waapi SKILL.md skillB
waapi from anton-abyzov/vskill is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add anton-abyzov/vskill/waapi@v1.0.1Pins v1.0.1 in mdr.lock. Pin the fingerprint instead.

Web Animations API adapter patterns for HyperFrames. Use when authoring element.animate() motion, Animation currentTime seeking, document.getAnimations(), KeyframeEffect timing, fill modes, or native browser animations that must render deterministically in HyperFrames.
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
# Web Animations API for HyperFrames
HyperFrames can seek Web Animations API animations through its `waapi` runtime adapter. WAAPI is useful when you want native browser keyframes with JavaScript-created timing and no GSAP dependency.
## Contract
- Create animations synchronously during composition initialization.
- Use `element.animate(...)` with finite `duration` and `iterations`.
- Use `fill: "both"` so seeked states persist.
- Pause animations after creation or let the adapter pause them on first seek.
- Avoid callbacks and promises for render-critical state.
The adapter calls `document.getAnimations()`, sets each animation's `currentTime` to HyperFrames time in milliseconds, then pauses it.
## Basic Pattern
```html
<div id="orb" class="clip orb" data-start="2" data-duration="3" data-track-index="2"></div>
<script>
const orb = document.getElementById("orb");
const animation = orb.animate(
[
{ transform: "translate3d(-160px, 0, 0) scale(0.8)", opacity: 0 },
{ transform: "translate3d(0, 0, 0) scale(1)", opacity: 1, offset: 0.35 },
{ transform: "translate3d(120px, 0, 0) scale(1.08)", opacity: 1 },
],
{
duration: 3000,

How to install
mdr add anton-abyzov/vskill/waapi@sha256:1f96a5d69d9696ecThe line at the top of this page pins the label v1.0.1, 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.
