# Installation

> Install SuperAntigravity with one command

## Prerequisites

Before installing, make sure you have:

* **[Google Antigravity IDE](https://antigravity.google)** 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:

```bash theme={null}
curl -fsSL https://raw.githubusercontent.com/derHaken/SuperAntigravity/main/install.sh | bash
```

After the script completes, restart Antigravity. Skills, workflows, and agents load automatically — no configuration required.

## What happens during install

<Steps>
  <Step title="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.
  </Step>

  <Step title="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.
  </Step>

  <Step title="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.
  </Step>

  <Step title="Install agents">
    8 specialist agent definitions are copied to
    `~/.gemini/antigravity/agents/`. Agents cover code review, architecture,
    security, research, mentoring, and more.
  </Step>

  <Step title="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.
  </Step>
</Steps>

## Success output

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

```bash theme={null}
[superantigravity] Installing SuperAntigravity...
[superantigravity] Downloading...
[superantigravity] Installing skills...
  ✓ brainstorming
  ✓ writing-plans
  ...
[superantigravity] Installing workflows...
[superantigravity] Installing agents...
[superantigravity] Updating ~/.gemini/GEMINI.md...
[superantigravity] Bootstrap rules added

✓ SuperAntigravity installed!

  19 skills   → ~/.gemini/antigravity/skills/
  16 workflows → ~/.gemini/antigravity/global_workflows/
   6 agents   → ~/.gemini/antigravity/agents/

Restart Antigravity and type /brainstorm to get started.
```

## Install marker file

After a successful install, the script writes a manifest to:

```
~/.gemini/antigravity/.superantigravity-installed
```

This file records the installed version and install date:

```
superantigravity-version=1.0.0
install-date=2026-03-17T00:00:00Z
```

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:

```bash theme={null}
curl -fsSL https://raw.githubusercontent.com/derHaken/SuperAntigravity/main/uninstall.sh | bash
curl -fsSL https://raw.githubusercontent.com/derHaken/SuperAntigravity/main/install.sh | bash
```

The uninstall script removes the `# SuperAntigravity Skills` block from `~/.gemini/GEMINI.md` using the marker, then cleans up the skills, workflows, and agents directories.

<Warning>
  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.
</Warning>
