Implementation Reference

• src/tools/codegen/index.ts:175-195 (handler)

  The Tool object defining the get_codegen_session tool, including its handler function that fetches the session from ActionRecorder by ID and returns it or throws 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 }, _context?: { server?: any }) => {
      const session = ActionRecorder.getInstance().getSession(sessionId);
      if (!session) {
        throw new Error(`Session ${sessionId} not found`);
      }
      return session;
    },
  };

• src/tools.ts:50-63 (schema)

  The input schema definition for the get_codegen_session tool used in tool discovery/registration.

  {
    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/toolHandler.ts:436-437 (registration)

  The dispatch/registration case in the main tool handler that calls the getCodegenSession.handler when the tool is invoked.

  case "get_codegen_session":
    return await handleCodegenResult(getCodegenSession.handler(args, { server }));

• src/toolHandler.ts:37-40 (registration)

  Import of the getCodegenSession tool from codegen/index.ts into the main toolHandler.

  clearCodegenSession,
  endCodegenSession,
  getCodegenSession,
  startCodegenSession,

• src/tools.ts:531-531 (registration)

  Listing of get_codegen_session in the CODEGEN_TOOLS array for tool categorization.

  "get_codegen_session",
