slash/config
Open the Settings interface to adjust theme, model, output style, and other preferences. Pass one or more key=value pairs to set a setting directly without opening the interface, for example /config thinking=false, /config theme=dark, or /config model=sonnet. The key=value form also works in non-interactive mode (-p) and from the Claude mobile app via Remote Control. The key=value form can't turn on a setting that needs your confirmation in the panel, such as autoContinueAtUsageLimit, though it can turn one off. Run /config --help to list the keys it accepts. Alias: /settings

flagtengu_reduce_motion_setting_changed
An analytics event, not a feature flag. Claude Code logs it when the Reduce motion toggle in the settings list is changed, with the field enabled; the change also writes the prefersReducedMotion setting.

Is this right?
