# Skill: UX Writing

## Requirements

This skill needs the full UX/UI Agent Skills kit: the gates, the references and
the design-system library. Install it with `npx ux-ui-agent-skills@3.1.0 init`
or as the Claude Code plugin. `npx skills@1.7.6 add` copies the skill folder and
nothing else. Installed that way, this skill runs in **guidance-only mode**: no gate
runs, so it gives no verdict.

> **Step 0: is the kit here?** Check once:
> `ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING`
> On `KIT_MISSING`, open your reply with: "Guidance-only mode: the UX/UI Agent
> Skills kit is not installed here, so no gate ran and nothing below is
> measured." Then work from this file and general practice, under three rules.
> Do not guess or cite the contents of a kit file you could not open. State no
> measured number (no contrast ratio, no N/N, no "passes WCAG"): write "not
> verified" where one would go. End with a line `Skipped (kit not installed):`
> that names every gate script this file tells you to run, then the install
> command above.

Produce or critique interface copy in the project's voice.

## Steps
1. Read `${CLAUDE_SKILL_DIR}/../../../content/voice-tone.md` (voice principles, tone spectrum, formulas, microcopy patterns, inclusive language, pre-ship checklist).
2. Match tone to the user's emotional state (onboarding/success/routine/error/destructive). Higher stress → plainer language.
3. Apply the formulas:
   - Buttons: frontload the verb, name the outcome.
   - **Confirmation dialogs:** the confirm button **restates the action and object**: "Delete account", not "Delete"/"OK"/"Yes"/"Confirm". The title asks ("Delete account?"), the button answers in matching words. Cancel stays "Cancel". For irreversible/high-stakes actions, require a **type-to-confirm** step (WCAG 3.3.4/3.3.6).
   - Errors: what happened → why → how to fix (no dead ends, no codes/stack traces).
   - Empty states: value → first action.
4. Enforce mechanics: sentence case, no ALL CAPS, numerals, no blame on the user, labels (not placeholders), no directional/color-only instructions.
5. Run the 10-item pre-ship copy checklist.

## Output
Final copy (or a redline review) that reads naturally aloud and passes the checklist. Keep within any character limits for tight UI.

## Verification (mandatory before declaring done)
Run every line through the 10-item pre-ship checklist in `${CLAUDE_SKILL_DIR}/../../../content/voice-tone.md`. Do not skip it:
- Reads naturally **aloud**; frontloaded verb on actions; no jargon/blame/dead-ends.
- Errors follow what→why→how; empty states give value→action; no bare "No data"/"Error".
- Mechanics: sentence case, numerals, labels (not placeholders), no color/direction-only cues, inclusive language.
- Within character limits; translatable (no concatenation; see `${CLAUDE_SKILL_DIR}/../../../accessibility/i18n-rtl.md`).
