# Catalog patterns: adopt behavior, not incompatible code

The Hermes Skills Hub search field returned **three** results for `animejs` on 2026-10-23. All three source packages were downloaded and inspected locally. These are source-inspection verdicts, not claims that the peer applications were executed.

| Source | Relative verdict | Useful advantage | Limitation vs presentation-html |
|---|---|---|---|
| presentation-html baseline 563aaf4 | Reference | Offline Reveal + pinned Anime v4, accessible nodes, mechanism demo and browser QA | Entry timelines were disposable; no deterministic seek/replay regression suite or compact SVG/grid recipes |
| [ClawHub animejs 1.0.0](https://clawhub.ai/skills/animejs) | Specialist: stronger clock contract | Explicit paused-instance registry and externally driven seeking | HyperFrames-specific; basic/timeline snippets use v3 `anime()` / `anime.timeline()` despite a v4 CDN URL; no portable Reveal deck |
| [freshtechbro/claudedesignskills](https://github.com/freshtechbro/claudedesignskills/tree/1da73febff0c3e1dfefc07f8a5ef8f7d1dfdb6cd/plugins/individual/animejs/skills/animejs) | Specialist: broader choreography recipes | Timeline presets and spatial stagger guidance | Skill and Python timeline generator emit legacy v3 syntax; web hero/modal/loader presets are not a presentation narrative |
| [bowtiedswan/animejs-skills](https://github.com/bowtiedswan/animejs-skills/tree/cf2bed8d6654a6cfd02d3ff11b74ff3a7a7631e2) | Specialist: broader v4 API reference | SVG drawing/motion paths, grid stagger, scope lifecycle and seek API coverage | Not an offline deck builder; unpinned CDN examples and some namespace claims must be checked against the installed UMD runtime |

## Adopted capabilities

| Capability | Best evidence | Native destination | Excluded | Acceptance gate |
|---|---|---|---|---|
| Explicit animation ownership and deterministic seeking | ClawHub SKILL.md contract | assets/app.js: paused timeline Map, seek/replay/settle | HyperFrames registry/runtime, GSAP replacement and wall-clock callbacks | Forward → backward → same-time DOM equality; active clock paused |
| Meaningful named beats | Freshtechbro timeline guidance and timeline_builder.py | assets/app.js sequence labels; references/choreography.md | v3 generated code, modal/loader choreography as deck default | Real v4 playback plus replay/departure/revisit tests |
| Vector flow and spatial order recipes | Bowtiedswan SKILL.md and references/examples.md | references/choreography.md + scripts/test-motion.mjs | Unpinned CDN, scroll-driven slide navigation, perpetual waves | SVG draw/path and six-cell grid execute offline against vendored 4.5.0 |
| Cleanup under state changes | Explicit-clock contract plus reference lifecycle gaps | assets/app.js overview/visibility settling | Global engine pause affecting unrelated scenes; blanket transform removal | Overview/reduced-motion/print regression checks; final state retained |

Reveal.js 6.0.2, Anime.js 4.5.0, the dependency-free Python builder, native DOM/SVG and single-file offline delivery remain unchanged. No new runtime dependencies. Existing assembly/inspection behavior is retained rather than replaced. Accessible motion remains an enhancement; source availability does not establish a missing capability or justify removing existing QA.

No peer source files, generators, artwork or installation scripts are redistributed or run. New examples are original implementations using the already-licensed Anime API. Runtime tests establish our recipes' compatibility, not correctness of every upstream example. HyperFrames itself was not installed or validated. Morphing, drag/scroll interaction and split text remain optional techniques, not newly claimed working features.
