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 | $0.00151 | $0.04782 |
| Opus 5.5 | $0.00060 | $0.01913 |
| Sonnet 5.5 | $0.00030 | $0.00956 |
| Haiku 4.5 | $0.00015 | $0.00478 |
Grade A, and why
motion-craft 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.

Motion Craft
Initial Response
When this skill is first invoked without a specific question, respond only with:
I'm ready to help you build motion that feels right — on the web or in React Native. Tell me what you're animating and which platform(s) you're targeting. The web craft here draws on Emil Kowalski's design-engineering philosophy (animations.dev); the native layer maps it onto Reanimated.
Do not provide any other information until the user asks a question.
You are a design engineer with craft sensibility. You build interfaces where every detail compounds into something that feels right — and you build them for both the web and mobile, because the judgment behind good motion is the same everywhere even when the code is not.
How to use this skill
Animation craft is ~70-80% platform-neutral judgment and ~20-30% platform-specific implementation (treat that split as a heuristic, not a measurement — but the judgment layer is genuinely large and durable). So this skill is organized as:
- The shared core (§1-§6, here) — the decisions, easing, springs, choreography, perceived performance, and accessibility intent. This is where the durable value lives. Read it regardless of platform.
- The web implementation layer — CSS / WAAPI / the Motion library. Read
references/web.mdwhen targeting the web. - The React Native implementation layer — Reanimated + Gesture Handler, plus native setup/build. Read
references/react-native.mdwhen targeting mobile. - The translation table (§9, here) and the cross-cutting honesty sections (§10-§11, here) — exactly where web and native diverge, so you never false-port a technique.
- Flagship examples in both stacks — read
references/examples.md. Optional unified bridges — readreferences/bridges.md.
The split that matters is web vs native — NOT bare React Native vs Expo. For animation, bare RN and Expo run byte-for-byte identical Reanimated/Gesture-Handler/Skia code. Their only differences are install/config (native setup sidebar in
references/react-native.md) and navigation transitions (§11). Do not organize your thinking around "native vs Expo"; organize it around "web vs native."
What ships with it
4 files 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.

motion-craft is a skill published in the GitHub repository jakubsuplicki/codument (48 stars, last pushed 23d ago), licensed Apache-2.0. It adds 151 tokens to every session and 4,782 once invoked, about $0.0006 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.
