The HyperFrames composition contract — build one renderable project. Use for composition structure, the `data-*` timing attributes, `class="clip"`, tracks, sub-compositions, variables, framework-owned media playback, deterministic-render rules, and validation. Also covers Tailwind projects and the STORYBOARD.md / SCRIPT.md plan formats. Read before writing composition HTML.

What does this agent skill do?

HyperFrames Core

HyperFrames renders video from HTML. A composition is an HTML file whose DOM declares timing with data-* attributes, whose animation runtime is seekable, and whose media playback is owned by the framework.

This skill is the technical contract — how to build one hyperframes project. The body below is the build guide; per-topic detail lives in references/ (index next), read on demand. Other concerns live in the sibling domain skills — hyperframes-animation, hyperframes-creative, media-use, hyperframes-cli, hyperframes-registry. The capability map in /hyperframes says what each one covers.

References

File	Read it to…
`references/minimal-composition.md`	start from the smallest renderable composition skeleton
`references/composition-patterns.md`	choose monolithic vs modular; structure a modular `index.html`; pick a sub-comp archetype
`references/data-attributes.md`	look up any `data-*` (root / clip / sub-comp host / legacy aliases); use `class="clip"`
`references/tracks-and-clips.md`	pick `data-track-index`, handle same-track overlap / z-index, time a clip relative to another
`references/sub-compositions.md`	wire a sub-composition (host attrs, `<template>`, per-instance vars) and animate inside it
`references/variables-and-media.md`	declare variables; place `<video>`/`<audio>`, set volume, trim
`references/determinism-rules.md`	build a seekable timeline; determinism bans; the animatable-property allowlist; layout / text fit
`references/full-screen-motion.md`	author full-frame motion with shared backgrounds
`references/storyboard-format.md`	author a `STORYBOARD.md` plan (+ the parsed manifest)
`references/brief-contract.md`	conduct a creation workflow's intake — interaction mode (collaborative / autonomous), shared brief fields, asking rules
`references/script-format.md`	author the optional `SCRIPT.md` locked narration
`references/subagent-dispatch.md`	map subagent dispatch verbs (parallel fan-out / background / wait) to your harness
`references/tailwind.md`	work in a Tailwind v4 project (`init --tailwind`; runtime contract differs from Studio's v3)

For animation runtime specifics (GSAP API, Lottie, Three.js, etc.) go to hyperframes-animation → adapters/<runtime>.md.

Building a composition

Two root forms (not interchangeable)

Standalone (top-level index.html) — root <div data-composition-id="…"> sits directly in <body>, no <template> wrapper (wrapping it hides all content and breaks rendering).
Sub-composition (loaded via data-composition-src) — root must be wrapped in <template>.

⚠ Transport rule: the runtime only clones <template> contents; everything outside (incl. <head> styles/scripts) is discarded — put <style>/<script> inside the template. ⚠ Host-id rule: the host slot's data-composition-id must exactly equal the inner template's data-composition-id and the window.__timelines["<id>"] key — no -mount/-slot/-host suffix.

File shape, host wiring, and the pre-render checklist → references/sub-compositions.md.

Root must be sized (silent layout bug)

The standalone root needs an explicit sized box (width/height in px), and every ancestor down to a height:100% element must have a resolved height — otherwise a flex/100% child collapses to ~0 and content piles into the top-left corner. lint/validate/inspect do not catch this. Skeleton → references/minimal-composition.md.

One paused timeline

Each composition registers exactly one gsap.timeline({ paused: true }) at window.__timelines["<id>"] (key = root data-composition-id), built synchronously at page load. Render duration = root data-duration, not timeline length. Don't manually nest sub-timelines into the host. Full contract (incl. non-GSAP runtimes) → references/determinism-rules.md + hyperframes-animation/adapters/.

Non-negotiable rules (silent bugs `lint`/`validate`/`inspect` won't catch)

Surfaced here; full rationale in the linked reference. Do not violate:

No render-time clocks / unseeded Math.random / network / input-state; no repeat: -1 (use a finite count). → determinism-rules.md
Animate only the visual-property allowlist; never display/visibility; no gsap.set on later-scene clips. → determinism-rules.md
No <br> in body text; transformed elements must be block-level + sized; pulsing absolute decoratives need peak clearance. → determinism-rules.md
<video>/<audio> must be a direct child of the host root (never inside a sub-comp <template>/wrapper); the framework owns playback. → variables-and-media.md
Every id must be unique across the assembled page; inside a sub-comp, prefix ids with the composition id (#<id>-hero). Duplicate <video>/<img> ids render blank — the producer injects frames by getElementById, and cross-file dupes slip past lint. → composition-patterns.md
A full-screen scene fill goes on a full-bleed child (position:absolute; inset:0), never on the composition root itself — the producer's frame compositing can drop the root element's own background (the frame renders black) even though preview/snapshot show it correctly. → composition-patterns.md

Editing existing compositions

Read the files first. Preserve unrelated timing, tracks, IDs, variables, media paths.
Match existing composition IDs and timeline keys.
Adding a clip: pick a non-overlapping data-track-index or adjust surrounding timing intentionally.
data-hidden on any composition element hides it in BOTH preview and render, overriding its time window; it is non-destructive/reversible and toggled by Studio's timeline eye icon.
Adding a sub-composition: verify its internal data-composition-id before wiring the host.

Validation

Use hyperframes-cli for command details

npx hyperframes lint passes (0 errors)
npx hyperframes validate passes (0 console errors)
npx hyperframes inspect passes (0 errors)
Projects with sub-compositions: npx hyperframes snapshot --at <midpoints> and eyeball each frame
npx hyperframes preview for review (the user can edit anything in Studio's timeline)
npx hyperframes render only after the user approves
