## What it does

The skill acts as a naming-convention auditor. It scans the project to find the dominant filename casing, checks suffix patterns such as `.test.ts` versus `.spec.ts`, and looks at how exports and index files are named. By default it only reports: each finding comes as `path:line`, a description of what is wrong, and the suggested fix. Findings are grouped under HIGH, MEDIUM and LOW, with a violation count per rule at the end.

The casing, suffix, export-naming and index-file rules are language-neutral, so they apply to any project. A separate framework rule set loads only when Next.js or Expo shows up in `package.json`. The skill runs on `haiku` and its tools are limited to `Read`, `Glob`, `Grep`, `Edit` and `Bash(git:*)`.

Edits happen only when you ask for them. Then it renames files with `git mv`, updates import paths in dependent files, and verifies that no broken imports remain. A vague request gets a report first. Worth knowing before you run it: dynamic imports and string-based paths are easy to miss, so run your tests after a rename pass.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill naming-format -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill naming-format -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill naming-format -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tartinerlabs/skills naming-format
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill naming-format -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tartinerlabs/skills --path plugins/quality/skills/naming-format
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill naming-format -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/tartinerlabs/skills/tree/HEAD/plugins/quality/skills/naming-format/SKILL.md

## When to use it
- spot files with mixed casing in one directory
- unify test suffixes across the repo
- check export names before publishing a package
- map the conventions of an unfamiliar codebase
- rename files and update the imports that point at them

## Example prompts
- audit the file names in this project and show me where the conventions break
- rename the files in src/utils to one style and fix the imports
- check the exports in this package and tell me if the naming is consistent

You are a naming conventions expert.

Audit and report by default; rename files or edit exports only when the user asks you to fix, rename, or standardise something. When the ask is unclear, report first and offer to apply the fixes.

## Rules Overview

| Rule | Impact | File |
|------|--------|------|
| Case consistency | HIGH | `rules/case-consistency.md` |
| File suffixes | HIGH | `rules/file-suffixes.md` |
| Export naming | HIGH | `rules/export-naming.md` |
| Index files | HIGH | `rules/index-files.md` |
| Framework conventions | MEDIUM | `rules/framework-conventions.md` (only when a supported framework is detected) |

## Workflow

### Step 1: Detect

Scan the project to identify:

- Dominant filename casing convention (count files by pattern)
- Framework indicators (e.g. Next.js/Expo in `package.json`) — used only to decide whether to load `rules/framework-conventions.md`
- Existing suffix patterns (`.test.ts` vs `.spec.ts`, etc.)
- Export naming patterns across the codebase

The casing, suffix, export-naming, and index-file rules are language-neutral and always apply. Load `rules/framework-conventions.md` **only when a supported framework (Next.js / Expo) is detected**.

### Step 2: Audit

Check all files and exports against the rules.

Report each finding as `path:line` — what is wrong → the fix, grouped under `### HIGH` / `### MEDIUM` / `### LOW`, and close with a per-rule violation count.

### Step 3: Fix

Apply fixes for each violation:
1. Rename files with `git mv`
2. Update all import paths in dependent files
3. Verify no broken imports remain after renames
