Chrome Ext Best Practices

Category: Engineering  ·  Sub-category: architecture  ·  Last updated:
This skill should be used when working on any Chrome extension project or when the user asks about Chrome extension best practices, conventions, or patterns. Trigger when: setting up a new Chrome extension, configuring WXT, asking about MV3 architecture, "Chrome extension project structure", "WXT config", "extension entrypoints", "manifest v3 setup", "when to use content script vs service worker", "extension context boundaries", "Chrome extension build", "wxt.config.ts", "extension packaging", "Chrome Web Store submission", "cross-browser extension".

From the source SKILL.md

MV3 Chrome extensions operate across multiple isolated contexts with no shared memory. The architecture must respect these boundaries while maintaining clean code organization. WXT is the recommended framework — it provides file-based routing, automatic manifest generation, and Vite-powered builds.

What this skill does

Chrome Ext Best Practices is a community-contributed Claude Code skill in the architecture sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/chrome-ext-best-practices/ and loads when your prompt matches the skill's trigger.
