update-task-text

Instructions

Implementation Reference

• src/tools/task-tools.ts:349-379 (handler)

  The handler function that implements the core logic of the 'update-task-text' tool by calling the Sunsama client to update the task's text and returning a formatted JSON response.

  export const updateTaskTextTool = withTransportClient({
    name: "update-task-text",
    description: "Update the text/title of a task",
    parameters: updateTaskTextSchema,
    execute: async (
      { taskId, text, recommendedStreamId, limitResponsePayload }:
        UpdateTaskTextInput,
      context: ToolContext,
    ) => {
      const options: {
        recommendedStreamId?: string | null;
        limitResponsePayload?: boolean;
      } = {};
      if (recommendedStreamId !== undefined) {
        options.recommendedStreamId = recommendedStreamId;
      }
      if (limitResponsePayload !== undefined) {
        options.limitResponsePayload = limitResponsePayload;
      }
  
      const result = await context.client.updateTaskText(taskId, text, options);
  
      return formatJsonResponse({
        success: result.success,
        taskId,
        text,
        textUpdated: true,
        updatedFields: result.updatedFields,
      });
    },
  });

• src/schemas.ts:247-260 (schema)

  Zod schema that validates and describes the input parameters for the 'update-task-text' tool.

  export const updateTaskTextSchema = z.object({
    taskId: z.string().min(1, "Task ID is required").describe(
      "The ID of the task to update",
    ),
    text: z.string().min(1, "Task text is required").describe(
      "The new text/title for the task",
    ),
    recommendedStreamId: z.string().nullable().optional().describe(
      "Recommended stream ID (optional)",
    ),
    limitResponsePayload: z.boolean().optional().describe(
      "Whether to limit the response payload size",
    ),
  });

• src/main.ts:32-44 (registration)

  The registration code in the MCP server setup that registers all tools, including 'update-task-text', by iterating over the allTools array.

  // Register all tools
  allTools.forEach((tool) => {
    server.registerTool(
      tool.name,
      {
        description: tool.description,
        inputSchema: "shape" in tool.parameters
          ? tool.parameters.shape
          : tool.parameters,
      },
      tool.execute,
    );
  });

• src/tools/task-tools.ts:406-426 (registration)

  The taskTools array where 'updateTaskTextTool' is included and exported for further aggregation into allTools and registration.

  export const taskTools = [
    // Query tools
    getTasksBacklogTool,
    getTasksByDayTool,
    getArchivedTasksTool,
    getTaskByIdTool,
  
    // Lifecycle tools
    createTaskTool,
    deleteTaskTool,
  
    // Update tools
    updateTaskCompleteTool,
    updateTaskSnoozeDateTool,
    updateTaskBacklogTool,
    updateTaskPlannedTimeTool,
    updateTaskNotesTool,
    updateTaskDueDateTool,
    updateTaskTextTool,
    updateTaskStreamTool,
  ];

• src/tools/shared.ts:29-65 (helper)

  The withTransportClient higher-order function used to wrap the raw tool config, providing transport-aware client resolution and MCP-compliant response formatting.

  export function withTransportClient(toolConfig: ToolConfig) {
    return {
      name: toolConfig.name,
      description: toolConfig.description,
      parameters: toolConfig.parameters,
      execute: async (args: any, extra: any = {}) => {
        try {
          // Auto-resolve client based on transport
          const client = await getClient(extra.session);
  
          // Execute tool with injected client
          const context: ToolContext = { ...extra, client };
          const result = await toolConfig.execute(args, context);
  
          // Ensure MCP-compliant response format
          if (result && Array.isArray(result.content)) {
            return result;
          }
  
          // Wrap if needed
          return {
            content: [
              {
                type: "text",
                text: typeof result === "string"
                  ? result
                  : JSON.stringify(result, null, 2)
              }
            ]
          };
        } catch (error) {
          console.error(`Tool ${toolConfig.name} error:`, error);
          throw error;
        }
      }
    };
  }
