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 | $0.00017 | $0.01286 |
| Opus 5 | $0.00009 | $0.00643 |
| Sonnet 5 | $0.00003 | $0.00257 |
| Haiku 4.5 | $0.00002 | $0.00129 |
Grade A, and why
game-art 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 8d 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.

Game Art Principles
Visual design thinking for games - style selection, asset pipelines, and art direction.
1. Art Style Selection
Decision Tree
What feeling should the game evoke?
│
├── Nostalgic / Retro
│ ├── Limited palette? → Pixel Art
│ └── Hand-drawn feel? → Vector / Flash style
│
├── Realistic / Immersive
│ ├── High budget? → PBR 3D
│ └── Stylized realism? → Hand-painted textures
│
├── Approachable / Casual
│ ├── Clean shapes? → Flat / Minimalist
│ └── Soft feel? → Gradient / Soft shadows
│
└── Unique / Experimental
└── Define custom style guide
Style Comparison Matrix
| Style | Production Speed | Skill Floor | Scalability | Best For |
|---|---|---|---|---|
| Pixel Art | Medium | Medium | Hard to hire | Indie, retro |
| Vector/Flat | Fast | Low | Easy | Mobile, casual |
| Hand-painted | Slow | High | Medium | Fantasy, stylized |
| PBR 3D | Slow | High | AAA pipeline | Realistic games |
| Low-poly | Fast | Medium | Easy | Indie 3D |
| Cel-shaded | Medium | Medium | Medium | Anime, cartoon |
2. Asset Pipeline Decisions
2D Pipeline
| Phase | Tool Options | Output |
|---|---|---|
| Concept | Paper, Procreate, Photoshop | Reference sheet |
| Creation | Aseprite, Photoshop, Krita | Individual sprites |
| Atlas | TexturePacker, Aseprite | Spritesheet |
| Animation | Spine, DragonBones, Frame-by-frame | Animation data |
| Integration | Engine import | Game-ready assets |
3D Pipeline
| Phase | Tool Options | Output |
|---|---|---|
| Concept | 2D art, Blockout | Reference |
| Modeling | Blender, Maya, 3ds Max | High-poly mesh |
| Retopology | Blender, ZBrush | Game-ready mesh |
| UV/Texturing | Substance Painter, Blender | Texture maps |
| Rigging | Blender, Maya | Skeletal rig |
| Animation | Blender, Maya, Mixamo | Animation clips |
| Export | FBX, glTF | Engine-ready |
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.
- 8d ago First seen · 186 lines · 17 tokens per session scan A ab7029cb91c4
game-art is a skill published in the GitHub repository vudovn/ag-kit (8,169 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 1,286 once invoked, about $0.0001 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.
