Cmux Localization

If you're working on cmux and touching anything users see, this enforces the localization workflow. It reminds you to wrap strings in `String(localized:)`, add keys to `Localizable.xcstrings` for both English and Japanese, and never ship bare literals in SwiftUI components, alerts, or menus. The audit checklist is the real value: it walks you through enumerating changed surfaces, verifying entries exist for all locales, and grepping for stray English before you finish. It also covers the less obvious stuff like schema descriptions, command help text, and web message catalogs. Honestly feels like the kind of guardrail you write after shipping untranslated text to production once too often.

cmux Localization

Use this skill for any user-facing string change.

Normal contributor flow

After adding or changing user-facing copy, run ./scripts/localize-changes.

The command compares the current worktree with the mainline base, discovers changed Swift localization keys and English web messages, prepares simple new or changed macOS catalog entries with minimal edits, and writes a machine-readable translation packet under git metadata. Fill value for simple translations or localization for plural or variant entries, then run the same command again. When an existing translation is still correct after an English change, fill value with that same text; the packet remembers the confirmation so later runs do not mark it for review again. Completed macOS rows are imported through scripts/localization_catalog.py merge, and scripts/localization_catalog.py check remains the final authoritative validator.
