Supports query parameters: ?period=7d|30d|90d|1y|all, ?environment=production|staging|development|all, ?includeFailures=true|false, ?includeMetrics=true|false, ?format=summary|detailed', mimeType: 'application/json', }, { uri: 'adr://code_quality', name: 'Code Quality', description: 'Comprehensive code quality assessment with metrics, issues, and recommendations. Supports query parameters: ?scope=full|changes|critical, ?includeMetrics=true|false, ?includeRecommendations=true|false, ?threshold=0-100, ?format=summary|detailed', mimeType: 'application/json', }, ``` ### Read Resource Handler (src/index.ts) Added 2 case handlers to ReadResourceRequestSchema handler (lines 7476-7514): ```typescript case 'deployment_history': { const { generateDeploymentHistoryResource } = await import('./resources/deployment-history-resource.js'); const result = await generateDeploymentHistoryResource(undefined, url.searchParams); return { contents: [ { uri, mimeType: result.contentType, text: JSON.stringify(result.data, null, 2), }, ], _meta: { lastModified: result.lastModified, etag: result.etag, cacheKey: result.cacheKey, }, }; } case 'code_quality': { const { generateCodeQualityResource } = await import('./resources/code-quality-resource.js'); const result = await generateCodeQualityResource(undefined, url.searchParams); return { contents: [ { uri, mimeType: result.contentType, text: JSON.stringify(result.data, null, 2), }, ], _meta: { lastModified: result.lastModified, etag: result.etag, cacheKey: result.cacheKey, }, }; } ``` **Both handlers include**: - ✅ SearchParams passing for query parameter support - ✅ Metadata inclusion (lastModified, etag, cacheKey) - ✅ Consistent response structure --- ## Technical Implementation ### Architecture Patterns Both resources follow established patterns: 1. **Bridge Pattern**: Leverage deployment-readiness-tool capabilities 2. **Query Parameter Support**: Full URI-based configuration 3. **Caching Strategy**: 5-minute TTL with granular cache keys 4. **Graceful Fallback**: Basic analysis when tool unavailable 5. **Data Extraction**: Parse tool text output into structured JSON 6. **Metadata Tracking**: Confidence scoring and data source attribution ### Code Quality **TypeScript Compilation**: ✅ PASSED ```bash npm run typecheck # Result: No errors ``` **Build Process**: ✅ PASSED ```bash npm run build # Result: Success # Output: dist/src/resources/deployment-history-resource.js # dist/src/resources/code-quality-resource.js ``` **Linting**: ✅ CLEAN - Fixed unused parameter warnings (prefixed with `_`) - Proper error handling - Type-safe implementations - Comprehensive documentation --- ## Resource Count Progression ### Phase Timeline | Phase | Resources Added | Total | % Complete | |-------|----------------|-------|-----------| | **Phase 1** (Foundation) | 7 | 7 | 35% | | **Phase 2** (Templated) | 4 | 11 | 55% | | **Phase 3** (Advanced) | 6 | 17 | 85% | | **Phase 4** (Final) | 3 | **20** | **100%** ✅ | **Note**: Phase 4 actually added 3 resources: - Resource 18: `rule_generation` (bridge, P1 priority) - Resource 19: `deployment_history` (new) - Resource 20: `code_quality` (new) ### Complete Resource Inventory (20 resources) #### Static Resources (14) 1. ✅ architectural_knowledge_graph 2. ✅ analysis_report 3. ✅ adr_list 4. ✅ todo_list 5. ✅ research_index 6. ✅ rule_catalog 7. ✅ project_status 8. ✅ deployment_status (P0 bridge) 9. ✅ environment_analysis (bridge) 10. ✅ memory_snapshots (P1 bridge) 11. ✅ project_metrics 12. ✅ rule_generation (P2 bridge) 13. ✅ deployment_history (NEW) 14. ✅ code_quality (NEW) #### Templated Resources (6) 15. ✅ adr/{id} 16. ✅ research/{topic} 17. ✅ todo/{task_id} 18. ✅ rule/{rule_id} 19. ✅ technology/{name} 20. ✅ pattern/{name} --- ## Bridge Pattern Summary ### Completed Bridges (4) 1. **deployment-status** (P0 - 6.4x gap) ✅ - Tool: deployment-readiness-tool (2,306 lines) - Resource: 804 lines - Operations: 6 (check_readiness, validate_production, test_validation, deployment_history, full_audit, emergency_override) 2. **environment-analysis** (1.9x gap) ✅ - Tool: environment-analysis-tool (1,362 lines) - Resource: 725 lines - Operations: 4 (specs, containerization, requirements, compliance) 3. **memory-snapshots** (P1 - 2.2x gap) ✅ - Tool: memory-loading-tool (602 lines) - Resource: 892 lines - Operations: 6 (current, query, entity, related, intelligence, load-adrs) 4. **rule-generation** (P2 - 3.6x gap) ✅ - Tool: rule-generation-tool (1,183 lines) - Resource: 427 lines - Operations: 3 (generate, validate, create_set) **Total Bridge Coverage**: 100% of identified gaps closed --- ## File Statistics ### New Files Created (2 files, 750 lines) 1. `src/resources/deployment-history-resource.ts` - 305 lines 2. `src/resources/code-quality-resource.ts` - 445 lines ### Modified Files (1 file, ~50 lines) 1. `src/index.ts` - 2 resource entries + 2 case handlers **Total Changes**: ~800 lines of production code --- ## Testing Recommendations ### Unit Tests Needed #### deployment-history-resource.test.ts - Data extraction from tool output - Period parsing (7d, 30d, 90d, 1y, all) - Environment filtering - Failure analysis calculations - DORA metrics computation - Fallback behavior #### code-quality-resource.test.ts - Quality score calculation - Grade assignment (A-F) - Production vs mock code detection - Quality gate validation - Issue categorization - Recommendation prioritization - Fallback file counting ### Integration Tests Needed 1.
