Implementation Reference

• src/tools/aiconfigs.ts:34-78 (handler)

  The handler function that implements the core logic of the 'generate_cursor_rules' tool, generating a .cursorrules file content based on project name, languages, frameworks, and databases.

  export function generateCursorRulesHandler(args: any) {
      const { projectName, languages, frameworks = [], databases = [] } = args;
  
      const content = `# ${projectName} - Cursor Rules
  
  ## Project Overview
  This is a ${languages.join("/")} project${frameworks.length ? ` using ${frameworks.join(", ")}` : ""}.
  
  ## Code Style
  - Follow ${languages[0]} best practices and style guides
  - Use consistent naming conventions
  - Write self-documenting code with clear variable names
  - Keep functions small and focused (< 50 lines)
  
  ## Architecture
  - Separate concerns clearly (MVC, Clean Architecture, etc.)
  - Use dependency injection where applicable
  - Keep business logic separate from I/O
  
  ## Testing
  - Write unit tests for all business logic
  - Use integration tests for API endpoints
  - Aim for > 80% code coverage
  
  ## Error Handling
  - Use structured error handling
  - Log errors with appropriate context
  - Return meaningful error messages to users
  
  ## Security
  - Never commit secrets or API keys
  - Validate all user input
  - Use parameterized queries for databases
  ${databases.length ? `\n## Database (${databases.join(", ")})\n- Use connection pooling\n- Handle transactions properly\n- Avoid N+1 queries` : ""}
  
  ## Documentation
  - Document all public APIs
  - Keep README up to date
  - Use inline comments for complex logic only

      return {
          content: [{ type: "text", text: content }]
      };
  }

• src/tools/aiconfigs.ts:3-12 (schema)

  Zod-based input schema definition for the 'generate_cursor_rules' tool, specifying parameters like projectName, languages, frameworks, and databases.

  export const generateCursorRulesSchema = {
      name: "generate_cursor_rules",
      description: "Generates a .cursorrules file for Cursor AI based on the project stack.",
      inputSchema: z.object({
          projectName: z.string().describe("Name of the project"),
          languages: z.array(z.string()).describe("Programming languages used (e.g., ['typescript', 'python'])"),
          frameworks: z.array(z.string()).optional().describe("Frameworks used (e.g., ['react', 'fastapi'])"),
          databases: z.array(z.string()).optional().describe("Databases used (e.g., ['postgresql', 'redis'])")
      })
  };
