Materials CLI
Use this skill when the user wants to render JSON schemas to images (PNG/JPG), validate render-data schemas, or generate schemas from natural-language prompts and then render them.
Commands
- render — Render a JSON schema file to an image.
- generate — Use AI (OpenAI) to generate a schema from a prompt, then render it.
- validate — Validate a JSON schema against the declare-render data schema.
When to use
- User asks to "render a schema to image", "turn JSON into a picture", or "draw from schema".
- User wants to "generate an image from a description" or "create a schema from a prompt" and render it.
- User wants to "validate" a JSON file against the render data schema.

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"
