## What it does

The skill handles wording shown directly to users inside software, including modals, alerts, and CLI outputs. It strictly sets boundaries: do not invoke it for marketing copy, blog posts, or API documentation.

Its workflow begins by checking `CLAUDE.md`, `AGENTS.md`, or style guides for voice definitions. If none exist, it walks through questions regarding audience and personality traits before consulting `references/patterns.md`.

Edits follow an explicit hierarchy. Clarity always overrides voice, and voice overrides stylistic craft rules. Every proposed revision presents the original copy alongside the rewrite and an explanation tied to the product tone.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add andrewgleave/skills --skill writing-for-interfaces -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/writing-for-interfaces/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/writing-for-interfaces/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add andrewgleave/skills --skill writing-for-interfaces -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/writing-for-interfaces/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add andrewgleave/skills --skill writing-for-interfaces -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/writing-for-interfaces/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install andrewgleave/skills writing-for-interfaces
```

2. **Manually: put the files in place**
- File: `.github/skills/writing-for-interfaces/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add andrewgleave/skills --skill writing-for-interfaces -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/andrewgleave/skills --path writing-for-interfaces
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/writing-for-interfaces/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add andrewgleave/skills --skill writing-for-interfaces -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/andrewgleave/skills/tree/HEAD/writing-for-interfaces/SKILL.md

## When to use it
- rewrite cryptic error messages into clear steps
- refine button labels and confirmation dialogs
- draft onboarding screens and empty states
- standardize wording across CLI outputs
- establish a durable product voice definition

## Example prompts
- Rewrite this network error message so users know what to do next
- Review the UX copy across this checkout modal flow
- Improve this CLI tool output message for failed authentication

BEGIN THIRD-PARTY FILE 0d19eee1ecb4a871
```text

name: writing-for-interfaces
description: >
  Use when someone asks to write, rewrite, review, or improve text that appears inside a
  product or interface. Examples: "review the UX copy", "is there a better way to phrase
  this", "rewrite this error message", "write copy for this screen/flow/page", reviewing
  button labels, improving CLI output messages, writing onboarding copy, settings
  descriptions, or confirmation dialogs. Trigger whenever the request involves wording shown
  to end users inside software — apps, web, CLI, email notifications, modals, tooltips,
  empty states, or alerts. Also trigger for vague requests like "review the UX" where
  interface copy review is implied. Do NOT trigger for content marketing, blog posts, app
  store listings, API docs, brand guides, cover letters, or interview questions — this is a
  technical writing skill for interface language.

# Writing for Interfaces

Good interface writing is invisible. When words work seamlessly with design, people don't
notice them.

Writing should be part of the design process from the start, not something filled in at the
end. When words are considered alongside layout, interaction, and visual design, the result
feels seamless. When they're an afterthought, product experiences feel stitched together.

Every piece of text in an interface is a small act of communication: it should respect the
person's time, meet them where they are, and help them move forward.

## When triggered

### Step 1: Establish voice and personality

Voice is the foundation. All copy decisions — what to say, how to say it, what to leave
out — flow from a clear understanding of who this product is, who it's for, and how it
should sound. Without a defined voice, copy becomes inconsistent and the product loses coherency.

**Search for an existing voice definition.** Check for:

- A `CLAUDE.md`, `AGENTS.md`, or similar project config that defines voice and/or tone
- A style guide, design system documentation, or brand guidelines
- A word list or terminology reference

**If a voice definition exists**, use it as the lens for all copy work. If the copy you're
working on drifts from it, flag the inconsistency.

**If no voice definition exists**, infer the current voice from existing copy. Look for
patterns: formal or casual? Technical or plain? Warm or matter-of-fact? If the copy is
inconsistent or insufficient to infer from, help the user establish a voice before writing.

#### Establishing voice through conversation

Walk the user through these questions:

1. **What does the product do and who is it for?** A banking app for professionals and a
   savings app for kids serve similar purposes but should sound completely different. The
   audience determines vocabulary, complexity, and register.

2. **Why do people use it, and where?** Someone using a health app during a crisis needs
   calm clarity. Someone browsing a game at home can handle playfulness. The context of use
```
