A comprehensive rulebook for writing Chrome extensions with Manifest V3, covering 67 rules across service workers, content scripts, message passing, and storage APIs. Most valuable when migrating from V2 or debugging why your service worker keeps dying (use chrome.storage instead of globals, register listeners at top level). The priority system is smart: it puts critical lifecycle issues first, then optimization patterns. Specific rules like using declarativeNetRequest over webRequest and activeTab instead of broad permissions reflect real V3 migration pain points. Heavy on TypeScript patterns and includes testing guidance. If you're building extensions regularly, the categorization alone saves you from relearning the same lessons about alarms API and offscreen documents.
