Description

Summary

Command Code (ran via bunx command-code raises "ERROR Cannot read properties of null (reading 'useState')" mid-session all the time. Whether it's reasoning, calling tools or anything else.

Expected Behavior

The session should go on properly.

Actual Behavior

Stack trace:

Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://react.dev/link/invalid-hook-call for tips about how to debug and fix this problem.
