web-kit

Aggregate web search across 20+ engines (Google, Google Scholar, Semantic Scholar, arXiv, GitHub, Reddit, etc.). Returns titles, URLs, and snippets. Use for: fact lookups, background reading, finding academic papers or citations, locating repos/packages/APIs, checking recent news, and gathering community discussions or comparisons. Trigger keywords: "search," "look up," "find," "查," "搜," "找," "有没有," and similar. Supports category, language, and single-engine selection when the default Google engine is not enough. Do not use for local file search (use grep), repo-level search (use gh CLI), or in-repo doc search.

Fetch web content via a real Chrome browser (JS rendering, anti-scrape bypass, login cookies). Two modes: `page` renders a URL to markdown (read article/docs/SPA content); `file` downloads a URL to a raw file (PDF/zip with auth/cookies). Use `page` when you want to read page content; use `file` when you want to save the resource. Trigger keywords: "read this page", "fetch this page", "scrape this page", "cloudflare", "page blocked", "读一下这个网页", "抓取这个页面", "下载PDF", "下载文件", "download file", "download this". Needs CDP_URL + WEB_KIT_API_KEY.
