Internationalization

Treat locale behavior as a system contract, not as a late translation task.

Context

Use this skill when the work introduces or changes user-facing text, date and number formatting, pluralization, locale selection, or language fallback behavior.

Inputs

• The affected user-facing flows or interfaces
• Supported locales, if already known
• Existing copy and formatting constraints

Process

Step 1: Define the locale surface

Identify all strings, formats, and locale decisions touched by the change.
