If you run ag auth and you get the error: CLI authentication failed or your CLI gets stuck on 
Waiting for a response from browser...
It means that your CLI was not able to authenticate with your Agno account on app.agno.com The quickest fix for this is to export your AGNO_API_KEY environment variable. You can do this by running the following command: 
export AGNO_API_KEY=<your_api_key>
Your API key can be found on app.agno.com in the sidebar under API Key. agno-api-key Reason for CLI authentication failure:
  • Some browsers like Safari and Brave block connection to the localhost domain. Browsers like Chrome work great with ag setup.
