Ux Copy

anthropics/knowledge-work-pluginsOfficial

This does the tedious work of writing interface microcopy: button labels, error messages, empty states, confirmation dialogs, all the little text that makes or breaks user experience. It follows solid UX writing principles (clear, concise, human) and gives you structured output with a main recommendation plus alternatives in a comparison table. The guidance is practical, like structuring error messages as "what happened + why + how to fix" or making CTAs start with verbs. If you have design tools or a knowledge base connected, it can pull brand voice guidelines and check actual layout constraints. Honestly, this is most useful when you're stuck on how to phrase something or need to quickly generate options that don't sound robotic.

If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md.

Write or review UX copy for any interface context.

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

Output

## UX Copy: [Context]

### Recommended Copy
**[Element]**: [Copy]

### Alternatives
| Option | Copy | Tone | Best For |
|--------|------|------|----------|
| A | [Copy] | [Tone] | [When to use] |
| B | [Copy] | [Tone] | [When to use] |
| 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]

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.
