Prerequisites

• Python 3.10 or higher
• Poetry installed
• A LaunchDarkly account and SDK key
• API keys for the providers you want to use

Setup

1. Create the following config in your LaunchDarkly project. You can use a different key by setting the environment variable in your .env.

   • Create an AI Agent Config with a model and agent instructions. Default key: sample-agent.

2. Copy .env.example to .env and fill in your keys (only the provider keys for providers you actually use are required):

poetry run agent
