Class: SlackChannelAdapter

Defined in: packages/agentos/src/io/channels/adapters/SlackChannelAdapter.ts:73

Channel adapter for Slack using the @slack/bolt SDK.

Uses dynamic import so @slack/bolt is only required at runtime when the adapter is actually initialized.

When appToken is provided, the adapter uses Socket Mode (no public endpoint required). Otherwise, it starts an HTTP server for receiving Slack events.

Capabilities: text, rich_text, images, documents, reactions, threads, mentions, buttons, group_chat, channels, editing, deletion.

doConnect()

protected doConnect(auth): Promise<void>

Defined in: packages/agentos/src/io/channels/adapters/SlackChannelAdapter.ts:103

Establish the platform connection using the supplied credentials. Called by initialize after state has been set to connecting. Must throw on failure — the base class handles retry and state changes.

Parameters

ChannelAuthConfig & object

Returns

Promise<void>

Overrides

BaseChannelAdapter.doConnect

---

doSendMessage()

protected doSendMessage(conversationId, content): Promise<ChannelSendResult>

Defined in: packages/agentos/src/io/channels/adapters/SlackChannelAdapter.ts:177

Deliver a message to the external platform. Called by sendMessage only when the adapter is connected.

Parameters

conversationId

string

content

MessageContent

Returns

Promise<ChannelSendResult>

Overrides

BaseChannelAdapter.doSendMessage

---

doShutdown()

protected doShutdown(): Promise<void>

Defined in: packages/agentos/src/io/channels/adapters/SlackChannelAdapter.ts:198

Release platform resources (close WebSocket, stop polling, etc.). Called by shutdown before the state transitions to disconnected.

Returns

Promise<void>

Overrides

BaseChannelAdapter.doShutdown

---

editMessage()
