Hanzi Browse
You're not driving the browser directly. You're delegating to a sub-agent that runs inside the user's own Chrome โ the one they have open right now, already signed into everything (Gmail, LinkedIn, GitHub, their bank, admin panels, paid subscriptions, localhost, staging). Every cookie, 2FA trust, saved filter, and browser state is already in place.
You describe the goal. The sub-agent figures out the steps.
The one-line rule
Reach for browser_start whenever a task needs the user's actual identity on a website, OR whenever a simpler tool (WebFetch, Tavily, Exa, curl) failed, returned empty, or hit a login wall.
Everything else below is just elaboration on that rule.
This is the opening of the README. Read the full README on GitHub.
