+## What It Does
+
+Antigravity CLI is a new terminal-based coding agent that replaces Gemini CLI. It offers a generous free tier, access to multiple models, and support for subagents, MCP, and Skills.
+
+## Key Strengths
+
+- **Free tier**: Generous free tier with access to Gemini 3.5 Flash, Gemini 3.1 Pro, Gemini 3 Flash, Claude Sonnet 4.6, Claude Opus 4.6, and gpt-oss-120b
+- **MCP support**: Connect external tools
+- **Google ecosystem**: Integrates with Google Cloud services
+- **Large context**: Antigravity's 1M+ token context window
+
+## Best For
+
+- Developers wanting a free terminal agent
+- Google Cloud projects
+- Tasks requiring very large context windows
+
+## Some useful Commands
