Implementation Reference

• handlers/drive.ts:85-98 (handler)

  The handler function that executes the logic for the 'google_drive_delete_file' tool. It validates the input arguments using isDeleteFileArgs and calls the GoogleDrive instance's deleteFile method.

  export async function handleDriveDeleteFile(
    args: any,
    googleDriveInstance: GoogleDrive
  ) {
    if (!isDeleteFileArgs(args)) {
      throw new Error("Invalid arguments for google_drive_delete_file");
    }
    const { fileId, permanently } = args;
    const result = await googleDriveInstance.deleteFile(fileId, permanently);
    return {
      content: [{ type: "text", text: result }],
      isError: false,
    };
  }

• tools/drive/index.ts:98-116 (schema)

  The Tool object definition for 'google_drive_delete_file', including the input schema for validation.

  export const DELETE_FILE_TOOL: Tool = {
    name: "google_drive_delete_file",
    description: "Delete a file from Google Drive",
    inputSchema: {
      type: "object",
      properties: {
        fileId: {
          type: "string",
          description: "ID of the file to delete",
        },
        permanently: {
          type: "boolean",
          description:
            "Whether to permanently delete the file or move it to trash",
        },
      },
      required: ["fileId"],
    },
  };

• server-setup.ts:201-205 (registration)

  Switch case in the tool call handler that registers and routes 'google_drive_delete_file' calls to the appropriate handler function.

  case "google_drive_delete_file":
    return await driveHandlers.handleDriveDeleteFile(
      args,
      googleDriveInstance
    );

• utils/helper.ts:287-296 (helper)

  Type guard function used in the handler to validate arguments for 'google_drive_delete_file'.

  export function isDeleteFileArgs(args: any): args is {
    fileId: string;
    permanently?: boolean;
  } {
    return (
      args &&
      typeof args.fileId === "string" &&
      (args.permanently === undefined || typeof args.permanently === "boolean")
    );
  }
