Software Planning Tool

Instructions

Implementation Reference

• src/index.ts:278-297 (handler)

  MCP tool handler for 'remove_todo': validates current goal, extracts todoId from arguments, calls storage.removeTodo, and returns success message.

  case 'remove_todo': {
    if (!this.currentGoal) {
      throw new McpError(
        ErrorCode.InvalidRequest,
        'No active goal. Start a new planning session first.'
      );
    }
  
    const { todoId } = request.params.arguments as { todoId: string };
    await storage.removeTodo(this.currentGoal.id, todoId);
  
    return {
      content: [
        {
          type: 'text',
          text: `Successfully removed todo ${todoId}`,
        },
      ],
    };
  }

• src/index.ts:169-182 (registration)

  Registers the 'remove_todo' tool in the list of available tools, including its description and input schema.

  {
    name: 'remove_todo',
    description: 'Remove a todo item from the current plan',
    inputSchema: {
      type: 'object',
      properties: {
        todoId: {
          type: 'string',
          description: 'ID of the todo item to remove',
        },
      },
      required: ['todoId'],
    },
  },

• src/storage.ts:97-106 (helper)

  Core implementation that removes the specified todo from the plan by filtering the todos array and persisting changes to storage.

  async removeTodo(goalId: string, todoId: string): Promise<void> {
    const plan = await this.getPlan(goalId);
    if (!plan) {
      throw new Error(`No plan found for goal ${goalId}`);
    }
  
    plan.todos = plan.todos.filter((todo: Todo) => todo.id !== todoId);
    plan.updatedAt = new Date().toISOString();
    await this.save();
  }

• src/index.ts:172-181 (schema)

  Defines the input schema for the 'remove_todo' tool: requires a 'todoId' string.

  inputSchema: {
    type: 'object',
    properties: {
      todoId: {
        type: 'string',
        description: 'ID of the todo item to remove',
      },
    },
    required: ['todoId'],
  },
