Command prefix
Use the .prefix command (where allowed) to view or set the guild prefix. Defaults to a dot; choose something your members can type reliably.
Command rules
Staff can restrict which commands run in a server via command configuration modules exposed to moderators. Pair this with channel slowmodes or category rules for noisy commands.
Knife Pro features (for example .say, .createembed, .remind, .vanity) require entitlement verification when the bot is linked to the site API.
