Hyperframes motion

Skill Sma1lboy/rove/.claude/skills/hyperframes-motion

All animation knowledge for HyperFrames — atomic motion rules, multi-phase scene blueprints, scene transitions, broader motion-design techniques, AND the seven runtime adapters (GSAP default, plus Lottie, Three.js, Anime.js, CSS keyframes, Web Animations API, TypeGPU). Use for any motion or animation task: pick 2-4 rules and compose, or load a blueprint, or look up runtime-specific API (e.g. GSAP eases / Lottie player / Three.js mixer). HyperFrames-native: single paused timeline, seek-safe, deterministic.From its SKILL.md

HyperFrames Motion

All motion knowledge in one skill: rules (atomic recipes), blueprints (multi-phase scene templates), transitions (scene-to-scene), techniques (broader motion-design patterns), and adapters (per-runtime APIs).

For the composition contract (data attributes, sub-compositions, determinism) see /hyperframes → core/.

Default: compose atomic rules

Pick 2-4 rules from rules-index.md, glue them together with a single paused GSAP timeline, done. This is faster and produces less code than starting from a blueprint.

Load a blueprint when

The scene matches an existing pre-designed multi-phase template (brand-reveal, social-proof, demo-page-scroll-spotlight, etc.) and reusing its phase pipeline saves real authoring time
You want runnable ground-truth code for a complex 4-5 phase choreography

Blueprints live in blueprints-index.md. Each entry points to blueprints/<id>.md (recipe) and examples/<id>.html (runnable sample). Do not read it speculatively; load it when you've already decided you need scene-level orchestration.

Picking a runtime

GSAP is the default for 95% of motion work — covers timeline orchestration, transforms, easing, stagger. All atomic rules in this skill are GSAP-based.
Lottie when an asset has its own pre-baked timeline (typically After Effects exports).
Three.js for 3D scenes, camera motion, shader-driven visuals.
Anime.js for lightweight tweening when GSAP is overkill.
CSS for simple repeated motifs, decoration, shimmer — no JavaScript animation cost.
WAAPI for native browser keyframes without a GSAP dependency.
TypeGPU / WebGPU for GPU-rendered canvases (particles, liquid glass, custom shaders).

Multiple runtimes can coexist in one composition. Each registers its instances on the runtime-specific global so HyperFrames can seek all of them in one pass.

Critical Constraints

Prerequisite: /hyperframes/core → Non-Negotiable Rules (single paused timeline, data-duration governs length, no Math.random / Date.now / performance.now, no repeat: -1, no gsap.set on later-scene clips, no display / visibility animation, no timeline construction inside async / setTimeout / Promise). Don't restate those here.

Animation-craft additions on top of core's contract:

Pre-calculated layout constants — never derive positions from getBoundingClientRect() at tween time. Tween-time DOM measurements desync because the renderer samples in parallel; compute coordinates once at composition setup and reuse.
Spatial motion uses GSAP transform aliases only (x, y, scale, rotation). Core's allowlist also permits opacity / color / backgroundColor / borderRadius for non-spatial property tweens — but never width / height / top / left for layout changes.

Scripts

node skills/hyperframes-motion/scripts/animation-map.mjs <composition-dir> \
  --out <composition-dir>/.hyperframes/anim-map

Reads every GSAP timeline registered on window.__timelines, enumerates tweens, samples bboxes, computes flags, outputs animation-map.json. Use it to audit choreography (dead zones, stagger consistency, lifecycle warnings) after authoring.
