What UX Copy does
The UX Copy skill is designed to assist developers and designers in creating and reviewing user experience copy across various interface contexts. This skill can be triggered with phrases like "write copy for" or "what should this button say?" and is particularly useful for generating microcopy, error messages, empty states, and call-to-action (CTA) text. By providing specific context, user state, tone, and constraints, users can receive tailored copy suggestions that enhance the overall user experience.
The skill operates on several principles that ensure the output is clear, concise, consistent, useful, and human-like. This means avoiding jargon and ambiguity while using the fewest words necessary to convey meaning. The skill emphasizes the importance of matching the tone to the context, whether it's celebratory for success messages or empathetic for error messages. By following these guidelines, the skill helps users communicate effectively with their audience.
Additionally, the UX Copy skill provides structured patterns for various types of copy, including CTAs, error messages, empty states, confirmation dialogs, tooltips, loading states, and onboarding text. Each pattern comes with specific recommendations on structure and wording to optimize clarity and user engagement. For example, CTAs should begin with a verb and be specific about the action, while error messages should clearly explain what happened, why, and how the user can resolve the issue.
This skill is ideal for UX writers, product designers, and developers who need assistance in creating user-friendly copy that aligns with their design and branding guidelines. By leveraging this skill, users can ensure their interface copy is not only functional but also enhances the user's journey through the application.

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
