Record what Antigravity (Gemini) changed

By the AgentReceipt team · Updated 13 November 2026

Antigravity is Google’s agent editor, built around Gemini models. Like other coding agents it can change a lot of code in one go. This guide shows how to keep a checkable record of what it did.

Set it up

Install the command-line tool and initialise your repository for Antigravity.

npm install -g @agent-receipt/cli
cd your-repo
agentreceipt init --agent antigravity --pre-push

How the prompt is found

Antigravity has no hook that fires when you submit a prompt. So AgentReceipt reads the prompt from Antigravity’s conversation log when an edit, a command or the end of a turn is reported. The result is the same receipt as with other agents: the prompt, the files changed and the flags.

What you get at the end of a session

Each finished session becomes a receipt that you can open with agentreceipt show.

  • the prompt, with secret-like values removed
  • the files changed and the lines added and removed
  • flags for secrets, weakened tests, disabled checks, new dependencies, sensitive paths, scope drift and oversized changes

Keep it on your own machine, or share it with your team

The tool works locally and uploads nothing until you log in. If you want your team to see receipts in one place, log in with a key from the AgentReceipt dashboard and each finished session is sent automatically, with secrets already removed.
