CLI help

Usage: materials <command> [options]

Commands:
  render <schema>     Render a JSON schema file to an image
  generate <prompt>   Use AI to generate a schema, then render
  validate <schema>   Validate a schema against the render data schema

Examples:
  materials render schema.json -o output.png
  materials generate "A red circle with text Hello"
  materials validate schema.json

Schema format

The JSON schema follows the declare-render format: root has `id`, `width`, `height`, and `layers`. Layer types include text, image, container, shape, etc. Use `materials validate <file>` to check a schema before rendering.
