## What it does

This skill runs an offline ASO audit across canonical App Store metadata files under `./metadata` fetched with `asc metadata pull`. It inspects your JSON records to pinpoint wasted keyword budget, such as tokens already present in the subtitle or app name that needlessly consume space in the 100-character keyword field.

It validates formatting issues like spaces after commas, pipes, or semicolons, and flags underutilized fields where keywords take under 90 characters or subtitles take fewer than 20. The check also flags non-primary locales where keywords simply duplicate `en-US`, and reviews whether search terms appear naturally inside the app description.

The audit requires strict directory conventions in `./metadata`; exports from `asc migrate export` or `asc localizations download` must be normalized first, or the checks will fail on missing file paths.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add rorkai/app-store-connect-cli-skills --skill asc-aso-audit -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add rorkai/app-store-connect-cli-skills --skill asc-aso-audit -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add rorkai/app-store-connect-cli-skills --skill asc-aso-audit -a cursor
```

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

### GitHub Copilot

gemini skills install https://github.com/rorkai/app-store-connect-cli-skills --path skills/asc-aso-audit
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add rorkai/app-store-connect-cli-skills --skill asc-aso-audit -a opencode
```

### Claude.ai

## When to use it
- find duplicate tokens between subtitle and keywords
- catch formatting errors like spaces after commas in keywords
- flag underutilized character limits in App Store metadata
- detect unlocalized keyword sets identical to en-US

## Example prompts
- Run an offline ASO audit on the ./metadata folder
- Check metadata/version/ for underutilized character limits and bad separators
- Audit keyword overlap between subtitle and keywords for en-US

# asc ASO audit

Run a two-phase ASO audit: offline checks against local metadata files, then keyword gap analysis via Astro MCP.
When available, include Apple-generated app tags as a discoverability signal.

## Preconditions

- Metadata pulled locally into canonical files via `asc metadata pull --app "APP_ID" --version "1.2.3" --dir "./metadata"`.
- If metadata came from `asc migrate export` or `asc localizations download`, normalize it into the canonical `./metadata` layout before running this skill.
- For Astro gap analysis: app tracked in Astro MCP (optional — offline checks run without it).
- For Apple-generated discoverability tags: `asc app-tags list --app "APP_ID" --output json` works when the API returns tags for the app.

## Before You Start

1. Read `references/aso_rules.md` to understand the rules each check enforces.
2. Identify the **latest version directory** under `metadata/version/` (highest semantic version number). Use this for all version-level fields.
3. The **primary locale** is `en-US` unless the user specifies otherwise.

## Metadata File Paths

- **App-info fields** (`subtitle`): `metadata/app-info/{locale}.json`
- **Version fields** (`keywords`, `description`, `whatsNew`): `metadata/version/{latest-version}/{locale}.json`
- **App name**: May not be present in exported metadata. If `name` is missing from the app-info JSON, fetch it via `asc apps info list` or ask the user. Do not flag it as a missing-field error.

## Phase 1: Offline Checks

Run these 5 checks against the local metadata directory. No network calls required.

### 1. Keyword Waste

Tokenize the `subtitle` field (and `name` if available). Flag any token that also appears in the `keywords` field — it is already indexed and wastes keyword budget.

```
Severity: ⚠️ Warning
Example:  "quran" appears in subtitle AND keywords — remove from keywords to free 6 characters
```

How to check:
1. Read `metadata/app-info/{locale}.json` for `subtitle` (and `name` if present)
2. Read `metadata/version/{latest-version}/{locale}.json` for `keywords`
3. Tokenize subtitle (+ name):
   - **Latin/Cyrillic scripts:** split by whitespace, strip leading/trailing punctuation, lowercase
   - **Chinese/Japanese/Korean:** split by `、` `，` `,` or iterate characters — each character or character-group is a token. Whitespace tokenization does not work for CJK.
