Plan Critic is a high-quality Claude Code skill (quality score 95/100) in the agents-skills-meta sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/plan-critic/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when a plan has been generated (Plan Mode output, ExitPlanMode, pasted plan text, or plan file path) and needs review before code is written. Triggers on "critique this plan", "review this plan", "is this plan good", "poke holes in this plan", "should I approve this plan", or sharing a plan for evaluation.
