    Playwright Skill for Claude Code

    Playwright Skill for Claude Code

    Claude Code Skill for browser automation with Playwright

    Playwright Skill is an open-source plugin designed for Claude Code that enables dynamic browser automation using Playwright through natural language instructions. The tool allows an AI agent to generate, execute, and manage browser automation scripts on demand, rather than relying on predefined workflows or static test scripts. It is structured as a modular skill within the Claude ecosystem, meaning it can be installed as a plugin and invoked automatically when browser automation tasks are required. The system supports a wide range of use cases, including testing web applications, validating user interfaces, automating workflows, and extracting data from websites. One of its key advantages is its ability to generate custom Playwright code tailored to each request, allowing flexible and context-aware automation.

    Raphaël

    Raphaël

    JavaScript vector library

    Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library. Raphaël ['ræfeɪəl] uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy. Raphaël currently supports Firefox 3.0+, Safari 3.0+, Chrome 5.0+, Opera 9.5+ and Internet Explorer 6.0+. Versions will be released as we gather and test new PRs. As there are a lot of browsers being supported it might take a while to accept a PR, we will use the feedback from other users too. You can use the raphaelTest.html to try things, you need to start a server in the root dir to start testing things there.

    React Refresh Webpack Plugin

    React Refresh Webpack Plugin

    A Webpack plugin to enable "Fast Refresh"

    An EXPERIMENTAL Webpack plugin to enable "Fast Refresh" (also known as Hot Reloading) for React components. This plugin is not 100% stable. We're hoping to land a v1 release soon, please help us by reporting any issues you've encountered! Ensure that you are using at least the minimum supported versions of this plugin's peer dependencies - older versions, unfortunately, do not contain code to orchestrate "Fast Refresh", and thus cannot be made compatible. For most setups, we recommend integrating using babel-loader. It covers the most use cases and is officially supported by the React team. If you haven't done so, set up your development Webpack configuration for Hot Module Replacement (HMR). This plugin integrates with the most common Webpack HMR solutions to surface errors during development, in the form of an error overlay.

    Reagent

    Reagent

    A minimalistic ClojureScript interface to React.js

    Reagent is a minimalistic ClojureScript interface to React that enables developers to write efficient React components using plain ClojureScript functions and data, leveraging a Hiccup-like syntax and immutable state to simplify UI creation. React is pretty darn fast, and so is Reagent. It should even be faster than plain old javascript React a lot of the time, since ClojureScript allows us to skip a lot of unnecessary rendering (through judicious use of React's shouldComponentUpdate). The ClojureScript overhead is kept down, thanks to lots of caching. Code size is a little bigger than React.js, but still quite small. The todomvc example clocks in at roughly 79K gzipped, using advanced compilation.

    Redux-ORM

    Redux-ORM

    A small, simple and immutable ORM to manage relational data

    A small, simple and immutable ORM to manage relational data in your Redux store. Redux-ORM is fast. All queries are lazily evaluated and come with built-in support for memorization. It provides a clean abstraction over low-level updates, protecting the state from accidental mutations. With nearly 100% branch coverage, the library is thoroughly tested to ensure rock-solid code quality. No matter where your data comes from, Redux-ORM will stay out of its way. Even a custom database layer is possible. Defining fields on a Model specifies the table structure in the database for that Model. In order to generate a description of the whole database's structure, we need a central place to register all Models we want to use. An instance of the ORM class registers Models and handles generating a full schema from all the models and passing that information to the database. Often you'll want to have a file where you can import a single ORM instance across the app.

    Replace Google CDN

    Replace Google CDN

    A Chrome plugin: Replace Google CDN with domestic

    For well-known reasons, just substituting a domain name can continue to use the front-end public library provided by Google. Likewise, referencing these resources via the scripttag will instantly speed up your website access! Many websites, especially foreign websites, use Google's CDN in order to speed up the website. But in China, due to some reasons, the world's fastest CDN has become the world's slowest. So, I wrote this plugin/extension to replace Google's CDN with a domestic one. This plugin/extension can replace the cdn resources with domestic ones.

