Agent Skills: review-plan

Review a plan for architectural, DRY, scope, and UX concerns before implementation starts. Covers IMPLEMENTATION_PLAN_*.md / REFACTOR_PLAN_*.md files AND in-conversation plans drafted in Claude Code plan mode (ExitPlanMode) or inline messages. Use when user asks to "review the plan", "analyze the plan", "critique the plan", "is this plan good", or wants a senior engineer / product manager pass over a planning document. For creating a plan from scratch use plan-implementation or plan-refactor. For reviewing code or a PR use review-code.
