## What it does

This skill holds review rules for any text a user ends up reading. That covers status and diagnostic output, error and help messages, the shape of README and docs, code comments, headings, plus generated reports, decks and exports. Each rule ships with a counter-example taken from a defect caught in review, since the reasoning is the point.

The rules split into status output, error messages and documentation. A status display should resolve values the way the runtime does, environment variables and layered config included, so it reports what the next run will actually use. Diagnostics have to stay honest when something breaks: if one config layer fails to load, fall back to the most complete state that still loads rather than blank defaults. Machine-readable output counts as a contract, so notices and annotations stay out of it.

Docs are split by responsibility. A fact gets one canonical home and other pages link to it; restating the same content and then pointing at the source is treated as a bug. Rationale belongs in a design record or the pull request, not in a how-to, because the steps readers came for get pushed down and the argument ages first. The skill installs into Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode; for Windsurf (Devin Desktop) only the skill file path is given.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill ux-writing -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill ux-writing -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill ux-writing -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install scarletkc/agents ux-writing
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill ux-writing -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/scarletkc/agents --path skills/ux-writing
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill ux-writing -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/scarletkc/agents/tree/HEAD/skills/ux-writing/SKILL.md

## When to use it
- make a status command report effective values, not stored ones
- keep diagnostics truthful when a config layer fails to load
- give one fact a single canonical home across docs
- strip annotations out of porcelain, TSV and JSON output
- review a diff that touches copy or documentation

## Example prompts
- Review the error messages in this module: what happened, where, and what to do next
- Split the README by responsibility and tell me which page owns each fact
- Check this diff for annotations leaking into the JSON output

# UX Writing & Docs

User-visible text is product behavior and carries the same quality bar as
code. Every rule below is distilled from a real defect caught in review, and
keeps its counter-example because the reasoning is the point. When in doubt,
re-read the output as the user who just hit the problem.

## Status output & diagnostics

- **Report effective values, not stored ones.** A status display answers
  "what will happen when I run this", so resolve values exactly the way the
  runtime does, including environment variables and layered config.
  *Counter-example: a config viewer printed "API key set: no" while an env
  var held the key the next run would actually use.*
- **Diagnostics must stay truthful under failure.** When one config layer
  fails to load, fall back to the most complete state that still loads,
  never to blank defaults. A diagnostic that misreports is worse than one
  that aborts. *Counter-example: a broken project-level config made a doctor
  command check blank defaults and report a missing API key that was in fact
  configured; the fake failure buried the real one.*
- **Show deltas, not dumps.** A health/diagnostic command lists what
  deviates and who set it; the exhaustive listing belongs to the dedicated
  inspect command. Don't make one command duplicate another's job.
  *Counter-example: a doctor check printed fifteen "field: origin" lines,
  most of them saying "global". One line naming the two real overrides
  replaced the block.*
- **Annotate at the granularity of the claim.** If one sub-part of a
