What it does
Agent skills setup for AntiGravity is the agent-skills-setup-for-antigravity npm package, which sets up a working environment for Google Antigravity inside a project. Installing with a project name creates a GEMINI.md file with agent settings in the root and an .agent folder. That folder holds 16 rules, more than 570 skills and 30 workflows, and shared standards for APIs, databases and security sit in the .shared subfolder. The agent reads these files as the project's long-term memory. Workflows run through the /create, /debug and /audit commands, and the rules set norms for code and context. Maintenance subcommands look after the install itself. Running with a dot instead of a project name fetches missing files, validate checks integrity, and update refreshes the core of the set. The manager subcommand opens a real-time dashboard of the agent swarm.
Who it is for. For developers on Google Antigravity who want to start projects with a shared set of rules and commands for the agent.
Good fit when
- You start a project in Antigravity and want rules, skills and workflows from the first minute
- The agent needs shared standards for APIs, databases and security
- The team wants the same create, debug and audit workflows in every project
- You want to watch the agent swarm on a real-time dashboard
Not a fit when
- You need one small skill: the package installs a whole environment
- You work in Claude Code or Cursor: the set targets Antigravity and Gemini
- The project root already has its own GEMINI.md that must not be overwritten
- The machine has no Node.js: the installer runs through npx
Example request
Install the Antigravity skill set into this project and check that the install is intactLimitations
- The skill count disagrees even on the project page: the table says 575, while the package description and the folder diagram say 573.
- GitHub does not detect the repository license, although the project page names MIT.
- The set is built for Antigravity and Gemini. The author does not describe how it behaves in other agents.
- Playwright is among the package dependencies, so running through npx downloads noticeably more than a set of plain text files.
- Advertised features such as hang detection and self-repair get only one table row each on the project page, with no details on how they work.
How to disable. Delete the .agent folder and the GEMINI.md file from the project. The install writes files only into the project and changes no global settings.
FAQ
How do I install skills for Google Antigravity with one command?
Run `npx agent-skills-setup-for-antigravity my-app` with your own project name. Node.js is required.
How do I restore lost files of the set?
Run the installer with a dot instead of a project name: `npx agent-skills-setup-for-antigravity .`. It checks GEMINI.md and .agent and fetches what is missing.
Can I add my own skills?
Yes. Agents in the set are built from skills, so a new skill only needs to go into .agent/skills as a file. The other route is editing GEMINI.md.
What does Pure Install mean?
Since version 4.1.23 the installer puts only working files into the project, with no internal scripts or dev dependencies.
How is update different from running with a dot?
Running with a dot repairs the current install. The update subcommand refreshes the core of the set and keeps files in the project root and in the .agent folder apart.
