Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00057 | $0.00712 |
| Opus 5 | $0.00028 | $0.00356 |
| Sonnet 5 | $0.00011 | $0.00142 |
| Haiku 4.5 | $0.00006 | $0.00071 |
Grade C, and why
antigravity-support scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Antigravity CLI Support
This skill provides up-to-date information on how to install, configure, use, and migrate to Antigravity CLI, sourced from the official documentation at https://antigravity.google/docs/cli-getting-started.
What is Antigravity CLI?
Antigravity CLI is a next-generation terminal interface for collaborating with autonomous agents on local codebases. It is designed to be highly interactive and agent-driven, launching a Terminal User Interface (TUI) to coordinate code generation, reasoning, and workspace tasks.
Key Features:
- Autonomous Agent Collaboration: Work directly with agents within your terminal.
- Interactive TUI: A full terminal user interface designed for agent workflows.
- Workspace Integration: Deep understanding of your local workspace structure and context.
Installation
To install the Antigravity CLI on your machine:
macOS / Linux (Fast-Path Script)
Run the following standard curl command in your terminal:
curl -fsSL https://antigravity.google/cli/install.sh | bash
This script downloads, verifies, and installs the latest version of Antigravity,
and automatically registers the agy binary in your PATH.
Windows (PowerShell)
For Windows environments, install via the official PowerShell setup command:
irm https://antigravity.google/cli/install.ps1 | iex
Initial Setup & Configuration
Once installed, navigate to any project or workspace directory and run:
agy
This command starts the Antigravity CLI. The first time you launch it, the interactive TUI will guide you through:
- Workspace Trust Verification: Confirming trust for the workspace folder to allow secure local command execution and file edits.
- Visual Theme Configuration: Setting up your preferred interactive terminal aesthetic and layout.
- Rendering Modes: Tailoring TUI performance and drawing behaviors to your terminal capabilities.
How to Migrate to Antigravity CLI
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

antigravity-support is a skill published in the GitHub repository google-gemini/gemini-cli (106,761 stars, last pushed yesterday), licensed Apache-2.0. It adds 57 tokens to every session and 712 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
