commit-rewriter 0.1

  • Simon Willison released commit-rewriter 0.1, a new Python web app designed to help users easily edit and clean up their Git commit messages.
  • The tool was developed to address the specific problem of “coding agent cruft” and references to private issue IDs found in commit messages, making them unsuitable for public release, as experienced with Datasette security releases.
  • To use it, run uvx commit-rewriter path/to/repo; the app includes a practical safety feature by creating a timestamped branch of the current repository state before rewriting commits, allowing for easy reversion if needed.
