## FAQ

### How can I use this with an AI agent like Claude Code or Cursor?

You can generate the necessary configuration by running the command `npx standards mcp-config`.

### Can the tool automatically fix design system violations?

Yes, the `standards fix` command applies fixes where possible and writes the result to a new HTML file.

### What happens if I try to disable mandatory accessibility rules?

The tool will refuse to run and exit with status 2 if you attempt to set mandatory rules like contrast or target size to warn or off.

### Does it check the actual rendered output or just the CSS?

It checks the computed values as rendered by the browser, rather than just inspecting the stylesheets.
