What's Wrong?

/ultrareview <PR# 228> crashed mid-run after charging the account ~$20.
The review never completed; no findings were returned.

## Environment

• Claude Code version: [2.1.132 (Claude Code)]
• OS: macOS [26.2
• Shell: zsh
• Repo: private GitHub repo, monolith with FastAPI backend + Expo React Native mobile

## When

• Crash occurred: [UTC time 14:04]

## Command

/ultrareview 228

PR #228 — backend feature work (one Alembic migration, one FastAPI router refactor,
one new model, one new service module, ~5 new tests, no mobile changes).

## What happened

• Invoked /ultrareview 228 from an interactive Claude Code session.
• The cloud review run started; cost meter ticked to ~$20.
• Run terminated abnormally before any findings were returned to the session.
• Failure mode: [hang / stack trace / silent exit / partial output then stop —

pick the one that matches; paste the last 10–20 lines of output if any]

## Asks

1. Refund of the failed-run charge.
2. Diagnose the crash cause — happy to share PR diff or transcript if useful.

## Additional context

• This is the first /ultrareview invocation against this branch.
• The PR's local /review pass completed normally and returned 2 Bucket-A nits

(already auto-fixed) — so the failure is specific to /ultrareview, not
upstream tooling.

• Local test suite: 732/732 green. The PR is currently ready to merge but

blocked pending review of a sensitive surface (existing webhook dispatch
refactor + Alembic migration), which is why ultrareview was invoked.

What Should Happen?

## Expected

A completed multi-agent review with findings (or a clean pass) returned to the
session, billed against successful completion.

## Actual

No findings, no completion, $20 charged.
