.agents/context.md (Prefix commands section) if not already loaded.app/prefixes/<name>.ts.BasePrefixCommand, decorated with @Prefix, with a PrefixCommandBuilder on data.import { User } from "discord.js";
import { Prefix, BasePrefixCommand, PrefixCommandBuilder, PrefixContext } from "engine";
@Prefix({ cooldown: 3 })
export default class Avatar extends BasePrefixCommand {
data = new PrefixCommandBuilder().setName("avatar").setDescription("Shows a user's avatar.").addAlias("av").addUser("target", "The user to inspect");
async execute(context: PrefixContext) {
const target = context.args.target instanceof User ? context.args.target : context.message.author;
await context.message.reply(target.displayAvatarURL({ size: 1024 }));
}
}
PrefixCommandBuilder deliberately mirrors SlashCommandBuilder naming (camelCase): setName, setDescription, addAlias, and typed addString / addInteger / addNumber / addBoolean / addUser / addMember / addChannel / addRole / addRest.context.args holds resolved typed arguments keyed by name; context.raw has string tokens and context.content the remainder. Also available: prefix, command, globals, permissions.@Prefix accepts cooldown and guilds like slash commands; aliases share the command's cooldown bucket.config.prefix.enabled; the per-guild prefix lives in lib/prefixes.ts.MessageCreate router; engine/prefix_dispatch.ts owns routing.Run bun run typecheck and bun run lint. No deploy step is needed; prefix commands are live on next boot.
