The HyperFrames composition contract — build one renderable project.

  • Composition structure
  • SKILL.md covers References, Building a composition, Editing existing compositions and Validation
  • Calls npx
  • The data- timing attributes

What it does

Hyperframes Core is an agent skill from chmonitor/chmonitor. 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. Read before writing composition HTML.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including reference files (for example `references/composition-patterns.md`, `references/data-attributes.md` and `references/determinism-rules.md`).

It sits in Media & Creative, covering Motion graphics. It works with HeyGen. The repository describes itself as: Open-source operational advisor for ClickHouse — real-time monitoring plus AI-driven index/partition/materialized-view recommendations. The licence is GPL-3.0.

When your agent uses it

  • Composition structure
  • The data- timing attributes
  • Sub-compositions
  • Framework-owned media playback

Example prompts

  • “/hyperframes-core”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit fc39ef0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Hyperframes Core loads about 1.7k tokens when it runs, and up to ~20k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 679 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~20k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
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. Read before writing composition HTML.

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, hyperframes-media, hyperframes-cli, hyperframes-registry. The capability map in /hyperframes says what each one covers.

references/tailwind.mdwork 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.
  • 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
