Claude for Codex (CLI + cloud)

Cross-vendor diff review in the Codex (CLI + cloud) stack. Cloud PRs especially want a second model reading the diff. Claude is a different lineage than Codex, so it catches things Codex's self-review wouldn't (different priors on idiomatic code, different blind spots). Paste the PR diff + the ticket, ask for a structured review.

Cross-vendor review with Claude

Paste the PR diff + the original ticket into Claude. Ask for a structured review (coverage, edge cases, regressions, naming, idiomatic-code drift). For Cloud PRs especially, this catches drift the autonomous lane introduced. A different model lineage notices things the same vendor's self-review wouldn't.

Prompt · Cross-vendor PR review

Review the PR below as a skeptical senior engineer who didn't write it.

Original ticket:
"""
{{paste ticket}}
"""

Diff:
"""
{{paste git diff}}
"""

Output:
1. Does the diff actually solve the ticket? Anything missing?
2. Edge cases or failure modes the implementation doesn't handle (pick the 3 most likely).
3. Naming / idiomatic-code drift. Flag anything that looks like cross-vendor pattern leakage.
4. Specific lines I should re-read.
5. Verdict: ship / fix list / scrap and re-prompt.

Be specific (line refs, not vibes). Don't pad.
