Write and review UX copy—buttons, error messages, empty states, and onboarding text.

What is ux-copy?

A skill for crafting or evaluating user-facing copy across interface elements. Use it when naming CTAs, wording error messages, filling empty states, writing confirmation dialogs, or creating onboarding text. Applies copywriting principles (clarity, conciseness, consistency, usefulness, humanity) to match your brand voice and user context.

  • Generate copy for CTAs, error messages, empty states, confirmation dialogs, tooltips, and loading states
  • Provide multiple copy options with tone and use-case guidance
  • Apply structured patterns: error messages (what + why + fix), empty states (what + why + start), confirmations (action clarity + consequences)
  • Adapt tone to context—celebratory for success, empathetic for errors, clear for warnings
  • Pull brand voice guidelines and content standards if knowledge base is connected
  • View design context and character limits if design tool is connected

ux-copy FAQ

What information should I provide for best results?

Be specific about context (e.g., 'Error message when payment fails' not just 'error message'), share your brand voice ('professional but warm'), and consider the user's emotional state. Include character limits or platform constraints if relevant.

Does it work with design tools?

Yes—if a design tool connector is available, it can view your Figma screen to understand the full user flow and check character limits and layout constraints.

Can it match my brand voice?

Yes. Share your brand voice guidelines and content style guide, and it will adapt tone and terminology accordingly. If a knowledge base is connected, it can pull these automatically.

What copy patterns does it cover?

CTAs (verb-first, specific), error messages (what + why + fix), empty states (what + why + start), confirmation dialogs (action clarity + consequences), tooltips, loading states, and onboarding text.

Does it provide alternatives?

Yes. It generates multiple copy options with tone and use-case guidance in a comparison table, so you can choose what fits best.

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

  1. Clear: Say exactly what you mean. No jargon, no ambiguity.
  2. Concise: Use the fewest words that convey the full meaning.
  3. Consistent: Same terms for the same things everywhere.
  4. Useful: Every word should help the user accomplish their goal.
  5. 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

If Connectors Available

If ~~knowledge base is connected:

  • Pull your brand voice guidelines and content style guide
  • Check for existing copy patterns and terminology standards

If ~~design tool is connected:

  • View the screen context in Figma to understand the full user flow
  • Check character limits and layout constraints from the design

Tips

  1. Be specific about context — "Error message when payment fails" is better than "error message."
  2. Share your brand voice — "We're professional but warm" helps me match your tone.
  3. Consider the user's emotional state — Error messages need empathy. Success messages can celebrate.
