Installation

Antigravity Kit can be installed using npm or npx. The installation process adds the .agent folder containing all templates to your project.

​
Installation Methods

​
What Gets Installed

The installation creates a .agent folder in your project with the following structure: 
.agent/
├── ARCHITECTURE.md          # System documentation
├── agents/                  # 20 Specialist Agents
│   ├── frontend-specialist.md
│   ├── backend-specialist.md
│   ├── database-architect.md
│   ├── security-auditor.md
│   ├── debugger.md
│   └── ... (15 more)
├── skills/                  # 37 Skills
│   ├── react-best-practices/
│   ├── api-patterns/
│   ├── database-design/
│   ├── testing-patterns/
│   └── ... (33 more)
├── workflows/               # 11 Slash Commands
│   ├── brainstorm.md
│   ├── create.md
│   ├── debug.md
│   ├── deploy.md
│   └── ... (7 more)
├── rules/                   # Global Rules
└── scripts/                 # Master Validation Scripts
    ├── checklist.py
    └── verify_all.py

​
Installation Options

The ag-kit init command supports several options: 
ag-kit init --force

​
Important: .gitignore Configuration

If you are using AI-powered editors like Cursor or Windsurf, adding the .agent/ folder to your .gitignore may prevent the IDE from indexing the workflows. This results in slash commands (like /plan, /debug) not appearing in the chat suggestion dropdown.
To keep the .agent/ folder local (not tracked by Git) while maintaining AI functionality:
1

Remove from .gitignore

Ensure .agent/ is NOT in your project’s .gitignore file.
2

Add to local exclude

Instead, add it to your local exclude file:
echo ".agent/" >> .git/info/exclude
This keeps the folder local without affecting other team members or requiring changes to the shared .gitignore.
The .git/info/exclude file works like .gitignore but is local to your repository clone and not shared with others.

​
Updating Antigravity Kit

To update to the latest version: 
ag-kit update
The update command pulls the latest templates from the repository and overwrites your .agent folder.

​
