software-design-philosophy is a reusable agent skill based on John Ousterhout's A Philosophy of Software Design. It gives coding assistants a design framework for code reviews, architecture discussions, API design, module decomposition, refactoring, naming, comments, and error-handling strategy. Users can install it in Claude Code, Codex, or compatible skill managers and invoke it alongside an existing project. The repository supplies guidance for making software-design decisions; it is not a standalone static analyzer or development application.

How to Contribute to Open Source is a multilingual resource list for people making their first contributions. It gathers introductory articles, GitHub search approaches, version-control material, books, community initiatives, and programs that welcome contributors. The repository is an educational index rather than an automation tool; readers can suggest additional resources through pull requests when they find useful omissions.

Use an AI coding agent to review and improve web projects against Lighthouse guidance, Core Web Vitals patterns, WCAG 2.2 accessibility practices, SEO requirements, and modern browser standards. The skills work across major frameworks or plain HTML and can be invoked by topic, but this is an unofficial collection intended as structured engineering guidance rather than an official certification tool.

Determine whether a Chrome, Edge, Chromium, or Electron environment can decode or encode HEVC in hardware before shipping video features. The guide maps codec profiles, HDR behavior, operating systems, GPUs, drivers, and browser versions, then shows capability checks with MediaCapabilities, Media Source, WebCodecs, WebRTC, and MediaRecorder. It also documents patches and build paths for custom Chromium or Electron distributions. Results vary substantially by platform and version, so browser branding alone is not a reliable compatibility test.
