Codereview of Current Diff (Meta-Skill)

A combinator-style meta-skill that runs three independent reviewers in parallel over the currently-uncommitted diff, then arbitrates a single verdict with a strict priority rule.

This is the same combinator + arbitrate pattern as meta-security-review-bundle, applied to a code-review domain. The three reviewers each carry a tight, project-specific rubric — safety focuses on injection / credentials / G1.6 contract; tests focuses on the "new public surface ⇒ corresponding test" expectation; style flags only a fixed list of antipatterns so it doesn't drift into free-form opinions.

Trigger surface

Fire by saying multi-reviewer diff, codereview my diff, or one of the localized triggers listed in the frontmatter. The diff is read from the working tree (git diff --cached HEAD, falling back to git diff HEAD if nothing is staged).

Fallback

If read_diff returns NO_DIFF, the downstream reviewers should reply with their respective clean verdicts ("CLEAR" / "PASS" / "CLEAN") and arbitrate emits PASS_WITH_NOTES: clean. If a reviewer LLM step fails, the orchestrator's partial outputs are visible in step_outputs; operator should manually re-run the failed reviewer.
