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 | $0.00066 | $0.02918 |
| Opus 5 | $0.00033 | $0.01459 |
| Sonnet 5 | $0.00013 | $0.00584 |
| Haiku 4.5 | $0.00007 | $0.00292 |
Grade A, and why
ux-copy 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 11d 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 — 237 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UX Copy — UI Text That Works
Production-ready UX copy patterns for React and Next.js applications. Every pattern includes real JSX examples — not just advice, but copy you can use directly in components.
This skill works in two modes:
- Greenfield — establishing voice, writing first copy, setting up copy architecture
- Mature codebase — auditing existing copy, fixing inconsistencies, refactoring for clarity
Architecture Overview
[Voice Definition]
├── Voice worksheet (4 dimensions: formality, humor, authority, warmth)
├── Tone spectrum map (which contexts allow flexibility)
└── Project voice profile ("confident, precise, reassuring")
↓
[Component Copy Rules]
├── Buttons → verb-first, specific action, 2-4 words
├── Errors → what happened + why + what to do
├── Empty states → explain + guide + single CTA
├── Confirmations → name the action, never Yes/No
├── Notifications → severity determines tone and persistence
├── Labels → describe the field, not the format
└── Tooltips → one sentence, answers "what is this?"
↓
[Writing]
├── Apply universal rules (plain language, active voice, front-load)
├── Modulate tone to context (errors serious, onboarding flexible)
└── Match existing voice if mature codebase
↓
[Review]
├── 3 C's test: Clear → Concise → Character
├── Read aloud test
└── Consistency check (1 entity = 1 term)

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.

ux-copy is a skill published in the GitHub repository LeahyCC/claude-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 66 tokens to every session and 2,918 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 2026-08-31.
