How to make Claude Code design better UI

A practical loop for using Claude Code with stronger visual output.

Start with a file, not a vibe

Put the design system into DESIGN.md before you ask Claude Code to build screens.

Attach screenshots, component names, tokens, and anti-patterns so the model has something to match.

When Claude gets close but not exact, update the spec instead of repeating longer prompts forever.

Have a public DESIGN.md?

Create an account and submit the source URL so it can be reviewed and indexed in the directory.
