Using agent-skills with Antigravity CLI (agy)
The agent-skills package can be installed as a native plugin in the Antigravity CLI (agy), giving the agent access to structured workflows, personas, and custom slash commands.
Setup
Option 1: Native Plugin Installation (Recommended)
Antigravity CLI has a first-class plugin system that registers skills, agents, and custom commands.
Install from a local clone:
- Clone the repository:
git clone https://github.com/addyosmani/agent-skills.git - Install the plugin using
agy:agy plugin install /path/to/agent-skills
This will validate the plugin and install it into your global Antigravity configuration directory (~/.gemini/antigravity-cli/plugins/agent-skills/).
Option 2: Import from Gemini CLI
If you have already installed agent-skills under your legacy Gemini CLI installation, you can import it directly:
agy plugin import gemini
Once installed, verify the active plugin:
agy plugin list
Slash Commands
The plugin registers 7 custom slash commands that map to the development lifecycle:
| Command | What it does | Activated Skill |
|---|---|---|
/spec |
Write a structured spec before writing code | spec-driven-development |
/planning |
Break work into small, verifiable tasks | planning-and-task-breakdown |
/build |
Implement the next task incrementally | incremental-implementation |
/test |
Run TDD workflow — red, green, refactor | test-driven-development |
/review |
Five-axis code review | code-review-and-quality |
/code-simplify |
Reduce complexity without changing behavior | code-simplification |
/ship |
Pre-launch checklist via parallel persona fan-out | shipping-and-launch |
Each command automatically invokes the corresponding skill and guides the agent step-by-step.
Note: Use
/planninginstead of/planto avoid conflicts with Antigravity's internal plan-generation command.
Skills & Discovery
Antigravity automatically discovers skills inside the plugin's skills/ directory.
- Antigravity matches user tasks and intents to relevant skills on-demand.
- If a task matches a skill, the agent will load the skill and prompt you for permission before executing.
Verification & Validation
To validate that your local plugin is correctly structured and contains all skills, run:
agy plugin validate /path/to/agent-skills
