# Constitution Update Summary ## Version Information - **Previous Version**: 1.0.0 - **New Version**: 1.1.0 - **Version Bump Rationale**: MINOR - Added new principle (Prefer Existing Solutions) and updated tooling specification (Biome) - **Ratification Date**: 2025-10-12 - **Last Amended**: 2025-10-12 ## Latest Changes (v1.1.0) ### Modified Principles **Code Quality Standards (Principle I)** - CHANGED: Tooling from Prettier/ESLint to **Biome** - Biome provides fast, unified linting and formatting with zero configuration conflicts - All code must pass Biome checks before commit ### New Principles **Prefer Existing Solutions (Principle VI)** - MUST search for existing packages/libraries before writing custom code - MUST use Context7 MCP to find official examples and patterns - Custom implementations require written justification - Reused code must include attribution - Prefer battle-tested solutions over custom implementations **Rationale**: Reduces bugs, maintenance burden, and development time. Existing solutions are typically better tested and documented. ## Changes Made ### Initial Version (v1.0.0) #### New Principles Added 1. **Code Quality Standards (Principle I)** - Type safety requirements (TypeScript strict mode) - Code style enforcement (initially Prettier/ESLint, now Biome) - Modularity standards - Documentation requirements - Error handling mandates 2. **Testing Standards (Principle II) - NON-NEGOTIABLE** - Test-first development (TDD) mandatory - 80% minimum code coverage requirement - Unit, integration, and contract test requirements - Test quality standards - Continuous testing via CI/CD 3. **User Experience Consistency (Principle III)** - Interface consistency requirements - Response time targets (200ms sync, 2s complex) - User-friendly error messages - WCAG 2.1 Level AA accessibility standards - Progressive enhancement strategy 4. **Documentation-First Development (Principle IV)** - **Context7 MCP requirement for all external dependencies** - Architecture Decision Records (ADR) required - API documentation via OpenAPI/Swagger - User documentation completeness - Code comment standards 5. **Dependency Hygiene (Principle V)** - **Latest stable versions required for all dependencies** - Security audit requirements - Minimal dependency philosophy - License compatibility verification - Monthly dependency review cycle 6. **Prefer Existing Solutions (Principle VI)** - NEW in v1.1.0 - Search for existing packages before custom code - Use Context7 MCP for official examples - Justify custom implementations - Document code attribution - Prefer battle-tested solutions ### New Sections Added - **Development Standards**: Code review, branch strategy, commit standards - **Quality Gates**: Pre-merge and pre-release checklists - **Governance**: Amendment process, version semantics, compliance, enforcement ## Template Updates ### ✅ Updated Files 1. **`.specify/memory/constitution.md`** - Replaced all placeholders with concrete principles - Added comprehensive governance section - Included sync impact report as HTML comment 2. **`.specify/templates/plan-template.md`** - Updated Constitution Check section with specific checklist items - Added items for all 6 principles - Included Biome tooling requirement - Added Principle VI checklist items - Included violation justification requirement ### ✅ Verified Compatible (No Changes Needed) 3. **`.specify/templates/spec-template.md`** - Already compatible with UX consistency requirements - User story format supports test-first development - Success criteria format supports quality standards 4. **`.specify/templates/tasks-template.md`** - Test-first task ordering already enforced - Phase structure supports quality gates - Documentation tasks appropriately positioned ## Key Requirements for Teams ### Critical Requirements 1. **Always use Context7 MCP** to retrieve latest documentation before implementing features with external dependencies 2. **Always use latest stable package versions** unless explicitly justified 3. **Search for existing solutions first** before writing custom code 4. **Test-first development is non-negotiable** - tests must be written before implementation 5. **80% code coverage minimum** for all new features 6. **TypeScript strict mode** with no unjustified `any` types 7. **Use Biome** for all linting and formatting ### Quality Gates All features must pass: - Code review approval - All automated tests (unit, integration, contract) - Biome checks (linting and formatting) - Security scans - 80% minimum code coverage - Documentation completeness - Constitution compliance check - Existing solutions evaluated (for new functionality) ### Amendment Process To amend the constitution: 1. Create proposal with rationale 2. Minimum 1-week discussion period 3. Achieve team consensus 4. Update version following semantic versioning 5. Update all dependent templates 6. Communicate changes to team ## Suggested Commit Message ``` docs: update constitution to v1.1.0 (Biome tooling + prefer existing solutions) - Update Principle I: Replace Prettier/ESLint with Biome for unified linting/formatting - Add Principle VI: Prefer Existing Solutions over custom implementations - Require evaluation of existing packages before writing custom code - Mandate Context7 MCP usage to find official examples and patterns - Update plan-template.md with Biome and reusability checklist items - Update quality gates to include existing solutions evaluation MINOR: New principle added (Prefer Existing Solutions) and tooling updated (Biome) ``` ## Next Steps 1. **Review the constitution updates** with all team members 2. **Install and configure Biome** in the project (replace Prettier/ESLint) 3. **Set up automated tooling** to enforce standards (Biome, coverage tools) 4. **Configure CI/CD pipeline** to validate constitution compliance with Biome 5. **Train team members** on Context7 MCP usage for finding existing solutions 6. **Create guidelines** for evaluating existing solutions vs custom code 7. **Schedule quarterly review** of constitution effectiveness ## Follow-up Actions - [ ] Team review meeting scheduled for v1.1.0 updates - [ ] Biome installed and configured (replace Prettier/ESLint) - [ ] CI/CD pipeline updated with Biome checks - [ ] Context7 MCP integration documented for finding examples - [ ] Team training on evaluating existing solutions completed - [ ] Guidelines created for custom vs existing code decisions - [ ] First quarterly review date set ## Questions or Concerns? If you have questions about any principle or requirement, please: 1. Review the full constitution at `.specify/memory/constitution.md` 2. Check the rationale provided for each principle 3. Raise concerns in the team discussion channel 4. Propose amendments following the governance process
