## FAQ

### What can the assistant see in the console?

The assistant can access logs, warnings, and uncaught exceptions, including the file name, 1-based line number, and stack trace.

### How does it handle source maps?

It can resolve source maps to recover original pre-bundling files, including external .map files located behind authentication, and supports full-text search across them.

### Can I interact with the web app while the assistant is using it?

Yes, you can take over at any time; your clicks, choices, and typing are recorded and readable by the assistant.

### What happens if a script enters an infinite loop?

The server enforces timeouts on calls into the page; if a page is wedged in an infinite loop, DevCDP will abort the runaway script and retry automatically.
