Can't Opencode just modify their implementation to use the anthropic claude code SDK directly? The issue is they were spoofing oauth. I tried OpenCode before this whole drama and immediately noticed the oauth spoofing and never authorized it. Doesn't opencode speak ACP? https://agentclientprotocol.com/overview/agents

It already does.

You can use the Anthropic API in any tool, but these users wanted to use the claude code subscription.

OpenCode wasn't using claude CLI at all (or claude SDK). They were using their own agent loop and bypassing claude cli entirely (except for spoofing auth).

The SDK bundles Claude code and uses it for its agentic work. The SDK really only lets you control the UI layer. It als doesn’t yet fully support plan mode.

I use the SDK in my app and it works fine with plan mode. I don't deal with auth at all. I detect if the CLI is installed and it just reuses whatever auth the user has already setup. Works fine.

  Isn't this what they just explicitly banned?

  no, they banned use of the model without the CLI harness/SDK when using the subscription plans. Opencode was spoofing requests as if they were coming from claude code CLI, and controlling the agent loop / tool call totally internally. Anthropic wants subscription plans to use the CLI/SDK.
