That's correct.

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.
