Usage

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. Set Environment Variables

   export RESEARCH_SLACK_TOKEN=***
   export RESEARCH_SLACK_SIGNING_SECRET=***
   export ANALYST_SLACK_TOKEN=***
   export ANALYST_SLACK_SIGNING_SECRET=***
   export OPENAI_API_KEY=***
   
3. Install Dependencies

   uv pip install 'agno[slack]'
   
4. Run Example

   python multiple_instances.py
   
5. Configure Event Subscriptions

   Set each Slack app’s Event Subscription URL to its prefix:

   @ResearchBot -> https://<your-ngrok-url>/research/events
   @AnalystBot  -> https://<your-ngrok-url>/analyst/events
   

Key Features

• Prefix-Based Routing: Each agent gets its own event path (/research/events, /analyst/events)
• Shared Server: Both agents run on a single AgentOS instance
• Separate Bot Tokens: Each interface uses its own Slack app credentials
• Shared Database: Both agents share the same SQLite database
