What

Startup computes two decisions about whether this process may forward plugins and hooks to a device. Both admit only for a managed cloud worker, and two new environment variables, CLAUDE_CODE_DISABLE_PLUGIN_FORWARDING and CLAUDE_CODE_DISABLE_HOOK_FORWARDING, each force a refusal.

Details
  • Managed cloud worker means an SDK URL and a remote session id are set, no environment kind is set, the entrypoint is allowlisted, and the run is not hermetic.
  • Refusing plugin forwarding because the environment variable is set logs an event named plugin_forwarding_worker_disabled.
