What is agy-auto and what does it do?

agy-auto is a PreToolUse hook and security harness for Google Antigravity CLI that enables safe unattended execution by passing every pending tool call through a multi-layered policy gate: deterministic hard-deny rules, fast-allow for workspace-scoped and read-only operations, an LLM classifier fallback (Gemini Flash Lite or llama.cpp), and single-use scoped token approvals with Zero Ambient Authority.

When should I use agy-auto?

Use agy-auto when you need unattended execution of Antigravity CLI workflows in CI/CD pipelines, scheduled automation, or long-running agent tasks, especially in environments where you want safe automation without granting blanket permissions.

What LLM options does agy-auto support for policy decisions?

agy-auto supports Gemini Flash Lite or local llama.cpp as LLM classifier fallback options for the policy gate.

When should I NOT use agy-auto?

Do not use agy-auto if you require human review for every single tool invocation, or if your security model prohibits any form of automated approval even with policy constraints.

Why it matters

Enable safe unattended execution of Google Antigravity CLI commands by automatically evaluating every tool call against multi-layered security policies-hard-deny rules, fast-allow for safe operations, LLM classification, and scoped token approvals-without requiring blanket permission skips.

Outcomes

What it gets done

Block dangerous operations through deterministic hard-deny rules

Fast-track workspace-scoped and read-only operations automatically

Classify ambiguous tool calls using LLM fallback (Gemini or local llama.cpp)

Issue single-use scoped tokens with zero ambient authority for approved actions

Overview

agy-auto - Antigravity Auto-Permission & Security Gate

agy-auto is a PreToolUse hook and security harness for Google Antigravity CLI that evaluates every pending tool call through deterministic hard-deny rules, fast-allow rules for workspace-scoped and read-only operations, an LLM classifier fallback (Gemini Flash Lite or local llama.cpp), and single-use scoped token approvals. It enforces Zero Ambient Authority while enabling unattended execution without `--dangerously-skip-permissions`. agy-auto is a PreToolUse hook for Google Antigravity CLI that provides an alternative to `--dangerously-skip-permissions` by passing tool calls through multi-layered policy gates with Zero Ambient Authority.

What it does

agy-auto is a PreToolUse hook and security harness for Google Antigravity CLI (agy) that enables safe unattended execution without relying on --dangerously-skip-permissions. It passes every pending tool call through a multi-layered policy gate: deterministic hard-deny rules, deterministic fast-allow for workspace-scoped and read-only operations, an LLM classifier fallback (Gemini Flash Lite or local llama.cpp), and single-use scoped token approvals with Zero Ambient Authority.

When to use - and when NOT to

agy-auto is a PreToolUse hook for Google Antigravity CLI that provides an alternative to --dangerously-skip-permissions by evaluating tool calls through policy gates.

Inputs and outputs

The user provides agy-auto as a PreToolUse hook to the Antigravity CLI. Each pending tool call is evaluated against the configured policy layers: hard-deny rules, fast-allow rules for workspace-scoped and read-only operations, and an optional LLM classifier (Gemini Flash Lite or local llama.cpp).

Integrations

agy-auto integrates with Google Antigravity CLI (agy) as a PreToolUse hook. The LLM classifier fallback can use Gemini Flash Lite or local llama.cpp.

Who it's for

agy-auto is for users who need to run Antigravity CLI without relying on --dangerously-skip-permissions and want multi-layered policy evaluation of tool calls with Zero Ambient Authority.
