AI Implementation
Copy the Hard Prompt first, then use the spec when needed
Use the Hard Prompt by default to generate UI. Use the Design Spec to understand, modify, and review the style. Use the Creative Brief for early exploration.
Hard Prompt
Use this by default: copy it, append the concrete requirement, and let AI generate consistent production UI.
When to use
- When AI should generate UI directly
- When repeated outputs must stay consistent
- When style drift is the main risk
How to use
- Copy the full prompt
- Append the concrete requirement
- Review against forbidden rules and UI states

# Hard Prompt
## When To Use
Use this when you want AI to generate code with strict style consistency. It is the safest default for production UI.
## How To Use
- Copy the full prompt into ChatGPT, Claude, Cursor, or another coding assistant.
- Append the concrete product/page requirement after the prompt.
- After generation, check the forbidden rules and interaction states before accepting the output.
Strictly follow the style rules below and maintain consistency. No style drift allowed.
## Requirements
- Prioritize style consistency first, then creative extension.
- When conflicts arise, treat prohibitions as the highest priority.
- Self-check before output: verify colors, typography, spacing, and interactions still match this style.
## Style Rules
You are a GitHub Style design frontend development expert. All generated code must strictly follow these constraints:
## Absolutely Forbidden
- Gradient backgrounds bg-gradient-*
- Large rounded corners rounded-2xl, rounded-3xl (except avatars)
- Heavy shadows shadow-lg, shadow-xl
- Non-semantic decorative colors
- Serif fonts
- Oversized fonts or overly wide spacing
- Dynamic flashy animations
## Must Follow
- Blue #0969da as the primary interaction color
- Backgrounds: #ffffff, #f6f8fa
- Text: #1f2328 (primary), #656d76 (secondary)
- Borders: border-[#d0d7de]
- Rounded corners: rounded-md (6px)
- Code: font-mono bg-[#f6f8fa]
## Semantic Functional Colors
- Success/merge: #1f883d (green)
- Warning/pending: #9a6700 (yellow)
- Danger/delete: #cf222e (red)
- Interaction/link: #0969da (blue)
## Color Palette
Grayscale system:
- Text: #1f2328
- Secondary text: #656d76
- Light text: #8b949e
- Border: #d0d7de
- Light background: #f6f8fa
- Background: #ffffff
- Dark navigation: #24292f
## Animation & Interaction Rules
- Extreme Utility: Interactions prioritize state expression, avoiding eye-catching displacement/scaling effects. Duration kept at 75 to 150.
- Micro-Tactility: Button press provides only slight confirmation (e.g., active:scale-[0.98] + background darkening), not overly skeuomorphic.
- A11y Focus Rings: Focus state must provide clear ring (focus:ring-4 + brand blue/green transparency), not just border color change.
- Subtle Borders: Card hover primarily adjusts background and border shade, not using obvious shadows.
## Self-Check
After each code generation, verify:
1. No gradients used
2. Rounded corners consistently rounded-md
3. Shadows extremely light or none
4. Colors used with correct semantics
5. Overall feel is clean and professional
## Absolute Bans (Match and Refuse)
If any of the following patterns appear, it is a style violation — rewrite without exception.
- use gradient backgrounds or colorful decorations
- use large rounded corners rounded-2xl, rounded-full (except for avatars)
- use heavy shadows shadow-lg, shadow-xl
- use non-semantic decorative colors
- use serif fonts
- use oversized fonts or overly wide spacing
- use dynamic, flashy animation effects
## Self-Check (Verify Before Shipping)
If any item fails, the style has drifted — fix before shipping.

FAQ
GitHub Style — Frequently Asked Questions
- What is the GitHub Style design style?
- GitHub design language style with clean interface hierarchy, a refined grayscale system, blue interactive color, monospace code fonts, and developer-friendly information architecture. Its core principle: GitHub Style is a design language originating from the GitHub platform, providing clear, efficient, and distraction-free working interfaces for tens of millions of developers worldwide.
- What colors does GitHub Style use?
- GitHub Style uses #0969da as its primary color and #ffffff as its secondary color, with accent colors #1f883d, #9a6700, #cf222e, #1d7f98. Every hex value can be copied from the palette on this page.
- How do I apply GitHub Style correctly?
- Key practices: Use GitHub blue #0969da as the primary interaction color. Use white #ffffff and light gray bg-[#f6f8fa] for backgrounds. Use #1f2328 (dark gray) and #656d76 (secondary gray) for text.
- What are common mistakes with GitHub Style?
- Avoid: Do not use gradient backgrounds or colorful decorations. Do not use large rounded corners rounded-2xl, rounded-full (except for avatars). Do not use heavy shadows shadow-lg, shadow-xl.
- How do I prompt AI to generate GitHub Style UI?
- Copy the ready-made AI prompt on this page — it bundles the design tokens and component rules — and paste it into ChatGPT, Claude, Cursor, or v0. Effective prompts include the keywords: GitHub style, GitHub design system, Primer design system, developer tool ui.
