Second Opinion — cross-check before you commit

Stress-test your own answer with reviewers who don't share your framing. The reviewer set depends on what you have available:

• Always available: the isolated idea-validator agent (same model family, but NO parent context — it can't anchor on your framing, and it READS the actual files).
• If you have access to a second model family (Gemini, GPT, …, via a CLI wrapper or API): add it as an external reviewer. A different training distribution catches different blind spots. It reviews from the brief only (no repo access) — lean on it for concept and tech-currency, not file-level facts.

Already have your own review setup? If your user-level configuration defines a review board or a second-opinion skill (your own reviewer agent, a model list, a wrapper for another model family), use that one and skip this skill — two review procedures for one decision drift apart. This skill is the default for people who have none.
