HyperFrames is an open-source framework that turns HTML, CSS, media, and timed animations into deterministic MP4 videos. It is used locally, by coding agents, and in hosted authoring workflows to create rendered videos from web-based designs. Its catalogue add-ons provide skills, agents, instructions, hooks, settings, and a plugin for agent-driven video production.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01827 | $0.01827 |
| Opus 5.5 | $0.00731 | $0.00731 |
| Sonnet 5.5 | $0.00365 | $0.00365 |
| Haiku 4.5 | $0.00183 | $0.00183 |
Grade A, and why
hyperframes AGENTS.md 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 13d 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.
How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hyperframes
Open-source video rendering framework: write HTML, render video.
Skills
This repo ships AI agent skills via vercel-labs/skills. Install them before writing compositions — they encode framework-specific patterns that generic docs don't cover. Default to the core set — the /hyperframes router installs each creation workflow on demand; install everything only when the user explicitly asks for the full set.
npx hyperframes skills update # default: installs/refreshes the core set — workflows install on demand
npx hyperframes skills # all 21 published skills at once
npx skills add heygen-com/hyperframes # interactive picker (terminal only; repo-internal skills are excluded by default)
Creation workflows route through one entry skill — read /hyperframes first: it orients you to the whole surface, confirms the brief up front (the intent layer), and maps "make me a…" intent — usually a video, but also a navigable deck (/slideshow) or a composition port (/remotion-to-hyperframes) — to a concrete workflow. Consult it before invoking a specific workflow:
/product-launch-video— any website URL (or a pre-written script / text brief in no-capture mode) → a product launch / promo video, or a site tour / showcase featuring the site's own captured screens; up to ~3 min (sweet spot ~30-90s)./faceless-explainer— arbitrary text, no URL and no website capture → faceless explainer, up to ~3 min (sweet spot ~30-90s); every visual is LLM-invented (typography / abstract graphics / diagram / data-viz)./embedded-captions— an existing talking-head video (MP4) → the same footage with captions / subtitles added (verbatim rail + embedded climax, or pure-cinematic embed); the footage itself is untouched (no NLE-style editing)./talking-head-recut— an existing talking-head / interview / podcast video (MP4) → the same footage packaged with designed graphic overlays (kinetic titles, lower-thirds, data callouts, pull-quotes, side panels, pip) synced to the transcript; the clip plays unchanged underneath, footage untouched. For plain captions/subtitles →/embedded-captions./pr-to-video— a GitHub PR (URL /owner/repo#N/ "this PR") → code-change explainer, up to ~3 min (changelog / feature reveal / fix / refactor). A PR link, not a product website./motion-graphics— a short (typically under 10s) design-led motion graphic, motion-is-the-message, no narration: kinetic type, a stat / number count-up, a chart, a logo sting, a lower-third / overlay, or an animated tweet / headline / captured-page highlight; rendered to MP4 or a transparent overlay. Longer / narrated / custom →/general-video./music-to-video— a music track (audio file, video to pull audio from, or one generated from a mood brief) → beat-synced video (lyric / slideshow / kinetic promo). Music drives pacing; user-supplied images / videos are cut onto the same beat grid./slideshow— a presentation / pitch deck / interactive deck — discrete slides, fragment reveals, branching, hotspot navigation, presenter mode. Output is a navigable deck, not a rendered video./general-video— fallback for any other video creation (title card, longer brand / sizzle reel, multi-scene montage, static loop, custom composition) and the home of companion mode — co-create with the full HyperFrames toolbox; the original hyperframes flow — design → plan → layout → build → validate, any length.
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.
