mcp-backlog-md/src/tools/demoteTask.ts

An MCP (Model Context Protocol) server for the backlog.md CLI tool.

/**
 * demoteTask.ts
 *
 * Purpose:
 * - Provides the functionality to demote a task to a draft in the backlog.
 * - Exposes this functionality as an MCP tool.
 *
 * Logic Overview:
 * - Defines a Zod schema for input validation.
 * - The `execute` function constructs a `backlog task demote` command.
 * - The command is passed to the centralized `executeCommand` function.
 *
 * Last Updated:
 * 2025-07-21 by Cline (Refactored to use centralized command executor)
