**Install the Antigravity CLI (`agy`), run `agy plugin install` with the Google Skills repository path, then verify activation with `agy /mcp`—no custom code required.**

The `google/skills` repository provides production-ready conversational skills and MCP (Model Context Protocol) servers for Google Cloud products. Integrating these with the **Antigravity CLI** allows any Antigravity-powered agent to invoke Google APIs conversationally. This guide walks through the exact installation steps, architectural concepts, and verification commands based on the official source.

## Understanding the Integration Architecture

Three components work together to enable zero-code integration:

- **Antigravity CLI (`agy`)** – Discovers, installs, and registers MCP servers. When you run `agy plugin install`, the CLI clones the plugin into `~/.agy/plugins/` and registers its MCP definition with your local agent harness.

- **Google Skills** – Markdown-based skill definitions (e.g., [`SKILL.md`](https://github.com/google/skills/blob/main/SKILL.md) files) that describe prompts, tool usage, and output handling. These are runtime-agnostic; Antigravity interprets their `mcp` metadata to expose underlying APIs.

- **MCP Server** – Each skill optionally ships a small binary or script implementing actual API calls. Antigravity loads these on demand, enabling conversational access to Google Cloud services.

## Step 1: Install the Antigravity CLI

The official installer is a one-line curl command:

```bash
curl -fsSL https://antigravity.google/install.sh | bash

```

Verify successful installation:

```bash
agy version

```

This prerequisite is documented in [`skills/cloud/agent-platform-migrate-from-ai-studio/SKILL.md`](https://github.com/google/skills/blob/main/skills/cloud/agent-platform-migrate-from-ai-studio/SKILL.md), which provides migration guidance from Google AI Studio to Antigravity.

## Step 2: Install a Google Skills Plugin

The generic command format from the repository [`README.md`](https://github.com/google/skills/blob/main/README.md) is:

```bash
agy plugin install https://github.com/google/skills/<plugin-path>

```

### Installing from the Data Agent Kit

The [`plugins/cloud/data-agent-kit/README.md`](https://github.com/google/skills/blob/main/plugins/cloud/data-agent-kit/README.md) lists concrete plugin paths for Google Cloud products. Install individual services as submodules:

```bash

# Spanner

agy plugin install https://github.com/google/skills/plugins/cloud/data-agent-kit/spanner

# BigQuery

agy plugin install https://github.com/google/skills/plugins/cloud/data-agent-kit/bigquery

# AlloyDB

agy plugin install https://github.com/google/skills/plugins/cloud/data-agent-kit/alloydb

```

Each plugin contains a [`SKILL.md`](https://github.com/google/skills/blob/main/SKILL.md) file (e.g., [`plugins/cloud/data-agent-kit/spanner/SKILL.md`](https://github.com/google/skills/blob/main/plugins/cloud/data-agent-kit/spanner/SKILL.md)) defining the conversational skill and MCP metadata for that product.

## Step 3: Verify MCP Activation

Confirm your skill is registered as an MCP tool:

```bash
agy /mcp

```

Expected output shows registered servers:

```text
> agy /mcp
...
spanner   ▶  google-cloud-spanner-mcp  v0.3.5
bigquery  ▶  google-cloud-bigquery-mcp v0.2.1
...

```

Filter for specific tools:

```bash
agy /mcp | grep spanner

```

Detailed verification steps appear in [`skills/ads/google-ads-api-mcp-setup/SKILL.md`](https://github.com/google/skills/blob/main/skills/ads/google-ads-api-mcp-setup/SKILL.md), which documents the `/mcp` endpoint behavior and troubleshooting.

## Using Installed Skills in Antigravity Sessions

Once activated, invoke skills conversationally through the CLI:

```bash
agy ask "List my Spanner databases in project my-project"

```

Antigravity automatically routes the request to the appropriate MCP server—no additional configuration needed.

## Summary

- **Install once**: `curl -fsSL https://antigravity.google/install.sh | bash`
- **Add skills**: `agy plugin install https://github.com/google/skills/<path>`
- **Verify registration**: `agy /mcp` lists active MCP tools
- **Use immediately**: Skills work conversationally via `agy ask` with zero additional code

The integration requires no custom glue code—the Antigravity CLI handles discovery, registration, and execution automatically.

## Frequently Asked Questions

### What is the Antigravity CLI (`agy`) entry point for loading Google Skills?

The `agy` command serves as the unified entry point. It installs skills via `agy plugin install`, verifies them through `agy /mcp`, and invokes them via `agy ask`. According to the `google/skills` source, this three-step workflow requires no custom implementation.

### Do I need to write code to connect Google Skills to Antigravity?

No. The Antigravity CLI automatically clones plugins into `~/.agy/plugins/`, parses their [`SKILL.md`](https://github.com/google/skills/blob/main/SKILL.md) metadata, and registers contained MCP servers. The end-user only runs install and verification commands.

### Where are Google Skills plugin paths documented?

Concrete paths appear in [`plugins/cloud/data-agent-kit/README.md`](https://github.com/google/skills/blob/main/plugins/cloud/data-agent-kit/README.md), which lists submodule directories like `plugins/cloud/data-agent-kit/spanner` and `plugins/cloud/data-agent-kit/bigquery`. The repository root [`README.md`](https://github.com/google/skills/blob/main/README.md) provides the generic command template.

### How do I troubleshoot a skill that doesn't appear in `agy /mcp`?

First confirm successful plugin installation by checking `~/.agy/plugins/` for the cloned repository. Then review the specific skill's [`SKILL.md`](https://github.com/google/skills/blob/main/SKILL.md) file for MCP configuration requirements. The [`skills/ads/google-ads-api-mcp-setup/SKILL.md`](https://github.com/google/skills/blob/main/skills/ads/google-ads-api-mcp-setup/SKILL.md) file contains detailed verification and debugging procedures.
