Produces a severity-rated (高/中/低) Clean Code findings report across 7 dimensions (naming, function size/SRP, duplication/DRY, over-engineering/YAGNI, magic numbers, structural clarity, project conventions), each with a location and a behavior-preserving refactor suggestion — never changing functionality. Use whenever the user asks for a code review, quality check, refactor advice, or code-smell / Clean Code analysis, OR points at a file/function/diff and asks if it is well-written, too long, too repetitive, over-engineered, or poorly named — even casually, and even if they never say "review" ("I just wrote this, look it over", "does this look good before I commit"). Trigger on 代码体检, 代码质量, 重构检查, 代码审查, 这段代码写得怎么样, 帮我看看代码有没有问题, 有没有坏味道, 这函数是不是太长了, 命名规范吗, 魔法数字, 重复代码, 过度设计, and English like "is this code clean", "any code smells", "check this file".
Generate a magazine-quality visual card as a single self-contained HTML file (embedded CSS, Swiss-grid + bold-type design system), then screenshot it to a shareable PNG and hand back both files. Use this whenever the user wants content turned into a visually rich card or shareable image — even if they don't say the word "card." Triggers: make/create/generate/design a visual card, info card, knowledge card, quote card, social card, summary/takeaway/cheatsheet card; 信息卡, 知识卡片, 金句卡, 语录卡, 做张卡片, 设计一张卡片, 把这段内容做成卡片, 把要点排成一张图, 总结成一张图, 小红书封面, 公众号封面图, 朋友圈配图. Prefer this over generic HTML/frontend skills when the goal is one decorative card image. When the content is a multi-section report instead of a single card, use hai-visual-report.
