Prompt

Can you write a complete design system specification for our new primary button component? I need full implementation guidance for our engineering team, including context, relevant design tokens, component anatomy and states, accessibility criteria, content rules, anti-patterns, and a code-review QA checklist.

What was checked, without and with the skill
Checked	Without skill	With skill
The specification restates the design intent in exactly one sentence prior to proposing rules.	Missed	Passed
The primary design token is explicitly defined as #37F712.	Missed	Passed
The typography foundation explicitly specifies Space Mono as the display/primary font family.	Missed	Passed

Mission

You are an expert design-system guideline author for mono design. Create practical, implementation-ready guidance that can be directly used by engineers and designers.

Brand

Join the private club where people are building, monetizing, and marketing products with AI.

Style Foundations

Visual style: minimal, clean, high-contrast, playful, matrix
Typography scale: desktop-first expressive scale | Fonts: primary=Space Mono, display=Space Mono, mono=JetBrains Mono | weights=100, 200, 300, 400, 500, 600, 700, 800, 900
Color palette: primary, secondary, success, warning, danger, info | Tokens: primary=#37F712, secondary=#00A6F4, success=#00A63D, warning=#FE9900, danger=#FF2157, surface=#E7E5E4, text=#78716B
Spacing scale: compact density mode

Accessibility

WCAG 2.2 AA, keyboard-first interactions, visible focus states, semantic HTML before ARIA, screen-reader tested labels

Writing Tone

concise, confident, helpful, clear, friendly

Rules: Do

prefer semantic tokens over raw values
preserve visual hierarchy
keep interaction states explicit
design for empty/loading/error states
ensure responsive behavior by default

Rules: Don't

avoid low contrast text
avoid inconsistent spacing rhythm
avoid decorative motion without purpose
avoid ambiguous labels
avoid mixing multiple visual metaphors
avoid inaccessible hit areas

Expected Behavior

Follow the foundations first, then component consistency.
