📝 Overview
Skills are reusable packages of knowledge that extend what your agent can do. A central SKILL.md file tells the agent what the skill is, when to use it, and how to execute it—so it accomplishes tasks consistently without overwhelming its context window.
🔧 How It Works
The heart of a skill is a single markdown file, SKILL.md:
- SKILL.md is the "brain" of the skill, describing what it is, when to use it, and how to run it.
- SKILL.md is the only required file, but you can bundle additional scripts, examples, and resource directories.
- Skills placed in the global scope (~/.gemini/antigravity/skills/) are available across every project on the machine.
- It suits general utilities like "Format JSON," "Generate UUIDs," or "Review Code Style."
- Writing a small markdown file is enough to turn a common prompt into a reusable, team-shareable command.
🛠 Practical Usage
- Create a code-review skill so the agent checks for bugs, style issues, and best practices when reviewing PRs.
- Capture your team's review procedure in SKILL.md and place it under ~/.gemini/antigravity/skills/ to standardize it.
- Bundle scripts and examples as resources to make the steps concrete.
- Keep project-specific conventions in the workspace scope and general utilities in the global scope.
🎯 Use Cases
- Standardize your team's code-review bar as a code-review skill.
- Make frequent small tasks—JSON formatting, UUID generation—into instantly callable skills.
- Accumulate debugging playbooks as skills so anyone gets the same quality of execution.
- Capture internal conventions and checklists in SKILL.md to onboard new members naturally.
⚠️ Caveats
- Only SKILL.md is required, but if you don't clearly state when to use it, the agent may not fire it appropriately.
- Global-scope skills affect every project, so keep narrowly useful ones in the workspace scope.
- Skills are designed to save context, so scope each one tightly rather than cramming too much in.
