Open Source Chrome Extension Development Skills Package Released
A developer has released an open source package of AI agent skills that encapsulates four years of Chrome extension development experience. The package addresses common pain points like scattered documentation, confusing permissions, debugging across multiple contexts, and unhelpful Web Store rejections.
Skills Included
- Scaffolding with WXT
- Feature development with auto framework detection
- Manifest generation with minimum permissions
- Security auditing
- Testing (with awareness that extensions can't run headless)
- Asset generation
- Publishing with CI/CD
- MV2 to MV3 migration
The security analyzer skill specifically catches issues like innerHTML with untrusted data, missing sender validation, hardcoded API keys, and overly broad permissions—problems that can lead to Web Store rejection or user security compromises.
Compatibility and Installation
The skills work with Claude Code, Cursor, Windsurf, Copilot, Cline, Aider, and any other AI coding tools that support skills. Installation is via:
