ask-a-council

Convene several harnesses or models against one question, each given a distinct lens it can fail on, before an artifact becomes load-bearing and being wrong is expensive. Use when the failure modes genuinely differ in kind — a single reviewer's prompt would only catch what its own lens looks for. Not for a question a command settles (just run it); not for one reviewer's prompt (sanity-check owns that); not for dispatch mechanics or isolation boundaries (dispatching-subagents owns those); not for trusting a verdict already returned (verify-the-instrument owns that).
