This skill should be used when the user asks to "audit a plugin", "review plugin quality", "audit plugin content", "đánh giá chất lượng plugin", "audit plugin này", "kiểm tra chất lượng plugin", or wants a multi-round independent content audit of a Claude Code plugin (plugin.json, SKILL.md, references, examples, hooks, commands). Runs deep review → independent validation → user-gated fixes → fresh-review convergence loop → optional headless benchmark. Not for plan files (use /audit-plan) or application source code (use /audit-logic).
