PackRehearsal

Local CLI that checks npm/Python/Rust package manifests against the archive before release.

Desktopfreeglobal

PackRehearsal is a local command-line tool that checks whether an npm, Python, or Rust package's manifest actually matches the archive bytes about to be published, catching missing files, mismatched metadata, or accidental credential leaks before release. Its default scan makes no network calls and never executes the project's own code. It can also turn new findings into a bounded task for the Codex coding agent to fix. Built for package maintainers and release engineers.
