Copilot CLI update: chronicle, plugins, and fleet mode

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.
