Asc Localize Metadata

If you're shipping an iOS app to multiple markets, this skill automates the tedious work of translating App Store metadata across 40+ locales. It pulls your English descriptions, keywords, and release notes from App Store Connect via the asc CLI, sends them through an LLM with locale-specific translation rules (formal tone, culturally adapted keywords, strict character limits), then pushes everything back. The translation prompts are thoughtful: they remind Claude not to literally translate keywords but to research what users actually search for in each market, and to use formal registers where appropriate (German Sie, French vous, etc.). Handles both per-version fields like descriptions and app-level fields like subtitles. Saves hours of copy-paste and helps you avoid the rookie mistakes that make localized listings feel machine-generated.

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).
Output defaults are TTY-aware: table in interactive terminals and JSON in CI or other non-interactive contexts. Use explicit --output when the format matters.
Prefer deterministic ID-based operations. Do not "pick the first row" via head -1 unless the user explicitly agrees.
