Install UX Writing
Pick your agent. Every command is ready to paste.
npx skills add plugin87/ux-ui-agent-skills --skill ux-writingThe open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.
01
Install it
Run the command above, or upload the folder in Claude.
02
Ask naturally
Describe the task. Your agent loads ux-writing when the request matches its description.
03
Name it if needed
If it does not trigger, say “use the ux-writing skill”. In Codex, type $ux-writing.
The skill itself
SKILL.md
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_MISSINGOnKIT_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 lineSkipped (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
- Read
${CLAUDE_SKILL_DIR}/../../../content/voice-tone.md(voice principles, tone spectrum, formulas, microcopy patterns, inclusive language, pre-ship checklist). - Match tone to the user's emotional state (onboarding/success/routine/error/destructive). Higher stress → plainer language.
- 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.
- Enforce mechanics: sentence case, no ALL CAPS, numerals, no blame on the user, labels (not placeholders), no directional/color-only instructions.
- 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).
Tips for UX Writing
- • Start a fresh session after installing so your agent picks up the new skill.
- • It is part of a pack with 26 skills. Install only the ones you need with --skill to keep triggers precise.
- • If two skills overlap, mention the one you want by name.
Questions about UX Writing
What does the UX Writing skill do?
Write or review UI copy (buttons, errors, empty states, microcopy, notifications, labels) using the voice & tone system (clear, concise, useful, human, honest) with the what→why→how error formula and inclusive-language rules. Use when the user needs interface copy, error messages, empty-state text, or a copy review.
