At Universe 2025, GitHub handed out Octolamps. Beatris Mendez Gandica wondered: what if hers could show when GitHub Copilot CLI is thinking? Using the native Copilot CLI hooks system, her lamp breathes green when the agent works, turns white when idle, and blinks red on errors via the WLED API. In this GitHub Universe 2026 session, Beatris shows how system-level lifecycle events connect software to physical hardware and how you can build custom hooks for any device. Explore the open-source repository to wire up your own WLED lights.
