google-antigravity

google-antigravity is an agent for coding agents from qidu/model_proxy_v3. It costs 0 tokens per session (2,410 once invoked), scanned B, original, no licence file.

A Python software development kit for building AI agents powered by Google's Antigravity and Gemini systems.

In plain words
What is it for?
Use it to build agents with secure, stateful execution through the Antigravity and Gemini platforms.
Why use it?
It provides the infrastructure for the agent loop, state, and security so developers can focus on the agent's task.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

google-antigravity scanned grade B with 1 finding 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 3d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

`capabilities=CapabilitiesConfig()` to enable all tools (including writes).

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.

google-antigravity is an agent published in the GitHub repository qidu/model_proxy_v3 (1 stars, last pushed 3d ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 2,410 tokens. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
