What it does

UX Writing is an agent skill from plugin87/ux-ui-agent-skills. 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.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design. The repository describes itself as: Turn Claude into a senior design architect: DTCG tokens, 52 components, WCAG 2.2 AA-AAA, 138 design systems, any-framework code, and 50 objective gates that fail the build… The licence is MIT.

When your agent uses it

  • The user needs interface copy
  • Empty-state text

Example prompts

  • “/ux-writing”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Read ${CLAUDE_SKILL_DIR}/../../../content/voice-tone.md (voice principles, tone spectrum, formulas, microcopy patterns, inclusive…
  2. Match tone to the user's emotional state (onboarding/success/routine/error/destructive). Higher stress → plainer language.
  3. Apply the formulas
  4. Enforce mechanics: sentence case, no ALL CAPS, numerals, no blame on the user, labels (not placeholders), no directional/color-only…
  5. Run the 10-item pre-ship copy checklist.

What it can do on your machine

Read from SKILL.md and the folder at commit 14f8d44. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

UX Writing loads about 658 tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 281 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~83
When it runs · the whole SKILL.md, loaded when a task matches
~658

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
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.

Skill: UX Writing

Step 0 — is the kit here? This skill reads files from the kit. Check once: ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING On KIT_MISSING only the skill folders were installed, which is what npx skills add does. Say so plainly, point the user at npx ux-ui-agent-skills init or the plugin install, and stop. Do not guess the contents of a file you could not open.

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).
