hyperframes-core SKILL.md skillB

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

Install it, pinned

mdr add coco-research/coco/hyperframes-core@git:20260731.f9cd29e

Pins git:20260731.f9cd29e in mdr.lock. Pin the fingerprint instead.

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.

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

# 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.

How to install

The exact contents, by fingerprint

mdr add coco-research/coco/hyperframes-core@sha256:4b710ea43ded2135

The line at the top of this page pins the label git:20260731.f9cd29e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way 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.
