State Transitions
+
+**Problem:** Entrance animation overrides initial state transforms (e.g., stacked cards appear unstacked then jump).
+
+**Solution:** Animate only properties that don't conflict with state. Use opacity-only animations when transforms are state-driven:
+```css
+/* BAD: Overrides stacked transform */
+@keyframes cardEntrance {
+  from { transform: translateY(20px); opacity: 0; }
+  to { transform: translateY(0); opacity: 1; }
+}
+
+/* GOOD: Only animates opacity, allows state transforms to apply */
+@keyframes cardEntrance {
+  from { opacity: 0; }
+  to { opacity: 1; }
+}
+```
+
+## Core Principles
+
+### 1. GPU-Accelerated Properties Only
+
+**Always use** for animations:
+- `transform` (translate, rotate, scale)
+- `opacity`
+
+**Avoid animating** (triggers layout recalculation):
+- `width`, `height`
+- `top`, `left`, `right`, `bottom`
+- `margin`, `padding`
+- `font-size`
+
+### 2. Fill Modes
+
+| Fill Mode | Behavior | Use Case |
+|-----------|----------|----------|
+| `forwards` | Keep end state | Exit animations (stay invisible) |
+| `backwards` | Apply start state during delay | Entrance with delay (prevent flash) |
+| `both` | Both of above | Complex sequences |
+
+### 3. Timing Functions
+
+Choose appropriate easing for animation type:
+
+```css
+/* Entrance animations - ease-out (fast start, slow end) */
+animation-timing-function: cubic-bezier(0, 0, 0.58, 1);
+
+/* Exit animations - ease-in (slow start, fast end) */
+animation-timing-function: cubic-bezier(0.42, 0, 1, 1);
+
+/* Bouncy overshoot effect */
+animation-timing-function: cubic-bezier(0.34, 1.56, 0.64, 1);
+```
+
+Tool: [cubic-bezier.com](https://cubic-bezier.com) for custom curves.
+
+### 4. Staggered Animations
+
+Create cascading effects using CSS custom properties:
+
+**Template:**
+```html
+@for (item of items(); track item.id; let idx = $index) {
+  <div [style.--i]="idx" class="stagger-item">
+    {{ item.name }}
+  </div>
+}
+```
+
+**CSS:**
+```css
+.stagger-item {
+  animation: fadeSlideIn 0.5s ease-out backwards;
+  animation-delay: calc(var(--i, 0) * 100ms);
+}
+```
+
+### 5. Accessibility
+
+Always respect reduced motion preferences:
+
+```css
+@media (prefers-reduced-motion: reduce) {
+  .animated {
+    animation: none;
+    /* Or use simpler, faster animation */
+    animation-duration: 0.1s;
+  }
+}
+```
+
+## Common Animation Patterns
+
+### Fade Entrance/Exit
+
+```css
+@keyframes fadeIn {
+  from { opacity: 0; }
+  to { opacity: 1; }
+}
+
+@keyframes fadeOut {
+  from { opacity: 1; }
+  to { opacity: 0; }
+}
+
+.fade-in { animation: fadeIn 0.3s ease-out; }
+.fade-out { animation: fadeOut 0.3s ease-in forwards; }
+```
+
+### Slide Entrance
+
+```css
+@keyframes slideInUp {
+  from {
+    opacity: 0;
+    transform: translateY(20px);
+  }
+  to {
+    opacity: 1;
+    transform: translateY(0);
+  }
+}
+
+.slide-in-up { animation: slideInUp 0.3s ease-out; }
+```
+
+### Scale Entrance
+
+```css
+@keyframes scaleIn {
+  from {
+    opacity: 0;
+    transform: scale(0.9);
+  }
+  to {
+    opacity: 1;
+    transform: scale(1);
+  }
+}
+
+.scale-in { animation: scaleIn 0.2s ease-out; }
+```
+
+### Loading Spinner
+
+```css
+@keyframes spin {
+  to { transform: rotate(360deg); }
+}
+
+.spinner {
+  width: 40px;
+  height: 40px;
+  border: 3px solid #f3f3f3;
+  border-top: 3px solid #3498db;
+  border-radius: 50%;
+  animation: spin 1s linear infinite;
+}
+```
+
+### Shake (Error Feedback)
+
+```css
+@keyframes shake {
+  0%, 100% { transform: translateX(0); }
+  10%, 30%, 50%, 70%, 90% { transform: translateX(-5px); }
+  20%, 40%, 60%, 80% { transform: translateX(5px); }
+}
+
+.error-input {
+  animation: shake 0.5s ease-in-out;
+}
+```
+
+## Angular 20+ Integration
+
+### Basic Usage with animate.enter/animate.leave
+
+```typescript
+@Component({
+  template: `
+    @if (show()) {
+      <div animate.enter="fade-in" animate.leave="fade-out">
+        Content
+      </div>
+    }
+  `,
+  styles: [`
+    .fade-in { animation: fadeIn 0.3s ease-out; }
+    .fade-out { animation: fadeOut 0.3s ease-in forwards; }
+
+    @keyframes fadeIn {
+      from { opacity: 0; }
+      to { opacity: 1; }
+    }
+
+    @keyframes fadeOut {
+      from { opacity: 1; }
+      to { opacity: 0; }
+    }
+  `]
+})
+```
+
+### Dynamic Animation Classes
+
+```typescript
+@Component({
+  template: `
+    @if (show()) {
+      <div [animate.enter]="enterAnim()" [animate.leave]="leaveAnim()">
+        Content
+      </div>
+    }
+  `
+})
+export class DynamicAnimComponent {
+  show = signal(false);
+  enterAnim = signal('slide-in-up');
+  leaveAnim = signal('slide-out-down');
+}
+```
+
+## Debugging Animations
+
+### Common Issues
+
+| Problem | Cause | Solution |
+|---------|-------|----------|
+| Animation doesn't run | Missing duration | Add `animation-duration: 0.3s` |
+| Element snaps back | No fill mode | Add `animation-fill-mode: forwards` |
+| Wrong starting position during delay | No backwards fill | Add `animation-fill-mode: backwards` |
+| Choppy animation | Animating layout properties | Use `transform` instead |
+| State conflict (jump/snap) | Animation overrides state transforms | Animate only opacity, not transform |
+

+- **Chrome DevTools** → More Tools → Animations panel
+- **Firefox DevTools** → Inspector → Animations tab
+
+### Animation Events
+
+```typescript
+element.addEventListener('animationend', (e) => {
+  console.log('Animation completed:', e.animationName);
+  // Clean up, remove element, etc.
+});
+```

+
+### assets/animations.css
+
+Ready-to-use CSS file with common animation patterns:
+- Fade animations (in/out)
+- Slide animations (up/down/left/right)
+- Scale animations (in/out)
+- Utility animations (spin, shimmer, shake, breathe, attention-pulse)
+- Toast/notification animations
+- Accessibility (@media prefers-reduced-motion)
+
+**Usage:** Copy this file to project and import in component styles or global styles:
+
+```css
+@import 'path/to/animations.css';
+```
+
+Then use classes directly:
+```html
+<div animate.enter="fade-in" animate.leave="slide-out-down">
+```
+
+## Migration from @angular/animations
+
+### Before (Angular Animations)
+
+```typescript
+import { trigger, state, style, transition, animate } from '@angular/animations';
+
+@Component({
+  animations: [
+    trigger('fadeIn', [
+      transition(':enter', [
+        style({ opacity: 0 }),
+        animate('300ms ease-out', style({ opacity: 1 }))
+      ])
+    ])
+  ]
+})
+```
+
+### After (CSS @keyframes)
+
+```typescript
+@Component({
+  template: `
+    @if (show()) {
+      <div animate.enter="fade-in">Content</div>
+    }
+  `,
+  styles: [`
+    .fade-in { animation: fadeIn 0.3s ease-out; }
+
+    @keyframes fadeIn {
+      from { opacity: 0; }
+      to { opacity: 1; }
+    }
+  `]
+})
+```
+
+**Benefits:**
+- Zero JavaScript bundle size (~60KB savings)
+- GPU hardware acceleration
+- Standard CSS (transferable skills)
+- Better performance

+# CSS @keyframes Deep Dive
+
+A comprehensive guide for Angular developers transitioning from `@angular/animations` to native CSS animations.

