  The core logic that updates the todo status to 'completed' in the database.

  async def complete_todo(todo_id: int) -> str:
      """Mark a todo as complete.
  
      Args:
          todo_id: The ID of the todo to complete
  
      Returns:
          Success message or error
      """
      db = await get_db()
  
      # Get todo title for confirmation
      cursor = await db.execute("SELECT title FROM todos WHERE id = ?", (todo_id,))
      row = await cursor.fetchone()
  
      if not row:
          return f"Error: Todo #{todo_id} not found."
  
      # Mark as complete
      await db.execute(
          "UPDATE todos SET status = 'completed', completed_at = CURRENT_TIMESTAMP WHERE id = ?",
          (todo_id,),
      )
      await db.commit()
  
      return f"✓ Completed: {row['title']}"

• src/coach_ai/server.py:146-153 (registration)

  The MCP tool registration using @mcp.tool() and the wrapper function that calls the storage handler.

  async def complete_todo(todo_id: int) -> str:
      """Mark a todo as complete.
  
      Args:
          todo_id: The ID of the todo to complete
      """
      return await storage.complete_todo(todo_id)
