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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00127 | $0.01890 |
| Opus 5.5 | $0.00051 | $0.00756 |
| Sonnet 5.5 | $0.00025 | $0.00378 |
| Haiku 4.5 | $0.00013 | $0.00189 |
Grade A, and why
p5-paint-animation 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 1mo 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 — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
p5 Paint Animation
Three flows, one engine. Pick by input:
| Input | Flow | Output |
|---|---|---|
| Text prompt / phrase | A: Write-on | Handwriting animates onto ruled paper, pen-tracked for camera |
| Photo | B: Repaint + paint-on | Brushstroke painting, still or painting-itself film, camera pull |
| Video / Live Photo | C: Living painting | Every frame repainted over a locked stroke lattice |
When to use / when not
Use for: hand-made-looking motion — handwriting that writes itself, photos as brushstroke paintings (still or animating), short clips as living paintings. Do NOT use for: crisp typography or brand-accurate text (use real fonts), photoreal output, footage longer than ~10s (render cost scales per frame ≈ 5–20s each), or live/interactive pages (this renders offline MP4/PNG).
Requirements and side effects
- Requires: Node 22.12+, ffmpeg on PATH, ~500MB disk (Chromium).
sh scripts/setup.sh(run manually, once) uses the committed lockfile to download pinned dependencies from the npm registry: puppeteer 25.9.0, p5 2.3.2 (LGPL-2.1), and p5.brush 2.2.1 (MIT). Puppeteer downloads its pinned Chrome for Testing build from Google's download service. Read-only downloads; no credentials, no cost, nothing uploaded.- Renders launch sandboxed headless Chromium on a blank page. Network and local file requests from sketches are blocked; sketches receive inputs as data URLs.
- Writes only inside paths you pass (
out.png/out.mp4, plus a sibling.track.jsonand, with--keep-frames 1, a_frames_*directory). - Optional, only for flow C subject matting:
npx hyperframes remove-background(downloads the HyperFrames CLI from npm; local CoreML inference, no data leaves the machine).
Verify success
Render any command below, then open the output: the last frame must show the
complete artwork (text fully written / painting fully covered), and re-running
with the same --seed must produce identical bytes on the canvas. The smoke
test used for review: node render-anim.mjs sketches/handwriting.anim.js /tmp/t.mp4 --size 1600x900 --seed 7 --inject 'PHRASE="go make something"'.

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.

p5-paint-animation is a skill published in the GitHub repository heygen-com/hyperframes-community-skills (229 stars, last pushed 5d ago), licensed Apache-2.0. It adds 127 tokens to every session and 1,890 once invoked, about $0.0005 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 2026-08-30.
