Overview

The Antigravity CLI (agy) is a terminal-native AI agent designed for developers who prefer command-line workflows. It allows you to run high-level natural language instructions against any codebase, executing multi-file edits, running shell commands, executing automated test suites, and orchestrating complex background tasks.

For static website creators, agy streamlines tasks like batch image optimization, HTML SEO meta tag audits, asset reorganizations, and static site generator builds without leaving your shell.

Key Highlights & Features

• Terminal-First Workflow: Run interactive sessions or one-shot commands directly inside PowerShell, Bash, or Zsh.
• Slash Commands: Quick shortcuts like /plan (step-by-step roadmaps), /goal (deep long-running execution), and /grill-me (interactive interview to finalize specs).
• Customization Ecosystem: Native loading of workspace skills, project rules (.agents/), hooks, and Model Context Protocol (MCP) servers.
• Headless Task Execution: Ideal for CI/CD pipelines, git hook automation, and automated repository maintenance.
• Full Shell Integration: Safely runs commands, monitors dev servers, and parses build outputs autonomously.
