Just today I installed the CLI version of antigravity (agy) and have been using it as a headless subagent from within Claude, so uh this works today?

And how do you get this to work exactly? I keep getting variations of "Missing required parameter: redirect_uri" in the OAuth flow.

The solutions proposed by Gemini and Google's AI summaries all hallucinate agy subcommands that don't exist, hilariously.

Edit: after bouncing around several GitHub threads, I realized that the agy TUI framework is wrapping the URL in a way that causes spaces to be inserted where the URL wraps. That's hilarious.

Right above the CLI download link on that page, there's a warning icon with "Authenticate with Antigravity or Antigravity IDE before using the CLI."

Ok, I guess this is outdated then because I did what I said I did.

Ah!

You're right, I just re-tested on my server and was able to get it to work now. Thank you! Does appear to just be stale documentation.
