commit-rewriter: a uvx web app for stripping agent cruft out of commit messages before a release.

Simon Willison released 0.1 on September 14 specifically to clean up Datasette security-release history containing, in his words, coding agent cruft and references to private-repo issue IDs. uvx commit-rewriter path/to/repo gives you a commit sidebar, an editable message box and formatted diffs, and creates a timestamped branch before rewriting from the first edited message forward. The gap it fills is real: the history an agent generates is rarely the history you want attached to a public tag.
