Implementation Reference

• src/tools/codegen/index.ts:160-180 (handler)

  The core handler function for the 'get_codegen_session' tool. It retrieves the code generation session by ID from the ActionRecorder instance and returns it, or throws an error if not found.

  export const getCodegenSession: Tool = {
    name: 'get_codegen_session',
    description: 'Get information about a code generation session',
    parameters: {
      type: 'object',
      properties: {
        sessionId: {
          type: 'string',
          description: 'ID of the session to retrieve'
        }
      },
      required: ['sessionId']
    },
    handler: async ({ sessionId }: { sessionId: string }) => {
      const session = ActionRecorder.getInstance().getSession(sessionId);
      if (!session) {
        throw new Error(`Session ${sessionId} not found`);
      }
      return session;
    }
  };

• src/toolHandler.ts:369-370 (registration)

  The dispatch registration in the main tool handler switch statement that calls the getCodegenSession.handler with input arguments.

  case 'get_codegen_session':
    return await handleCodegenResult(getCodegenSession.handler(args));

• src/tools.ts:50-63 (schema)

  MCP tool definition including the input schema for 'get_codegen_session' used in createToolDefinitions().

  {
    name: "get_codegen_session",
    description: "Get information about a code generation session",
    inputSchema: {
      type: "object",
      properties: {
        sessionId: { 
          type: "string", 
          description: "ID of the session to retrieve" 
        }
      },
      required: ["sessionId"]
    }
  },

• src/tools/codegen/index.ts:204-209 (registration)

  Includes getCodegenSession in the exported codegenTools array.

  export const codegenTools = [
    startCodegenSession,
    endCodegenSession,
    getCodegenSession,
    clearCodegenSession
  ]; 

• src/tools.ts:488-488 (registration)

  Lists 'get_codegen_session' in the CODEGEN_TOOLS constant array.
