Monitor Unreal Agent with FrontierStack

Unreal Agent is Unreal Labs' open-source, async-first agent harness, written in Go under the MIT licence. Tool calls run in the background, so the model keeps working instead of waiting on each one. It works with OpenAI, Codex, OpenRouter, Fireworks or a local Ollama model. FrontierStack detects the unreal-agent-runner CLI on this Mac or over SSH, and marks hosts where it is running in Agent Operations. The pane installs or updates it with go install and shows which key and provider variables it reads. FrontierStack never runs prompts through it.
