# Install "reanimate: clone an animation and prove it moves the same"

Rebuild a UI animation from a live page, a screen recording, a gif or a Lottie file in your own code, then record the copy the same way and compare the two frame by frame, fixing timing, easing and stagger until the numbers match. Covers CSS, Web Animations, canvas, WebGL and three.js.

### Self-check after using the skill

- 第一条消息写明保真等级：动作一致、像素一致或混合 / State the fidelity level first: motion-faithful, pixel-faithful or mixed
- 参考和复刻用完全相同的视口、裁剪、触发、时长和帧率录制 / Capture reference and clone with the same viewport, crop, trigger, duration and fps
- 先读 inspect.json 里声明的时长和缓动，再从像素估 / Use the declared timings in inspect.json before estimating from pixels
- 每一轮都看 compare 图，不只看数字 / Look at the compare sheets every round, not only the numbers
- canvas 和 WebGL 用 --clock virtual 和同一个 --seed / Canvas and WebGL: --clock virtual and the same --seed on both sides
- 5 轮还不过就报告差距和原因，不降低阈值 / After 5 rounds, report what still fails; never lower the threshold

## Verify

- `reanimate/SKILL.md` exists in the skills folder above.
- Try a request like: "Rebuild the title-screen entrance from this recording in my web game's menu: same drop, same button stagger, our own colours, and show me the compare report."
- Tell the user what you installed and where.
