GitHub Checkout
In this episode of GitHub Checkout, we sit down with Copilot CLI Product Manager Ryan Hecht to explore the latest experimental features. We cover the plugin marketplace, the /chronicle slash command for self-healing prompts, and how to run Claude Opus 4.6, GPT-5.4, and Gemini 3 simultaneously. We also walk through how /fleet mode and autopilot can handle massive refactoring tasks while you step away.
