Live app evidence for agents

See what React did. Find the cause. Check the result.

Pair Genie with agent-browser or agent-device. The agent drives the UI, reads the live React and TanStack state, then checks the change against live evidence.

Test hard-to-reach states

Read props, hooks, and Context. Force rare states, verify the UI, and save screenshots.

Trace the observed cause

Join one action to its hook change, render, effect, source, and coverage.

Check the result

Compare repeated runs and let the UI driver confirm behavior still works.
