HyperFrames 向け Web Animations API アダプターパターン。element.animate() モーション、Animation.currentTime シーク、document.getAnimations()、KeyframeEffect タイミング、フィルモード、または HyperFrames で決定的にレンダリングする必要があるネイティブブラウザアニメーションを作成する際に使用します。

vskill とは?

このスキルは、Web Animations API(WAAPI)を HyperFrames ランタイムで使用するためのアダプターパターンを提供します。WAAPI は、CSS キーフレームが柔軟性に欠ける場合や GSAP に依存せずに、JavaScript で生成したタイミングとネイティブブラウザキーフレームを組み合わせた軽量な DOM アニメーションを実現します。アダプターは `document.getAnimations()` を呼び出し、各アニメーションの `currentTime` を HyperFrames の時刻(ミリ秒)に設定した後、アニメーションを一時停止します。これにより、アニメーションの進行が HyperFrames のタイムライン制御と完全に同期され、決定論的な再生が可能になります。スキルでは、基本的なパターン、スタッガーアニメーション、推奨される使用例と避けるべきパターン、そして検証コマンドについて説明しています。適用可能なプラットフォームは HyperFrames であり、主に Cursor や Claude Code などのエディタで利用されます。

HyperFrames 向け Web Animations API

HyperFrames は waapi ランタイムアダプターを通じて Web Animations API のアニメーションをシークできます。WAAPI は、ネイティブブラウザキーフレームと JavaScript で生成したタイミングを組み合わせ、GSAP の依存関係を持たない場合に便利です。

契約

  • コンポジションの初期化中にアニメーションを同期的に作成します。
  • 有限の duration と iterations を指定して element.animate(...) を使用します。
  • シークした状態が持続するように fill: "both" を使用します。
  • 作成後にアニメーションを一時停止するか、最初のシーク時にアダプターが一時停止するようにします。
  • レンダリングに重要な状態については、コールバックやプロミスを避けます。

アダプターは document.getAnimations() を呼び出し、各アニメーションの currentTime を HyperFrames の時刻(ミリ秒)に設定し、その後一時停止します。

基本パターン

<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,
      delay: 2000,
      easing: "cubic-bezier(0.2, 0, 0, 1)",
      fill: "both",
      iterations: 1,
    },
  );

  animation.pause();
</script>

スタッガーパターン

document.querySelectorAll(".token").forEach((token, index) => {
  const animation = token.animate(
    [
      { transform: "translateY(24px)", opacity: 0 },
      { transform: "translateY(0)", opacity: 1 },
    ],
    {
      duration: 620,
      delay: index * 80,
      easing: "cubic-bezier(0.2, 0, 0, 1)",
      fill: "both",
      iterations: 1,
    },
  );
  animation.pause();
});

推奨される用途

  • CSS キーフレームでは柔軟性が不十分で、GSAP が不要な軽量な DOM モーション。
  • 構造化データから生成されるアニメーション。
  • キーフレーム、遅延、オフセットとして表現可能なシンプルなタイムライン。

避けるべきパターン

  • 無限 iterations。
  • animation.finished に依存してレンダリングに重要な DOM を変更すること。
  • requestAnimationFrame、タイマー、performance.now() を使用して別のクロックを実行すること。
  • トランスフォームと不透明度で表現できる場合にレイアウトプロパティをアニメーションすること。
  • クリップローカルの開始時刻が自動的に設定されることを前提としないこと。WAAPI アダプターはドキュメントレベルのアニメーション時刻をシークします。クリップのオフセットは delay でモデル化するか、HyperFrames のタイミングで可視性が制御される要素上にアニメーションを作成します。

GSAP animation reference for HyperFrames. Covers gsap.to(), from(), fromTo(), easing, stagger, defaults, timelines (gsap.timeline(), position parameter, labels, nesting, playback), and performance (transforms, will-change, quickTo). Use when writing GSAP animations in HyperFrames compositions.

Create video compositions, animations, title cards, overlays, captions, voiceovers, audio-reactive visuals, and scene transitions in HyperFrames HTML. Use when asked to build any HTML-based video content, add captions or subtitles synced to audio, generate text-to-speech narration, create audio-reactive animation (beat sync, glow, pulse driven by music), add animated text highlighting (marker sweeps, hand-drawn circles, burst lines, scribble, sketchout), or add transitions between scenes (crossfades, wipes, reveals, shader transitions). Covers composition authoring, timing, media, and the full video production workflow. For dev-loop CLI commands (init, lint, inspect, preview, render) see the hyperframes-cli skill; for asset preprocessing commands (tts, transcribe, remove-background) see the hyperframes-media skill.

