ux-copy

what it does

Write or review UX copy — microcopy, error messages, empty states, CTAs. Trigger with "write copy for", "what should this button say?", "review this error message", or when naming a CTA, wording a confirmation dialog, filling an empty state, or writing onboarding text.

Same request, same model, once with the skill and once without. Read both and judge for yourself.

“Rewrite this confirmation dialog. It shows when someone deletes a workspace.”

Source material given with the request

Current dialog: Title: Are you sure? Body: This action cannot be reversed. Buttons: [OK] [Cancel] Facts: the workspace "Northwind Ops" has 14 projects and 6 members. Deleting it removes all projects and files for everyone, permanently. Only owners can delete.

with the skill

## UX Copy: Delete workspace ### Recommended Copy **Title:** Delete “Northwind Ops”? **Body:** This workspace has 14 projects and 6 members. Deleting it will permanently delete all its projects and files for everyone. This can’t be undone. **Destructive button:** Delete workspace **Secondary button:** Keep workspace ### Rationale Names the workspace, makes the impact on everyone explicit, and replaces generic buttons with clear actions. Keep deletion available only to owners; the dialog doesn’t need to repeat that permission rule. ### Localization Notes Treat “Northwind Ops” as a workspace name, not translatable text. Support plural forms for project and member counts.
