The first command installs just this skill, by the name in its SKILL.md; the second installs the whole repository.

A dense canopy of textured leaves sweeps across the frame with shallow depth of field, then parts to uncover the first headline; a second, depth-lifted batch carries the second headline past the camera. A handful of leaves stay behind on the type and keep a light breeze. Font, weight, size, letter spacing, leaf counts, sweep speed and the retained-leaf breeze are variables.

Composition id: canopy-part-title. Duration 12 s at 30 fps, 1920×1080.

Install

Install with npx hyperframes add canopy-part-title; by default the files above land under compositions/canopy-part-title/. Then mount the block from the host index.html:

<div
  data-composition-id="canopy-part-title"
  data-composition-src="compositions/canopy-part-title/canopy-part-title.html"
  data-start="0"
  data-duration="12"
  data-track-index="1"
  data-width="1920"
  data-height="1080"
></div>

Render with custom values by targeting the composition file directly:

npx --yes hyperframes@0.8.12 render 'compositions/canopy-part-title/canopy-part-title.html' --variables '{"headline1":"Understory","headline2":"Move slowly"}'

Variables

Read at runtime via window.__hyperframes.getVariables(); declared on the composition root as data-composition-variables (single-quoted attribute, plain JSON).

id	type	default	label / range
`headline1`	string	`"Understory"`	Headline 1
`headline2`	string	`"Move slowly"`	Headline 2
`font`	string	`"Helvetica"`	Headline font
`fontWeight`	number	`900`	Font weight 100–900 step 100
`fontSize`	number	`1`	Font size (1 = auto-fit) 0.3–2 step 0.01
`letterSpacing`	number	`0.01`	Letter spacing (em) -0.2–1 step 0.01
`background`	color	`"#020805"`	Background
`leafCount`	number	`170`	Leaves per sweep 40–320 step 1
`stayCount`	number	`5`	Leaves left behind 0–20 step 1
`sweepSpeed`	number	`1`	Sweep speed 0.3–3 step 0.05
`retainedBreeze`	number	`1`	Retained leaf breeze 0–2 step 0.05

Runtime contract

One paused GSAP timeline registered as window.__timelines["canopy-part-title"].
Re-syncs on the hf-seek CustomEvent; every frame is a closed-form function of time (seeded PRNG only, no rAF loops, no Date.now).
Renderer: three.js 0.170.0, GSAP 3.14.2, Canvas 2D, Post-processing, Seeded PRNG, Shadow maps. Budget roughly 350 MB per live instance; run one at a time.

Editing rules (from the source project)

Keep data-composition-variables a single-quoted attribute with plain " JSON. Never save it through Studio’s Design panel.
Do not put <canvas> in static markup; create it at runtime.
Keep every visual state a function of t; seek-safety is what makes the block renderable.

Colophon for this issue

How this issue was made

Source

github.com/heygen-com/hyperframes, branch main, last pushed 23 September 2026.

Licence

Apache-2.0 — the text of every skill is reproduced unmodified, frontmatter included, under the upstream licence.

Discovery

34 skills found by walking the repository tree for SKILL.md, not by matching a directory convention. 3 distinct layouts observed: .agents/skills/*/SKILL.md, registry/blocks/*/SKILL.md, skills/*/SKILL.md.

Duplicates collapsed

6 mirror copies folded into their canonical skill — republished for Claude. Copies match on content hash and on position once a leading per-agent prefix is stripped, because the same skill is routinely shipped under a dozen agent directories with a dozen different hashes.

Issue colours

Resolved from a design.md in this repository — hue 293°, chroma 0.190. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Heading repairs

1 repair applied to this skill so the document has one h1 and no skipped levels:

Removed “Canopy Part Title”, a leading h1 that duplicated the skill title.

Spec compliance

Every skill satisfies the Agent Skills specification’s frontmatter rules.

Images

Images inside a skill come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.

Marketplace

A plugin manifest is published at .claude-plugin/marketplace.json by HeyGen, declaring 2 plugins. It is read for editorial metadata only — never as the skill index, which is always the repository tree.

Signal

Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.

Agent surfaces

The whole issue is available as one markdown document at /heygen-com/hyperframes.md, and each skill at its own .md URL.

Publication

Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
