hyperframes-cli is agent-read markdown (skill) from cowork-os/cowork-os: HyperFrames CLI tool — hyperframes init, lint, preview, render, transcribe, tts, doctor, browser, info, upgrade, compositions, docs, benchmark. Use when scaffolding a project, linting or validating compositions, previewing in the studio, rendering to video, transcribing audio, generating TTS, or troubleshooting the HyperFrames environment..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# HyperFrames CLI
Everything runs through `npx hyperframes`. Requires Node.js >= 22 and FFmpeg.
## Workflow
1. **Scaffold** — `npx hyperframes init my-video`
2. **Write** — author HTML composition (see the `hyperframes` skill)
3. **Lint** — `npx hyperframes lint`
4. **Preview** — `npx hyperframes preview`
5. **Render** — `npx hyperframes render`
Lint before preview — catches missing `data-composition-id`, overlapping tracks, unregistered timelines.
## Scaffolding
```bash
npx hyperframes init my-video # interactive wizard
npx hyperframes init my-video --example warm-grain # pick an example
npx hyperframes init my-video --video clip.mp4 # with video file
npx hyperframes init my-video --audio track.mp3 # with audio file
npx hyperframes init my-video --non-interactive # skip prompts (CI/agents)
```
Templates: `blank`, `warm-grain`, `play-mode`, `swiss-grid`, `vignelli`, `decision-tree`, `kinetic-type`, `product-promo`, `nyt-graph`.
`init` creates the right file structure, copies media, transcribes audio with Whisper, and installs AI coding skills. Use it instead of creating files by hand.
## Linting
```bash
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