+
+---
+
+## Understanding @keyframes
+
+The `@keyframes` at-rule controls the intermediate steps in a CSS animation sequence by defining styles for keyframes (waypoints) along the animation. Unlike transitions (which only animate between two states), keyframes let you define multiple intermediate steps.
+
+### How It Differs from @angular/animations
+
+| @angular/animations | Native CSS @keyframes |
+|---------------------|----------------------|
+| ~60KB JavaScript bundle | Zero JS overhead |
+| CPU-based rendering | GPU hardware acceleration |
+| Angular-specific syntax | Standard CSS (transferable skills) |
+| `trigger()`, `state()`, `animate()` | `@keyframes` + CSS classes |
+
+---
+
+## Basic Syntax
+
+### The @keyframes Rule
+
+```css
+@keyframes animation-name {
+  from {
+    /* Starting styles (same as 0%) */
+  }
+  to {
+    /* Ending styles (same as 100%) */
+  }
+}
+```
+
+### Percentage-Based Keyframes
+
+For more control, use percentages to define multiple waypoints:
+
+```css
+@keyframes bounce {
+  0% {
+    transform: translateY(0);
+  }
+  25% {
+    transform: translateY(-30px);
+  }
+  50% {
+    transform: translateY(0);
+  }
+  75% {
+    transform: translateY(-15px);
+  }
+  100% {
+    transform: translateY(0);
+  }
+}
+```
+
+### Combining Multiple Percentages
+
+You can apply the same styles to multiple keyframes:
+
+```css
+@keyframes pulse {
+  0%, 100% {
+    opacity: 1;
+    transform: scale(1);
+  }
+  50% {
+    opacity: 0.7;
+    transform: scale(1.05);
+  }
+}
+```
+
+### Applying the Animation
+
+```css
+.element {
+  animation: bounce 1s ease-in-out infinite;
+}
+```
+
+---
+
+## Animation Properties
+
+### Individual Properties
+
+| Property | Description | Example |
+|----------|-------------|---------|
+| `animation-name` | Name of the @keyframes | `animation-name: bounce;` |
+| `animation-duration` | How long one cycle takes | `animation-duration: 2s;` |
+| `animation-timing-function` | Speed curve (easing) | `animation-timing-function: ease-in;` |
+| `animation-delay` | Wait before starting | `animation-delay: 500ms;` |
+| `animation-iteration-count` | How many times to run | `animation-iteration-count: 3;` or `infinite` |
+| `animation-direction` | Forward, reverse, or alternate | `animation-direction: alternate;` |
+| `animation-fill-mode` | Styles before/after animation | `animation-fill-mode: forwards;` |
+| `animation-play-state` | Pause or play | `animation-play-state: paused;` |
+
+### Shorthand Syntax
+
+```css
+/* animation: name duration timing-function delay iteration-count direction fill-mode play-state */
+.element {
+  animation: slideIn 0.5s ease-out 0.2s 1 normal forwards running;
+}
+```
+
+**Minimum required:** name and duration
+
+```css
+.element {
+  animation: fadeIn 1s;
+}
+```
+
+### Multiple Animations
+
+Apply multiple animations to a single element:
+
+```css
+.element {
+  animation:
+    fadeIn 0.5s ease-out,
+    slideUp 0.5s ease-out,
+    pulse 2s ease-in-out 0.5s infinite;
+}
+```
+
+---
+
+## Timing Functions (Easing)
+
+The timing function controls how the animation progresses over time—where it speeds up and slows down.
+
+### Keyword Values
+
+| Keyword | Cubic-Bezier Equivalent | Description |
+|---------|------------------------|-------------|
+| `linear` | `cubic-bezier(0, 0, 1, 1)` | Constant speed |
+| `ease` | `cubic-bezier(0.25, 0.1, 0.25, 1)` | Default: slow start, fast middle, slow end |
+| `ease-in` | `cubic-bezier(0.42, 0, 1, 1)` | Slow start, fast end |
+| `ease-out` | `cubic-bezier(0, 0, 0.58, 1)` | Fast start, slow end |
+| `ease-in-out` | `cubic-bezier(0.42, 0, 0.58, 1)` | Slow start and end |
+
+### Custom Cubic-Bezier
+
+Create custom easing curves with `cubic-bezier(x1, y1, x2, y2)`:
+
+```css
+/* Bouncy overshoot effect */
+.element {
+  animation-timing-function: cubic-bezier(0.68, -0.6, 0.32, 1.6);
+}
+
+/* Smooth deceleration */
+.element {
+  animation-timing-function: cubic-bezier(0.25, 1, 0.5, 1);
+}
+```
+
+**Tool:** Use [cubic-bezier.com](https://cubic-bezier.com) to visualize and create custom curves.
+
+### Popular Easing Functions
+
+```css
+/* Ease Out Quart - Great for enter animations */
+cubic-bezier(0.25, 1, 0.5, 1)
+
+/* Ease In Out Cubic - Smooth state changes */
+cubic-bezier(0.65, 0, 0.35, 1)
+
+/* Ease Out Back - Slight overshoot */
+cubic-bezier(0.34, 1.56, 0.64, 1)
+
+/* Ease In Out Back - Overshoot both ends */
+cubic-bezier(0.68, -0.6, 0.32, 1.6)
+```
+
+### Steps Function
+
+For frame-by-frame animations (like sprite sheets):
+
+```css
+/* 6 discrete steps */
+.sprite {
+  animation: walk 1s steps(6) infinite;
+}
+
+/* Step positions */
+steps(4, jump-start)  /* Jump at start of each interval */
+steps(4, jump-end)    /* Jump at end of each interval (default) */
+steps(4, jump-both)   /* Jump at both ends */
+steps(4, jump-none)   /* No jump at ends */
+```
+
+### Timing Function Per Keyframe
+
+Apply different easing to different segments:
+
+```css
+@keyframes complexMove {
+  0% {
+    transform: translateX(0);
+    animation-timing-function: ease-out;
+  }
+  50% {
+    transform: translateX(100px);
+    animation-timing-function: ease-in;
+  }
+  100% {
+    transform: translateX(200px);
+  }
+}
+```
+
+**Important:** The timing function applies to each step individually, not the entire animation.
+
+---
+
+## Fill Modes
+
+Fill modes control what styles apply before and after the animation runs.
+
+### Values
+
+| Value | Before Animation | After Animation |
+|-------|-----------------|-----------------|
+| `none` | Original styles | Original styles |
+| `forwards` | Original styles | **Last keyframe styles** |
+| `backwards` | **First keyframe styles** | Original styles |
+| `both` | **First keyframe styles** | **Last keyframe styles** |
+
+### Common Problem: Element Snaps Back
+
+```css
+/* BAD: Element disappears then reappears after animation */
+@keyframes fadeOut {
+  from { opacity: 1; }
+  to { opacity: 0; }
+}
+
+.element {
+  animation: fadeOut 1s; /* Element snaps back to opacity: 1 */
+}
+
+/* GOOD: Element stays invisible */
+.element {
+  animation: fadeOut 1s forwards;
+}
+```
+
+### Backwards Fill Mode (for delays)
+
+```css
+@keyframes slideIn {
+  from {
+    transform: translateX(-100%);
+    opacity: 0;
+  }
+  to {
+    transform: translateX(0);
+    opacity: 1;
+  }
+}
+
+/* Without backwards: element visible at original position during delay */
+/* With backwards: element starts at first keyframe position during delay */
+.element {
+  animation: slideIn 0.5s ease-out 1s backwards;
+}
+```
+
+---
+
+## Advanced Techniques
+
+### Animation Direction
+
+Control playback direction:
+
+```css
+animation-direction: normal;           /* 0% → 100% */
+animation-direction: reverse;          /* 100% → 0% */
+animation-direction: alternate;        /* 0% → 100% → 0% */
+animation-direction: alternate-reverse; /* 100% → 0% → 100% */
+```
+
+**Use Case:** Breathing/pulsing effects
+
+```css
+@keyframes breathe {
+  from { transform: scale(1); }
+  to { transform: scale(1.1); }
+}
+
+.element {
+  animation: breathe 2s ease-in-out infinite alternate;
+}
+```
+
+### Staggered Animations
+
+Create cascading effects with animation-delay:
+
+```css
+.item { animation: fadeSlideIn 0.5s ease-out backwards; }
+.item:nth-child(1) { animation-delay: 0ms; }
+.item:nth-child(2) { animation-delay: 100ms; }
+.item:nth-child(3) { animation-delay: 200ms; }
+.item:nth-child(4) { animation-delay: 300ms; }
+
+/* Or use CSS custom properties */
+.item {
+  animation: fadeSlideIn 0.5s ease-out backwards;
+  animation-delay: calc(var(--i, 0) * 100ms);
+}
+```
+
+In your template:
+
+```html
+<div class="item" style="--i: 0">First</div>
+<div class="item" style="--i: 1">Second</div>
+<div class="item" style="--i: 2">Third</div>
+```
+
+### @starting-style (Modern CSS)
+
+Define styles for when an element first enters the DOM:
+
+```css
+.modal {
+  opacity: 1;
+  transform: scale(1);
+  transition: opacity 0.3s, transform 0.3s;
+
+  @starting-style {
+    opacity: 0;
+    transform: scale(0.9);
+  }
+}
+```
+
+### Animating Auto Height
+
+Use CSS Grid for height: auto animations:
+
+```css
+.accordion-content {
+  display: grid;
+  grid-template-rows: 0fr;
+  transition: grid-template-rows 0.3s ease-out;
+}
+
+.accordion-content.open {
+  grid-template-rows: 1fr;
+}
+
+.accordion-content > div {
+  overflow: hidden;
+}
+```
+
+### Pause/Play with CSS
+
+```css
+.element {
+  animation: spin 2s linear infinite;
+  animation-play-state: running;
+}
+
+.element:hover {
+  animation-play-state: paused;
+}
+
+/* Or with a class */
+.element.paused {
+  animation-play-state: paused;
+}
+```
+
+---
+
+## Angular 20+ Integration
+
+### Using animate.enter and animate.leave
+
+Angular 20.2+ provides `animate.enter` and `animate.leave` to apply CSS classes when elements enter/leave the DOM.
+
+```typescript
+@Component({
+  selector: 'app-example',
+  template: `
+    @if (isVisible()) {
+      <div animate.enter="fade-in" animate.leave="fade-out">
+        Content here
+      </div>
+    }
+    <button (click)="toggle()">Toggle</button>
+  `,
+  styles: [`
+    .fade-in {
+      animation: fadeIn 0.3s ease-out;
+    }
+
+    .fade-out {
+      animation: fadeOut 0.3s ease-in;
+    }
+
+    @keyframes fadeIn {
+      from { opacity: 0; }
+      to { opacity: 1; }
+    }
+
+    @keyframes fadeOut {
+      from { opacity: 1; }
+      to { opacity: 0; }
+    }
+  `]
+})
+export class ExampleComponent {
+  isVisible = signal(false);
+  toggle() { this.isVisible.update(v => !v); }
+}
+```
+
+### Dynamic Animation Classes
+
+```typescript
+@Component({
+  template: `
+    @if (show()) {
+      <div [animate.enter]="enterAnimation()" [animate.leave]="leaveAnimation()">
+        Dynamic animations!
+      </div>
+    }
+  `
+})
+export class DynamicAnimComponent {
+  show = signal(false);
+  enterAnimation = signal('slide-in-right');
+  leaveAnimation = signal('slide-out-left');
+}
+```
+
+### Reusable Animation CSS File
+
+Create a shared `animations.css`:
+
+```css
+/* animations.css */
+
+/* Fade animations */
+.fade-in { animation: fadeIn 0.3s ease-out; }
+.fade-out { animation: fadeOut 0.3s ease-in; }
+
+@keyframes fadeIn {
+  from { opacity: 0; }
+  to { opacity: 1; }
+}
+
+@keyframes fadeOut {
+  from { opacity: 1; }
+  to { opacity: 0; }
+}
+
+/* Slide animations */
+.slide-in-up { animation: slideInUp 0.3s ease-out; }
+.slide-out-down { animation: slideOutDown 0.3s ease-in; }
+
+@keyframes slideInUp {

