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 | $0.00036 | $0.01766 |
| Opus 5.5 | $0.00014 | $0.00706 |
| Sonnet 5.5 | $0.00007 | $0.00353 |
| Haiku 4.5 | $0.00004 | $0.00177 |
Grade A, and why
pn-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 — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Animation skill
This SKILL.md is a router; load reference.md only when that workflow is active.
When to use
- Designing a motion system for a new project (motion tokens, duration scale, easing library).
- Auditing existing animations against the motion role taxonomy and
prefers-reduced-motionrequirements. - Choosing between GSAP, Motion, and CSS for a given animation context.
- Implementing any intentional UI animation: staggered reveals, scroll-triggered sequences, hover effects, page/route transitions, micro-interactions, or loading/success states.
Every animation must carry a motion role (Reveal / Orient / Confirm / Delight). If it fits none, remove it. This is non-negotiable per pn-frontend-design-philosophy.
For full GSAP API — timelines, easing, ScrollTrigger, plugins, framework integrations, and video Frame Adapter — load pn-gsap. For CSS and Motion (React) code patterns, see reference.md.
Library selection guide
| Context | Library | Why |
|---|---|---|
| React declarative animation, layout transitions, gestures | Motion (Framer Motion successor) | Co-located with JSX; handles layout with layout prop; drag/gesture support |
| Timeline control, complex scroll sequences, staggered choreography, vanilla JS | GSAP + ScrollTrigger | Best-in-class timeline API; frame-accurate scroll-trigger; works without framework → see pn-gsap |
| Simple single-property transitions, hover states, focus states | CSS transitions | Zero JS overhead; browser-native; always prefer for simple cases |
| Looping illustrations, icon micro-animations | CSS keyframes or Lottie | CSS for geometric; Lottie for designer-authored complex illustration loops |
| React + complex scroll sequences | GSAP inside useGSAP | useGSAP hook handles React lifecycle and cleanup automatically → see pn-gsap |
Install:
npm install motion # Motion (React)
npm install gsap # GSAP (ScrollTrigger included)
npm install @gsap/react # useGSAP hook
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

pn-animation is a skill published in the GitHub repository perniemann/pnCore (0 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 1,766 once invoked, about $0.0001 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 2026-09-03.
