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 | $0.00052 | $0.03537 |
| Opus 5 | $0.00026 | $0.01768 |
| Sonnet 5 | $0.00010 | $0.00707 |
| Haiku 4.5 | $0.00005 | $0.00354 |
Grade A, and why
userinterface-wiki 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 3d 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.

User Interface Wiki
Comprehensive UI/UX best practices guide for web interfaces. Contains 152 rules across 12 categories, prioritized by impact to guide automated code review and generation.
When to Apply
Reference these guidelines when:
- Implementing or reviewing animations (CSS transitions, Motion/Framer Motion)
- Choosing between springs, easing curves, or no animation
- Working with AnimatePresence and exit animations
- Writing CSS with pseudo-elements or View Transitions API
- Adding audio feedback or procedural sound to UI
- Building morphing icon components
- Animating container width/height with dynamic content
- Designing UI that respects cognitive psychology (Fitts's, Hick's, Miller's laws)
- Implementing predictive prefetching for perceived performance
- Setting up typography, OpenType features, or numeric formatting

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.
- 3d ago First seen · 254 lines · 52 tokens per session scan A 663ccc340e7e
userinterface-wiki is a skill published in the GitHub repository raphaelsalaja/userinterface-wiki (884 stars, last pushed 1mo ago), licensed MIT. It adds 52 tokens to every session and 3,537 once invoked, about $0.0003 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 2026-08-30.
