AG Kit is a toolkit that gives Google Antigravity coding agents a structured workspace with rules, skills, specialist agents, workflows, persistent memory, orchestration, MCP guidance, and a safety hook. It is for building and operating agent workflows in Antigravity, and its catalogue entries provide parts of that workspace contract.
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.

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 | $0.00027 | $0.00431 |
| Opus 5 | $0.00014 | $0.00216 |
| Sonnet 5 | $0.00005 | $0.00086 |
| Haiku 4.5 | $0.00003 | $0.00043 |
Grade A, and why
templates 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 5d 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.
This is a copy
92% identical to templates — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Project Templates
Quick-start templates for scaffolding new projects.
🎯 Selective Reading Rule
Read ONLY the template matching user's project type!
| Template | Tech Stack | When to Use |
|---|---|---|
| nextjs-fullstack | Next.js + Prisma | Full-stack web app |
| nextjs-saas | Next.js + Stripe | SaaS product |
| nextjs-static | Next.js + Framer | Landing page |
| nuxt-app | Nuxt 4 + Pinia | Vue full-stack app |
| express-api | Express + JWT | REST API |
| python-fastapi | FastAPI | Python API |
| react-native-app | Expo + Zustand | Mobile app |
| flutter-app | Flutter + Riverpod | Cross-platform |
| electron-desktop | Electron + React | Desktop app |
| chrome-extension | Chrome MV3 | Browser extension |
| cli-tool | Node.js + Commander | CLI app |
| monorepo-turborepo | Turborepo + pnpm | Monorepo |
| astro-static | Astro + MDX | Blog / Docs |
Usage
- User says "create [type] app"
- Match to appropriate template
- Read ONLY that template's TEMPLATE.md
- Follow its tech stack and structure
What ships with it
13 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

templates is a skill published in the GitHub repository vudovn/ag-kit (8,168 stars, last pushed 4d ago), licensed MIT. It adds 27 tokens to every session and 431 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to templates, differing in 3 lines, and is treated as a copy.
