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. -

Configuration options typically allow tweaking accents and choosing variants that match different desktop environments and icon sets. Documentation guides users through installing prerequisites, applying the theme, and resolving common edge cases across distributions.

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. -

Chalk
Terminal string styling done right
Chalk 5 is ESM. If you want to use Chalk with TypeScript or a build tool, you will probably want to use Chalk 4 for now. Chalk comes with an easy to use composable API where you just chain and nest the styles you want. Chain styles and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that chalk.red.yellow.green is equivalent to chalk.green. Color support is automatically detected, but you can override it by setting the level property. You should however only do this in your own code as it applies globally to all Chalk consumers. Detect whether the terminal supports color. Used internally and handled for you, but exposed for convenience. chalkStderr contains a separate instance configured with color support detected for stderr stream instead of stdout. Override rules from supportsColor apply to this too. supportsColorStderr is exposed for convenience. -

Ember Paper
The Ember approach to Material Design
This project aims to bring Google's new Material Design to Ember. The goal is to encapsulate everything possible in Ember components. This project is packaged as an Ember-cli addon.

Using sass you can override default variables and easily change the default behavior of ember-paper styles. All the components and styles are ready to use in your application templates. Navigate through the docs to understand how to use each component. -

Lottie
Render After Effects animations natively on Mobile, Web & React Native
Lottie is a wonderful library for Android, iOS, Web, and Windows that works by parsing Adobe After Effects animations that have been exported as json with Bodymovin, and then rendering these natively on mobile and on the web! Now you can have beautiful animations without engineers having to recreate everything by hand. Building animations by hand is time consuming, and other animation alternatives like Gifs and Png sequences don’t offer the same flexibility and varied features that Lottie offers. With Lottie, you can achieve exquisite animations exactly how you want, with no additional engineering effort whatsoever. Take a look at the many beautiful animation possibilities available to you on http://airbnb.io/lottie/ -

Susy
Responsive layout toolkit for Sass
Susy is a design-agnostic set of tools for creating powerful, custom layouts. We didn't want another grid system full of rules and restrictions, we wanted a power tool for building our own damn systems. Version Three is trimmed down to it's most basic components, functions that can be used to build any grid system. There are two imports to choose from. The default sass/susy comes with un-prefixed versions of the core API functions. If you want Susy to be name-spaced, import sass/susy-prefix instead. To add Susy to the Sass task, edit your Gruntfile.js at the root level of your project and look for the Sass-related rules. Add require: 'susy' inside the options object. Susy is also available in the CodeKit editor, with 10% of your purchase going to Black Girls Code when you follow the link from our site. You can also still access Susy2 documentation if necessary. -
