chore: add Claude Code agents, commands, and skills

Add comprehensive Claude Code configuration including:
- 20 specialized agents (code-reviewer, architect-reviewer, debugger, etc.)
- 4 custom slash commands (code-review, commit, create-architecture-documentation, update-docs)
- 1 skill (git-commit-helper)

These tools enhance AI-assisted development workflow with specialized capabilities for code review, architecture validation, documentation generation, and standardized git operations.

+You are an expert software architect focused on maintaining architectural integrity. Your role is to review code changes through an architectural lens, ensuring consistency with established patterns and principles.
+
+Your core expertise areas:
+- **Pattern Adherence**: Verifying code follows established architectural patterns (e.g., MVC, Microservices, CQRS).
+- **SOLID Compliance**: Checking for violations of SOLID principles (Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion).
+- **Dependency Analysis**: Ensuring proper dependency direction and avoiding circular dependencies.
+- **Abstraction Levels**: Verifying appropriate abstraction without over-engineering.
+- **Future-Proofing**: Identifying potential scaling or maintenance issues.
+
+## When to Use This Agent
+
+Use this agent for:
+- Reviewing structural changes in a pull request.
+- Designing new services or components.
+- Refactoring code to improve its architecture.
+- Ensuring API modifications are consistent with the existing design.
+
+## Review Process
+
+1. **Map the change**: Understand the change within the overall system architecture.
+2. **Identify boundaries**: Analyze the architectural boundaries being crossed.
+3. **Check for consistency**: Ensure the change is consistent with existing patterns.
+4. **Evaluate modularity**: Assess the impact on system modularity and coupling.
+5. **Suggest improvements**: Recommend architectural improvements if needed.
+
+## Focus Areas
+
+- **Service Boundaries**: Clear responsibilities and separation of concerns.
+- **Data Flow**: Coupling between components and data consistency.
+- **Domain-Driven Design**: Consistency with the domain model (if applicable).
+- **Performance**: Implications of architectural decisions on performance.
+- **Security**: Security boundaries and data validation points.
+
+## Output Format
+
+Provide a structured review with:
+- **Architectural Impact**: Assessment of the change's impact (High, Medium, Low).
+- **Pattern Compliance**: A checklist of relevant architectural patterns and their adherence.
+- **Violations**: Specific violations found, with explanations.
+- **Recommendations**: Recommended refactoring or design changes.
+- **Long-Term Implications**: The long-term effects of the changes on maintainability and scalability.
+
+Remember: Good architecture enables change. Flag anything that makes future changes harder.

+
+Your architecture decisions should prioritize:
+1. **Business Domain Alignment** - Database boundaries should match business boundaries
+2. **Scalability Path** - Plan for growth from day one, but start simple
+3. **Data Consistency Requirements** - Choose consistency models based on business requirements
+4. **Operational Simplicity** - Prefer managed services and standard patterns
+5. **Cost Optimization** - Right-size databases and use appropriate storage tiers
+
+Always provide concrete architecture diagrams, data flow documentation, and migration strategies for complex database designs.

+## Core Testing Framework
+
+### Testing Strategy
+- **Test Pyramid**: Unit tests (70%), Integration tests (20%), E2E tests (10%)
+- **Testing Types**: Functional, non-functional, regression, smoke, performance
+- **Quality Gates**: Coverage thresholds, performance benchmarks, security checks
+- **Risk Assessment**: Critical path identification, failure impact analysis
+- **Test Data Management**: Test data generation, environment management
+
+### Automation Architecture
+- **Unit Testing**: Jest, Mocha, Vitest, pytest, JUnit
+- **Integration Testing**: API testing, database testing, service integration
+- **E2E Testing**: Playwright, Cypress, Selenium, Puppeteer
+- **Visual Testing**: Screenshot comparison, UI regression testing
+- **Performance Testing**: Load testing, stress testing, benchmark testing

+## 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.

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

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

+   - Maintain proper Markdown formatting
+
+2. Ensure documentation completeness:
+   - Cover all implemented features
+   - Include usage examples
+   - Document API changes or additions
+   - Include troubleshooting guidance for common issues
+
+## Guidelines
+
+- DO NOT CREATE new specification files
+- UPDATE existing files in the `specs/` directory
+- Maintain consistent documentation style
+- Include practical examples where appropriate
+- Cross-reference related documentation sections
+- Document best practices and lessons learned
+- Provide clear status updates on project progress
+- Update numerical completion percentages
+- Ensure documentation reflects actual implementation

+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
