花叔的「md/html/docx 多向流水线」skill，四个能力 + 两种模式：(1) 用Microsoft markitdown把任意文件（PDF/DOCX/PPTX/XLSX/HTML/图片/音频/YouTube/EPub/ZIP）转成干净的md；(2) 用Pandoc + 4套精挑模板把md加工成出色的html——**兜底模式**（不耗token，pandoc 一键套版）+ **视觉艺术设计师模式**（AI 读懂内容、推荐 3 个差异化方向、为内容定制视觉表达），继承huashu-design的反AI slop审美；(3) 用html-to-markdown + trafilatura把html或URL无损转回md；(4) 用python-docx把md加工成出版社级docx（专业排版+自动嵌图+封面目录页眉页脚，专用于纸质书审校/投稿/出版交付）。落地花叔的「md生产，多端消费」方法论。触发词：md转html、html转md、pdf转md、docx转md、pptx转md、xlsx转md、文件转md、URL转md、文档转md、转markdown、做html、生成html、网页转md、import文档、导入md、导出html、md to html、html to md、any to md、md转docx、md to docx、生成docx、做word文档、出版社审校、投稿、纸质书、出版稿、交付docx、book、出色的html、定制html设计、做个好看的网页、设计师模式、几种风格、推荐设计方向、markitdown、pandoc、python-docx。即使用户只是说「这个PDF变md」「这篇md做成网页」「这个网页存下来」「把这些md做成可投稿的word」「给出版社一份审校稿」「给这个md做个出色的html」「让我看看几种风格」也应触发。

react patterns

Zustand 5 state management patterns. Trigger: When implementing client-side state with Zustand (stores, selectors, persist middleware, slices).

Provides the complete, verified grep scan command library for auditing React codebases before a React 18.3.1 or React 19 upgrade. Use this skill whenever running a migration audit - for both the react18-auditor and react19-auditor agents. Contains every grep pattern needed to find deprecated APIs, removed APIs, unsafe lifecycle methods, batching vulnerabilities, test file issues, dependency conflicts, and React 19 specific removals. Always use this skill when writing audit scan commands - do not rely on memory for grep syntax, especially for the multi-line async setState patterns which require context flags.
