+# Hygiene Checks
+
+VS Code runs a hygiene check as a git pre-commit hook. Commits will be rejected if hygiene fails.
+
+## What it checks
+
+The hygiene linter scans all staged `.ts` files for issues including (but not limited to):
+
+- **Unicode characters**: Non-ASCII characters (em-dashes, curly quotes, emoji, etc.) are rejected. Use ASCII equivalents in comments and code.
+- **Double-quoted strings**: Only use `"double quotes"` for externalized (localized) strings. Use `'single quotes'` everywhere else.
+- **Copyright headers**: All files must include the Microsoft copyright header.
+
+## How it runs
+
+The git pre-commit hook (via husky) runs `npm run precommit`, which executes:
+
+```bash
+node --experimental-strip-types build/hygiene.ts
+```
+
+This scans only **staged files** (from `git diff --cached`). To run it manually:
+
+```bash
+npm run precommit
+```
