# Antigravity Code Review

Review current code changes by delegating to the `antigravity-reviewer` agent — a subscription-backed second opinion via Google's Antigravity CLI (`agy`).

## Prerequisites

This skill is **experimental** and requires:

- `agy` installed and **logged in once** (run `agy` interactively to complete Google Sign-In).

- - The Antigravity MCP server registered, e.g. `claude mcp add antigravity -- npx -y ask-antigravity-mcp`.

+ - The Antigravity MCP server registered, e.g. `claude mcp add antigravity -- npx -y @ask-llm/antigravity-mcp`.

It is one-shot (no multi-turn) and **subscription-backed** — it uses your Google AI Pro/Ultra plan, not per-token API billing. For routine review on a paid OpenAI/Gemini setup, prefer [`codex-review`](../codex-review/SKILL.md) or [`gemini-review`](../gemini-review/SKILL.md). To compare several providers at once, use [`multi-review`](../multi-review/SKILL.md).

## Instructions

1. Gather the diff to review:

- Run `git diff` to get unstaged changes

- Run `git diff --cached` to get staged changes

- Combine both into a single diff

2. If the diff is empty, inform the user there are no changes to review.

3. Launch the `antigravity-reviewer` agent with the diff content. The agent handles the Antigravity prompt structure, confidence filtering, and output formatting. If the `mcp__antigravity__ask-antigravity` tool is unavailable, the agent will tell the user to register the Antigravity MCP server rather than failing silently.