+
+## Common Patterns & Recipes
+
+### Loading Spinner
+
+```css
+@keyframes spin {
+  to { transform: rotate(360deg); }
+}
+
+.spinner {
+  width: 40px;
+  height: 40px;
+  border: 3px solid #f3f3f3;
+  border-top: 3px solid #3498db;
+  border-radius: 50%;
+  animation: spin 1s linear infinite;
+}
+```
+
+### Skeleton Loading
+
+```css
+@keyframes shimmer {
+  0% { background-position: -200% 0; }
+  100% { background-position: 200% 0; }
+}
+
+.skeleton {
+  background: linear-gradient(
+    90deg,
+    #f0f0f0 25%,
+    #e0e0e0 50%,
+    #f0f0f0 75%
+  );
+  background-size: 200% 100%;
+  animation: shimmer 1.5s infinite;
+}
+```
+
+### Attention Pulse
+
+```css
+@keyframes attention-pulse {
+  0%, 100% {
+    box-shadow: 0 0 0 0 rgba(59, 130, 246, 0.5);
+  }
+  50% {
+    box-shadow: 0 0 0 10px rgba(59, 130, 246, 0);
+  }
+}
+
+.notification-badge {
+  animation: attention-pulse 2s ease-in-out infinite;
+}
+```
+
+### Shake (Error Feedback)
+
+```css
+@keyframes shake {
+  0%, 100% { transform: translateX(0); }
+  10%, 30%, 50%, 70%, 90% { transform: translateX(-5px); }
+  20%, 40%, 60%, 80% { transform: translateX(5px); }
+}
+
+.error-input {
+  animation: shake 0.5s ease-in-out;
+}
+```
+
+### Slide Down Menu
+
+```css
+@keyframes slideDown {
+  from {
+    opacity: 0;
+    transform: translateY(-10px);
+  }
+  to {
+    opacity: 1;
+    transform: translateY(0);
+  }
+}
+
+.dropdown-menu {
+  animation: slideDown 0.2s ease-out forwards;
+}
+```
+
+### Toast Notification
+
+```css
+@keyframes toastIn {
+  from {
+    opacity: 0;
+    transform: translateY(100%) scale(0.9);
+  }
+  to {
+    opacity: 1;
+    transform: translateY(0) scale(1);
+  }
+}
+
+@keyframes toastOut {
+  from {
+    opacity: 1;
+    transform: translateY(0) scale(1);
+  }
+  to {
+    opacity: 0;
+    transform: translateY(100%) scale(0.9);
+  }
+}
+
+.toast {
+  animation: toastIn 0.3s cubic-bezier(0.34, 1.56, 0.64, 1);
+}
+
+.toast.leaving {
+  animation: toastOut 0.2s ease-in forwards;
+}
+```
+
+---
+
+## Performance Tips
+
+### Use Transform and Opacity
+
+These properties are GPU-accelerated and don't trigger layout:
+
+```css
+/* GOOD - GPU accelerated */
+@keyframes good {
+  from { transform: translateX(0); opacity: 0; }
+  to { transform: translateX(100px); opacity: 1; }
+}
+
+/* AVOID - Triggers layout recalculation */
+@keyframes avoid {
+  from { left: 0; width: 100px; }
+  to { left: 100px; width: 200px; }
+}
+```
+
+### Use will-change Sparingly
+
+```css
+.element {
+  will-change: transform, opacity;
+}
+
+/* Remove after animation */
+.element.animation-complete {
+  will-change: auto;
+}
+```
+
+### Respect Reduced Motion
+
+```css
+@keyframes fadeSlide {
+  from {
+    opacity: 0;
+    transform: translateY(20px);
+  }
+  to {
+    opacity: 1;
+    transform: translateY(0);
+  }
+}
+
+.element {
+  animation: fadeSlide 0.3s ease-out;
+}
+
+@media (prefers-reduced-motion: reduce) {
+  .element {
+    animation: none;
+    /* Or use a simpler fade */
+    animation: fadeIn 0.1s ease-out;
+  }
+}
+```
+
+### Avoid Animating Layout Properties
+
+Properties that trigger layout (reflow):
+
+- `width`, `height`
+- `top`, `left`, `right`, `bottom`
+- `margin`, `padding`
+- `font-size`
+- `border-width`
+
+Use `transform: scale()` instead of `width/height` when possible.
+
+---
+
+## Debugging Animations
+
+### Browser DevTools
+
+1. **Chrome DevTools** → More Tools → Animations
+   - Pause, slow down, or step through animations
+   - Inspect timing curves
+
+2. **Firefox** → Inspector → Animations tab
+   - Visual timeline of all animations
+
+### Force Slow Motion
+
+```css
+/* Temporarily add to debug */
+* {
+  animation-duration: 3s !important;
+}
+```
+
+### Animation Events in JavaScript
+
+```typescript
+element.addEventListener('animationstart', (e) => {
+  console.log('Started:', e.animationName);
+});
+
+element.addEventListener('animationend', (e) => {
+  console.log('Ended:', e.animationName);
+  // Clean up class, remove element, etc.
+});
+
+element.addEventListener('animationiteration', (e) => {
+  console.log('Iteration:', e.animationName);
+});
+```
+
+### Common Issues
+
+| Problem | Solution |
+|---------|----------|
+| Animation not running | Check `animation-duration` is > 0 |
+| Element snaps back | Add `animation-fill-mode: forwards` |
+| Animation starts wrong | Use `animation-fill-mode: backwards` with delay |
+| Choppy animation | Use `transform` instead of layout properties |
+| Animation restarts on state change | Ensure Angular doesn't recreate the element |
+
+---
+
+## Quick Reference Card
+
+```css
+/* Basic setup */
+@keyframes name {
+  from { /* start */ }
+  to { /* end */ }
+}
+
+.element {
+  animation: name 0.3s ease-out forwards;
+}
+
+/* Angular 20+ */
+<div animate.enter="fade-in" animate.leave="fade-out">
+
+/* Shorthand order */
+animation: name duration timing delay count direction fill-mode state;
+
+/* Common timing functions */
+ease-out: cubic-bezier(0, 0, 0.58, 1)      /* Enter animations */
+ease-in: cubic-bezier(0.42, 0, 1, 1)       /* Exit animations */
+ease-in-out: cubic-bezier(0.42, 0, 0.58, 1) /* State changes */
+
+/* Fill modes */
+forwards  → Keep end state
+backwards → Apply start state during delay
+both      → Both of the above
+```

----
-name: Git Commit Helper
-description: Generate descriptive commit messages by analyzing git diffs. Use when the user asks for help writing commit messages or reviewing staged changes.
----
-
-# Git Commit Helper
-
-## Quick start
-
-Analyze staged changes and generate commit message:
-
-```bash
-# View staged changes
-git diff --staged
-
-# Generate commit message based on changes
-# (Claude will analyze the diff and suggest a message)
-```
-
-## Commit message format
-
-Follow conventional commits format:
-
-```
-<type>(<scope>): <description>
-
-[optional body]
-
-[optional footer]
-```
-
-### Types
-
-- **feat**: New feature
-- **fix**: Bug fix
-- **docs**: Documentation changes
-- **style**: Code style changes (formatting, missing semicolons)
-- **refactor**: Code refactoring
-- **test**: Adding or updating tests
-- **chore**: Maintenance tasks
-
-### Examples
-
-**Feature commit:**
-```
-feat(auth): add JWT authentication
-
-Implement JWT-based authentication system with:
-- Login endpoint with token generation
-- Token validation middleware
-- Refresh token support
-```
-
-**Bug fix:**
-```
-fix(api): handle null values in user profile
-
-Prevent crashes when user profile fields are null.
-Add null checks before accessing nested properties.
-```
-
-**Refactor:**
-```
-refactor(database): simplify query builder
-
-Extract common query patterns into reusable functions.
-Reduce code duplication in database layer.
-```
-
-## Analyzing changes
-
-Review what's being committed:
-
-```bash
-# Show files changed
-git status
-
-# Show detailed changes
-git diff --staged
-
-# Show statistics
-git diff --staged --stat
-
-# Show changes for specific file
-git diff --staged path/to/file
-```
-
-## Commit message guidelines
-
-**DO:**
-- Use imperative mood ("add feature" not "added feature")
-- Keep first line under 50 characters
-- Capitalize first letter
-- No period at end of summary
-- Explain WHY not just WHAT in body
-
-**DON'T:**
-- Use vague messages like "update" or "fix stuff"
-- Include technical implementation details in summary
-- Write paragraphs in summary line
-- Use past tense
-
-## Multi-file commits
-
-When committing multiple related changes:
-
-```
-refactor(core): restructure authentication module
-
-- Move auth logic from controllers to service layer
-- Extract validation into separate validators
-- Update tests to use new structure
-- Add integration tests for auth flow
-
-Breaking change: Auth service now requires config object
-```
-
-## Scope examples
-
-**Frontend:**
-- `feat(ui): add loading spinner to dashboard`
-- `fix(form): validate email format`
-
-**Backend:**
-- `feat(api): add user profile endpoint`
-- `fix(db): resolve connection pool leak`
-
-**Infrastructure:**
-- `chore(ci): update Node version to 20`
-- `feat(docker): add multi-stage build`
-
-## Breaking changes
-
-Indicate breaking changes clearly:
-
-```
-feat(api)!: restructure API response format
-
-BREAKING CHANGE: All API responses now follow JSON:API spec
-
-Previous format:
-{ "data": {...}, "status": "ok" }
-
-New format:
-{ "data": {...}, "meta": {...} }
-
-Migration guide: Update client code to handle new response structure
-```
-
-## Template workflow
-
-1. **Review changes**: `git diff --staged`
-2. **Identify type**: Is it feat, fix, refactor, etc.?
-3. **Determine scope**: What part of the codebase?
-4. **Write summary**: Brief, imperative description
-5. **Add body**: Explain why and what impact
-6. **Note breaking changes**: If applicable
-
-## Interactive commit helper
-
-Use `git add -p` for selective staging:
-
-```bash
-# Stage changes interactively
-git add -p
-
-# Review what's staged
-git diff --staged
-
-# Commit with message
-git commit -m "type(scope): description"
-```
-
-## Amending commits
-
-Fix the last commit message:
-
-```bash
-# Amend commit message only
-git commit --amend
-
-# Amend and add more changes
-git add forgotten-file.js
-git commit --amend --no-edit
-```
-
-## Best practices
-
-1. **Atomic commits** - One logical change per commit
-2. **Test before commit** - Ensure code works
-3. **Reference issues** - Include issue numbers if applicable
-4. **Keep it focused** - Don't mix unrelated changes
-5. **Write for humans** - Future you will read this
-
-## Commit message checklist
-
-- [ ] Type is appropriate (feat/fix/docs/etc.)
-- [ ] Scope is specific and clear
-- [ ] Summary is under 50 characters
-- [ ] Summary uses imperative mood
-- [ ] Body explains WHY not just WHAT
-- [ ] Breaking changes are clearly marked
-- [ ] Related issue numbers are included

