Chrome Extension

This is a routing skill for building Chrome extensions with Manifest V3. It breaks down extension development into 12 focused reference files covering manifest setup, service workers, content scripts, messaging patterns, UI surfaces, storage, network requests, permissions, and publishing. The architecture diagrams showing the five execution contexts and how they communicate are genuinely useful. Most helpful for developers who already understand the basics but need quick answers on specific MV3 patterns like CSP bypass relays, building an RPC layer over chrome.runtime, or handling service worker termination. If you're just adding a feature to an existing extension or debugging why your content script can't make a fetch call, the routing structure gets you to the right answer faster than reading MDN linearly.
