Copilot CLI: Unified configuration with /settings command

GitHub Copilot CLI now has a unified, schema-driven home for configuration. The new /settings slash command combines the scattered commands like /theme, /streamer-mode, and /experimental with options that previously required manually editing your settings file into a single, discoverable surface.

One command, three ways to use it

/settings works whether you want a guided UI, a quick one-liner, or a scripted change in a copilot -p invocation:

• /settings opens a full-screen, sectioned dialog where you can browse and edit every user setting.
• /settings sets a value inline (e.g., /settings autoUpdate true, /settings sessionSync.level full).
• /settings reset restores the default for a setting.

Keys are dotted paths into the CLI’s settings schema, and tab completion surfaces every available key — along with the description and the allowed values for booleans, enums, and enum-or-string unions — right next to your prompt. No more guessing key names or types.

A dialog that fits each setting

Open /settings with no arguments and you get a searchable, alt-screen dialog with editors built for each setting type:

• Boolean toggles, enum pickers, and enum-or-string union pickers.
• Free-form string and number editors, with a multi-line editor for prose.
• Dedicated editors for string and number arrays and generic records.
• A $EDITOR fallback for complex JSON containers. Your settings file is only written after the new value parses and passes schema validation, so a typo can’t silently break your next session.

Press / to search, Ctrl+R to reset the focused setting to its default, and Ctrl+E to open the active settings file in your editor. Setting changes that have side effects (like colorMode or streamerMode) apply live the moment you save, whether you toggled them inline, reset them, or edited the file directly.

Want to jump straight to a specific setting? /settings and /settings reset open the dialog focused on that key.

Get the update

Update GitHub Copilot CLI by running copilot update in your terminal, then run /settings to take it for a spin. Share feedback with the /feedback command in a CLI session, or open an issue in our public repository.
