This repository contains a collection of example Skills for Google Antigravity. These examples demonstrate the "Agentic Command Line" concept, showing how to package expertise, workflows, and tools into modular units that an AI agent can use.

Antigravity Skills allow you to define how an agent should behave, what tools it should use, and what context it should reference. This project breaks down skill development into 5 levels of complexity.

The skills_tutorial/ directory contains the following examples:

git-commit-formatter

• Concept: Pure Prompt Engineering.
• Function: Intercepts "commit" requests and formats the message according to the Conventional Commits specification.
• Key File: SKILL.md

license-header-adder

• Concept: Loading static resources.
• Function: Adds a standard Apache 2.0 license header to source files by reading a template from the resources/ folder.
• Key Files: SKILL.md, resources/HEADER_TEMPLATE.txt

json-to-pydantic

• Concept: Learning by Example.
• Function: Converts JSON data into Pydantic models by referencing a "Golden Example" pair (Input JSON -> Output Python) instead of using complex instructions.
• Key Files: SKILL.md, examples/

database-schema-validator

• Concept: Delegating to deterministic scripts.
• Function: Validates SQL schema files for safety and naming conventions by running a Python script, ensuring 100% accuracy.
• Key Files: SKILL.md, scripts/validate_schema.py

adk-tool-scaffold

• Concept: Combining scripts, templates, and examples.
• Function: Orchestrates a full workflow to scaffold a new Antigravity ADK Tool. It generates the file using a script, populates it from a Jinja2 template, and guides the implementation using a reference example.
• Key Files: SKILL.md, scripts/scaffold_tool.py, resources/ToolTemplate.py.hbs, examples/WeatherTool.py

To use these skills in your Antigravity environment:

1. Clone this repository.
2. Copy the desired folders from skills_tutorial/ into your workspace's .agent/skills/ directory (or your global ~/.gemini/antigravity/skills/ directory).
3. Restart your agent session.
