This is a coherent documentation crawler/search skill, but it deserves review because it can crawl arbitrary documentation sites, cache their contents locally, and optionally send browser-rendering requests and tokens through a configurable gateway.
Install only if you are comfortable with a tool that makes outbound requests to configured or supplied documentation URLs and stores scraped text locally. Prefer the virtual environment install, avoid using it on confidential or authenticated docs unless that caching is approved, clear ~/.anydocs/cache when needed, and only use browser rendering with trusted local or HTTPS gateways and protected tokens.
