Start with Harness
Use Python 3.10 or later in a separate environment from Attune AI. Install the recommended 1.4.0 package:
python -m pip install 'attune-harness[all]==1.4.0'This install adds Redis and Voyage support. Redis use needs a running Redis service; Voyage retrieval needs a Voyage API key and makes paid calls. Integration requirements are covered in the released installation guide.
Installing the Python package does not install an agent plugin or skill. Follow the Quick Start to create an environment, confirm the version and run a small local example before connecting your agent.
