What's Wrong?

The /design-sync slash command is not available in my Claude Code installation. When I type /design-sync, it is not recognized as a valid command and does not appear in the slash command list (autocomplete). I'm running version 2.1.195. Based on the documentation and other references, I expected this command to be present, but it does not exist in my setup.

What Should Happen?

The /design-sync command should be available and recognized when typed, and it should appear in the slash command autocomplete list so it can be run successfully.

      Expected: the /design-sync command is listed and runnable.

Same error in v2.1.196 MacOS. Solution was to remove CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC from env in claude settings.json

Specifically it should be unset due to a faulty falsey conditional:

"CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "",
