/copy — Master UI Copywriting

Audits every word the user sees and rewrites it to be clear, specific, and benefit-first. Works screen by screen, from highest to lowest priority, verifying every change visually before advancing.

Before starting: read ~/.claude/skills/ui-design-principles/SKILL.md — writing rules (expose benefit not action, strongest statement first, $1000 per deleted word) are in there and apply throughout.
