Getting Started

  1. Download the Arena CLI
  2. Extract the archive
   tar xzf arena-cli-latest.tar.gz
  1. Install — requires uv, the install script creates a Python 3.13+ venv automatically
   ./install.sh
  1. Verify the install
   ~/.arena/bin/arena --help
  1. Add to PATH — for direct arena command access
   echo 'export PATH="$HOME/.arena/bin:$PATH"' >> ~/.zshrc
   source ~/.zshrc
  1. Authenticate
   arena auth login
  1. Run arena init to pull the starting template for Challenge 0: Grounded Reasoning

Auto-updates are built in — the CLI checks for new versions on every command. Disable with export ARENA_NO_AUTO_UPDATE=1.

1. Challenge 0

The first Arena Challenge uses the OfficeQA benchmark by Databricks — a grounded reasoning challenge over U.S. Treasury Bulletin documents spanning 1939–2025.
