MIT-licensed Rust tool from Tencent that bridges an AI agent to the real browser you are already signed into, rather than a fresh headless one. A local CLI plus a browser extension let the agent borrow one of your open tabs, drive it using the cookies and sessions you already have, and then return control to you. The effect is that the agent operates inside your existing auth state, so it can reach logged-in pages without a scripted login or credentials handed to a bot.
Most agent-browser tools give the model a blank browser and then you spend the afternoon teaching it to log in. A huge amount of the GTM data an agent actually needs lives behind a login with no clean API — a CRM report view, an ad-account dashboard, a partner portal. BrowserSkill's move is to let the agent ride your existing authenticated session in a tab you choose, which removes the login-automation problem entirely. The same property is the risk: an agent on a borrowed tab can do anything you can do on that site, so this is a lend-one-tab-deliberately tool, not something to point at your whole browser. Used with that discipline, it is the shortest path from "the data is stuck in a logged-in dashboard" to "an agent can read it today."
