Adding New Prompts

Choose the right category:
- profiles/ - AI assistant personalities
- skills/ - Development techniques
- onboarding/ - Setup and integration
Follow the schema (see public/schema/prompt-schema.json):
{ "id": "unique-prompt-id", "title": "Human-readable title", "description": "What this prompt does", "category": "profiles|skills|onboarding", "tags": ["relevant", "searchable", "tags"], "prompt": "Your detailed prompt text here...", "examples": [ { "input": "Example input", "output": "Expected output description" } ], "effectiveness": 4.5, "author": "Your Name", "version": "1.0.0", "created_at": "2024-01-01T00:00:00Z", "updated_at": "2024-01-01T00:00:00Z" }

Submit a pull request with clear description

Adding New Tools

Tools extend the MCP server functionality with custom operations. Follow these steps:

Choose a meaningful tool name (e.g., analyze_code, generate_tests, check_dependencies)
Create the tool definition in public/tools/your-tool.json:
{ "id": "analyze_code_complexity", "name": "analyze_code_complexity", "description": "Analyze code complexity and suggest improvements", "input_schema": { "type": "object", "properties": { "code": { "type": "string", "description": "The code to analyze" }, "language": { "type": "string", "description": "Programming language (js, ts, py, etc.)" }, "metrics": { "type": "array", "items": { "type": "string" }, "description": "Metrics to calculate (cyclomatic, cognitive, etc.)" } }, "required": ["code", "language"] } }
Implement the tool logic in src/server.ts CallToolRequestSchema handler:
case "analyze_code_complexity": if (!args || typeof args.code !== "string") { throw new McpError(ErrorCode.InvalidRequest, "Code parameter is required"); } const analysis = await this.analyzeCodeComplexity(args.code, args.language); return { content: [ { type: "text", text: JSON.stringify(analysis, null, 2) } ] };
Test the tool with MCP Inspector and various inputs

Tool Ideas:

validate_env_vars: Check environment variable completeness
generate_tests: Create unit tests for given code
check_dependencies: Analyze package.json for vulnerabilities
format_sql: Format and validate SQL queries
analyze_performance: Detect performance bottlenecks
generate_docs: Create documentation from code comments
