- LOC-36 [Keep app strings in the platform's resource files](https://agentwranglers.se/playbook/localization/apps-and-command-line-tools/platform-string-resources.md) · 863 tokens · updated 2026-10-22
  Phone and desktop apps keep every visible text in the platform's resource format, with plural variants, and never as text in the code. A lint check fails on hard-coded text.
- LOC-37 [Support the system's per-app language setting](https://agentwranglers.se/playbook/localization/apps-and-command-line-tools/per-app-language.md) · 974 tokens · updated 2026-10-22
  Declare every language the app ships so iOS and Android list it in the system's per-app language setting. An in-app language picker opens that setting or uses the platform API, instead of a separate home-made switch.
- LOC-38 [Translate the store listing for every language the app ships](https://agentwranglers.se/playbook/localization/apps-and-command-line-tools/localized-store-listings.md) · 970 tokens · updated 2026-10-22
  Each language the app ships has a store listing in that language, with name, short description, full description, keywords and screenshots. The listing never claims a language the app does not have.
- LOC-39 [Make command-line tools read the locale or say they do not](https://agentwranglers.se/playbook/localization/apps-and-command-line-tools/cli-locale.md) · 793 tokens · updated 2026-10-22
  A command-line tool that prints translated text picks its language from `LC_ALL`, then `LC_MESSAGES`, then `LANG`. A tool in one language says so in its help. Machine-readable output is the same in every locale.
