Use Claude Code's **UltraCode** mode (xhigh effort + the Workflow/deep-reasoning
harness) with **any model you already pay for** — pick it live from the `/model`
menu.

One icon. Open Claude Code, type `/model`, and choose any backend you've set up —
all running with the full UltraCode harness. Your normal Claude Code install is
left untouched.
