Implementation Reference

• yellhorn_mcp/server.py:395-413 (handler)

  The main handler function that executes the get_workplan tool logic. It extracts the repository path from the context and calls get_issue_body to retrieve the GitHub issue body content for the specified issue number.

  async def get_workplan(ctx: Context, issue_number: str) -> str:
      """Retrieves the workplan content for a specified issue number.
  
      Args:
          ctx: Server context.
          issue_number: The GitHub issue number to retrieve.
  
      Returns:
          The workplan content as a string.
  
      Raises:
          YellhornMCPError: If retrieval fails.
      """
      try:
          repo_path: Path = ctx.request_context.lifespan_context["repo_path"]
          return await get_issue_body(repo_path, issue_number)
      except Exception as e:
          raise YellhornMCPError(f"Failed to retrieve workplan: {str(e)}")
