Specialization of playwright-harness for capturing an ANIMATED GIF of web content: drive a page/canvas/WebGL animation, grab a sequence of frames, and encode a looping GIF. Use when the task is "make a gif of this", "grab a gif of the demo/animation/shader", "record the canvas as a gif", or "capture a looping clip for a PR/README/issue"; any time a still screenshot is not enough. Read playwright-harness FIRST for script conventions and execution. For the quality/size dials…
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
# GIF Capture: specialization of playwright-harness **Read `playwright-harness` first.** The base owns prerequisites, the run pattern (write to `/tmp/pw-*.mjs`, run with `playwright` resolvable), and the drive/assert + WebGL-GPU patterns. This skill changes only how you turn a running animation into frames. Encoding and the quality/size tradeoffs live in **`references/gif-optimization.md`**; open it before tuning, since a deep-fried, janky, or oversized GIF is easy to make by accident. **Headless is required here** (not just the default): the encode is offline and you want clean, chrome-free frames. ## Prerequisites (in addition to the base) - `ffmpeg` to encode frames/video into a GIF; `npm i ffmpeg-static` in a /tmp dir gives a binary path, no system install. - For tuning, `gifski` (best on gradients) and `gifsicle` (size reduction); see `references/gif-optimization.md`. ImageMagick is an optional alternative. ## Capture the frames. Two ways. ### A. Frame-by-frame screenshots (default) The default for canvas, WebGL, or any clock-driven animation. Drive the clock yourself, one frame at a time, and screenshot each step: deterministic (same …

How to install
mdr add simiancraft/simiancraft-skills/playwright-gif-capture@sha256:9989fc02f44be0a2The line at the top of this page pins the label git:20260614.1196744, 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.
