Connect Design Prover to your AI client to stop it from hallucinating random hex codes and inconsistent padding. It forces every line of code to follow your existing design system.

Short answer

How do I stop my AI from writing messy, inconsistent CSS?

You give the AI access to your design tokens through Design Prover. It checks every CSS property against your specific scales to ensure nothing drifts from your brand. You get code that actually fits your system without manual cleanup.

The outcomes.

Where your design stays consistent.

The AI uses your design rules to validate code output.

VALIDATION

Standardized CSS output

The AI runs prove_design to check colors and spacing. You get code that uses your exact design tokens instead of random values.

AUDIT

Design drift detection

The AI identifies where the generated code breaks your rules. It flags any hex codes or pixel values that don't exist in your system.

REPAIR

Automated corrections

The AI rewrites non-compliant styles. It swaps out invalid values for the closest matching token from your scale.

HUMAN

Final design review

The AI highlights the specific rules it had to enforce. You decide if the automated adjustments match your visual intent.

The workflow

What your AI does when code arrives.

The AI acts as a gatekeeper between its creative output and your production codebase.

  1. Scan the code

    The AI reads the generated CSS or component code to find all color, spacing, and typography declarations.

    prove_design

  2. Compare to tokens

    It checks every value against your design system's allowed scales and variables.

    prove_design

  3. Identify violations

    The AI isolates any hardcoded values that deviate from your established design language.

    prove_design

  4. Apply fixes

    The AI replaces the offending values with the correct tokens to bring the code into compliance.

    prove_design

  • Check the CSS in ./src/components/Button.tsx against my design tokens.

  • Review this Tailwind config and ensure all colors match my brand scale.

  • Audit the styles in my latest pull request for any hardcoded spacing values.

  • Rewrite this component's styles to use only the tokens defined in my theme file.

FAQ

How this task behaves.

  • 01

    Can the AI change my actual design token files?

    No. The AI only reads your tokens to validate code. It cannot modify your source design files.

  • 02

    Does it work with any CSS framework?

    Yes, as long as the AI can read the code and you provide the design rules for it to check against.

  • 03

    Will it automatically commit code to my repo?

    No. The AI provides the corrected code in the chat, and you must manually review and commit it.

  • 04

    What happens if a color doesn't exist in my scale?

    The AI will flag it as a violation and suggest the closest valid token from your system.

  • 05

    Can it check layout logic like Flexbox or Grid?

    It focuses on design tokens like color, spacing, and typography. It does not validate complex layout math.
