Build or review GSAP animation in Astro projects: page transitions under the ClientRouter (formerly ViewTransitions), an outro that finishes before the swap through astro:before-preparation, cleanup in astro:before-swap, initial state on the incoming document, setup that rehooks on astro:page-load, transition:persist and persisted islands, choosing between transition:animate and GSAP per element, back and forward, prefetch, scroll and focus, animated show and hide, and scroll-driven effects.…

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

# GSAP Astro

Every animated page or component runs through the same lifecycle:

**mount → initial state → intro → settled → outro → end state → unmount**

Astro renders pages to HTML on the server. Without `<ClientRouter />` the browser owns mount and unmount and the site is a plain multi-page site: everything in `gsap-vanilla` applies unchanged, including first paint, `pageswap` and `pagereveal`, the bfcache, and prerendering. With `<ClientRouter />` the document persists and the router swaps `<head>` and `<body>` in place: mount is the swap, unmount is the next swap, and module scripts, listeners, and timelines survive both. The five phases between belong to your animation code. This skill covers what Astro changes: where the outro runs, what survives a swap, what runs again, and what must be cleaned up. The user's request and the existing design decide how things look.

How to install

The exact contents, by fingerprint
mdr add ucsandman/claude-skills/gsap-astro@sha256:388d7556b61bcc77

The line at the top of this page pins the label git:20260915.793ae04, 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.
