Create and expand w.wiki short URLs (Wikimedia's URL shortener) — redirect behavior, the missing expansion API, the browser CORS trap, server-side resolution patterns, and creation via the meta.wikimedia.org API.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Wikimedia URL Shortener (w.wiki) > ⚠️ **User-Agent required:** All requests to `w.wiki` and `meta.wikimedia.org` > need a descriptive User-Agent. See the > **[wikimedia-api-access](../wikimedia-api-access/SKILL.md)** skill. ## What It Is **w.wiki** is the Wikimedia Foundation's URL shortener, built on the [Extension:UrlShortener](https://www.mediawiki.org/wiki/Extension:UrlShortener) extension. Short URLs look like `https://w.wiki/TR9R` (or bare `w.wiki/TR9R`) and **301-redirect** to the target URL. - **Create** short URLs at `https://meta.wikimedia.org/wiki/Special:UrlShortener` or via the API (below). Requires edit rights on Meta-Wiki. - **Expand** a short URL: **there is no expansion API** (see Gotcha 1) — the only way is to follow the redirect. - **QR code** for any URL: `https://meta.wikimedia.org/wiki/Special:QrCode?url=<url>` (302s to a PNG). ## Quick Reference | Task | Method | |---|---| | Expand a short URL (server-side) | `curl -sI https://w.wiki/CODE` → read `location:` header (or `curl -sL` to follow) | | Expand in Node | `await fetch(url)` — `resp.url` is the final target after redirects | …

How to install
mdr add fuzheado/wikipedia-ai-skills/wikimedia-url-shortener@sha256:300e49f0e327cde5The line at the top of this page pins the label git:20260813.957079d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
