Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00187 | $0.01921 |
| Opus 5.5 | $0.00075 | $0.00768 |
| Sonnet 5.5 | $0.00037 | $0.00384 |
| Haiku 4.5 | $0.00019 | $0.00192 |
Grade A, and why
motion-studio 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 22d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Motion studio
Every video here is a program. Claude writes code that paints a frame for any moment in time, a headless browser (or Node canvas) captures the frames, ffmpeg encodes them. The model cannot emit an MP4; only an agent with a shell can render, listen to and look at its own frames. The prompt is 10 percent of the video; the harness (renderer, sound, critique loop) is the other 90.
When to use
- Launch videos, product reels, showreels, motion ads, UI morph loops, music videos, explainers, short films made in code.
- Turning a product URL, a reference clip or a song into a rendered MP4.
- Building or fixing the pipeline itself:
seek(t), springs, beat grid, SFX, critique loop.
Pick a route first
| Route | When | Read |
|---|---|---|
A. Canvas seek(t) + Playwright + ffmpeg (default) |
Any one-off film; zero dependencies, full control | references/render-engine.md |
| A1. Clawd / p5.brush cartoon | Animations starring the Claude mascot, painted storybook cartoons | references/clawd-mascot.md |
| A2. Hand-drawn Node canvas (no browser) | Storybook, brush-ink and watercolour, low-poly loops, game-feel shorts | references/hand-drawn-canvas.md |
| B. HyperFrames (HTML + GSAP, agent skills) | Web-page thinking, captions, voiceover, templates, Studio editing | references/hyperframes.md |
| C. Remotion (React) | Teams already in React, series, data-driven templates | references/remotion.md |
Opus defaults to route A (one index.html, Playwright, ffmpeg, zero dependencies) and skips Remotion and HyperFrames even when installed. If the user wants a framework, say so explicitly in the brief.
HyperFrames setup (ask the user first; needs Node.js: fnm install --lts or brew install node): run npx skills add heygen-com/hyperframes and choose Core Skills; for CI or non-interactive refresh run npx hyperframes skills update. Start a fresh chat afterwards and ask it to use /hyperframes. HyperFrames needs no React or build step and is Apache 2.0; Remotion fits teams already writing React (components, design system, typed inputs).
What ships with it

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.

motion-studio is a skill published in the GitHub repository mgiovani/cc-arsenal (8 stars, last pushed 2d ago), licensed MIT. It adds 187 tokens to every session and 1,921 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-02.
