Hello, As my colleagues already replied earlier to someone else here, we tried to make this work, but unfortunately hit a hard stop with Anthropic: their current policies do not allow us to support this integration, and we were not able to negotiate an exception

How come I can do this in Zed?

You can actually plug Zed's ACP into Air's acp.json file to draw subscription tokens:

{ "agent_servers": { "Claude Code": { "command": "bunx", "args": ["@zed-industries/claude-code-acp"], "env": {} } } }

Swap bunx with npx -y if necessary
