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