Entry Point (`index.ts`) + +Initializes the MCP server with three capabilities: +- **Tools**: Callable functions (get_context, validate, search, profiles, health) +- **Resources**: Readable content (profiles, standards) +- **Prompts**: Pre-built prompts (implement, review) + +### 2. Tools Module (`tools.ts`) + +Defines 5 simplified tools following MCP specification: + +| Tool | Purpose | +|------|---------| +| `get_context` | **Primary tool** - Returns complete context for a task | +| `validate` | Validates code against standards | +| `search` | Searches standards documentation | +| `profiles` | Lists available profiles | +| `health` | Server health check | + +### 3. Agent Module (`agent.ts`) + +Handles intelligent task processing: + +```typescript +// Task type classification +classifyTaskType(task: string) → 'feature' | 'bugfix' | 'refactor' | 'test' | ... + +// Project stack auto-detection +detectProjectStack(projectDir: string) → { language, framework, suggestedProfile } + +// Guardrails retrieval +getGuardrails(taskType, projectConfig) → { mandatory, avoid, workflow } +``` + +### 4. Profiles Module (`profiles.ts`) + +Manages profile loading with: +- **Parallel loading**: All YAML files loaded concurrently +- **Caching**: 60-second TTL cache +- **Priority override**: custom/ > root/ > templates/ +- **Validation**: Zod schema validation + +### 5. Guardrails Module (`guardrails.ts`) + +Loads task-specific guardrails from YAML: +- Mandatory rules (MUST do) +- Avoid rules (MUST NOT do) +- Workflow steps (Chain-of-thought guidance) +- Patterns and anti-patterns + +## Data Flow + +### Tool Call Flow + +``` +1. Client calls tool (e.g., get_context) + │ + ▼ +2. handleToolCall() validates input (Zod schema) + │ + ▼ +3. classifyTaskType() determines task type + │ + ▼ +4. detectProjectStack() auto-detects tech stack (if project_dir provided) + │ + ▼ +5. getProfile() loads matching profile from cache/YAML + │ + ▼ +6. getGuardrails() loads task-specific guardrails + │ + ▼ +7. Format and return markdown response +``` + +### Profile Loading Flow + +``` +1. loadProfiles() checks cache + │ + ├── Cache valid? → Return cached profiles + │ + └── Cache expired? + │ + ▼ + 2. Load directories in parallel: + - profiles/templates/ + - profiles/custom/ + - profiles/ (root) + │ + ▼ + 3. For each directory, load all YAML files in parallel + │ + ▼ + 4. Parse YAML → Validate with Zod → Create Profile objects + │ + ▼ + 5. Merge with priority (custom > root > templates) + │ + ▼ + 6. Update cache, return profiles +``` + +## Type System + +### Profile Schema (simplified) + +```typescript +interface Profile { + name: string; + description?: string; + architecture?: { + type: 'hexagonal' | 'clean' | 'layered' | 'feature-based'; + layers?: Layer[]; + enforceLayerDependencies?: boolean; + }; + codeQuality?: { + maxMethodLines: number; + maxClassLines: number; + minimumTestCoverage: number; + }; + naming?: { + general: Record; + suffixes: Record; + }; + testing?: TestingConfig; + ddd?: DDDConfig; + cqrs?: CQRSConfig; + // ... more sections + codeExamples?: Record; + antiPatterns?: Record; +} +``` + +### Guardrails Schema + +```typescript +interface Guardrails { + taskType: string; + mandatory: string[]; + recommended?: string[]; + avoid: string[]; + workflow?: { + steps: Array<{ + name: string; + description: string; + actions: string[]; + }>; + }; + patterns?: Record; + antiPatterns?: Record; +} +``` + +## Performance Optimizations + +1. **Parallel Loading**: All I/O operations use `Promise.all()` +2. **Caching**: Profiles and standards cached with 60s TTL +3. **Lazy Loading**: Resources loaded only when requested +4. **Schema Validation**: Zod schemas validate at parse time + +## Testing Strategy + +| Test Type | Location | Purpose | +|-----------|----------|---------| +| Unit | `tests/*.test.ts` | Individual function testing | +| Integration | `tests/handlers.test.ts` | Tool handler integration | +| E2E | `tests/mcp-protocol.test.ts` | Full MCP protocol compliance | +| Schema | `tests/profiles.test.ts` | YAML profile validation | + +### Running Tests + +```bash +npm test # Run all tests +npm run test:watch # Watch mode +npm run coverage # Coverage report +``` + +## Extensibility + +### Adding a New Profile + +1.
