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.

Who uses this skill

The Chrome Ext Best Practices Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
