Mount Multiple Slack Bots
=========================

Serve a research bot and an analysis bot from one AgentOS. Each Slack app has
its own credentials, URL prefix, identity, and entity-scoped thread sessions.

Run: .venvs/demo/bin/python cookbook/05_agent_os/17_slack/multiple_bots.py
Try in Slack: Ask the research bot for sources, then ask the analyst bot for a brief
Slack scopes: app_mentions:read, assistant:write, chat:write, im:history (per app)

Run the Example

Set up your virtual environment

uv venv --python 3.12
source .venv/bin/activate

Prepare the Slack app

Follow Slack setup to create and install the app, obtain its bot token and signing secret, and configure its current agent experience. Add the bot scopes listed in this example's source docstring and reinstall after changing scopes. Subscribe to app_mention and message.im; configure interactivity for buttons and forms.

Install ngrok and run ngrok http 7777 in another terminal. Keep the tunnel running. After starting this example's server, use the callback paths listed on this page under your public HTTPS URL and complete Slack's verification challenge. Configure each app separately for a multi-app example.

Streaming requires the corresponding Slack app capability. The current Agno adapter initializes suggested prompts on the legacy assistant_thread_started event; the setup guide explains the new-app limitation. Keep only one standalone example on port 7777 at a time.

Install dependencies

uv pip install -U "agno[os,slack]" ddgs openai

Export your OpenAI API key

export OPENAI_API_KEY="your_openai_api_key_here"
export RESEARCH_SLACK_TOKEN="your_research_slack_token_here"
export RESEARCH_SLACK_SIGNING_SECRET="your_research_slack_signing_secret_here"
export ANALYST_SLACK_TOKEN="your_analyst_slack_token_here"
export ANALYST_SLACK_SIGNING_SECRET="your_analyst_slack_signing_secret_here"

Run the example

Save the code above as multiple_bots.py, then run:

python multiple_bots.py

Connect Slack to the running server

Keep Python and ngrok running. In each app's Slack settings, prepend your public HTTPS origin to these paths:

AppEvent subscriptionsInteractivity
Research app/research/events/research/interactions
Analyst app/analyst/events/analyst/interactions

Complete URL verification, then send a DM or invite the app to a channel and @mention it. Ordinary channel replies require an @mention with the default configuration.
