web-coder

web-coder is an agent skill from the github/awesome-copilot collection that gives an agent a web development expert's knowledge across the stack. It covers HTML semantics, CSS, JavaScript, the web APIs such as the DOM, Fetch, WebRTC and WebSockets, the HTTP and networking concepts beneath them, accessibility with ARIA and WCAG, performance measures such as caching, lazy loading and code splitting, web security measures such as CORS, CSP and authentication, the standards bodies W3C and WHATWG, browser-specific bugs and cross-browser compatibility, and the servers, CDNs and infrastructure that web applications run on. The skill is meant for translating requirements into standards-compliant, accessible and performant web solutions, and for discussing web topics clearly with collaborators. It is useful for developers who work across the front end and back end and want a reference that reaches from markup to the network. A broad knowledge base is no substitute for testing, so the code and configuration it produces should be checked in real browsers and against the security settings the application needs. The skill is installed with the skills CLI from the github/awesome-copilot repository. Its skills.sh page showed about 5.5K installs and passing results from three security audits at the time of the scan.…
