Run a Fleet of Cloud Bug-Hunters Before Every Merge with /code-review ultra

TL;DR: /code-review ultra runs a fleet of cloud agents that independently verify every finding before reporting it — higher signal than a local review, runs in the background while you keep working.

Every local code review is bounded by one model's context and your patience. /code-review ultra (alias /ultrareview) ships your diff to a remote cloud sandbox, spins up a fleet of bug-finding agents, has each finding independently verified by a second agent, and delivers only confirmed bugs to your terminal — typically in 5–10 minutes, while you keep coding.

Run it now

Review your current branch against the default branch:

/code-review ultra

Review a specific GitHub PR:

/code-review ultra 1234

Claude Code shows a confirmation dialog with scope (file and line count), your remaining free runs, and estimated cost before anything launches. The review runs as a background task — use /tasks to watch progress.

Use it from CI (the killer workflow)

claude ultrareview runs headlessly, blocks until the remote review finishes, and exits 0 on success or 1 on failure:

# In a GitHub Actions step or pre-merge gate:
claude ultrareview --json > review.json
cat review.json | jq '.bugs[] | .file + ": " + .description'

Key flags:

• --json — outputs the raw bugs.json payload instead of the formatted report
• --timeout 20 — cap wait time in minutes (default 30)
• Progress goes to stderr; findings go to stdout — CI-safe by design

Pricing

Plan	Included	After
Pro / Max	3 free runs (one-time)	~$5–$20 per review as usage credits
Team / Enterprise	None	~$5–$20 per review as usage credits

Cost scales with diff size. A run stopped early or that errors still consumes a free run; paid runs bill only for the portion that ran.

Which review command for which situation?

Command	Where it runs	When to use
/code-review	Local session	Fast feedback while iterating
/review <pr>	Local session	Look over a teammate's PR
/code-review ultra	Remote cloud sandbox	Pre-merge confidence on auth, migrations, payments

Use ultrareview before merging anything where a missed bug has high blast radius. Not available on Bedrock, Vertex, or Foundry; requires a Claude.ai account (run /login if you're on API key only).