+name: git-workflow
+description: This skill should be used when creating branches, writing commits, or creating pull requests. Enforces ISA-Frontend Git conventions including feature/task-id-name branch format, conventional commits without co-author tags, and PRs targeting 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
+feature/praemie-checkout  # Missing task ID
+feature/5391_praemie      # Using underscores
+feature-5391-very-long-description-that-goes-on-forever  # Too long
+```
+
+### 3. Conventional Commits (WITHOUT Co-Author Tags)
+
+**Format**: `<type>(<scope>): <description>`
+
+**Types**:
+- `feat`: New feature
+- `fix`: Bug fix
+- `docs`: Documentation only
+- `style`: Code style (formatting, missing semicolons)
+- `refactor`: Code restructuring without feature changes
+- `perf`: Performance improvements
+- `test`: Adding or updating tests
+- `build`: Build system or dependencies
+- `ci`: CI configuration
+- `chore`: Maintenance tasks
+
+**Rules**:
+- ❌ **NO** "Generated with Claude Code" tags
+- ❌ **NO** "Co-Authored-By: Claude" tags
+- ✅ Keep first line under 72 characters
+- ✅ Use imperative mood ("add" not "added")
+- ✅ Body optional but recommended for complex changes
+
+**Examples**:
+```bash
+# Good
+feat(checkout): add bonus card selection for delivery orders
+
+fix(crm): resolve customer search filter reset issue
+
+refactor(oms): extract return validation logic into service
+
+# Bad
+feat(checkout): add bonus card selection
+
+Generated with Claude Code
+Co-Authored-By: Claude <noreply@anthropic.com>
+
+# Also bad
+Added new feature  # Wrong tense
+Fix bug            # Missing scope
+```
+
+### 4. Pull Request Creation
+
+**Target Branch**: Always `develop`
+
+**PR Title Format**: Same as conventional commit
+```
+feat(domain): concise description of changes
+```
+
+**PR Body Structure**:
+```markdown
+## Summary
+- Brief bullet points of changes
+
+## Related Tasks
+- Closes #{task-id}
+- Refs #{related-task}
+
+## Test Plan
+- [ ] Unit tests added/updated
+- [ ] E2E attributes added
+- [ ] Manual testing completed
+
+## Breaking Changes
+None / List breaking changes
+
+## Screenshots (if UI changes)
+[Add screenshots]
+```
+
+## Common Workflows
+
+### Creating a Feature Branch
+
+```bash
+# 1. Update develop
+git checkout develop
+git pull origin develop
+
+# 2. Create feature branch
+git checkout -b feature/5391-praemie-checkout-action-card
+
+# 3. Work and commit
+git add .
+git commit -m "feat(checkout): add primary bonus card selection logic"
+
+# 4. Push to remote
+git push -u origin feature/5391-praemie-checkout-action-card
+
+# 5. Create PR targeting develop (use gh CLI or web UI)
+```
+
+### Creating a Bugfix Branch
+
+```bash
+# From develop
+git checkout develop
+git pull origin develop
+git checkout -b bugfix/6123-login-redirect-loop
+
+# Commit
+git commit -m "fix(auth): resolve infinite redirect on logout"
+```
+
+### Creating a Hotfix Branch
+
+```bash
+# From main (production)
+git checkout main
+git pull origin main
+git checkout -b hotfix/7890-payment-processing-error
+
+# Commit
+git commit -m "fix(checkout): critical payment API timeout handling"
+
+# Merge to both main and develop
+```
+
+## Commit Message Guidelines
+
+### Good Commit Messages
+
+```bash
+feat(crm): add customer loyalty tier calculation
+
+Implements three-tier loyalty system based on annual spend.
+Includes migration for existing customer data.
+
+Refs #5234
+
+---
+
+fix(oms): prevent duplicate return submissions
+
+Adds debouncing to return form submission and validates
+against existing returns in the last 60 seconds.
+
+Closes #5891
+
+---
+
+refactor(catalogue): extract product search into dedicated service
+
+Moves search logic from component to ProductSearchService
+for better testability and reusability.
+
+---
+
+perf(remission): optimize remission list query with pagination
+
+Reduces initial load time from 3s to 800ms by implementing
+cursor-based pagination.
+
+Closes #6234
+```
+
+### Bad Commit Messages
+
+```bash
+# Too vague
+fix: bug fixes
+
+# Missing scope
+feat: new feature
+
+# Wrong tense
+fixed the login issue
+
+# Including banned tags
+feat(checkout): add feature
+
+Generated with Claude Code
+Co-Authored-By: Claude <noreply@anthropic.com>
+```
+
+## Git Configuration Checks
+
+### Verify Git Setup
+
+```bash
+# Check current branch
+git branch --show-current
+
+# Verify remote
+git remote -v  # Should show origin pointing to ISA-Frontend
+
+# Check for uncommitted changes
+git status
+```
+
+## Common Mistakes to Avoid
+
+```bash
+# ❌ Creating PR against main
+gh pr create --base main  # WRONG
+
+# ✅ Always target develop
+gh pr create --base develop  # CORRECT
+
+# ❌ Using underscores in branch names
+git checkout -b feature/5391_my_feature  # WRONG
+
+# ✅ Use hyphens
+git checkout -b feature/5391-my-feature  # CORRECT
+
+# ❌ Adding co-author tags
+git commit -m "feat: something
+
+Co-Authored-By: Claude <noreply@anthropic.com>"  # WRONG
+
+# ✅ Clean commit message
+git commit -m "feat(scope): something"  # CORRECT
+
+# ❌ Forgetting task ID in branch name
+git checkout -b feature/new-checkout-flow  # WRONG
+
+# ✅ Include task ID
+git checkout -b feature/5391-new-checkout-flow  # CORRECT
+```
+
+## Integration with Claude Code
+
+When Claude Code creates commits or PRs:
+
+### Commit Creation
+```bash
+# Claude uses conventional commits WITHOUT attribution
+git commit -m "feat(checkout): implement bonus card selection
+
+Adds logic for selecting primary bonus card during checkout
+for delivery orders. Includes validation and error handling.
+
+Refs #5391"
+```
+
+### PR Creation
+```bash
+# Target develop by default
+gh pr create --base develop \
+  --title "feat(checkout): implement bonus card selection" \

+
+# 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
+- **[logging](../logging/SKILL.md)** - MANDATORY logging in all Angular components using `@isa/core/logging`
+
+## 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

+### Lists and Tables
+
+```html
+<!-- Dynamic List with @for -->
+<ul data-what="product-list" data-which="catalog">
+  @for (product of products; track product.id) {
+    <li

+<div
+  *ngIf="showDialog"
+  data-what="confirmation-dialog"
+  data-which="delete-item">
+
+  <h2>Confirm Deletion</h2>
+  <p>Are you sure you want to delete this item?</p>

+  <div data-what="dialog-content" data-which="welcome">
+    <h2>Welcome!</h2>
+    <p>Thank you for joining us.</p>
+  </div>
+</div>
+```
+
+## 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">

+}
+
+<!-- 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`

+- [ ] 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">

+name: ngrx-resource-api
+description: This skill should be used when implementing Angular's Resource API with NgRx Signal Store for reactive data management. Use when creating signal stores that load data reactively, need automatic race condition prevention, or require declarative resource management without RxJS. Applies to data-access libraries, feature stores with API integration, and components needing reactive filtering or pagination.
+---
+
+# NgRx Resource API
+
+## Overview
+
+This skill enables integration of Angular's Resource API with NgRx Signal Store to create reactive data flows without RxJS while automatically preventing race conditions. The Resource API handles concurrent request management declaratively, eliminating manual `switchMap` or `takeUntilDestroyed` patterns.
+
+## Core Architectural Concepts
+
+### Reactive Flow Graph
+
+Establish three clear interaction points in the store:
+
+1. **Filter signals trigger resource loading** - Parameter changes automatically reload resources
+2. **Methods explicitly invoke operations** - Use `signalMethod` for user-triggered actions
+3. **Computed signals derive view models** - Transform loaded data for component consumption
+
+### The withProps Pattern for Dependency Injection
+
+Inject services via `withProps` with underscore-prefixed properties to mark them as internal implementation details:
+
+```typescript
+withProps(() => ({
+  _dataService: inject(DataService),
+  _notificationService: inject(ToastService),
+}))
+```
+
+**Benefits:**
+- Centralizes dependency injection in one location
+- Clear distinction between internal (prefixed) and public properties
+- Services available to all subsequent feature sections
+
+## Implementation Steps
+
+### Step 1: Inject Services with withProps
+
+Create the initial `withProps` section to inject required services:
+
+```typescript
+export const MyStore = signalStore(
+  withProps(() => ({
+    _dataService: inject(DataService),
+    _toastService: inject(ToastService),
+  })),
+  // ... additional features
+);
+```
+
+**Naming convention:** Prefix all injected services with underscore (`_`) to indicate internal use.
+
+### Step 2: Define Filter State
+
+Add state properties that will serve as resource parameters:
+
+```typescript
+withState({
+  filter: {
+    searchTerm: '',
+    category: '',
+  } as MyFilter,
+})
+```
+
+### Step 3: Configure Resources
+
+In a subsequent `withProps` section, create resources that reference the injected services and state:
+
+```typescript
+withProps((store) => ({
+  _itemsResource: resource({
+    params: store.filter,
+    loader: (loaderParams) => {
+      const filter = loaderParams.params;
+      const abortSignal = loaderParams.abortSignal;
+      return store._dataService.loadItems(filter, abortSignal);
+    }
+  })
+}))
+```
+
+**Key points:**
+- Resources automatically reload when `params` signal changes
+- `abortSignal` enables automatic cancellation of in-flight requests
+- Loader must return a Promise (use `.findPromise()` if service returns Observable)
+
+### Step 4: Expose Read-Only Resources (Optional)
+
+If the resource should be accessible to consumers, expose it as read-only:
+
+```typescript
+withProps((store) => ({
+  itemsResource: store._itemsResource.asReadonly(),
+}))
+```
+
+**Pattern:** Internal resources use underscore prefix, public versions are read-only without prefix.
+
+### Step 5: Create Signal Methods for Updates
+
+Use `signalMethod` for actions that update state and trigger resource reloads:
+
+```typescript
+withMethods((store) => ({
+  updateFilter: signalMethod<MyFilter>((filter) => {
+    patchState(store, { filter });
+  }),
+
+  refresh: () => {
+    store._itemsResource.reload();
+  }
+}))
+```
+
+**Important:** `signalMethod` implementations are **untracked by convention** - they don't re-execute when signals change. This provides explicit control flow.
+
+### Step 6: Add Error Handling
+
+Use `withHooks` to react to resource errors:
+
+```typescript
+withHooks({
+  onInit: (store) => {
+    effect(() => {
+      const error = store._itemsResource.error();
+      if (error) {
+        store._toastService.show('Error: ' + getMessage(error));
+      }
+    });
+  }
+})
+```
+
+**Pattern:** Error effects should be read-only - they observe errors and trigger side effects, but don't modify state.
+
+## Common Patterns
+
+### Template Integration with linkedSignal
+
+For two-way form binding that synchronizes with the store:
+
+```typescript
+export class MyComponent {
+  #store = inject(MyStore);
+
+  // Create linked signal for form field
+  searchTerm = linkedSignal(() => this.#store.filter().searchTerm);
+
+  // Combine form fields into filter object
+  #linkedFilter = computed(() => ({
+    searchTerm: this.searchTerm(),
+    // ... other fields
+  }));
+
+  constructor() {
+    // Sync form changes back to store
+    this.#store.updateFilter(this.#linkedFilter);
+  }
+}
+```
+
+**Benefits:**
+- Two-way binding for forms
+- Automatic store synchronization
+- Type-safe filter construction
+
+### Working with Resource Data
+
+Access resource data through resource signals:
+
+```typescript
+withComputed((store) => ({
+  items: computed(() => store._itemsResource.value() ?? []),
+  isLoading: computed(() => store._itemsResource.isLoading()),
+  hasError: computed(() => store._itemsResource.hasError()),
+}))
+```
+
+**Available signals:**
+- `value()` - The loaded data (undefined while loading)
+- `isLoading()` - Loading state boolean
+- `hasError()` - Error state boolean
+- `error()` - Error object if present
+- `status()` - Overall status: 'idle' | 'loading' | 'resolved' | 'error'
+
+### Updating Resource Data Locally
+
+For temporary working copies before server writes:
+
+```typescript
+withMethods((store) => ({
+  updateLocalItem: (id: string, changes: Partial<Item>) => {
+    store._itemsResource.update((currentItems) => {
+      return currentItems.map(item =>
+        item.id === id ? { ...item, ...changes } : item
+      );
+    });
+  }
+}))
+```
+
+**Note:** This pattern feels unconventional but aligns with maintaining temporary working copies before server persistence.
+
+### Multiple Resources in One Store
+
+Combine multiple resources for complex data requirements:
+
+```typescript
+withProps((store) => ({
+  _itemsResource: resource({
+    params: store.filter,
+    loader: (params) => store._dataService.loadItems(params.params, params.abortSignal)
+  }),
+
+  _detailsResource: resource({
+    params: store.selectedId,
+    loader: (params) => {
+      if (!params.params) return Promise.resolve(null);
+      return store._dataService.loadDetails(params.params, params.abortSignal);
+    }
+  })
+}))
+```
+
+**Pattern:** Each resource has independent params and loading state, but can share service instances.
+
+## Important Considerations
+
+### Race Condition Prevention
+
+The Resource API automatically handles race conditions:
+- New requests automatically cancel pending requests
+- No need for `switchMap`, `takeUntilDestroyed`, or manual abort handling
+- Declarative parameter changes trigger clean cancellation
+
+### Untracked Signal Methods
+
+`signalMethod` implementations deliberately skip reactive tracking:
+- Provides explicit, predictable control flow
+- Prevents unexpected re-executions from signal changes
+- Makes side effects obvious at call sites
+
+### Loader Function Requirements
+
+Loaders must:
+- Return a `Promise` (not Observable)
+- Accept and pass through the `abortSignal` to enable cancellation
+- Handle the signal in the underlying HTTP call
+
+**Converting Observables:**
+```typescript
+loader: (params) => {
+  return firstValueFrom(
+    this._service.load$(params.params)
+      .pipe(takeUntilDestroyed(this._destroyRef))
+  );
+}
+```
+
+### Resource Lifecycle
+
+Resources maintain their own state machine:
+1. **Idle** - Initial state before first load
+2. **Loading** - Request in progress
+3. **Resolved** - Data loaded successfully
+4. **Error** - Request failed
+
+State transitions automatically trigger reactive updates to dependent computeds and effects.
+
+## When to Use This Pattern
+
+**Use Resource API with Signal Store when:**
+- Loading data based on reactive filter/search parameters
+- Need automatic race condition handling for concurrent requests
+- Want declarative data loading without RxJS subscriptions
+- Building stores with frequently changing query parameters
+- Implementing pagination, filtering, or search features
+
+**Consider alternatives when:**
+- Simple one-time data loads (use `rxMethod` or direct service calls)
+- Complex Observable chains with multiple operators needed
+- Need fine-grained control over request timing/caching
+- Working with WebSocket or SSE streams (use `rxMethod` instead)

