Show HN: Crit – local review tool for agent plans and code diffs

Crit is a single-binary CLI that opens your file or code diffs in a browser with GitHub-inspired interface. Your favourite agent acts on the feedback and responds back - continue until you're happy.

I've been building this for a few months now and it's been helping me a lot juggling parallel conversations with agents, making it easier to actually review the plans they generate and the resulting code - all before it hits GitHub.

It also allows you to export the plans to a hosted service (which you can self-host for privacy), to solicit feedback from your team. No account needed, and reviews are automatically deleted after 30 days of inactivity.
