command not found: ai

I tried following the readme to install this tool. But after installation, I get command not found. I restarted iTerm after installation. Any tips? Thanks!

Start with README.md's installation instructions and the installed package's package.json; verify how the CLI entry point is exposed after npm install -g. Reproduce command lookup in zsh using the reported macOS, Node, and npm versions, and compare the documented command with the package contents. Done means the documented installation makes the `ai` command available in a fresh shell.
