What's inside
- Skill name
contrary- Description
- Adversarial devil's advocate. Use when the user wants their idea, plan, PR, code review, architectural decision, or claim deliberately attacked — 'poke holes in X', 'tell me why I'm wrong about Y', 'red-team this', 'what am I missing'. Distinct from /ask (neutral), /plan (constructive), /brainstorm (open exploration), /review (structured code review). Use when the user explicitly wants pushback.
