What's Wrong?

Ran /ultrareview 63 and /ultrareview 64 on two separate PRs. Both times the review launched successfully but
crashed with {"error": "Review crashed unexpectedly. See session logs for details."} — no findings produced.
Session IDs:

• session_01Se2jYrebBcXA8fvs8CMpsq (PR #63, Sophios-Analytics/mur-solutions)
• session_01SJFPLBBACc8y1daqTLxQzV (PR #64, same repo)

Both free credits were consumed. Requesting refund of 2 credits.

What Should Happen?

The ultrareview should have returned a full code review with findings like:

• Security issues (auth bypasses, injection risks, exposed secrets)
• Correctness bugs (race conditions, edge cases, logic errors)
• Performance problems (N+1 queries, missing indexes)
• TypeScript/Next.js specific issues
• A final verdict: READY TO MERGE / MERGE WITH CAUTION / DO NOT MERGE

Instead both sessions launched, ran for ~5-10 min, then returned {"error": "Review crashed unexpectedly."} with
no findings — consuming 2 free credits without delivering any value.

Error Messages/Logs

Steps to Reproduce

1. Open Claude Code in a git repo with a GitHub remote
2. Run /ultrareview <PR_number> where the PR is on a different GitHub org than the one configured in origin

remote (in this case, origin = Patymoore/mur-solutions, PR = Sophios-Analytics/mur-solutions#64)

1. Confirm the launch prompt
2. Wait ~5-10 min
3. Receive {"error": "Review crashed unexpectedly. See session logs for details."} — no findings

Hypothesis: The crash may be caused by the mismatch between the origin remote org and the actual PR org.
Ultrareview resolves Patymoore/mur-solutions#64 but the PR lives in Sophios-Analytics/mur-solutions#64 — the
repo access check passes but the review agent crashes when it tries to fetch the actual diff.
