dcyfr-design-tokens

What I do

I enforce strict design token compliance across the DCYFR portfolio project by:

• •Detecting hardcoded Tailwind values (gap-8, text-3xl, max-w-4xl, etc.)
• •Replacing them with proper design tokens from @/lib/design-tokens
• •Validating color, spacing, typography, and container width usage
• •Providing ESLint auto-fix guidance for common violations

When to use me

✅ Use this skill when:

• •Fixing ESLint design token violations (@dcyfr/design-tokens/*)
• •Converting legacy code to use design tokens
• •Reviewing PRs for token compliance
• •Implementing new components following DCYFR patterns

❌ Don't use this skill for:

• •General Tailwind CSS questions (use documentation)
• •Non-DCYFR projects (patterns are project-specific)
• •Performance optimization (use dcyfr-performance skill)

Core Rules (NON-NEGOTIABLE)

1. Import Design Tokens

// ✅ CORRECT: Import tokens
import { SPACING, TYPOGRAPHY, CONTAINER_WIDTHS, COLORS } from "@/lib/design-tokens";

// ❌ WRONG: Hardcoded values
<div className="gap-8 text-3xl max-w-4xl text-gray-900">

2. Use Token Categories

3. Common Replacements

// Spacing
gap-8     → gap-${SPACING.content}
mt-16     → mt-${SPACING.section}
p-4       → p-${SPACING.card}

// Typography
text-3xl  → ${TYPOGRAPHY.h1.standard}
text-sm   → text-base (use standard sizes)

// Containers
max-w-4xl → ${CONTAINER_WIDTHS.standard}
max-w-7xl → ${CONTAINER_WIDTHS.wide}

// Colors
text-gray-900     → ${COLORS.text.primary}
bg-neutral-50     → ${COLORS.background.subtle}

Validation Commands

# Check design token compliance
npm run lint

# Auto-fix violations
npm run lint -- --fix

# Enhanced validation (OpenCode-specific)
npm run check:opencode

ESLint Rules

The project uses custom ESLint rules to enforce design tokens:

• •@dcyfr/design-tokens/no-hardcoded-spacing - Blocks gap-*, mt-*, p-*
• •@dcyfr/design-tokens/no-hardcoded-typography - Blocks text-* size utilities
• •@dcyfr/design-tokens/no-hardcoded-containers - Blocks max-w-*

Target: ≥90% design token compliance

Common Patterns

Blog Post Card

import { SPACING, TYPOGRAPHY, CONTAINER_WIDTHS } from "@/lib/design-tokens";

export function PostCard() {
  return (
    <article className={`flex flex-col gap-${SPACING.content}`}>
      <h2 className={TYPOGRAPHY.h2.standard}>
        {title}
      </h2>
      <div className={`mt-${SPACING.content}`}>
        {excerpt}
      </div>
    </article>
  );
}

Page Layout

import { PageLayout } from "@/components/layouts";
import { CONTAINER_WIDTHS, SPACING } from "@/lib/design-tokens";

export default function Page() {
  return (
    <PageLayout>
      <div className={`mx-auto ${CONTAINER_WIDTHS.standard}`}>
        <div className={`mt-${SPACING.section}`}>
          Content
        </div>
      </div>
    </PageLayout>
  );
}

Approval Gates

Design token violations are STRICT (hard block):

• •❌ PR builds fail with ESLint errors
• •❌ Pre-commit hooks warn about violations
• •✅ Must fix before merging

No exceptions - design tokens are mandatory for visual consistency.
