What's Wrong?

/ultrareview crashed and returned "Review crashed before producing findings. See session logs for details." This consumed one of my 3 free ultrareview uses without producing any results. The diff scope was ~210 files / ~65k insertions.

What Should Happen?

The ultrareview should either complete successfully or not count against the free usage quota if it crashes on the infrastructure side.

extent analysis

TL;DR

The ultrareview crash may be related to the large diff scope, and adjusting the scope or checking session logs could provide more insight.

Guidance

  • Verify the session logs for more detailed error information to understand the cause of the crash.
  • Consider reducing the diff scope (~210 files / ~65k insertions) to a smaller size to see if the ultrareview completes successfully.
  • Check if there are any known issues or limitations with the Opus Claude Model or the Anthropic API that could be contributing to the crash.
  • Review the usage quota policy to understand under what conditions a crashed ultrareview should not count against the free usage quota.

Notes

The provided information does not include specific details about the session logs or the exact configuration used for the ultrareview, which could be crucial for diagnosing the issue.

Recommendation

Apply workaround: Adjust the diff scope to a smaller size to test if the ultrareview can complete successfully, as the current scope might be causing the crash due to its large size.
