About Mirrors

Mirrors rebuilds the systems your AI agents call and replays real sessions against every prompt, tool, or model change before it reaches production. Schema, seed data, and tool behavior mined into a runnable copy of the systems your agent calls, including the internal tools nobody will give you a test instance of. Every change is tested against past sessions before it merges. The Replay screen diffs each recorded production call against its counterpart in the environment, so you can see where the two agree and where they drift before you trust it with a merge gate.
