Fetches an arXiv paper — metadata (title, authors, abstract) via WebFetch on the abs page, plus the full PDF via curl on arxiv.org/pdf and structured extraction by pdfvision. Use when the URL is in the form arxiv.org/abs/{paper_id}.

Reads GitHub via the gh CLI — repo metadata / README / file tree, issues with comments and timeline, pull requests (diff, files, inline comments, GraphQL review threads with isResolved / isOutdated), discussions (GraphQL), code (file contents and code search), and releases (with tarball / zipball fallback). Routes by URL shape into references/{topic}.md so only the relevant command sheet is loaded. Use when the URL is on github.com.

Fetches MDN Web Docs as raw Markdown by mapping the developer.mozilla.org URL to its source file in mdn/content (en-US) or mdn/translated-content (other locales) on GitHub and curl-ing the raw blob. Cleaner and more compact than rendering the SPA page; falls back to WebFetch on the original URL when the path mapping 404s. Use when the URL is on developer.mozilla.org.

Extracts text (with original line breaks), metadata, per-page character / image density, and optional rendered PNGs from a PDF using pdfvision. Falls back to --render on pages whose density Overview shows low text coverage so multimodal models can read raster slides. Use when the URL ends in .pdf, the user supplies a local PDF path, or another readable-* skill produced a PDF that still needs structured extraction.

Fetches a SpeakerDeck slide deck by extracting the public PDF URL from the slide page (WebFetch), downloading it via curl, and running pdfvision — typically with --render on image-heavy pages so the slides can be read visually. Use when the URL is in the form speakerdeck.com/{user}/{slug}.

Reads web platform specifications via WebFetch — uses the multipage HTML variant for the WHATWG HTML spec, anchor-targeted section reads for W3C TR documents and TC39 / ECMAScript. Returns the relevant section rather than the whole spec, since these documents are too large for a single fetch. Use when the URL is on *.spec.whatwg.org, w3.org/TR/, or tc39.es.

Fetches a Stack Overflow question body and its answers via the Stack Exchange API (api.stackexchange.com/2.3 with the withbody filter, gzip-compressed). Anonymous quota is 300 req/day per IP; honor the response backoff field. Surface the question URL when displaying content (CC BY-SA attribution). Use when the URL is in the form stackoverflow.com/questions/{id}/...

Automates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, or extract information from web pages.
