I'm building Charter: a declarative SDK for agent tools.
Since 2024 I've run agents inside the real Gmail, Calendar, Docs and Sheets of ~280 people. That was SurfBuddy, built solo, and the most fun I've ever had. Charter is the hardened plumbing underneath it, now open sourced: Apache 2.0, no telemetry, no phone home, runs in your process.
