Frequently Asked Questions
Common questions about Gemini skills, compatibility, and how to get started.
What are Gemini CLI skills?
Gemini CLI skills are self-contained packages that extend AI coding assistants with specialized expertise. They use the SKILL.md open standard — a markdown file format that defines instructions, workflows, and resources for AI agents. Skills let you teach your AI assistant how to perform specific tasks following your patterns and best practices.
Are Gemini skills free to use?
Yes. All skills listed on GeminiSkill.org are free to use. Most are open-source and hosted on GitHub. You can install them with a simple git clone command into your local skills directory.
What happened to Gemini CLI?
Google announced at I/O 2026 that Gemini CLI would transition to Antigravity CLI for individual users. The open-source codebase remains available, and all skills are compatible with Antigravity CLI by placing them in the .antigravity/skills/ directory instead of .gemini/skills/.
Do skills work with other AI tools besides Gemini?
Yes. The SKILL.md format is an open standard supported by 30+ tools including Antigravity CLI, Claude Code, Cursor, Kiro, GitHub Copilot, and more. Skills are portable — write once, use across any compatible agent.
How do I install a skill?
Clone the skill repository into your agent's skills directory. For Gemini CLI: ~/.gemini/skills/skill-name/. For Antigravity CLI: ~/.antigravity/skills/skill-name/. For project-specific skills, use .gemini/skills/ or .antigravity/skills/ in your project root.
How do I create my own skill?
Create a directory with a SKILL.md file containing your instructions in markdown format. Define when the skill should activate, what it should do, and any examples or constraints. Check our How-To guide for detailed steps.
What is the SKILL.md format?
SKILL.md is an open standard originally published by Anthropic in December 2025, now adopted by 30+ AI coding tools. It is a markdown file with optional YAML frontmatter that packages instructions, workflows, and resources into a portable, version-controlled skill definition.
Is GeminiSkill.org affiliated with Google?
No. GeminiSkill.org is an independent, community-driven directory. We are not affiliated with Google, Anthropic, or any AI tool vendor. We catalog and organize publicly available skills to help developers discover useful tools.
How do I submit a skill to this directory?
Use our Submit page to add your skill. Provide the GitHub repository URL, a description, and relevant tags. Submissions are reviewed for quality before being listed.
What is Antigravity CLI?
Antigravity CLI (command: agy) is Google's next-generation agent platform that replaced Gemini CLI for individual users in June 2026. It is built in Go for performance and retains core Gemini CLI features including Agent Skills, Hooks, Subagents, and Plugins.
