Adversarially critique a proposal by generating alternatives. Dispatches 3 parallel critics (pragmatist, paranoid, architect lenses) — each invents one alternative approach — then a synthesis step ranks all 4 options and recommends the top choice. When the proposal was authored by someone other than the agent (inherited plan, someone else's PR, external review), a 4th steelman critic runs in the same parallel wave and strengthens the original first, so it is judged at its strongest rather than its weakest. Use when a plan, fix, scoping, decomposition, or named recommendation will drive decisions and you want structured alternative-generation before committing. Complements /shadow-verify — that skill re-derives factual claims; this one critiques whether the chosen approach itself is best.