+### Jest Config → Vitest Config
+
+**Before (jest.config.ts):**
+```typescript
+export default {
+  displayName: 'my-lib',
+  preset: '../../jest.preset.js',
+  setupFilesAfterEnv: ['<rootDir>/src/test-setup.ts'],
+  coverageDirectory: '../../coverage/libs/my-lib',

+  snapshotSerializers: [
+    'jest-preset-angular/build/serializers/no-ng-attributes',
+    'jest-preset-angular/build/serializers/ng-snapshot',
+  ],
+};
+```
+
+**After (vitest.config.ts):**
+```typescript
+import { defineConfig } from 'vitest/config';
+import angular from '@analogjs/vite-plugin-angular';
+
+export default defineConfig({
+  plugins: [angular()],
+  test: {
+    globals: true,
+    environment: 'jsdom',
+    setupFiles: ['src/test-setup.ts'],
+    include: ['**/*.spec.ts'],

+    coverage: {
+      provider: 'v8',
+      reporter: ['text', 'json', 'html'],
+    },
+  },
+});
+```
+
+### Test Setup Migration
+
+**Before (test-setup.ts - Jest):**
+```typescript
+import 'jest-preset-angular/setup-jest';
+```
+
+**After (test-setup.ts - Vitest):**
+```typescript
+import '@analogjs/vitest-angular/setup-zone';
+```
+
+## Import Changes
+
+### Test Function Imports
+
+**Before (Jest):**
+```typescript
+import { describe, it, expect, beforeEach, afterEach } from '@jest/globals';
+```
+
+**After (Vitest):**
+```typescript
+import { describe, it, expect, beforeEach, afterEach, vi } from 'vitest';
+```
+
+### Mock Imports
+
+**Before (Jest):**
+```typescript
+jest.fn()
+jest.spyOn()
+jest.mock()
+jest.useFakeTimers()
+```
+
+**After (Vitest):**
+```typescript
+vi.fn()
+vi.spyOn()
+vi.mock()
+vi.useFakeTimers()
+```
+
+## Mock Migration Patterns
+
+### Function Mocks
+
+**Before (Jest):**
+```typescript
+const mockFn = jest.fn();
+const mockFnWithReturn = jest.fn().mockReturnValue('value');
+const mockFnWithAsync = jest.fn().mockResolvedValue('async value');
+```
+
+**After (Vitest):**
+```typescript
+const mockFn = vi.fn();
+const mockFnWithReturn = vi.fn().mockReturnValue('value');
+const mockFnWithAsync = vi.fn().mockResolvedValue('async value');
+```
+
+### Spy Migration
+
+**Before (Jest):**
+```typescript
+const spy = jest.spyOn(service, 'method');
+spy.mockImplementation(() => 'mocked');
+```
+
+**After (Vitest):**
+```typescript
+const spy = vi.spyOn(service, 'method');
+spy.mockImplementation(() => 'mocked');
+```
+
+### Module Mocks
+
+**Before (Jest):**
+```typescript
+jest.mock('@isa/core/logging', () => ({
+  logger: jest.fn(() => ({
+    info: jest.fn(),
+    error: jest.fn(),
+  })),
+}));
+```
+
+**After (Vitest):**
+```typescript
+vi.mock('@isa/core/logging', () => ({
+  logger: vi.fn(() => ({
+    info: vi.fn(),
+    error: vi.fn(),
+  })),
+}));
+```
+
+## Spectator → Angular Testing Library
+
+### Component Testing
+
+**Before (Spectator):**
+```typescript

+    expect(spectator.query('.title')).toHaveText('Hello');
+  });
+
+  it('should handle click', () => {
+    spectator.click('.button');
+    expect(mockService.doSomething).toHaveBeenCalled();
+  });
+});
+```
+
+**After (Angular Testing Library):**
+```typescript
+import { render, screen, fireEvent } from '@testing-library/angular';
+
+describe('MyComponent', () => {
+  it('should render title', async () => {
+    await render(MyComponent, {
+      imports: [CommonModule],
+      providers: [
+        { provide: MyService, useValue: mockService },
+      ],
+    });
+
+    expect(screen.getByText('Hello')).toBeInTheDocument();
+  });
+
+  it('should handle click', async () => {
+    await render(MyComponent, {
+      providers: [{ provide: MyService, useValue: mockService }],
+    });
+
+    fireEvent.click(screen.getByRole('button'));
+    expect(mockService.doSomething).toHaveBeenCalled();
+  });
+});
+```
+
+### Query Selectors
+
+| Spectator | Angular Testing Library |
+|-----------|------------------------|
+| `spectator.query('.class')` | `screen.getByTestId()` or `screen.getByRole()` |
+| `spectator.queryAll('.class')` | `screen.getAllByRole()` |
+| `spectator.query('button')` | `screen.getByRole('button')` |
+| `spectator.query('[data-testid]')` | `screen.getByTestId()` |
+
+### Events
+
+| Spectator | Angular Testing Library |
+|-----------|------------------------|
+| `spectator.click(element)` | `fireEvent.click(element)` or `await userEvent.click(element)` |
+| `spectator.typeInElement(value, element)` | `await userEvent.type(element, value)` |
+| `spectator.blur(element)` | `fireEvent.blur(element)` |
+| `spectator.focus(element)` | `fireEvent.focus(element)` |
+
+### Service Testing
+
+**Before (Spectator):**
+```typescript
+import { createServiceFactory, SpectatorService } from '@ngneat/spectator/jest';
+
+describe('MyService', () => {
+  let spectator: SpectatorService<MyService>;
+  const createService = createServiceFactory({
+    service: MyService,

+
+  beforeEach(() => {
+    spectator = createService();
+  });
+
+  it('should fetch data', () => {
+    spectator.service.getData().subscribe(data => {
+      expect(data).toEqual(expectedData);
+    });
+  });
+});
+```
+
+**After (TestBed):**
+```typescript
+import { TestBed } from '@angular/core/testing';
+
+describe('MyService', () => {
+  let service: MyService;
+
+  beforeEach(() => {
+    TestBed.configureTestingModule({
+      providers: [
+        MyService,
+        { provide: HttpClient, useValue: mockHttp },
+      ],
+    });
+    service = TestBed.inject(MyService);
+  });
+
+  it('should fetch data', () => {
+    service.getData().subscribe(data => {
+      expect(data).toEqual(expectedData);
+    });
+  });
+});
+```
+
+## Async Testing
+
+### Observable Testing
+
+**Before (Jest):**
+```typescript
+it('should emit values', (done) => {
+  service.data$.subscribe({
+    next: (value) => {
+      expect(value).toBe(expected);
+      done();
+    },
+  });
+});
+```
+
+**After (Vitest):**
+```typescript
+import { firstValueFrom } from 'rxjs';
+
+it('should emit values', async () => {
+  const value = await firstValueFrom(service.data$);
+  expect(value).toBe(expected);
+});
+```
+
+### Timer Mocks
+
+**Before (Jest):**
+```typescript
+jest.useFakeTimers();
+service.startTimer();
+jest.advanceTimersByTime(1000);
+expect(callback).toHaveBeenCalled();
+jest.useRealTimers();
+```
+
+**After (Vitest):**
+```typescript
+vi.useFakeTimers();
+service.startTimer();
+vi.advanceTimersByTime(1000);
+expect(callback).toHaveBeenCalled();
+vi.useRealTimers();
+```
+
+## Common Matchers
+
+| Jest | Vitest |
+|------|--------|
+| `expect(x).toBe(y)` | Same |
+| `expect(x).toEqual(y)` | Same |
+| `expect(x).toHaveBeenCalled()` | Same |
+| `expect(x).toHaveBeenCalledWith(y)` | Same |
+| `expect(x).toMatchSnapshot()` | `expect(x).toMatchSnapshot()` |
+| `expect(x).toHaveText('text')` | `expect(x).toHaveTextContent('text')` (with jest-dom) |

