Antigravity Bridge — AI skill for Claude Code

[!CAUTION] **⚠️ Risk Warning — Read Before Use**

This project turns a desktop client into a headless API via CDP injection. This **violates Antigravity's Terms of Service** and carries real risks:

• Account throttling — Rate limits, degraded responses, shadow-banning
• Account ban — Your Google account may be suspended, potentially affecting other Google services (GCP, Workspace, Gmail)
• Detection is trivial — CDP debugger attachment, Security.setIgnoreCertificateErrors, and non-human interaction patterns (zero typing delay, no cursor movement) are all easily detectable

**Protect yourself:**

1. 🚫 Never use your primary Google account — Register a throwaway account
2. 🐢 Add delays between requests — Mimic human typing speed, avoid high concurrency
3. 🧪 Personal research only — Do not use as a production API or multi-user backend
4. 💀 Expect breakage — This is a cat-and-mouse game; the channel can be killed at any time

*Use at your own risk. The authors are not responsible for any account actions taken by Google/Antigravity.*

😡 The Problem

"Opus 4.6 API costs hundreds per month" "Gemini 3.1 Pro is free but has no convenient API" "I want my agent to use multiple models without paying for each"

**Antigravity Bridge** wraps [Antigravity](https://antigravity.com) — a free AI desktop app by Google — into a standard REST API via Chrome DevTools Protocol (CDP). One endpoint, six free models.
