The framework. void_agent-*-py3-none-any.whl is pure Python and installs anywhere. Extras go in brackets: pip install "void-agent[openai,mcp] @ <wheel url>".
The terminal UI. void-agent-cli-* is one binary per platform — the UI, the agents, the MCP SDK and ripgrep inside. No Python, nothing to install: download the one for your machine, chmod +x, run it. macOS asks once the first time (right-click → Open, or xattr -d com.apple.quarantine).
