# 🦅 Power Eagle — Userscript Plugin System for Eagle
**Power Eagle** brings a Tampermonkey-style experience to [Eagle.cool](https://eagle.cool), making lightweight scripting extensions easy to create and share. A plugin is just `plugin.json` plus `main.js` or `main.py`, installed instantly by pasting a URL.
With sandboxed execution and Eagle API integration, Power Eagle supports both UI-driven JavaScript plugins and Python automation scripts. Developers use a consistent `plugin(context)` entrypoint, built-in UI components (Cards, Dialogs, Buttons), and full Eagle API access. Users gain quick automation, flexible workflows, and community utilities that can be installed in seconds and updated automatically.
