Antigravity Skills Library

A collection of operational skills for AI agents and automation systems. Focused on deterministic execution, safety gates, adversarial review, and structured learning from failure. This repository provides capabilities, not autonomy, policy enforcement, or agent orchestration.

📦 Installation

This library is designed to live within the Antigravity configuration directory.

1. Locate your specific installation directory:

   ~/.gemini/antigravity/skills/
   

2. Clone this repository:

   cd ~/.gemini/antigravity/
   git clone https://github.com/Sounder25/Google-Antigravity-Skills-Library.git skills
   

3. Verify: Ensure the directory structure matches: ~/.gemini/antigravity/skills/00_workspace_forensics/SKILL.md

⚙️ Prerequisites

PowerShell 5.1+ or Core 7+ is required for the underlying automation scripts.

One-time setup for your PowerShell session:

Set-ExecutionPolicy -Scope CurrentUser RemoteSigned -Force
Set-StrictMode -Version Latest
$ErrorActionPreference = "Stop"

🛡️ Robustness & Safety (Gold Standard)

17. Impasse Detector (Self-Correction)

Skill: SKILL-017: Impasse Detector ✅ Verified
Trigger: check logic, am i stuck
detect_impasse.ps1 - Analyzes transcripts for unproductive loops.

18. Pre-Action Guard (QA Gate)

Skill: SKILL-018: Pre-Action Guard ✅ Verified
Trigger: guard check, verify action
guard_check.ps1 - Validates destructive actions against plan.

19. Adversarial Reviewer (Red Team)

Skill: SKILL-019: Adversarial Reviewer ✅ Verified
