Usage

1

Set up your virtual environment

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