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.

When to invoke

1. Two or more viable paths to choose between → Round-Table.
2. High-stakes decision (architecture, launch copy, anything with real rollback cost) → Boardroom Debate.
3. Stuck on the same problem after 2+ attempts, or a non-trivial proposal awaiting approval → Devil's Advocate.
