What's Wrong?

Two consecutive /ultrareview runs against the same PR crashed server-side before producing any findings, yet both were counted against my free quota (2 of 3 used). I'm now reluctant to retry with my last remaining credit.

Target PR: tlrktz/fids-review-2#1

Affected sessions:

• session_01Mx5fMyYWY5u4b5hrBHWCpF
• session_01XwsyDgEA8NTfMaN3WsbaPQ

Output returned in both cases:
{"error":"Review crashed before producing findings. See session logs for details."}

Expected behavior:

• The review completes and returns findings, OR
• If the review crashes before producing findings, the run should not be counted against the free quota.

Requests:

1. Refund the 2 consumed credits, since neither run produced output.
2. Investigate the crash via the session logs above.
3. Consider making quota consumption contingent on a successful findings response.

Environment:

• Claude Code CLI
• Platform: darwin (macOS)
• Repo: git, branch initial

What Should Happen?

• The review completes and returns findings, OR
• If the review crashes before producing findings, the run should not be counted against the free quota.

❯ Now it's using my limited Ultrareview credits. I'm scared to run it again because I only have 3, and it's telling me I've used them up. This sucks.                                                                                           
                                                                                                                           
⏺ That's frustrating — both runs crashed server-side before producing findings, which shouldn't count against your quota. I'd recommend reporting this at https://github.com/anthropics/claude-code/issues with the two session IDs (session_01Mx5fMyYWY5u4b5hrBHWCpF and session_01XwsyDgEA8NTfMaN3WsbaPQ) so the team can refund the credits and investigate the crash.

Steps to Reproduce

1. Start Claude Code
2. Run /ultrareview
3. "API Error: Server is temporarily limiting requests (not your usage limit) · Rate limited"
4. Ultrareview credit is decremented without having received anything for it
