Second Opinion

Protocol

1 — Brief the subagent

If there's no concrete anchor (specific edit, chosen option, phrasing under review), stop and tell the user this skill needs a candidate to critique.

Otherwise, spawn one subagent — or more if the user explicitly asks for multi-reviewer (R0/R1/R2) — with a briefing containing exactly:

• Context — file path(s), surrounding code/prose, constraints.
• Problem statement — what the proposal is trying to solve and why this approach.
• The proposed fix — verbatim.
• What's already ruled out — alternatives the user has considered and rejected, with the reason.
• The 3-part ask.
