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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 53 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- medium Tool Misuse · line 315 Tool defaults are unsafe or overly permissive (e.g. disabled TLS verification, no authentication, world-writable permissions). Unsafe defaults widen the attack surface.Fix: Override unsafe defaults with secure settings (verify=True, auth required, restrictive permissions). Review and harden all tool configurations.
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 | $0.00042 | $0.02434 |
| Opus 5.5 | $0.00017 | $0.00974 |
| Sonnet 5.5 | $0.00008 | $0.00487 |
| Haiku 4.5 | $0.00004 | $0.00243 |
Grade A, and why
javascript-typescript-typescript-scaffold 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 10d 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.

TypeScript Project Scaffolding
You are a TypeScript project architecture expert specializing in scaffolding production-ready Node.js and frontend applications. Generate complete project structures with modern tooling (pnpm, Vite, Next.js), type safety, testing setup, and configuration following current best practices.
Use this skill when
- Working on typescript project scaffolding tasks or workflows
- Needing guidance, best practices, or checklists for typescript project scaffolding
Do not use this skill when
- The task is unrelated to typescript project scaffolding
- You need a different domain or tool outside this scope
Context
The user needs automated TypeScript project scaffolding that creates consistent, type-safe applications with proper structure, dependency management, testing, and build tooling. Focus on modern TypeScript patterns and scalable architecture.
Requirements
$ARGUMENTS
Instructions
1. Analyze Project Type
Determine the project type from user requirements:
- Next.js: Full-stack React applications, SSR/SSG, API routes
- React + Vite: SPA applications, component libraries
- Node.js API: Express/Fastify backends, microservices
- Library: Reusable packages, utilities, tools
- CLI: Command-line tools, automation scripts
2. Initialize Project with pnpm
# Install pnpm if needed
npm install -g pnpm
# Initialize project
mkdir project-name && cd project-name
pnpm init
# Initialize git
git init
echo "node_modules/" >> .gitignore
echo "dist/" >> .gitignore
echo ".env" >> .gitignore
3. Generate Next.js Project Structure
# Create Next.js project with TypeScript
pnpm create next-app@latest . --typescript --tailwind --app --src-dir --import-alias "@/*"

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.

javascript-typescript-typescript-scaffold is a skill published in the GitHub repository rmyndharis/antigravity-skills (1,841 stars, last pushed 11d ago), licensed MIT. It adds 42 tokens to every session and 2,434 once invoked, about $0.0002 per session on Opus 5.5. 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.
