We saw larger tech companies like Ramp (Inspect) and Stripe (Minions) build this internally and thought an open source version should exist.
We made a few very intentional decisions when working on this:
1. Credentials are kept out of the sandbox. Authorized access goes through a proxy, so agents do not directly receive credentials.
2. The harness is not our problem. We're not going to tackle things like memory, self-learning.
3. No magic. Configurations are explicit. You can bring your own keys for models, sandboxes, and other providers. You can write your own instructions and agent.
