What is write-ux-copy?

A writing tool for the words people see in software interfaces, including buttons, labels, errors, tooltips, notifications, onboarding screens, and empty states.

Use it to create or review copy for interface features, forms, error messages, confirmations, help text, and onboarding flows.

It helps replace unclear or unhelpful interface text with wording that guides users through actions and problems.

Token cost

What it costs to keep this loaded

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	$0.00087	$0.01345
Opus 5	$0.00044	$0.00673
Sonnet 5	$0.00017	$0.00269
Haiku 4.5	$0.00009	$0.00135

Security

Grade A, and why

write-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 10d 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.

"Review this copy for clarity and tone"
"Create microcopy for [UI element]"
"Write onboarding copy for [feature]"
"Create notification copy for [event]"

Core Workflows

1. Create UI Copy for Feature

When to use: Generating complete UI copy set for new features or flows

Process:

Understand the feature
- Review feature spec or brief if available
- Identify all UI elements needing copy
- Understand user flows and interactions
- Note technical constraints (character limits, etc.)
Generate copy elements
- Button labels (primary, secondary, destructive actions)
- Form labels and placeholders
- Error messages and validation text
- Success messages and confirmations
- Tooltips and help text
- Page titles and headings
- Navigation labels
- Empty states
- Loading states
Organize by context
- Group by user flow or screen
- Include context notes for developers
- Provide character length limits if needed
- Note dynamic content placeholders

Output format:

Organize as table or grouped list:

## Login Screen

| Element | Copy | Notes |
|---------|------|-------|
| Heading | Sign in to your account | |
| Email field label | Email address | |
| Email placeholder | [email protected] | Show example format |
| Password field label | Password | |
| Primary button | Sign in | Action-oriented |
| Secondary link | Create account | |
| Forgot password link | Forgot password? | |
| Error (invalid email) | Please enter a valid email address | Specific and helpful |
| Error (wrong credentials) | Email or password is incorrect | Don't specify which for security |
| Success message | Welcome back! | Friendly confirmation |

Files

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.

Changes

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.
