Implementation Reference

• src/index.ts:1740-1753 (handler)

  Handler implementation for the todoist_get_comment tool. Validates arguments using isCommentIdArgs, fetches the comment using todoistClient.getComment, formats it with formatComment, and returns the result or error.

  if (name === "todoist_get_comment") {
    if (!isCommentIdArgs(args)) {
      return { content: [{ type: "text", text: "Invalid arguments for get_comment" }], isError: true };
    }
    try {
      const comment = await todoistClient.getComment(args.commentId);
      return { 
        content: [{ type: "text", text: `Comment details:\n${formatComment(comment)}` }], 
        isError: false 
      };
    } catch (error: any) {
      return { content: [{ type: "text", text: `Error getting comment: ${error.message}` }], isError: true };
    }
  }

• src/index.ts:616-629 (schema)

  Tool schema definition including name, description, and input schema requiring commentId.

  const GET_COMMENT_TOOL: Tool = {
    name: "todoist_get_comment",
    description: "Get a specific comment by its ID",
    inputSchema: {
      type: "object",
      properties: {
        commentId: {
          type: "string",
          description: "The ID of the comment to retrieve"

• src/index.ts:1039-1048 (helper)

  Type guard helper function used to validate input arguments for the todoist_get_comment tool.

  function isCommentIdArgs(args: unknown): args is {
    commentId: string;
  } {
    return (
      typeof args === "object" &&
      args !== null &&
      "commentId" in args &&
      typeof (args as { commentId: string }).commentId === "string"
    );
  }

• src/index.ts:732-742 (helper)

  Helper function to format comment details for output in the tool response.

  function formatComment(comment: any): string {
    let commentDetails = `- ID: ${comment.id}\n  Content: ${comment.content}`;
    if (comment.postedAt) commentDetails += `\n  Posted At: ${comment.postedAt}`;
    if (comment.taskId) commentDetails += `\n  Task ID: ${comment.taskId}`;
    if (comment.projectId) commentDetails += `\n  Project ID: ${comment.projectId}`;
    if (comment.attachment) {
      commentDetails += `\n  Attachment: ${comment.attachment.fileName || 'File'} (${comment.attachment.fileType})`;
      if (comment.attachment.fileUrl) commentDetails += `\n  File URL: ${comment.attachment.fileUrl}`;
    }
    return commentDetails;
  }
