hyperframes-core SKILL.md skillB

Removed from GitHub on 2026-10-23. The file no longer exists in its repository, and every version below is still saved here. mdr add no longer finds it by name, but a lockfile that pins one of these versions still installs it from its recorded commit, for as long as GitHub keeps that commit.

hyperframes-core from heygen-com/hyperframes is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

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.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

**Plugin installs:** Before setup or freshness commands, follow [plugin execution rules](../hyperframes/references/plugin-installation.md) when this skill is inside a HyperFrames plugin. Standalone installs keep the update instructions below.

# HyperFrames Core

**Agent pitfalls (read first):**

- Center with flex/`inset`, not CSS `transform: translate(-50%,-50%)` on a node you then GSAP `x`/`y`. Lint: `gsap_css_transform_conflict`. Use `fromTo` or `xPercent`/`yPercent`.
- Do not add a scene-exit `tl.set(..., {visibility:"hidden"})`. The runtime already hides timed clips. Opacity fades on inner nodes (or `opacity` on `.clip`) are enough. Caption hard-kills are a different rule.
- `window.__timelines["id"]` must match the root `data-composition-id`.
- After `render`, read the summary's second line: `beginframe` vs `screenshot`, GPU mode, stage timings. `screenshot` + `software gpu` on Linux is the slow path.

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.

How to install

The exact contents, by fingerprint

The line at the top of this page is already the fingerprint pin, because a file GitHub no longer serves cannot be found by its label. With it the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
