Installation

Usage
Given configured application options (including storage) and a connection manager:
from microsoft_agents.hosting.core.app import AgentApplication
from microsoft_agents.hosting.core.app.state import TurnState
from microsoft_agents.hosting.slack import SlackAgentExtension, SlackTurnContext
app = AgentApplication[TurnState](options, connection_manager=connections)
slack = SlackAgentExtension(app)
@slack.message()
async def on_slack_message(context: SlackTurnContext, state: TurnState) -> None:
channel_data = context.activity.slack_channel_data
await slack.call(
context,
"chat.postMessage",
{
"channel": channel_data.channel,
"text": f"You said: {context.activity.text}",
},
token=channel_data.api_token or "",
)
Use @slack.message("hello") for a specific message or @slack.event("reaction_added")
for a specific event. Both accept a string, a compiled regular expression, or a list of
either, and match only Slack activities. When called without a selector, they match every
Slack message or event and register at RouteRank.LAST, so more specific routes win.
on_message() and on_event() are deprecated aliases.
@slack.conversation_update(...), @slack.members_added(), @slack.members_removed(),
and @slack.installation_update() mirror the corresponding AgentApplication route
hooks, but match only Slack activities and pass a SlackTurnContext to the handler.
Handlers receive a SlackTurnContext with typed activity.slack_channel_data and
access to the per-turn Slack API client through context.client. Envelope, payload,
and response models support nested lookups such as envelope.get("event.channel")
and typed lookups such as response.get("count", type_=int).
Use slack.create_stream(context, thread_ts=...) to start a SlackStream, then
append content and stop the stream. See the API docstrings for routing options,
client configuration, streaming requirements, and lookup behavior.
