Impeccable
The design language that makes your AI harness better at design
Impeccable is a design skill system that helps AI coding tools produce better frontend interfaces by giving them a richer design vocabulary. It provides one comprehensive skill, multiple commands, and curated reference files covering typography, color, motion, spacing, interaction, responsive design, and UX writing. The project is built to counter common AI-generated design habits such as generic SaaS layouts, overused fonts, nested cards, weak hierarchy, and predictable gradients. It can be installed across several AI coding environments, including Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot, and others. Impeccable also includes deterministic anti-pattern detection through a CLI and browser extension without requiring an API key. It is most useful for developers and designers who want AI-generated interfaces to feel more polished, intentional, and product-aware. -

Synthwave ’84 (VSCode Theme)
Synthwave inspired colour theme for VS Code
synthwave-vscode is a visual theme extension for Visual Studio Code that gives the editor a retro, neon-drenched look reminiscent of 1980s synthwave aesthetics. It applies a dark base palette with bold accent colors, glowing highlights, and sharp contrasts to bring an edgy, stylized atmosphere to coding sessions. Syntax highlighting is tuned to balance readability with dramatic flair, ensuring code elements don’t get lost while preserving the cool visual vibe. The theme also includes optional “neon glow” effects on UI elements, cursor styles, and sidebars for users who want a more immersive style. Many users choose it to inject personality into their development environment—especially in late-night coding sessions.

Markdown

Markdown documents are automatically rendered into WeChat graphics and text in real-time, so you no longer have to worry about the typesetting of WeChat articles!

In addition, for domestic (China) friends, accessing Gitee Pages will be relatively faster. The existing open-source WeChat Markdown editor has complicated styles and does not meet my personal aesthetic needs. When I use them for article typesetting, I often have to make some changes myself, which is time-consuming and labor-intensive, so I did secondary development. -

Random Color
A tiny script for generating attractive colors
A color generator for JavaScript. There are lots of clever one-liners for generating random colors. Unfortunately, this code naturally produces murky greys, browns and greens. randomColor generates attractive colors by default. More specifically, randomColor produces bright colors with a reasonably high saturation. This makes randomColor particularly useful for data visualizations and generative art. Once you’ve included randomColor.js on your page, calling randomColor() will return a random attractive color. Beneath is the output of randomColor called 54 times. You can also pass an options object to randomColor. This allows you to specify the hue, luminosity and the number of colors to generate. -

GitHub Dark
Dark GitHub style
GitHub-Dark is a userstyle that transforms GitHub’s interface into a coherent dark theme, covering repositories, issues, pull requests, gists, and profile pages. Distributed as a CSS stylesheet intended for the Stylus browser extension, it applies a comprehensive palette, rebalances contrast, and refines syntax colors for code views to ensure readability in low-light settings. The project goes beyond simple inversion by thoughtfully adjusting backgrounds, borders, badges, and diff highlights so the UI feels native rather than “flipped.” It includes targeted fixes for edge cases across GitHub’s many subpages, aiming for consistency while preserving the information hierarchy of the original design. Users can apply the theme selectively, override variables, or combine it with other userstyles to fit personal preference. Even with GitHub’s own theme options, GitHub-Dark remains a carefully tuned alternative for people who want a specific aesthetic or more granular control. -
