hyperframes-cli

A command-line tool for creating, checking, previewing, and rendering HyperFrames HTML video compositions.

In plain words
What is it for?
Use it to start a video project, validate compositions, inspect them in headless Chrome, preview them, and render final video.
Why use it?
It catches structural and visual problems before rendering, such as missing identifiers, overlapping tracks, and text running outside its containers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hyperframes-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to hyperframes-cli — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HyperFrames CLI

Everything runs through npx hyperframes. Requires Node.js >= 22 and FFmpeg.

Workflow

  1. Scaffoldnpx hyperframes init my-video
  2. Write — author HTML composition (see the hyperframes skill)
  3. Lintnpx hyperframes lint
  4. Visual inspectnpx hyperframes inspect
  5. Previewnpx hyperframes preview
  6. Rendernpx hyperframes render

Lint and inspect before preview. lint catches missing data-composition-id, overlapping tracks, and unregistered timelines. inspect opens the rendered composition in headless Chrome, seeks through the timeline, and reports text spilling out of bubbles/containers or off the canvas.

Scaffolding

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 --example blank --tailwind # with Tailwind v4 browser runtime
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.

When using --tailwind, invoke the tailwind skill before editing classes or theme tokens. The scaffold uses Tailwind v4.2 via the browser runtime, not Studio's Tailwind v3 setup.

Linting

npx hyperframes lint                  # current directory
npx hyperframes lint ./my-project     # specific project
npx hyperframes lint --verbose        # info-level findings
npx hyperframes lint --json           # machine-readable

Lints index.html and all files in compositions/. Reports errors (must fix), warnings (should fix), and info (with --verbose).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
