Other token exports

The JSON above is one of several output formats. The same extraction can produce:

  • --dtcgW3C Design Tokens format. Validate any DTCG file with the DTCG Validator.
  • --design-mdA readable DESIGN.md summary for agents and docs. More on its limits in DESIGN.md is a good idea with a low ceiling.
  • --brand-guideA brand guide PDF generated from the live URL.
  • --wcagA full WCAG contrast report across the palette, the same grades shown above. Why it matters in catching token drift.

See every flag in the CLI quickstart, or pull tokens straight into your editor with the Dembrandt MCP server.
