GitHub Copilot CLI now offers slash commands—built-in controls that let you switch AI models, manage token usage, resume past work sessions, and inspect code changes without leaving the terminal.

What happened: GitHub has documented slash commands for Copilot CLI, a terminal-based interface to the AI assistant. Users can type commands like /model to switch between different AI models, /context to check token usage, /resume to pick up past sessions, /diff to review recent code changes, and /reset-allowed-tools to manage file-editing permissions.

Why it matters: Developers using Copilot CLI can now control the assistant's behavior and stay aware of resource limits without interrupting their workflow. The /model command lets users pick models optimized for different tasks—some for quick refactoring, others for deeper reasoning—and see cost multipliers to balance performance against usage limits.

What to watch: The article notes that different models have varying capabilities and availability depending on your plan or organization's settings, and that Copilot CLI will automatically compact conversations when approaching token limits, though users can also do this manually with the /compact command.
