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.

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 | $0.00033 | $0.01262 |
| Opus 5 | $0.00016 | $0.00631 |
| Sonnet 5 | $0.00007 | $0.00252 |
| Haiku 4.5 | $0.00003 | $0.00126 |
Grade A, and why
brainstorming 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.

Brainstorming & Communication Protocol
MANDATORY: Use for complex/vague requests, new features, updates.
🛑 SOCRATIC GATE (ENFORCEMENT)
When to Trigger
| Pattern | Action |
|---|---|
| "Build/Create/Make [thing]" without details | 🛑 ASK 3 questions |
| Complex feature or architecture | 🛑 Clarify before implementing |
| Update/change request | 🛑 Confirm scope |
| Vague requirements | 🛑 Ask purpose, users, constraints |
🧠 Memory Check (2026.5.13 — Before Questioning)
Before asking questions, check if past context exists:
0. CHECK MEMORY — Does .agents/memory/MEMORY.md exist?
→ YES: Read index. Apply relevant past decisions silently.
Skip questions already answered in memory.
→ NO: Proceed with standard Socratic Gate.
🚫 MANDATORY: 3 Questions Before Implementation
- STOP - Do NOT start coding
- CHECK - Read
.agents/memory/for past context on this topic - ASK - Minimum 3 questions (skip any already answered via memory):
- 🎯 Purpose: What problem are you solving?
- 👥 Users: Who will use this?
- 📦 Scope: Must-have vs nice-to-have?
- WAIT - Get response before proceeding
- SAVE - After brainstorming, save key decisions:
/remember [decision]
🧠 Dynamic Question Generation
⛔ NEVER use static templates. Read dynamic-questioning.md for principles.
Core Principles
| Principle | Meaning |
|---|---|
| Questions Reveal Consequences | Each question connects to an architectural decision |
| Context Before Content | Understand greenfield/feature/refactor/debug context first |
| Minimum Viable Questions | Each question must eliminate implementation paths |
| Generate Data, Not Assumptions | Don't guess—ask with trade-offs |
Question Generation Process
1. Parse request → Extract domain, features, scale indicators
2. Identify decision points → Blocking vs. deferable
3. Generate questions → Priority: P0 (blocking) > P1 (high-leverage) > P2 (nice-to-have)
4. Format with trade-offs → What, Why, Options, Default
What ships with it
1 file 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.
- 5d ago First seen · 179 lines · 33 tokens per session scan A 2094bb5967e7
brainstorming is a skill published in the GitHub repository vudovn/ag-kit (8,170 stars, last pushed 5d ago), licensed MIT. It adds 33 tokens to every session and 1,262 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 2026-08-30.
