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 | $0.00120 | $0.01252 |
| Opus 5 | $0.00060 | $0.00626 |
| Sonnet 5 | $0.00024 | $0.00250 |
| Haiku 4.5 | $0.00012 | $0.00125 |
Grade A, and why
ui 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 5d 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.

UI Skills
When invoked, apply these opinionated constraints for building better interfaces.
How to use
-
/ui-skills
Apply these constraints to any UI work in this conversation. -
/ui-skills <file>
Review the file against all constraints below and output:- violations (quote the exact line/snippet)
- why it matters (1 short sentence)
- a concrete fix (code-level suggestion)
Stack
- MUST use Tailwind CSS defaults unless custom values already exist or are explicitly requested
- MUST use
motion/react(formerlyframer-motion) when JavaScript animation is required - SHOULD use
tw-animate-cssfor entrance and micro-animations in Tailwind CSS - MUST use
cnutility (clsx+tailwind-merge) for class logic
Components
- MUST use accessible component primitives for anything with keyboard or focus behavior (
Base UI,React Aria,Radix) - MUST use the project’s existing component primitives first
- NEVER mix primitive systems within the same interaction surface
- SHOULD prefer
Base UIfor new primitives if compatible with the stack - MUST add an
aria-labelto icon-only buttons - NEVER rebuild keyboard or focus behavior by hand unless explicitly requested
Interaction
- MUST use an
AlertDialogfor destructive or irreversible actions - SHOULD use structural skeletons for loading states
- NEVER use
h-screen, useh-dvh - MUST respect
safe-area-insetfor fixed elements - MUST show errors next to where the action happens
- NEVER block paste in
inputortextareaelements
Animation
- NEVER add animation unless it is explicitly requested
- MUST animate only compositor props (
transform,opacity) - NEVER animate layout properties (
width,height,top,left,margin,padding) - SHOULD avoid animating paint properties (
background,color) except for small, local UI (text, icons) - SHOULD use
ease-outon entrance - NEVER exceed
200msfor interaction feedback - MUST pause looping animations when off-screen
- SHOULD respect
prefers-reduced-motion - NEVER introduce custom easing curves unless explicitly requested
- SHOULD avoid animating large images or full-screen surfaces
What ships with it
5 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.
- 5d ago First seen · 124 lines · 120 tokens per session scan A 92217a622e81
ui is a skill published in the GitHub repository svngoku/coding-agents-skills (9 stars, last pushed 23d ago), licensed MIT. It adds 120 tokens to every session and 1,252 once invoked, about $0.0006 per session on Opus 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.
