About antigravity.google
Antigravity is a next-generation product platform from Google, designed for developers in the agent-first era. It provides a framework for building and extending agent capabilities through an open standard called Skills. Skills are reusable packages of knowledge that allow agents to perform specific tasks by following instructions, best practices, and conventions defined in a SKILL.md file. The platform supports both workspace-specific and global skills, enabling project-specific workflows as well as personal utilities. Antigravity appears to be part of a broader suite of Google products aimed at developers, with resources including documentation, pricing, and a blog.

FAQ
What is a skill in Antigravity?
A skill is a folder containing a SKILL.md file with instructions that the agent can follow when working on specific tasks. It is an open standard for extending agent capabilities.
Where can I place skills for the agent to use?
Skills can be placed in workspace-specific directories (e.g., .agents/skills/) or global directories (e.g., ~/.gemini/config/skills/). The agent checks these locations based on scope.
Do I need to provide a name for my skill?
The name field in the YAML frontmatter is optional. If not provided, the agent defaults to the folder name as the skill identifier.
Is Antigravity free to use?
The pricing model is listed as free, but exact terms and any limitations should be verified on the official pricing page.
Can I use skills across multiple projects?
Yes, global skills placed in the ~/.gemini/config/skills/ directory are available across all workspaces, while workspace skills are project-specific.
What happens if I have both .agents/skills and .agent/skills directories?
Antigravity defaults to .agents/skills but maintains backward support for .agent/skills. The exact behavior when both exist should be checked in the documentation.
