## Summary
A specialized Agent Skill for AI coding agents that enables them to build, debug, and publish cross-browser extensions for Chrome, Edge, Firefox, Safari, and other Chromium- or Gecko-based browsers using the open Agent Skills format.

## Key Features
- Provides structured guidance for AI agents to build cross-browser extensions with a single codebase
- Integrates with MCP servers for live browser inspection, debugging, and publishing
- Includes progressive-disclosure references for modular learning (templates, project structure, API gotchas)
- Enforces accuracy through verified framework facts and test suites against Extension.js
- Supports multiple AI agents (Claude Code, Cursor, GitHub Copilot, etc.) via open Agent Skills format

## Why It Matters for RAG Builders
It enables AI agents to reliably build and debug cross-browser extensions, reducing manual effort and improving accuracy in extension development workflows.
