Agent Skills: decision-memo-builder

Builds a 1-page decision memo (context → options → recommendation → risks → ask) enforcing McKinsey memo DNA — brutal brevity, SCP storyline clarity, decision-forcing output, evidence density. Use when drafting a memo for a leadership decision, a scope cut, a buy/build/partner call, a roadmap slip, or any "should we X?" moment that needs a yes/no from a specific person by a specific date.
