Implementation Reference

• src/cv_resume_builder_mcp/server.py:529-579 (handler)

  The main handler function that implements the 'get_commit_details' tool logic. It resolves the repository path, executes 'git show --stat --format=fuller' to retrieve commit details including stats and diff, limits the output lines if necessary, and returns the result as TextContent.

  async def get_commit_details(commit_hash: Optional[str], repo_name: str, max_lines: int) -> list[TextContent]:
      """Get detailed commit information including code changes (diff)."""
