# asc localize metadata

Use this skill to pull English (or any source locale) App Store metadata, translate it with LLM, and push translations back to App Store Connect — all automated.

## Command discovery and output conventions

- Always confirm flags with `--help` for the exact `asc` version:
  - `asc localizations --help`
  - `asc localizations download --help`
  - `asc localizations upload --help`
  - `asc apps info edit --help`
- Prefer explicit long flags (`--app`, `--version`, `--version-id`, `--type`, `--app-info`).
- Default output is JSON; use `--output table` only for human verification steps.
- Prefer deterministic ID-based operations. Do not "pick the first row" via `head -1` unless the user explicitly agrees.

## Preconditions
- Auth configured (`asc auth login` or `ASC_*` env vars)
- Know your app ID (`asc apps list` to find it)
- At least one locale (typically en-US) already has metadata in App Store Connect

## Supported Locales

App Store Connect locales for version and app-info localizations:
```
ar-SA, ca, cs, da, de-DE, el, en-AU, en-CA, en-GB, en-US,
es-ES, es-MX, fi, fr-CA, fr-FR, he, hi, hr, hu, id, it,
ja, ko, ms, nl-NL, no, pl, pt-BR, pt-PT, ro, ru, sk,
sv, th, tr, uk, vi, zh-Hans, zh-Hant
```

## Two Types of Metadata

### Version Localizations (per-release)
Fields: `description`, `keywords`, `whatsNew`, `supportUrl`, `marketingUrl`, `promotionalText`

### App Info Localizations (app-level, persistent)
Fields: `name`, `subtitle`, `privacyPolicyUrl`, `privacyChoicesUrl`, `privacyPolicyText`

## Workflow

### Step 1: Resolve IDs

```bash
# Find app ID
asc apps list --output table

# Find latest version ID
asc versions list --app "APP_ID" --state READY_FOR_DISTRIBUTION --output table
# or for editable version:
asc versions list --app "APP_ID" --state PREPARE_FOR_SUBMISSION --output table
