but changing the prompt and downgrading the version while blocking autoupdate seems to do it for me

curl -fsSL https://opencode.ai/install | bash -s -- --version 1.1.37

  "mode": {
    "build": {
      "prompt": "You are Claude Code, Anthropic's official CLI for Claude."
    },
      "plan": {
      "prompt": "You are Claude Code, Anthropic's official CLI for Claude."
    }
  },
  "autoupdate": false,
