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 | $0.00070 | $0.06329 |
| Opus 5.5 | $0.00028 | $0.02532 |
| Sonnet 5.5 | $0.00014 | $0.01266 |
| Haiku 4.5 | $0.00007 | $0.00633 |
Grade A, and why
webkit-motion-polish 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.

Skill: webkit-motion-polish
Purpose
Apply motion that feels native to the design system: token-driven, fast, accessible, and limited to properties the compositor can animate cheaply. Motion should confirm an action or guide attention — never decorate.
How to use
/webkit-motion-polishApply the motion constraints below to any animated UI in this conversation./webkit-motion-polish <file>Review the file's animations and output, per violation:- the exact line / snippet (quoted),
- why it's wrong (1 short sentence),
- the token-based fix.
How to find the tokens
Never guess a duration, curve, or utility name. Resolve them the same way every time:
- Ask the webkit MCP — it lists the
animate-*utilities and theduration-*/ease-*/curvetokens that ship in@aziontech/theme. - If a utility or token name is not one the MCP lists, it does not exist — do not invent a
duration-[…]or an inlinecubic-bezier.
When to invoke
- After structure (
webkit-ux-heuristics) and baseline (webkit-baseline-ui) are sound. - Adding entrances/exits, hover/active feedback, or overlay open/close motion.
- The user asks to "make it smooth", "add a transition", "animate this".
Constraints
Use only the catalogued utilities
The animate-* utilities from the animation token catalog (listed by the webkit MCP) — they ship with
motion-safe / motion-reduce variants:
| Utility | Behavior |
|---|---|
animate-fade-in / animate-fade-out |
opacity in / out |
animate-slide-down |
height 0 → auto (the one catalogued height animation — see note) |
animate-popup-scale-in / animate-popup-scale-out |
scale + fade for popovers/menus |
animate-slide-in-left / animate-slide-out-left |
left-anchored panel enter/leave (sidebar, nav drawer) |
animate-slide-in-right / animate-slide-out-right |
right-anchored panel enter/leave (settings/detail drawer) |
animate-blink |
caret/blink |
animate-highlight-fade |
row-flash highlight |
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.

webkit-motion-polish is a skill published in the GitHub repository aziontech/webkit (3 stars, last pushed today), licensed MIT. It adds 70 tokens to every session and 6,329 once invoked, about $0.0003 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 2026-08-31.
