Antigravity: The Sovereign Workspace Agent

Course Overview

Antigravity Arcane Glossary A powerful agentic AI coding assistant designed by Google DeepMind, capable of autonomous reasoning and system interaction. is a powerful agentic AI coding assistant designed by Google DeepMind. In this course, you will learn to wield this agent to solve complex coding tasks, refactor legacy systems, and build whole ecosystems from scratch through Sovereign Command.

⚡ Instant QuickStart: The First Command

Deploy and initialize the agent in 60 seconds.

# 1. Access the Agent
antigravity --help

# 2. Start the Ritual
antigravity "Create a React component for a wizard portal in src/components"

Learning Objectives

• Master the Agentic Mindset: Moving from prompts to high-level goals.
• Leverage System Tools (filesystem, terminal, browser) through the agent.
• Architect complex tasks using the Task Boundary Arcane Glossary Definition not found in Grimoire. logic.
• Verify agent outputs through automated feedback loops.

Technical Deep Dive: The Agentic Loop

Unlike traditional LLMs, Antigravity operates on a Sense – Think – Act loop Arcane Glossary A Sense-Think-Act cycle where an AI agent gathers context, reasons about a goal, and executes tools autonomously. :

1. Sense: Reads files, executes commands, and browses the web to gather context.
2. Think: Reasons about the current state vs. your ultimate goal.
3. Act: Performs multiple tool calls (edits, builds, tests) autonomously until the task is complete.

Walkthrough: The “Refactor Ritual”

Step 1: Context Loading

Before asking for a change, ensure the agent has the depth it needs.

antigravity "Review our existing auth logic in src/lib/auth.ts and propose a more secure pattern in implementation_plan.md"

Step 2: The Sovereign Execution

Once you approve the plan, command the agent to execute across multiple files.

antigravity "Execute the approved Phase 1 in the implementation_plan.md. Run tests after every edit."

Step 3: Verification Logic

Always verify with the agent’s built-in tools.

antigravity "Verify the new auth flow by running the playwright tests in /tests/auth.spec.ts. If they fail, fix the implementation."

Pro Patterns: Task Boundaries

• Plan First: Always ask the agent to create an implementation_plan.md for tasks involving more than 3 files.
• Atomic Commits: Ask the agent to commit changes after every successful verification to keep a clean history.
• Cross-Agent Collaboration: Use Antigravity to build MCP servers that other agents (like Claude) can use.

Capstone Project: The Automated Feature Launch

Use Antigravity to build and deploy a new feature.

1. Command the agent to design a Markdown Blog collection for your Astro site.
2. The agent must create the schema, add 3 sample posts, and build the UI.
3. The agent must verify the build and commit to git.

The machine is no longer a tool; it is a collaborator. Command with wisdom.
