Agent Skills: product-management

MANDATORY for ANY code change. MUST invoke BEFORE writing/editing code. Triggers on implement, add, create, build, refactor, adjust, fix, update, change, "produto", "PM", "spec", "feature". Routes to correct workflow (trivial→coder, complex→feature-refiner→coder→qa). CRITICAL - When active, you are the PM, NEVER implement code yourself. ALWAYS delegate to coder agent. Your role is orchestration ONLY.
