| description | Keep documentation in sync with code changes. Use when implementing features, modifying APIs, changing architecture, adding configuration, updating security, or making any changes that affect user-facing or developer-facing documentation. |
Documentation Synchronization Skill
Overview
This skill ensures documentation in the docs/ directory remains synchronized with codebase changes, maintaining accuracy and completeness for both users and developers.
Core Principle
Documentation is part of the definition of done. No code change is complete until the relevant documentation is updated.
When to Use This Skill
Activate this skill when:
- API Changes: Adding/modifying REST or GraphQL endpoints
- Database Changes: Adding entities, modifying schema
- Architecture Changes: Changing design patterns, component structure
- Configuration Changes: Adding environment variables, config options
- Security Changes: Modifying authentication, authorization
- Testing Changes: Adding test strategies, new test types
- Performance Changes: Optimizations, benchmarking
- Feature Implementation: New user-facing features

Documentation Update Workflow
Quick Reference
For each code change:
- Identify Impact: Which docs need updates?
- Update Content: Follow scenario-specific patterns
- Cross-Reference: Ensure links remain valid
- Validate Examples: Test all code samples
- Review Checklist: Use pre-commit checklist

Documentation Quality Standards
Consistency
- ✅ Follow existing doc structure and formatting
- ✅ Use terminology from
docs/glossary.md - ✅ Include code examples with syntax highlighting
- ✅ Add cross-references to related sections
Completeness
- ✅ Document all public APIs and endpoints
- ✅ Include error handling and edge cases
- ✅ Provide basic and advanced examples
- ✅ Update version info when needed
Maintenance
- ✅ Remove outdated information
- ✅ Update release notes for significant changes
- ✅ Validate all links and references
- ✅ Update diagrams if architecture changes
See detailed standards: reference/quality-standards.md
Pre-Commit Checklist
Before committing code with documentation updates:
- Identify Impact: Determine which docs need updates
- Update Content: Apply scenario-specific patterns
- Cross-Reference: Verify all links remain valid
- Test Examples: Run all code examples
- Check Consistency: Verify terminology matches glossary
- Update Specs: Run
make generate-openapi-specormake generate-graphql-specif needed - Review Changes: Ensure completeness and accuracy
See complete workflow: reference/workflow-checklist.md
Integration with Development
During Development
Documentation is code:
- Update docs in same PR as code changes
- Test documentation examples
- Validate links and references
During Code Review
Reviewers check:
- Documentation accuracy
- Completeness of examples
- Terminology consistency
- Link validity
During CI/CD
Automated checks:
- Documentation links validation
- Example code syntax checking
- Spec generation and validation
