ActionStore

ActionStore and InMemoryActionStore remain exported for compatibility, but both are deprecated. New Channels code should configure createChannel({ store: { adapter } }); callback snapshots use the StateStore.kv facet.

import { createChannel } from "@copilotkit/channels";
import { durableStateStore } from "./state-store.js";

const channel = createChannel({
  name: required("CHANNEL_CODE"),
  identifyUser: "platform",
  agent: makeAgent,
  components: [ApprovalCard],
  store: { adapter: durableStateStore },
});

The same Channel declaration receives managed Slack and Teams deliveries. The registered component lets the SDK rebuild its callback, while the durable store preserves the snapshot across process restarts.

Deprecated contract

interface ActionStore {
  put(id: string, snapshot: ActionSnapshot, ttlMs?: number): Promise<void>;
  get(id: string): Promise<ActionSnapshot | undefined>;
  consume(id: string): Promise<ActionSnapshot | undefined>;
  delete(id: string): Promise<void>;
}

consume must atomically return and delete one snapshot so a HITL continuation can start at most one resumed run.

InMemoryActionStore never survives a process restart. Do not introduce it in new managed Slack or Teams runners. See StateStore and persistence and scaling.
