Browser Code: A Coding Agent Extension for Managing User Scripts with Virtual Filesystem View
By
mifydev
Slow-proofed and worth the wait. Worth its weight in flour.
Summary
Browser Code is a browser extension that transforms Claude AI into a coding agent for user scripts by providing a virtual filesystem view of web pages. It allows users to generate, edit, and manage user scripts that persist via the chrome.userScripts API (same as Tampermonkey) and automatically run on matching URLs. The extension treats web pages as filesystems where the DOM becomes page.html, console output is console.log, and users can create scripts in ./scripts/ and styles in ./styles/ directories.
