What's Wrong?

/ultrareview was launched against branch v2.1.0 → main and announced "Free ultrareview 1 of 3". The job ran, was marked completed, but returned no findings — only an error message saying it crashed before producing any. Despite the server-side crash, the free credit was consumed (now showing 1 of 3 used).

Scope at launch (per command output): 211 files changed, 16,400 insertions, 1,361 deletions.

Requesting refund of the consumed free credit — server-side crashes that produce no output should not count against the free quota.

What Should Happen?

Either:
(a) The ultrareview run completes and produces findings, OR
(b) If the run crashes server-side before producing any findings, the free credit is not consumed (it should remain at 3 of 3 free reviews available).

Currently the credit is consumed regardless of outcome, which means a crashed run silently costs the user one of their three free credits with zero value delivered.

Error Messages/Logs

{"error":"Review crashed before producing findings. See session logs for details."}

Steps to Reproduce

1. On a feature branch with a large diff vs main (in my case: 211 files, ~16k insertions, ~1.3k deletions).
2. Run /ultrareview (no argument — uses current branch vs main).
3. Command announces "Free ultrareview 1 of 3" and returns a tracking URL.
4. Wait for the cloud job to finish (~5-10 min expected).
5. Job is marked completed but returns:

{"error":"Review crashed before producing findings. See session logs for details."}

1. Free credit count is now 1 of 3 used, with no review produced.

Additional Information

• Tracking session URL: https://claude.ai/code/session_01FeMucJY998BPVQLv76x8YW
• This was the first use of the free ultrareview quota for this account, so I cannot confirm whether the feature ever worked before.
• The branch had a large diff (~16k insertions) — the crash may correlate with scope size, but the command accepted the launch without warning.

• Refund request: please return the consumed credit (currently 1/3 used → should be 0/3 since no findings were produced).
