Implementation Reference

• src/tasks/tools.ts:162-192 (handler)

  The complete_task tool registration and handler implementation. Validates the task ID using CompleteTaskSchema, retrieves the task from storage, updates its status to 'done', and returns the result as JSON.

  server.addTool({
    name: "complete_task",
    description: "Mark a task as completed.",
    execute: async (params: any) => {
      try {
        // Validate input parameters
        const validatedParams = CompleteTaskSchema.parse(params);
        const task = taskStorage.get(validatedParams.id);
        
        if (!task) {
          return JSON.stringify({
            error: `Task with ID ${validatedParams.id} not found`
          });
        }
        
        // Update task status to done
        const updatedTask = taskStorage.update(validatedParams.id, { 
          status: "done"
        });
        
        return JSON.stringify({
          task: updatedTask,
          message: "Task marked as completed"
        });
      } catch (error) {
        return JSON.stringify({ 
          error: `Invalid complete_task parameters: ${error instanceof Error ? error.message : String(error)}`
        });
      }
    }
  });

• src/tasks/tools.ts:32-35 (schema)

  Zod schema defining the input parameters for the complete_task tool: a required UUID string for the task ID.

  // Schema for complete_task parameters
  const CompleteTaskSchema = z.object({
    id: z.string().uuid()
  });
