wxtsky/byob — reverse-engineered prompt

Build me a local tool called byob, Bring Your Own Browser, that lets an AI coding assistant use the Chrome browser I already have open. I want it to work with tools like Claude Code, Cursor, Cline, Windsurf, and Codex, so I can ask things like read a logged in page, click around a site, take screenshots, download images, inspect console logs, grab cookies, list tabs, switch tabs, save a page as PDF, or summarize what is on a page.

It should run locally and keep my data on my machine. Please include a Chrome extension, a local bridge, and an MCP server so the AI tool can talk to my real Chrome session. Make setup feel simple, with an install script that checks Node, bun, and Chrome, builds everything, registers the chosen AI tools, and gives clear next steps for loading the extension and restarting Chrome. Add a doctor command that explains what is broken and how to fix it. Look up current docs online if you need to.