+# Zod Patterns Reference
+
+## Overview
+
+Zod is a TypeScript-first schema validation library. Use it for runtime validation at system boundaries (API responses, form inputs, external data).
+
+## Basic Schema Patterns
+
+### Primitive Types
+
+```typescript
+import { z } from 'zod';
+
+// Basic types
+const stringSchema = z.string();
+const numberSchema = z.number();
+const booleanSchema = z.boolean();
+const dateSchema = z.date();
+
+// With constraints
+const emailSchema = z.string().email();
+const positiveNumber = z.number().positive();
+const nonEmptyString = z.string().min(1);
+const optionalString = z.string().optional();
+const nullableString = z.string().nullable();
+```
+
+### Object Schemas
+
+```typescript
+// Basic object
+const userSchema = z.object({
+  id: z.string().uuid(),
+  email: z.string().email(),
+  name: z.string().min(1),
+  age: z.number().int().positive().optional(),
+  role: z.enum(['admin', 'user', 'guest']),
+  createdAt: z.string().datetime(),
+});
+
+// Infer TypeScript type from schema
+type User = z.infer<typeof userSchema>;
+
+// Partial and Pick utilities
+const partialUser = userSchema.partial();           // All fields optional
+const requiredUser = userSchema.required();         // All fields required
+const pickedUser = userSchema.pick({ email: true, name: true });
+const omittedUser = userSchema.omit({ createdAt: true });
+```
+
+### Array Schemas
+
+```typescript
+// Basic array
+const stringArray = z.array(z.string());
+
+// With constraints
+const nonEmptyArray = z.array(z.string()).nonempty();
+const limitedArray = z.array(z.number()).min(1).max(10);
+
+// Tuple (fixed length, different types)
+const coordinate = z.tuple([z.number(), z.number()]);
+```
+
+## API Response Validation
+
+### Pattern: Validate API Responses
+
+```typescript
+// Define response schema
+const apiResponseSchema = z.object({
+  data: z.object({
+    items: z.array(userSchema),
+    total: z.number(),
+    page: z.number(),
+    pageSize: z.number(),
+  }),
+  meta: z.object({
+    timestamp: z.string().datetime(),
+    requestId: z.string().uuid(),
+  }),
+});
+
+// In Angular service
+@Injectable({ providedIn: 'root' })
+export class UserService {
+  #http = inject(HttpClient);
+  #logger = logger({ component: 'UserService' });
+
+  getUsers(): Observable<User[]> {
+    return this.#http.get('/api/users').pipe(
+      map((response) => {
+        const result = apiResponseSchema.safeParse(response);
+        if (!result.success) {
+          this.#logger.error('Invalid API response', {
+            errors: result.error.errors
+          });
+          throw new Error('Invalid API response');
+        }
+        return result.data.data.items;
+      })
+    );
+  }
+}
+```
+
+### Pattern: Coerce Types
+
+```typescript
+// API returns string IDs, coerce to number
+const productSchema = z.object({
+  id: z.coerce.number(),           // "123" -> 123
+  price: z.coerce.number(),        // "99.99" -> 99.99
+  inStock: z.coerce.boolean(),     // "true" -> true
+  createdAt: z.coerce.date(),      // "2024-01-01" -> Date
+});
+```
+
+## Form Validation
+
+### Pattern: Form Schema
+
+```typescript
+// Define form schema with custom error messages
+const loginFormSchema = z.object({
+  email: z.string()
+    .email({ message: 'Invalid email address' }),
+  password: z.string()
+    .min(8, { message: 'Password must be at least 8 characters' })
+    .regex(/[A-Z]/, { message: 'Must contain uppercase letter' })
+    .regex(/[0-9]/, { message: 'Must contain number' }),
+  rememberMe: z.boolean().default(false),
+});
+
+// Use with Angular forms
+type LoginForm = z.infer<typeof loginFormSchema>;
+```
+
+### Pattern: Cross-field Validation
+
+```typescript
+const passwordFormSchema = z.object({
+  password: z.string().min(8),
+  confirmPassword: z.string(),
+}).refine(
+  (data) => data.password === data.confirmPassword,
+  {
+    message: "Passwords don't match",
+    path: ['confirmPassword'], // Error path
+  }
+);
+```
+
+## Type Guards
+
+### Pattern: Create Type Guard from Schema
+
+```typescript
+// Schema
+const customerSchema = z.object({
+  type: z.literal('customer'),
+  customerId: z.string(),
+  loyaltyPoints: z.number(),
+});
+
+// Type guard function
+function isCustomer(value: unknown): value is z.infer<typeof customerSchema> {
+  return customerSchema.safeParse(value).success;
+}
+
+// Usage
+if (isCustomer(data)) {
+  console.log(data.loyaltyPoints); // Type-safe access
+}
+```
+
+### Pattern: Discriminated Unions
+
+```typescript
+const customerSchema = z.object({
+  type: z.literal('customer'),
+  customerId: z.string(),
+});
+
+const guestSchema = z.object({
+  type: z.literal('guest'),
+  sessionId: z.string(),
+});
+
+const userSchema = z.discriminatedUnion('type', [
+  customerSchema,
+  guestSchema,
+]);
+
+type User = z.infer<typeof userSchema>;
+// User = { type: 'customer'; customerId: string } | { type: 'guest'; sessionId: string }
+```
+
+## Replacing `any` Types
+
+### Before (unsafe)
+
+```typescript
+function processOrder(order: any) {
+  // No type safety
+  console.log(order.items.length);
+  console.log(order.customer.name);
+}
+```
+
+### After (with Zod)
+
+```typescript
+const orderSchema = z.object({
+  id: z.string().uuid(),
+  items: z.array(z.object({
+    productId: z.string(),
+    quantity: z.number().positive(),
+    price: z.number().nonnegative(),
+  })),
+  customer: z.object({
+    name: z.string(),
+    email: z.string().email(),
+  }),
+  status: z.enum(['pending', 'confirmed', 'shipped', 'delivered']),
+});
+
+type Order = z.infer<typeof orderSchema>;
+
+function processOrder(input: unknown): Order {
+  const order = orderSchema.parse(input); // Throws if invalid
+  console.log(order.items.length);        // Type-safe
+  console.log(order.customer.name);       // Type-safe
+  return order;
+}
+```
+
+## Error Handling
+
+### Pattern: Structured Error Handling
+
+```typescript
+const result = schema.safeParse(data);
+
+if (!result.success) {
+  // Access formatted errors
+  const formatted = result.error.format();
+
+  // Access flat error list
+  const flat = result.error.flatten();
+
+  // Custom error mapping
+  const errors = result.error.errors.map(err => ({
+    field: err.path.join('.'),
+    message: err.message,
+    code: err.code,
+  }));
+}
+```
+
+## Transform Patterns
+
+### Pattern: Transform on Parse
+
+```typescript
+const userInputSchema = z.object({
+  email: z.string().email().transform(s => s.toLowerCase()),
+  name: z.string().transform(s => s.trim()),
+  tags: z.string().transform(s => s.split(',')),
+});
+
+// Input: { email: "USER@EXAMPLE.COM", name: "  John  ", tags: "a,b,c" }
+// Output: { email: "user@example.com", name: "John", tags: ["a", "b", "c"] }
+```
+
+### Pattern: Default Values
+
+```typescript
+const configSchema = z.object({
+  theme: z.enum(['light', 'dark']).default('light'),
+  pageSize: z.number().default(20),
+  features: z.array(z.string()).default([]),
+});
+```
+
+## Best Practices
+
+1. **Define schemas at module boundaries** - API services, form handlers
+2. **Use `safeParse` for error handling** - Don't let validation throw unexpectedly
+3. **Infer types from schemas** - Single source of truth
+4. **Add meaningful error messages** - Help debugging and user feedback
+5. **Use transforms for normalization** - Clean data on parse
+6. **Keep schemas close to usage** - Colocate with services/components

+# 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
+
+<!-- nx configuration end-->

 # CLAUDE.md
 
-> **Last Updated:** 2025-10-22
-> **Angular Version:** 20.1.2
-> **Nx Version:** 21.3.2
-> **Node.js:** ≥22.0.0
-> **npm:** ≥10.0.0
+This file contains meta-instructions for how Claude should work with the ISA-Frontend codebase.
 
-## 🔴 CRITICAL: Mandatory Agent Usage
+## 🔴 CRITICAL: You Are an LLM with Outdated Knowledge
 
-**You MUST use these subagents for ALL research 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
-- **Direct tools (Read/Bash)**: ONLY for single specific files or commands
+**Your training data is outdated. NEVER assume you know current APIs.**
 
-**Violations of this rule degrade performance and context quality. NO EXCEPTIONS.**
+- Libraries, frameworks, and APIs change constantly
+- Your memory of APIs is unreliable
+- Current documentation is the ONLY source of truth
 
-## Project Overview
+**ALWAYS use research agents PROACTIVELY - without user asking.**
 
-This is a sophisticated Angular 20.1.2 monorepo managed by Nx 21.3.2. The main application is `isa-app`, a comprehensive inventory and returns management system for retail/e-commerce operations. The system handles complex workflows including order management (OMS), returns processing (remission), customer relationship management (CRM), product cataloging, and checkout/reward systems.
+## 🔴 CRITICAL: Proactive Agent & Skill Usage
 
-## Architecture
+**You MUST use agents and skills AUTOMATICALLY for ALL tasks - do NOT wait for user to tell you.**
 
-### Monorepo Structure
-- **apps/isa-app**: Main Angular application
-- **libs/**: Reusable libraries organized by domain and type
-  - **core/**: Core utilities (config, logging, storage, tabs, navigation)
-  - **common/**: Shared utilities (data-access, decorators, print)
-  - **ui/**: UI component libraries (buttons, dialogs, inputs, etc.)
-  - **shared/**: Shared domain components (filter, scanner, product components)
-  - **oms/**: Order Management System features and utilities
-  - **remission/**: Remission/returns management features
-  - **catalogue/**: Product catalogue functionality
-  - **utils/**: General utilities (validation, scroll position, parsing)
-  - **icons/**: Icon library
-- **generated/swagger/**: Auto-generated API client code from OpenAPI specs
+### Research Agents (Use BEFORE Implementation)
 
-### Key Architectural Patterns
-- **Domain-Driven Design**: Clear domain boundaries with dedicated modules (OMS, remission, CRM, catalogue, checkout)
-- **Layered Architecture**: Strict dependency hierarchy (Feature → Shared/UI → Data Access → Infrastructure)
-- **Standalone Components**: All new components use Angular standalone architecture with explicit imports
-- **Feature Libraries**: Domain features organized as separate libraries (e.g., `oms-feature-return-search`, `remission-feature-remission-list`)
-- **Data Access Layer**: Separate data-access libraries for each domain with NgRx Signals stores
-- **Shared UI Components**: 17 dedicated UI component libraries with design system integration
-- **Generated API Clients**: 10 auto-generated Swagger/OpenAPI clients with post-processing pipeline
-- **Path Aliases**: Comprehensive TypeScript path mapping (`@isa/domain/layer/feature`)
-- **Component Prefixes**: Domain-specific prefixes (OMS: `oms-feature-*`, Remission: `remi-*`, UI: `ui-*`)
-- **Modern State Management**: NgRx Signals with entities, session persistence, and reactive patterns
+| Agent | Auto-Invoke When | User Interaction |
+|-------|------------------|------------------|
+| `docs-researcher` | ANY external library/API usage | NONE - just do it |
+| `docs-researcher-advanced` | Implementation fails OR docs-researcher insufficient | NONE - just do it |
+| `Explore` | Need codebase patterns or multi-file analysis | NONE - just do it |

