[0:00] Antigravity CLI
In a few minutes, Antigravity CLI will be working in your project folder, and you'll know how to keep it in check.
AI for Research Efficiency. Episode 2.3: Install Antigravity CLI.
Last time: a terminal, a project folder, Git and Python, and an account.
In this episode: install Antigravity CLI, sign in, run it in your project folder, and check each step before you speed up.

[0:33] Install
Step one: in PowerShell, paste this line. It's irm, then Google's installer address at antigravity.google, then a vertical bar, and iex.
On a Mac, use the second line, in Terminal. Both lines are on the companion page.

[0:57] Check the version
Step two: close the terminal, open a new one, and type agy --version. You should see a version number.
If it says agy is not recognized, the terminal hasn't found it yet. Open a new one, and try again.

[1:19] Start in your folder
Step three: go into your project folder with cd agent-work, and type agy.
Always start it in a project folder, never in your home folder.

[1:36] Sign in
Step four: the first time, Antigravity opens your browser to sign in with your Google account. Next time, it signs you in on its own.
Individuals can use it free, within weekly limits. Google AI Pro and Ultra plans raise them.

[1:55] Check each step
Step five: Antigravity starts in its default mode. Before it changes a file, it shows you the change, and waits for you to press y.
And on Windows, it asks before every command.

[2:09] A first question
Step six: ask it something. What's in this folder?
It looks through the files, and answers in plain words.

[2:24] Speed up
Step seven: when you trust it with a task, press Shift and Tab for accept edits mode, and allow the commands you trust with slash permissions. The work goes much faster.
Google's own advice: monitor and verify all actions taken by the agent.

[2:45] Try it
Pause now: install Antigravity CLI, open a new terminal, and check the version.

[2:57] Review and next
So: one line to install, a new terminal, your project folder, sign in with Google, default mode first, then accept edits when you trust it.
Next: a worked example. Agents read a whole literature folder in parallel, and check every claim.
