What problem does it solve? Operating the Antigravity CLI (agy) requires knowing which commands belong to the shell wrapper versus the interactive TUI, how to run non-interactive one-shot prompts, and where to find settings, logs, and plugin state. This Skill provides an operator guide so an agent can install, verify, debug, and delegate work to Antigravity without trial and error. ## Core Features & Use Cases - Wrapper command operations: Install, update, smoke-test, and manage plugins via agy install, agy update, and agy plugin subcommands. - Delegation patterns: Run one-shot prompts with agy -p, background long tasks with completion notifications, drive interactive PTY/tmux sessions, and fan out parallel instances across git worktrees. - Debugging and inspection: Read settings, keybindings, conversation history, and cli-*.log files under ~/.gemini/antigravity-cli/ to diagnose auth, sandbox, and permission issues. - Use Case: Ask the agent to have Antigravity review a diff for bugs using the Gemini 3.1 Pro model, then poll the background process and collect the plain-text result. ## Quick Start Ask the agent to verify the Antigravity CLI installation by running agy --version and agy plugin list through the terminal tool.