    Roboquant

    Roboquant

    User-friendly and completely free algorithmic trading platform

    Roboquant is an open-source algorithmic trading platform written in Kotlin. It is flexible, user-friendly and completely free to use. It is designed for anyone serious about algo-trading. So whether you are a beginning retail trader or an established trading firm, Roboquant can help you to quickly develop robust and fully automated trading strategies. But perhaps most important of all, it is blazingly fast. Roboquant is orders of magnitude faster than most other algo-trading platforms. With historic data sets becoming more widely available and growing in size, it is important that a strategy can still be quickly developed, back-tested and optimized. If this cycle takes too long, it is nearly impossible to create high-performing and robust strategies. A lot of effort and attention went into making sure Roboquant is easy to use, especially for less experienced developers.

    Ruler AI

    Ruler AI

    Centralize and sync AI coding rules across tools and projects

    Ruler is a CLI tool that centralizes instructions for AI coding assistants in one place. Instead of maintaining separate configuration files for tools like GitHub Copilot, Claude, or Cursor, it stores all rules in a single .ruler/ directory and distributes them automatically. This reduces duplication, avoids inconsistent outputs, and keeps guidance aligned as projects evolve. Ruler supports nested rule loading, allowing teams to define context-specific instructions for different parts of a codebase. It also manages MCP server settings, automates .gitignore updates, and provides simple commands to initialize, apply, and revert configurations. Designed for teams using multiple AI agents, it improves workflow consistency, simplifies onboarding, and ensures all assistants follow the same standards across projects.

    Soundnode App

    Soundnode App

    Soundnode App is the Soundcloud for desktop

    Soundnode App is an Open-Source project to support Soundcloud for desktop Mac, Windows, and Linux. It's built with Electron, Node.js, Angular.js, and uses the Soundcloud API. Be aware that Soundnode relies on Soundcloud API which only allows third-party apps to play 15 thousand tracks daily. When the rate limit is reached all users are blocked from playing/streaming tracks. The stream will be re-enabled one day after (at the same time) streams were blocked. Since SoundCloud applies a rate limit to third-party apps, you need to configure your own API key to make soundnode work. Unfortunately, SoundCloud suspended new application creation, so to retrieve your API key, you have to dig into the SoundCloud website. Listen to songs from your stream, likes, tracks, following or playlists.

    Space Desktop

    This project was bootstrapped with Create React App

    This project was bootstrapped with Create React App. If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project. Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own. You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

    StatiCrypt

    StatiCrypt

    Password protect a static HTML page

    StatiCrypt uses AES-256 and WebCrypto to encrypt your HTML file with your long password and return a static page including a password prompt and the javascript decryption logic that you can safely upload anywhere (see what the page looks like). This means you can password protect the content of your public static HTML file, without any back-end - serving it over Netlify, GitHub pages, etc. You can encrypt a file online in your browser (client side). StatiCrypt uses WebCrypto to generate a static, password protected page that can be decrypted in-browser. You can then just send or upload the generated page to a place serving static content (github pages, for example) and you're done: the page will prompt users for a password, and the javascript will decrypt and load your HTML, all done in the browser.

    An agentic skills framework & software development methodology

    Superpowers Framework is a widely-used agentic skills framework and methodology for software development that equips coding agents like Claude Code with structured capabilities to plan, develop, test, and review code systematically. Instead of simply generating code, Superpowers drives an AI through a thoughtful software engineering workflow that starts with clarifying project intent, teasing out a detailed specification, and creating an implementation plan that is readable and actionable. It incorporates test-driven development, task planning, and sub-agent orchestration so that each engineering task is executed, checked, and iterated upon with rigor rather than ad-hoc improvisation. Superpowers includes a rich set of modular “skills” that guide the AI in areas such as brainstorming, planning, debugging, and code review, giving it the tools to function like a disciplined developer rather than a naive auto-completer.