+**Research-First Flow (Mandatory):**
+```
+Task involves external API? → AUTO-INVOKE docs-researcher
+                              ↓
+                              Implement based on docs
+                              ↓
+                              Failed? → AUTO-INVOKE docs-researcher-advanced
+                              ↓
+                              Still failed? → ASK USER for guidance
 ```
 
-### Standard Nx Commands
-For complete command reference, see [Nx Documentation](https://nx.dev/reference/commands).
+### Skills (Use DURING Implementation)
 
-**Common patterns:**
-```bash
-# Test specific library (always use --skip-nx-cache)
-npx nx test <project-name> --skip-nx-cache
+| Trigger | Auto-Invoke Skill |
+|---------|-------------------|
+| Writing Angular templates | `angular-template` |
+| Writing HTML with interactivity | `html-template` |
+| Applying Tailwind classes | `tailwind` |
+| Writing any Angular code | `logging` |
+| Creating CSS animations | `css-keyframes-animations` |
+| Creating new library | `library-scaffolder` |
+| Regenerating API clients | `swagger-sync-manager` |
+| Git operations | `git-workflow` |
 
-# Lint a project
-npx nx lint <project-name>
-
-# Show project dependencies
-npx nx graph
-
-# Run tests for affected projects (CI/CD)
-npx nx affected:test --skip-nx-cache
+**Skill chaining for Angular work:**
+```
+angular-template → html-template → logging → tailwind
 ```
 
-**Important:** Always use `--skip-nx-cache` flag when running tests to ensure fresh results.
+### Implementation Agents (Use for Complex Tasks)
 
-## Testing Framework
+| Agent | Auto-Invoke When |
+|-------|------------------|
+| `angular-developer` | Creating components, services, stores (2-5 files) |
+| `test-writer` | Writing tests, adding coverage |
+| `refactor-engineer` | Refactoring 5+ files, migrations |
 
-> **Last Reviewed:** 2025-10-22
-> **Status:** Migration in Progress (Jest → Vitest)
+### Anti-Patterns (FORBIDDEN)
 
-### Current Setup (Migration in Progress)
-- **Jest**: 40 libraries (65.6% - legacy/existing code)
-- **Vitest**: 21 libraries (34.4% - new standard)
-- All formal libraries now have test executors configured
-
-### Testing Strategy
-- **New libraries**: Use Vitest + Angular Testing Utilities (TestBed, ComponentFixture)
-- **Legacy libraries**: Continue with Jest + Spectator until migrated
-- **Advanced mocking**: Use ng-mocks for complex scenarios
-
-### Key Requirements
-- Test files must end with `.spec.ts`
-- Use AAA pattern (Arrange-Act-Assert)
-- **Always include E2E attributes**: `data-what`, `data-which`, and dynamic `data-*` in HTML templates
-- Mock external dependencies appropriately for your framework
-
-**For detailed testing guidelines, framework comparison, and migration instructions, see [`docs/guidelines/testing.md`](docs/guidelines/testing.md).**

-**References:**
-- [Jest Documentation](https://jestjs.io/)
-- [Vitest Documentation](https://vitest.dev/)
-- [Angular Testing Guide](https://angular.io/guide/testing)
-- [Spectator](https://ngneat.github.io/spectator/)
-
-## State Management
-- **NgRx Signals**: Primary state management with modern functional approach using `signalStore()`
-- **Entity Management**: Uses `withEntities()` for normalized data storage
-- **Session Persistence**: State persistence with `withStorage()` using SessionStorageProvider
-- **Reactive Methods**: `rxMethod()` with `takeUntilKeydownEscape()` for user-cancellable operations
-- **Custom RxJS Operators**: Specialized operators like `takeUntilAborted()`, `takeUntilKeydown()`
-- **Error Handling**: `tapResponse()` for handling success/error states in stores
-- **Lifecycle Hooks**: `withHooks()` for cleanup and initialization (e.g., orphaned entity cleanup)
-- **Navigation State**: Use `@isa/core/navigation` for temporary navigation context (return URLs, wizard state) instead of query parameters
-
-## Styling and Design System
-- **Framework**: [Tailwind CSS](https://tailwindcss.com/docs) with extensive ISA-specific customization
-- **Custom Breakpoints**: `isa-desktop` (1024px), `isa-desktop-l` (1440px), `isa-desktop-xl` (1920px)
-- **Brand Color System**: `isa-*` color palette with semantic naming
-- **Custom Tailwind Plugins** (7): button, typography, menu, label, input, section, select-bullet
-- **Typography System**: 14 custom utilities (`.isa-text-heading-1-bold`, `.isa-text-body-2-regular`, etc.)
-- **UI Component Libraries**: 17 specialized libraries with consistent APIs (see Library Reference)
-- **Storybook**: Component documentation and development at `npm run storybook`
-
-### Responsive Design with Breakpoint Service
-Use `@isa/ui/layout` for reactive breakpoint detection instead of CSS-only solutions:
-
-```typescript
-import { breakpoint, Breakpoint } from '@isa/ui/layout';
-
-// Detect screen size reactively
-isDesktop = breakpoint([Breakpoint.Desktop, Breakpoint.DekstopL, Breakpoint.DekstopXL]);
+```
+❌ Implementing without researching first
+❌ Asking "should I research this?" - just do it
+❌ Asking "should I use a skill?" - just do it
+❌ Trial and error: implement → fail → try again → fail
+❌ Writing Angular code without loading skills first
 ```
 
-**Available Breakpoints:**
-- `Tablet`: max-width: 1279px (mobile/tablet)
-- `Desktop`: 1280px - 1439px (standard desktop)
-- `DekstopL`: 1440px - 1919px (large desktop)
-- `DekstopXL`: 1920px+ (extra large)
+### Correct Pattern
 
-**Template Usage:**
-```html
-@if (isDesktop) {
-  <!-- Desktop-specific content -->
-}
+```
+✅ "Researching [library] API..." → [auto-invokes docs-researcher]
+✅ "Loading angular-template skill..." → [auto-invokes skill]
+✅ "Implementing based on current docs..."
+✅ If fails: "Escalating research..." → [auto-invokes docs-researcher-advanced]
 ```
 
-**Why:** Prefer breakpoint service over CSS-only (hidden/flex) for SSR and maintainability.
+## Communication Guidelines
 
-## API Integration and Data Access
+- Keep answers concise and focused
+- Use bullet points and structured formatting
+- Skip verbose explanations unless requested
+- Focus on what the user needs, not everything you know
 
-**Generated Swagger Clients:** 10 auto-generated TypeScript clients in `generated/swagger/`
-- Available APIs: availability-api, cat-search-api, checkout-api, crm-api, eis-api, inventory-api, isa-api, oms-api, print-api, wws-api
-- Tool: [ng-swagger-gen](https://www.npmjs.com/package/ng-swagger-gen) with custom per-API configuration
-- Post-processing: Automatic Unicode cleanup via `tools/fix-files.js`
-- Regenerate: `npm run generate:swagger`
+## Context Management
 
-**Architecture Pattern:**
-- Business logic services wrap generated API clients
-- Type safety: TypeScript + [Zod](https://zod.dev/) schema validation
-- Error handling: Global HTTP interceptor with automatic re-authentication
-- Modern injection: Uses `inject()` function with private field pattern
-- Request cancellation: Built-in via AbortSignal and custom RxJS operators (`takeUntilAborted()`, `takeUntilKeydown()`)
+**Context bloat kills reliability. Minimize aggressively.**
 
-**Data Access Libraries:** See Library Reference section for domain-specific implementations (`@isa/[domain]/data-access`).
+### Tool Result Minimization
 
-## Build Configuration
-- **Framework**: Angular with TypeScript (see `package.json` for current versions)
-- **Requirements**:
-  - Node.js >= 22.0.0 (specified in package.json engines)
-  - npm >= 10.0.0 (specified in package.json engines)
-- **Build System**: Nx monorepo with Vite for testing (Vitest)
-- **Development Server**: Serves with SSL by default (required for authentication flows)
+| Tool | Keep | Discard |
+|------|------|---------|
+| Bash (success) | `✓ Command succeeded` | Full output |
+| Bash (failure) | Exit code + error (max 10 lines) | Verbose output |
+| Edit | `✓ Modified file.ts` | Full diffs |
+| Read | Extracted relevant section | Full file content |
+| Agent results | 1-2 sentence summary | Raw JSON/full output |
 
-## Important Conventions and Patterns
+### Agent Result Handling
 
-### Library Organization
-- **Naming Pattern**: `[domain]-[layer]-[feature]` (e.g., `oms-feature-return-search`, `ui-buttons`)
-- **Path Aliases**: `@isa/[domain]/[layer]/[feature]` (e.g., `@isa/oms/data-access`, `@isa/ui/buttons`)
-- **Project Names**: Found in each library's `project.json` file, following consistent naming
+```
+❌ WRONG: "Docs researcher returned: [huge JSON...]"
+✅ RIGHT: "docs-researcher found: Use signalStore() with withState()"
+```
 
-### Component Architecture
-- **Standalone Components**: All new components must be standalone with explicit imports
-- **Component Prefixes**: Domain-specific prefixes for clear identification
-  - OMS features: `oms-feature-*` (e.g., `oms-feature-return-search-main`)
-  - Remission features: `remi-*`
-  - UI components: `ui-*`
-  - Core utilities: `core-*`
-- **Signal-based Inputs**: Use Angular signals (`input()`, `computed()`) for reactive properties
-- **Host Binding**: Dynamic CSS classes via Angular host properties
+### Session Cleanup
 
-### Dependency Rules
-- **Unidirectional Dependencies**: Feature → Shared/UI → Data Access → Infrastructure
-- **Import Boundaries**: Use path aliases, avoid relative imports across domain boundaries
-- **Generated API Imports**: Import from `@generated/swagger/[api-name]` for API clients
+Use `/clear` between unrelated tasks to prevent context degradation.
 
