Possibly, though at first i was entirely focusing (and still am) on Claude Code usage. Given that CC had an API, i figured its own SDK would update faster/better/etc to new Claude features that Anthropic introduces. I'm sure ACP is a flexible protocol, but nonetheless i was just aiming for direct Claude integration.. and you know, it's an official SDK, seemed quite logical to me.

It would be absurd to me if the same application is somehow allowed via ACP but not via official SDK. Though perhaps the official SDK offers data/features that they don't want you to use for certain scenarios? If that were they case though it would be nice if they actually published a per-SDK-API restrictions list.

That we're having to guess at this feels painful.

edit: Hah, hilariously you're still using the SDK even if you use ACP, since Claude doesn't have ACP support i believe? https://github.com/agentclientprotocol/claude-agent-acp
