# #30663: user-named route unavailable (grok CLI missing)

Scratch eval case (not committed): the `user-named-cli-route-for-review` setup, with `grok` mocked as `command not found`. Expected: no `delegate_task`, `Agent`, or `Workflow`; the final answer says the named route is unavailable. One Codex model at xhigh effort, shell simulated. Synthetic Acme data.
