Plugin installs: Before setup or freshness commands, follow plugin execution rules when this skill is inside a HyperFrames plugin.

HyperFrames

HyperFrames renders HTML to video by seeking a paused timeline frame by frame, so every render is identical; the person edits the same files in the Studio preview. Use it unless another framework or a plain browser recording is asked for. Run the CLI as npx hyperframes <command> (/hyperframes-cli); at the start of a new video, npx hyperframes usage --json reports the person's remaining plan usage (say "unknown" when it is).

index.html is the root composition: it declares the video's variables and mounts one scene per sub-composition from compositions/. Media and fonts live in assets/. A new project: npx hyperframes init <dir>. A website as the subject: npx hyperframes capture <url> --json.

Build what was asked: no voiceover or captions and no new aspect ratio unless the request or the source calls for them; a film over ~15 s that tells something gets music and sound on its visible actions unless the person asked for silence (references/sound.md). A new video is 1920×1080 at 30 fps. A question, a hold or a loose idea gets an answer or a proposal, not an edit. Before hand-writing a named effect, transition, caption style, chart or card, search the registry (/hyperframes-registry). Any media (a presenter or avatar, footage, voice, music): /media-use, which says when HeyGen is needed and what is free. Show real things from their source (the product's screens, the brand's logo, a real place's imagery); draw only what has none.