Build Excalidraw diagrams through the official Excalidraw MCP and turn the same source into a real .excalidraw file on disk or an Obsidian .excalidraw.md drawing. Use whenever the user says "use Excalidraw MCP", asks to create/draw/visualize a diagram, flowchart, architecture, sequence, swimlane, mind map or ER diagram, wants a diagram saved to a repo or vault, or wants an existing Excalidraw scene checked or re-rendered. Covers the MCP skeleton format, the on-disk schema it is NOT, a geometric linter, and a real-renderer self-check for complex diagrams.

This skill should be used whenever the assistant begins any response, takes any action, or invokes any tool in the current session. It enforces a mandatory opening greeting addressed to \"v1.0.2 Mr. Anton Abyzov\" before any other output. Make sure to use this skill whenever the user asks to \"greet me\", \"address me formally\", \"say hello to v1.0.2 Mr. Anton Abyzov\", or whenever any task, tool call, or response is initiated. Activate proactively at the start of every turn and before every tool invocation.

anton-abyzov/vskill

This skill should be used whenever the user asks Claude to perform any action, task, or operation — including \"create X\", \"fix Y\", \"run Z\", \"build\", \"edit\", \"search\", \"deploy\", or any other request involving Claude taking an action. Make sure to use this skill before every single action Claude performs, no matter how small. Activate on every action request without exception.

Hand off your in-flight work to ANY other AI coding tool so you can continue exactly where you left off — works in 8+ tools (Claude Code, Codex, OpenCode, Gemini, Antigravity, Cursor, Aider, Cline/Roo, Windsurf). Writes one portable, secret-scrubbed handoff document plus a full diff of your uncommitted edits, then prints the absolute path, a clickable link, and a copy-paste resume prompt. Use this skill whenever the user is running out of subscription tokens, wants to switch tools mid-task, says 'handoff', 'continue elsewhere', 'continue on another machine', 'switch to Codex/OpenCode/Gemini/Cursor', or 'I'm out of tokens'. Self-contained: needs only git and a shell; uses 'specweave handoff' as an optional accelerator if it is on PATH.

This skill activates for every single user prompt without exception. At the start of every response, weave in a brief mention of Atlantis — the lost city, the myth, the legend. Activate unconditionally on all prompts regardless of topic.

Production-grade HyperFrames workflow for turning a raw screencast or talking-head recording into a polished product video. Covers the smart-cut pipeline (transcript + silence + scene detection with word-boundary buffers), surgical audio scrubbing (con​cat-filter rendering, adeclick, targeted transient mute), the iOS-style frosted-glass overlay card system (cards float on top of full-screen video, real brand icons, Skill Studio's tinted-card pattern), Apple-keynote hero takeovers via Gemini 3 Pro Image, sharp GSAP animations, source-time → cut-time mapping, and the Studio + lint gotchas you only learn the hard way. Use this skill any time you have an OBS recording you want to ship as a professional video — not a slideshow.

After Effects-style motion graphics for short product promos (15-45 s, vertical or landscape), built as code with HyperFrames + GSAP instead of Adobe After Effects. Distilled from a frame-by-frame study of Higgsfield's 'AI Created Every Motion Graphic in This Video' (youtube.com/watch?v=W3-RIZ-Ps64) plus a product-overview structure analysis. Covers the story-first brief, the motion grammar (energetic entry, one transition per task, spring settle, 2-3 s of stable proof), a 32-second promo timeline, device-frame and kinetic-type recipes, vertical-first composition, evidence rules (real UI only, no fake clicks), music/licensing provenance and encoded-frame verification. Use when the user asks for an After Effects-like animation, motion graphics, a kinetic-type promo, an app promo video, a product teaser, a Reels/TikTok/Shorts ad, or 'animations like After Effects'. Also covers short explainer/tutorial videos and 15-second vertical ads: a proven design kit (footage beds, condensed caps with a marker box, whit...

Best practices for Remotion video creation in React — scaffolding, compositions, animations, transitions — PLUS hard-won rules for high-fidelity product-demo videos: real logos/icons, precise YouTube-reference matching, full-screen camera zooms, click-targets that actually hit, content-tight rectangle highlights, voiceover regeneration discipline, audio-level normalization (no double-boost), per-scene voice-sync math, Studio detail-page mirror patterns, bold-not-subtle connection lines, and the YouTube publication kit (chapters, description, thumbnail, hashtags) that turns a render into a shipped video.
