Prototyping UI Toolkit with Unity CLI

Learn how to prototype a game UI using Unity UI Toolkit and an AI agent directly through the Unity CLI! In this tutorial, we start from concept art and a short brief, and watch an AI agent build a fully functional main menu inside the Unity Editor - all driven from the terminal. What you’ll learn: ✔️ The agent brief workflow: How to brief, guide, and steer an AI agent as it builds UI screens from concept art. ✔️ Under the hood: How the Pipeline package, official Unity agent skills, and custom CLI commands work together. ✔️ Automated feedback loops: How to run Play mode UI tests and capture Game view screenshots via the command line so the agent can inspect, verify, and iterate on its own work. ✔️ The core agent loop: Master the Observe ➔ Perceive ➔ Plan ➔ Act cycle to successfully delegate complex tasks while retaining full control over the output.
