Multi-Bot Streaming Test
========================

Two agents on the same Slack workspace, mounted on different prefixes.
Both use streaming mode. Tests session isolation: each bot gets its own
DB session even when responding in the same thread.

Setup:
  1. Two Slack apps (Ace + Dash) installed to the same workspace
  2. Event Subscription URLs:
       Ace  -> https://<tunnel>/ace/events
       Dash -> https://<tunnel>/slack/events
  3. Environment variables:
       ACE_SLACK_TOKEN,  ACE_SLACK_SIGNING_SECRET
       DASH_SLACK_TOKEN, DASH_SLACK_SIGNING_SECRET
  4. ngrok: ngrok http --domain=<your-subdomain>.ngrok-free.dev 7777

Slack scopes (per app): app_mentions:read, assistant:write, chat:write, im:history

Run the Example

1. Set up your virtual environment

   Mac

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

   uv venv --python 3.12
   .venv\Scripts\activate
   
2. Install dependencies

   uv pip install -U "agno[os,slack]" openai
   
3. Export environment variables

   Mac/Linux

   export ACE_SLACK_SIGNING_SECRET="your_ace_slack_signing_secret_here"
   export ACE_SLACK_TOKEN="your_ace_slack_token_here"
   export DASH_SLACK_SIGNING_SECRET="your_dash_slack_signing_secret_here"
   export DASH_SLACK_TOKEN="your_dash_slack_token_here"
   export OPENAI_API_KEY="your_openai_api_key_here"
   

   $Env:ACE_SLACK_SIGNING_SECRET="your_ace_slack_signing_secret_here"
   $Env:ACE_SLACK_TOKEN="your_ace_slack_token_here"
   $Env:DASH_SLACK_SIGNING_SECRET="your_dash_slack_signing_secret_here"
   $Env:DASH_SLACK_TOKEN="your_dash_slack_token_here"
   $Env:OPENAI_API_KEY="your_openai_api_key_here"
   
4. Configure Slack

   Complete Slack setup: create and install the app, expose the server through public HTTPS, and add the scopes listed in the example. The default event request URL is <public-url>/slack/events; HITL examples also use <public-url>/slack/interactions for interactivity. Use any custom prefix shown in the example instead of /slack.

5. Run the example

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

   python multi_bot.py
