• src/tools/codegen/index.ts:185-205 (handler)

  The clearCodegenSession tool object defining the handler function that executes the tool logic by clearing the specified codegen session using ActionRecorder.clearSession().

  export const clearCodegenSession: Tool = {
    name: "clear_codegen_session",
    description: "Clear a code generation session",
    parameters: {
      type: "object",
      properties: {
        sessionId: {
          type: "string",
          description: "ID of the session to clear",
        },
      },
      required: ["sessionId"],
    },
    handler: async ({ sessionId }: { sessionId: string }) => {
      const success = ActionRecorder.getInstance().clearSession(sessionId);
      if (!success) {

      }
      return { success };
    },
  };
