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.

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 | $0.00026 | $0.01872 |
| Opus 5.5 | $0.00010 | $0.00749 |
| Sonnet 5.5 | $0.00005 | $0.00374 |
| Haiku 4.5 | $0.00003 | $0.00187 |
Grade A, and why
tailwind-patterns 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 1mo 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.

Tailwind CSS Patterns (v4)
Modern utility-first CSS with CSS-native configuration.
1. Tailwind v4 Architecture
What Changed from v3
| v3 (Legacy) | v4 (Current) |
|---|---|
tailwind.config.js |
CSS-based @theme directive |
| PostCSS plugin | Oxide engine (full builds ~5x, incremental >100x) |
| JIT mode | Native, always-on |
| Plugin system | CSS-native features |
@apply directive |
Still works, discouraged |
v4 Core Concepts
| Concept | Description |
|---|---|
| CSS-first | Configuration in CSS, not JavaScript |
| Oxide Engine | Rust-based compiler, much faster |
| Native Nesting | CSS nesting without PostCSS |
| CSS Variables | All tokens exposed as --* vars |
2. CSS-Based Configuration
Theme Definition
@theme {
/* Colors - use semantic names */
--color-primary: oklch(0.7 0.15 250);
--color-surface: oklch(0.98 0 0);
--color-surface-dark: oklch(0.15 0 0);
/* Spacing scale */
--spacing-xs: 0.25rem;
--spacing-sm: 0.5rem;
--spacing-md: 1rem;
--spacing-lg: 2rem;
/* Typography */
--font-sans: 'Inter', system-ui, sans-serif;
--font-mono: 'JetBrains Mono', monospace;
}
When to Extend vs Override
| Action | Use When |
|---|---|
| Extend | Adding new values alongside defaults |
| Override | Replacing default scale entirely |
| Semantic tokens | Project-specific naming (primary, surface) |
3. Container Queries (v4 Native)
Breakpoint vs Container
| Type | Responds To |
|---|---|
Breakpoint (md:) |
Viewport width |
Container (@container) |
Parent element width |
Container Query Usage
| Pattern | Classes |
|---|---|
| Define container | @container on parent |
| Container breakpoint | @sm:, @md:, @lg: on children |
| Named containers | @container/card for specificity |
When to Use
| Scenario | Use |
|---|---|
| Page-level layouts | Viewport breakpoints |
| Component-level responsive | Container queries |
| Reusable components | Container queries (context-independent) |
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.

tailwind-patterns is a skill published in the GitHub repository vudovn/ag-kit (8,199 stars, last pushed 3d ago), licensed MIT. It adds 26 tokens to every session and 1,872 once invoked, about $0.0001 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 2026-08-30.
