antigravity-cli
Operate the Antigravity CLI (agy): plugins, auth, sandbox.
Why this skill is useful
Provides specific commands and procedures for operating the Antigravity CLI that the AI wouldn't reliably generate on its own.

What this skill does
Antigravity CLI (agy) Operator guide for the Antigravity CLI, invoked as agy. Run all agy commands through the Hermes terminal tool; inspect its config and logs with readfile. This skill is reference + procedure — it does not wrap a network API, so there is nothing to authenticate from Hermes itself. When to Use Installing, updating, or smoke-testing the agy binary Driving non-interactive agy --print / agy -p one-shots Debugging Antigravity auth, sandbox, permissions, or plugin state Reading Antigravity settings, keybindings, conversations, or logs Mental model Antigravity has two layers — keep them distinct or the guidance will be wrong: 1. Shell wrapper commands — agy help, agy install, agy plugin, agy update, agy changelog. Run these through the terminal tool. 2. Interactive in-session slash commands — /config, /permissions, /skills, /agents, etc. These only exist inside a running agy TUI session, not on the shell wrapper. agy help shows the shell wrapper surface, NOT the in-session slash commands. Prerequisites The agy binary on PATH. Verify through the terminal tool: command -v agy && agy --version. No env vars or API keys required by this skill — Antigravity manages its own auth via the OS keyring / browser sign-in (see Authentication below). How to Run Invoke every agy command through the terminal tool. Examples: For an interactive multi-turn TUI session, launch agy with pty=true (and tmux for capture/monitoring), the same pattern the codex / claude-code skills use. For one-shot smoke tests and scripted prompts, prefer agy --print (non-interactive). To inspect Antigravity's own files, use readfile on the paths under Core paths below — do not cat them through the terminal. Delegation patterns agy is a coding-agent backend in the same family as codex / claude-code, so the same delegation shapes apply. Use these when handing real work (features, fixes, reviews, second opinions) to Antigravity rather than just smoke-testing. …
