Hygiene Checks

VS Code runs a hygiene check as a git pre-commit hook. Commits will be rejected if hygiene fails.

Running the hygiene check

Always run the pre-commit hygiene check before declaring work complete. This catches issues that would block a commit.

To run the hygiene check on your staged files:

npm run precommit

This executes node --experimental-strip-types build/hygiene.ts, which scans only staged files (from git diff --cached).

To check specific files directly (without staging them first):

node --experimental-strip-types build/hygiene.ts path/to/file.ts

What it checks

The hygiene linter scans staged 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. Suppress with // allow-any-unicode-next-line or // allow-any-unicode-comment-file.
  • 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.
  • Indentation: Tabs only, no spaces for indentation.
  • Formatting: TypeScript files must match the formatter output (run Format Document to fix).
  • ESLint: TypeScript files are linted with ESLint.
  • Stylelint: CSS files are linted with stylelint.

How to use it

Copy the folder

Take microsoft/hygiene from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
