Ensure consistency by producing shared artifacts, automated checks before parallel work begins.
Phase 1 (sequential): create shared artifacts (tokens, Layout, UI components). Phase 2 (parallel): every page imports from Phase 1; no new tokens or duplicated components.
| Artifact | Path | Page Agent Rules |
|---|---|---|
| Design tokens | src/styles/tokens.css | Import only. Never introduce new color/font/spacing values. |
| Shared layout | src/components/Layout.tsx / Layout.astro | Wrap every page. Never recreate. |
| UI components | src/components/ui/ | Import from library. PascalCase components, camelCase props. |
| Style guide brief | Inline in prompts | Match tone + terminology exactly. Follow heading hierarchy. |
Validation checkpoints:
tokens.css has all palette/type/spacing vars, Layout renders, UI components compile.grep -r .style={{. src/pages/ returns 0 hits (no inline styles). All imports resolve.Phase 1 (sequential): foundation-setup creates tokens, Layout, UI library, style guide brief. Phase 2 (parallel): every page task imports from Phase 1. Include these 5 references in every page prompt:
1. Design tokens path 2. Layout path 3. UI components path
4. Aesthetic direction 5. Content tonePrompt templates: see TEMPLATES.md.
src/styles/tokens.css:root {
/* Palette */
--color-bg: #ffffff;

--color-primary-600: #0284c7;
/* Typography */
--font-base: 'Inter, system-ui, -apple-system, sans-serif';
--text-sm: 0.875rem;
--text-base: 1rem;
/* Spacing */
--space-1: 4px;
--space-2: 8px;
--space-3: 16px;
/* Radius */
--radius-sm: 6px;
--radius-md: 12px;
}import './tokens.css';
type ButtonProps = { children: React.ReactNode; variant?: 'primary' | 'ghost'; className?: string };
export function Button({ children, variant = 'primary', className = '' }: ButtonProps) {
const base = 'px-4 py-2 rounded';
const variantCls = variant === 'primary' ? 'bg-[var(--color-primary)] text-white' : 'bg-transparent';
return <button className={`${base} ${variantCls} ${className}`}>{children}</button>;
}| Anti-pattern | Fix |
|---|---|
| Agents pick their own fonts/colors | Foundation creates tokens first |
Copy-pasting Button between pages | Import from shared library |
Inline style={{ color: '#...' }} | CSS class with token variable |
| Foundation and page tasks run in parallel | Foundation phase must fully complete first |

If you maintain this skill, you can claim it as your own. Once claimed, you can manage eval scenarios, bundle related skills, attach documentation or rules, and ensure cross-agent compatibility.
