/config

Opens the settings interface for theme, model, output style, and other preferences.

Opens the settings interface for theme, model, output style, and other preferences. From v2.1.181 it can be set directly with key=value (e.g. /config thinking=false); from v2.1.182 named shortcuts are available (/config theme=dark, /config model=sonnet). key=value also works non-interactively (-p) and via Remote Control. '/config --help' lists all keys. Alias: /settings.

✅ WHEN TO USE IT?

Set a single known value directly via command

/config theme=dark or /config model=sonnet

Browse interactively through all settings when unsure what to change

/config with no argument opens the settings UI

⛔ WHEN NOT TO?

Expecting the interactive dialog to work in a non-interactive script

the interactive UI isn't suited for automated/non-interactive (-p) runs

Better: use /config key=value directly — it also works non-interactive and via Remote Control
