Two-Pass Review

A reusable review protocol that produces high-confidence findings on code changes by running a code-reviewer pass followed by an adversarial verifier pass. All output conforms to the Output Schema below.

When to use

For code review where you'd present findings to the user and a false positive costs real time (final review at end of plan-runner, pre-merge audit). Don't present unverified findings for non-trivial code reviews — always run both passes.

For non-code artifacts (PRDs, plans, prose), spawn reviewer directly — this skill is hard-wired to code-reviewer for Pass 1.

Protocol

Pass 1 — Review

Spawn the code-reviewer agent with:

• Artifact: the file(s) or diff to review
• Criteria: what to review against
• Scope: what's in-bounds
• Output contract: "Return a ReviewOutput envelope (see Output Schema). Set verdict and evidence to null on all findings. Populate checks_run with what you evaluated (e.g., criteria names, file paths checked)."
