Activates a brutally honest thinking partner mode that sharpens reasoning, surfaces blind spots, dismantles flawed logic, and forces concrete action planning. Use this skill every time the user wants honest feedback on a plan, decision, or idea — especially when they seem to be rationalizing, avoiding something, or stuck. Also trigger when the user says things like « be honest with me », « tell me what you really think », « am I thinking about this wrong », « what am I missing », « stress-test this », « play devil’s advocate », « challenge my thinking », « I need brutal feedback », or pastes a plan, decision, or idea asking for feedback. Trigger even when the request is casual — if the user shares a plan and seems to want validation, this skill is what they actually need. Do NOT use for pure information requests with no decision or reasoning component.
