Prerequisites

Before installing, make sure you have:
  • Google Antigravity IDE installed and working
  • git available on your PATH
  • An internet connection (the installer clones from GitHub)

​
Install command

Run this single command in your terminal:
After the script completes, restart Antigravity. Skills, workflows, and agents load automatically — no configuration required.

​
What happens during install

1

Clone the repository

The installer creates a temporary directory and does a shallow clone of the main branch from https://github.com/derHaken/SuperAntigravity. The temporary directory is deleted automatically when the script exits.
2

Install skills

19 skill directories are copied to ~/.gemini/antigravity/skills/. Each skill contains a SKILL.md file that Antigravity reads to trigger the right behavior automatically.
3

Install workflows

16 workflow files are copied to ~/.gemini/antigravity/global_workflows/. These power the slash commands (/brainstorm, /plan, /implement, /review, /git) and other explicit workflow controls.
4

Install agents

8 specialist agent definitions are copied to ~/.gemini/antigravity/agents/. Agents cover code review, architecture, security, research, mentoring, and more.
5

Bootstrap GEMINI.md

The installer appends a # SuperAntigravity Skills block to ~/.gemini/GEMINI.md, creating the file if it does not already exist. This block registers SuperAntigravity with Antigravity’s rules system.

​
Success output

When the install completes successfully, your terminal will show output similar to:

​
Install marker file

After a successful install, the script writes a manifest to:
This file records the installed version and install date:
If this file is present when you run the installer again, you will see a warning that a previous install was detected and that re-running will overwrite existing skills, workflows, and agents.

​
Reinstalling or upgrading

To upgrade to the latest version, uninstall first and then reinstall:
The uninstall script removes the # SuperAntigravity Skills block from ~/.gemini/GEMINI.md using the marker, then cleans up the skills, workflows, and agents directories.
The # SuperAntigravity Skills block cannot be written to GEMINI.md twice. If the marker is already present, the installer skips that step and prints a warning. Run the uninstall script first if you need a clean reinstall.
