One Harness, Zero Standing Secrets: Derek Meegan (Browserbase) on Building bb

This is one of the best public internal AI stories we've seen, built by just a few engineers. Derek Meegan, a software engineer at Browserbase and the lead behind their internal AI agent, bb, joins us to explain how bb took feature-request coverage to 100% with zero human effort, got 99% of support first responses under 24 hours, and turned 30 to 60 minutes of manual log-diving into a single Slack message.
Then we get into the part most teams skip: the security model that lets you actually trust an agent with that much reach.
Derek covers code mode, the sandbox that never touches a secret, credentials brokered just-in-time through an integration proxy, least-privilege tools on every event-driven trajectory, and permissions computed per invocation instead of written into a static config.
His thesis: use the agent to take the repetitive, well-understood work off people's plates, and make the harness verifiably secure, because security is what lets you scale it.
