defineChannelCommand - Copilotkit

defineChannelCommand preserves a command definition and infers structured options when the provider supplies them.

Signature

function defineChannelCommand<Schema extends ObjectSchema>(
  command: ChannelCommand<Schema>,
): ChannelCommand<Schema>;

interface ChannelCommand<Schema extends ObjectSchema> {
  name: string;
  description?: string;
  options?: Schema;
  handler(
    context: CommandContext<InferSchemaOutput<Schema>>,
  ): void | Promise<void>;
}

Example

import { defineChannelCommand } from "@copilotkit/channels";

export const triage = defineChannelCommand({
  name: "triage",
  description: "Triage the current conversation.",
  async handler({ thread, text, user, platform }) {
    await thread.runAgent({
      prompt: text || "Triage this conversation.",
      context: [
        { description: "Provider", value: platform },
        {
          description: "Invoking user",
          value: user?.name ?? user?.id ?? "unknown",
        },
      ],
    });
  },
});

Managed Slack and Teams do not dispatch commands: leading-slash content remains a normal message. This API applies when a developer-owned direct adapter emits an IncomingCommand.

CommandContext

`options`	`TOptions`	Structured options when the adapter supplies them.
`user`	`ApplicationUser \| null`	Application user selected by `identifyUser`.
