SkillMOO is the independent evaluator: we never modify a third-party author's original work — grading and rewriting the same artifact would compromise the independence this rating stands on. One-click optimize runs only on YOUR copy: paste this skill's SKILL.md into the free detector to get an engine-verified optimize of your copy. Authors: fix the review findings above at the source — we re-grade on every refresh and this page updates automatically.SkillMOO 是评级方：我们从不改动第三方作者的原作 —— 既当裁判又动手改，评级的独立性和公信力就没了。「一键优化」只作用于你自己的副本：把这份 SKILL.md 粘贴到免费检测页，即可获得经引擎逐项校验的一键优化。若你是作者，按上方「评测结果」在源头逐条修复即可 —— 我们会重新评级，本页自动更新。

Anti-forgery: the badge is rendered live by skillmoo.com, carries this skill’s NAME inside it, and links back to this page — hotlinking someone else’s badge shows the wrong name in plain sight, and one click lands on the real rating. It updates automatically whenever we re-grade.防伪说明:徽章由 skillmoo.com 实时渲染,图内自带本 skill 的名字并链回本页 —— 冒用他人徽章会当场显示对方的名字,读者一点即达真实评级页。我们重新评级时徽章自动同步。
