Can I think of it as ACP(agent-client-protocol)-over-HTTP? I know ACP is an editor-oriented local protocol, but I think it's similar to the design idea of this project.
As you said – in terms of project goals, the biggest difference is:
- ACP seems to be focused on providing a universal API for the subset of features required for editors
- Sandbox Agent SDK is focused on automating agents, so aims to provide a much more comprehensive API coverage for niche agent-specific features
We maintain a feature coverage matrix (https://sandboxagent.dev/docs/session-transcript-schema#cove...) – it's early, much more coming soon.
