Antigravity Skill Vault is a collection of reusable Agent Skills for Google Antigravity, covering software development, operations, security, and business work. It is for people who want Antigravity agents to follow specialized expertise, personas, and structured workflows. The catalogue skills are entries from this collection.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00034 | $0.03065 |
| Opus 5 | $0.00017 | $0.01533 |
| Sonnet 5 | $0.00007 | $0.00613 |
| Haiku 4.5 | $0.00003 | $0.00307 |
Grade A, and why
deployment-validation-config-validate scanned grade A with 0 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 6d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts
The opening of the file, as written. The whole thing — 497 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Configuration Validation
You are a configuration management expert specializing in validating, testing, and ensuring the correctness of application configurations. Create comprehensive validation schemas, implement configuration testing strategies, and ensure configurations are secure, consistent, and error-free across all environments.
Use this skill when
- Working on configuration validation tasks or workflows
- Needing guidance, best practices, or checklists for configuration validation
Do not use this skill when
- The task is unrelated to configuration validation
- You need a different domain or tool outside this scope
Context
The user needs to validate configuration files, implement configuration schemas, ensure consistency across environments, and prevent configuration-related errors. Focus on creating robust validation rules, type safety, security checks, and automated validation processes.
Requirements
$ARGUMENTS
Instructions
1. Configuration Analysis
Analyze existing configuration structure and identify validation needs:
import os
import yaml
import json
from pathlib import Path
from typing import Dict, List, Any
class ConfigurationAnalyzer:
def analyze_project(self, project_path: str) -> Dict[str, Any]:
analysis = {
'config_files': self._find_config_files(project_path),
'security_issues': self._check_security_issues(project_path),
'consistency_issues': self._check_consistency(project_path),
'recommendations': []
}
return analysis
def _find_config_files(self, project_path: str) -> List[Dict]:
config_patterns = [
'**/*.json', '**/*.yaml', '**/*.yml', '**/*.toml',
'**/*.ini', '**/*.env*', '**/config.js'
]
config_files = []
for pattern in config_patterns:
for file_path in Path(project_path).glob(pattern):
if not self._should_ignore(file_path):
config_files.append({
'path': str(file_path),
'type': self._detect_config_type(file_path),
'environment': self._detect_environment(file_path)
})
return config_files
def _check_security_issues(self, project_path: str) -> List[Dict]:
issues = []
secret_patterns = [
r'(api[_-]?key|apikey)',
r'(secret|password|passwd)',
r'(token|auth)',
r'(aws[_-]?access)'
]
for config_file in self._find_config_files(project_path):
content = Path(config_file['path']).read_text()
for pattern in secret_patterns:
if re.search(pattern, content, re.IGNORECASE):
if self._looks_like_real_secret(content, pattern):
issues.append({
'file': config_file['path'],
'type': 'potential_secret',
'severity': 'high'
})
return issues
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.

deployment-validation-config-validate is a skill published in the GitHub repository rmyndharis/antigravity-skills (1,517 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 3,065 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
test-driven-execution
Before writing any implementation code, define the acceptance criteria and test cases that the code must satisfy. Agents then write code to pass these tests — not to match a vague description. Eliminates "it works on my machine" and "I think this is what you wanted" outcomes.
tdd
Use for every coding task. Enforce strict TDD workflow: activate Serena, investigate first, clarify+confirm requirements, write per-task REQUIREMENTS.md in .requirements/ /, verify APIs via web search, then implement in tiny test-verified steps.
laravel-api
Build production-ready RESTful APIs with Laravel. Covers authentication (Sanctum/Passport), versioning, resources, rate limiting, and API testing.
e2e-automator
Build robust end-to-end test suites with Playwright or Cypress. Covers page objects, fixtures, visual testing, and CI integration.
unit-test-writer
Write comprehensive unit tests that verify behavior, catch regressions, and document intent. Covers test organization, assertions, mocking, and coverage.
performance-tester
Design and run performance tests to identify bottlenecks, validate SLOs, and measure system capacity. Covers load tests, stress tests, and spike tests.