-### Code Quality
-- **Modern Angular Patterns**: Prefer `inject()` over constructor injection
-- **Type Safety**: Use Zod schemas for runtime validation alongside TypeScript
-- **Error Handling**: Custom error classes with specific error codes
-- **E2E Testing**: Always include `data-what` and `data-which` attributes in templates
+### Long-Running Task Pattern
 
-## Development Workflow and Best Practices
+For complex tasks approaching context limits:
+1. Dump progress to a `.md` file (e.g., `progress.md`)
+2. Use `/clear` to reset context
+3. Resume by reading the progress file
+4. Continue from where you left off
 
-### Project Conventions
-- **Default Branch**: `develop` (not main) - Always create PRs against develop
-- **Branch Naming**: When starting work on a new feature or bug, create a branch following this pattern:
-  - Format: `feature/{task-id}-{short-description}` or `bugfix/{task-id}-{short-description}`
-  - Use English kebab-case for the description
-  - Start with the task/issue ID (e.g., `5391`)
-  - Keep description concise - shorten if the full title is too long
-  - Example: For task "#5391 Prämie Checkout // Action Card - Versandbestellung"
-    - Branch: `feature/5391-praemie-checkout-action-card-delivery-order`
-- **Commit Style**: [Conventional commits](https://www.conventionalcommits.org/) without co-author tags
-- **Nx Cache**: Always use `--skip-nx-cache` for tests to ensure fresh results
-- **Testing**: New libraries use Vitest + Angular Testing Utilities; legacy use Jest + Spectator
-- **E2E Attributes**: Always include `data-what`, `data-which`, and dynamic `data-*` in templates
-- **Design System**: Use ISA-specific Tailwind utilities (`isa-accent-*`, `isa-text-*`)
+### Context Monitoring
 
-### Code Quality Tools
-- **Linting**: [ESLint](https://eslint.org/) with Nx dependency checks
-- **Formatting**: [Prettier](https://prettier.io/) with Husky + lint-staged pre-commit hooks
-- **Type Safety**: [TypeScript](https://www.typescriptlang.org/) strict mode + [Zod](https://zod.dev/) validation
-- **Bundle Size**: Monitor carefully (2MB warning, 5MB error for main bundle)
+- Use `/context` to check current token usage
+- Fresh session baseline: ~20k tokens
+- Consider `/compact` when approaching 150k tokens
+- Prefer `/clear` over `/compact` when starting new topics
 
-### Nx Workflow Tips
-- Use `npx nx graph` to visualize dependencies
-- Use `npx nx affected:test` for CI/CD optimization
-- Reference: [Nx Documentation](https://nx.dev/getting-started/intro)
+## Extended Thinking
 
-## Development Notes and Guidelines
+Use progressive thinking depth for complex analysis:
 
-### Getting Started
-- **Application Startup**: Only `isa-app` can be started - it's the main application entry point
-- **SSL Development**: The development server runs with SSL by default (`npm start`), which is crucial for production-like authentication flows
-- **Node Requirements**: Ensure Node.js ≥22.0.0 and npm ≥10.0.0 before starting development
-- **First-Time Setup**: After cloning, run `npm install` then `npm start` to verify everything works
+| Trigger | Thinking Budget | Use Case |
+|---------|----------------|----------|
+| `"think"` | ~4k tokens | Basic analysis, simple decisions |
+| `"think hard"` | ~10k tokens | Moderate complexity, multi-factor decisions |
+| `"think harder"` | ~16k tokens | Deep analysis, architectural decisions |
+| `"ultrathink"` | ~32k tokens | Maximum depth, critical planning |
 
-### Essential Documentation References
-- **Testing Guidelines**: Review `docs/guidelines/testing.md` before writing any tests - it covers the Jest→Vitest migration, Spectator→Angular Testing Utilities transition, and E2E attribute requirements
-- **Code Review Standards**: Follow the structured review process in `.github/review-instructions.md` with categorized feedback (🚨 Critical, ❗ Minor, ⚠️ Warnings, ✅ Good Practices)
-- **E2E Testing Requirements**: Always include `data-what`, `data-which`, and dynamic `data-*` attributes in HTML templates - these are essential for automated testing by QA colleagues
+**Examples:**
+- "Think about how to structure this component"
+- "Think hard about the best approach for state management"
+- "Ultrathink about the architecture for this feature"
 
-### Researching and Investigating the Codebase
+## Code Investigation (MANDATORY)
 
-**🔴 MANDATORY: You MUST use subagents for research. Direct file reading/searching is FORBIDDEN except for single specific files.**
+**Never speculate about code you haven't read.**
 
-#### Required Agent Usage
+If user references a specific file:
+1. **READ the file first** using the Read tool
+2. **THEN provide analysis** based on actual contents
+3. If file doesn't exist, **say so explicitly**
+
+**Anti-Hallucination Rules:**
+- Never describe code you haven't opened
+- Never assume file contents based on names
+- Never guess API signatures without documentation
+- Always verify imports and dependencies exist
+
+## Implementation Decisions
 
 | Task Type                         | Required Agent     | Escalation Path                           |

-#### Documentation Research System (Two-Tier)
+**Note:** The `docs-researcher` agent uses `docs/library-reference.md` as a primary index for discovering monorepo libraries. This file contains descriptions and locations for all libraries, enabling quick library discovery without reading individual READMEs.
+
+### 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:

 ```
-❌ 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"
+Single known file? → Read tool directly
+Code pattern search? → Explore agent
+Documentation lookup? → docs-researcher agent
+Creating 2-5 Angular files? → angular-developer agent
+Refactoring 5+ files? → refactor-engineer agent
+Simple 1-file edit? → Direct implementation
 ```
 
-**Remember: Using subagents is NOT optional - it's mandatory for maintaining context efficiency and search quality.**
+### Proactive Agent Triggers
 
-#### Common Research Patterns
+**Auto-invoke `angular-developer` when user says:**
+- "Create component/service/store/pipe/directive/guard"
+- Task touches 2-5 Angular files
 
-| Information Need | Required Approach |
-|-----------------|-------------------|
-| **Library documentation** | `docs-researcher` → Check library-reference.md → Escalate if needed |
-| **Code patterns/examples** | `Explore` with "medium" or "very thorough" |
-| **Architecture understanding** | `npx nx graph` + `Explore` for implementation |
-| **Debugging/errors** | Direct tool use (Read specific error file, check console) |
+**Auto-invoke `test-writer` when user says:**
+- "Write tests", "Add coverage"
 
-#### Debugging Tips
-- **TypeScript errors**: Follow error path to exact file:line
-- **Test failures**: Use `--skip-nx-cache` for fresh output
-- **Module resolution**: Check `tsconfig.base.json` path aliases
-- **State issues**: Use Angular DevTools browser extension
+**Auto-invoke `refactor-engineer` when user says:**
+- "Refactor all", "Migrate X files", "Update pattern across"
 
-### Library Development Patterns
-- **Library Documentation**: Use `docs-researcher` for ALL library READMEs (mandatory for context management)
-- **New Library Creation**: Use Nx generators with domain-specific naming (`[domain]-[layer]-[feature]`)
-- **Standalone Components**: All new components must be standalone with explicit imports - no NgModules
-- **Testing Framework**: New = Vitest + Angular Testing Utilities, Legacy = Jest + Spectator
-- **Path Aliases**: Always use `@isa/[domain]/[layer]/[feature]` - avoid relative imports
+**Auto-invoke `context-manager` when user says:**
+- "Remember to", "TODO:", "Don't forget"
 
-#### Library Reference Guide
+## Agent Communication
 
-The monorepo contains **62 libraries** organized across 12 domains. For quick lookup, see **[`docs/library-reference.md`](docs/library-reference.md)**.
+### Briefing Agents
 
-**Quick Overview by Domain:**
-- 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)
+Keep briefings focused:
+```
+Implement: [type] at [path]
+Purpose: [1 sentence]
+Requirements: [list]
+```
 
-### API Integration Workflow
-- **Swagger Generation**: Run `npm run generate:swagger` to regenerate all 10 API clients when backend changes
-- **Data Services**: Wrap generated API clients in domain-specific data-access services with proper error handling and Zod validation
-- **State Management**: Use NgRx Signals with `signalStore()`, entity management, and session persistence for complex state
+### Agent Results
 
-### Performance and Quality Considerations
-- **Bundle Monitoring**: Watch bundle sizes (2MB warning, 5MB error for main bundle)
-- **Testing Cache**: Always use `--skip-nx-cache` flag when running tests to ensure reliable results
-- **Code Quality**: Pre-commit hooks enforce Prettier formatting and ESLint rules automatically
-- **Memory Management**: Clean up subscriptions and use OnPush change detection for optimal performance
+Extract only what's needed, discard the rest:
+```
+✓ Created 3 files
+✓ Tests: 12/12 passing
+✓ Skills applied: angular-template, logging
+```
 
-### Common Troubleshooting
-- **Build Issues**: Check Node version and run `npm install` if encountering module resolution errors
-- **Test Failures**: Use `--skip-nx-cache` flag and ensure test isolation (no shared state between tests)
-- **Nx Cache Issues**: If you see `existing outputs match the cache, left as is` during build or testing:
-  - **Option 1**: Run `npx nx reset` to clear the Nx cache completely
-  - **Option 2**: Use `--skip-nx-cache` flag to bypass Nx cache for a specific command (e.g., `npx nx test <project> --skip-nx-cache`)
-  - **When to use**: Always use `--skip-nx-cache` when you need guaranteed fresh builds or test results
-- **SSL Certificates**: Development server uses SSL - accept certificate warnings in browser for localhost
-- **Import Errors**: Verify path aliases in `tsconfig.base.json` and use absolute imports for cross-library dependencies
+<!-- nx configuration start-->
+<!-- Leave the start & end comments to automatically receive updates. -->
 
-### Domain-Specific Conventions
-- **Component Prefixes**: Use `oms-feature-*` for OMS, `remi-*` for remission, `ui-*` for shared components
-- **Git Workflow**: Default branch is `develop` (not main), use conventional commits without co-author tags
-- **Design System**: Use ISA-specific Tailwind utilities (`isa-accent-*`, `isa-text-*`) and custom breakpoints (`isa-desktop-*`)
-- **Logging**: Use centralized logging service (`@isa/core/logging`) with contextual information for debugging
-- **Navigation State**: Use `@isa/core/navigation` for passing temporary state between routes (return URLs, form context) instead of query parameters - keeps URLs clean and state reliable
+# General Guidelines for working with Nx
+
+- Run tasks through `nx` (i.e. `nx run`, `nx run-many`, `nx affected`) instead of underlying tooling
+- Use `nx_workspace` tool to understand workspace architecture
+- Use `nx_project_details` for specific project structure

+ * Domain service for managing the complete checkout flow including shopping cart operations,
+ * checkout creation, buyer/payer management, payment processing, and order completion.
+ *
+ * This service orchestrates interactions between:
+ * - NgRx Store for state management
+ * - Multiple Swagger API clients (checkout, OMS, shopping cart, payment, buyer, payer, branch, kulturpass)
+ * - Shopping cart event system for cross-component synchronization
+ * - Availability service for real-time product availability checks
+ *
+ * @remarks
+ * **Process ID Pattern**: All methods require a `processId` (typically `Date.now()`) to isolate
+ * checkout sessions. Multiple concurrent checkout processes can run independently.
+ *
+ * **Observable-First Design**: Most methods return Observables for reactive composition. Consumers
+ * should use RxJS operators for transformation and error handling.
+ *
+ * **Auto-Creation**: Shopping carts auto-create if missing. The service uses `filter()` operators
+ * to trigger lazy initialization and prevent race conditions.
+ *
+ * **Event Sourcing**: Publishes shopping cart events (Created, ItemAdded, ItemUpdated, ItemRemoved)
+ * for synchronization across components. Subscribes to events from `ShoppingCartService` to maintain
+ * consistency.
+ *
+ * **OLA Management**: Tracks Order Level Agreement (OLA) expiration timestamps per item and order type.
+ * Validates availability freshness before checkout completion.
+ *
+ * @example
+ * ```typescript
+ * // Basic shopping cart flow
+ * const processId = Date.now();
+ *
+ * // Add items to cart
+ * this.checkoutService.addItemToShoppingCart({
+ *   processId,
+ *   items: [{ productId: 123, quantity: 2 }]
+ * }).subscribe();
+ *
+ * // Get cart (auto-creates if missing)
+ * this.checkoutService.getShoppingCart({ processId })
+ *   .subscribe(cart => console.log(cart));
+ *
+ * // Complete checkout (orchestrates all steps)
+ * this.checkoutService.completeCheckout({ processId })
+ *   .subscribe(orders => console.log('Orders created:', orders));
