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 | $0.00062 | $0.00830 |
| Opus 5 | $0.00031 | $0.00415 |
| Sonnet 5 | $0.00012 | $0.00166 |
| Haiku 4.5 | $0.00006 | $0.00083 |
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 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.

Usage
/ux-copy $ARGUMENTS
What I Need From You
- Context: What screen, flow, or feature?
- User state: What is the user trying to do? How are they feeling?
- Tone: Formal, friendly, playful, reassuring?
- Constraints: Character limits, platform guidelines?
Principles
- Clear: Say exactly what you mean. No jargon, no ambiguity.
- Concise: Use the fewest words that convey the full meaning.
- Consistent: Same terms for the same things everywhere.
- Useful: Every word should help the user accomplish their goal.
- Human: Write like a helpful person, not a robot.
Copy Patterns
CTAs
- Start with a verb: "Start free trial", "Save changes", "Download report"
- Be specific: "Create account" not "Submit"
- Match the outcome to the label
Error Messages
Structure: What happened + Why + How to fix
- "Payment declined. Your card was declined by your bank. Try a different card or contact your bank."
Empty States
Structure: What this is + Why it's empty + How to start
- "No projects yet. Create your first project to start collaborating with your team."
Confirmation Dialogs
- Make the action clear: "Delete 3 files?" not "Are you sure?"
- Describe consequences: "This can't be undone"
- Label buttons with the action: "Delete files" / "Keep files" not "OK" / "Cancel"
Tooltips
- Concise, helpful, never obvious
Loading States
- Set expectations, reduce anxiety
Onboarding
- Progressive disclosure, one concept at a time
Voice and Tone
Adapt tone to context:
- Success: Celebratory but not over the top
- Error: Empathetic and helpful
- Warning: Clear and actionable
- Neutral: Informative and concise
Output
## UX Copy: [Context]
### Recommended Copy
**[Element]**: [Copy]
### Alternatives

| C | [Copy] | [Tone] | [When to use] |
### Rationale
[Why this copy works — user context, clarity, action-orientation]
### Localization Notes
[Anything translators should know — idioms to avoid, character expansion, cultural context]
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 · 108 lines · 62 tokens per session scan A d46a00a62ec6
ux-copy is a skill published in the GitHub repository anthropics/knowledge-work-plugins (23,791 stars, last pushed yesterday), licensed Apache-2.0. It adds 62 tokens to every session and 830 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.
