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 | $0.01376 |
| Opus 5 | $0.00009 | $0.00688 |
| Sonnet 5 | $0.00003 | $0.00275 |
| Haiku 4.5 | $0.00002 | $0.00138 |
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.
This is a copy
86% identical to game-art — 14 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.

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.

game-art is a skill published in the GitHub repository frogobox/frogo-sdk (21 stars, last pushed 6d ago), licensed Apache-2.0. It adds 17 tokens to every session and 1,376 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to game-art, differing in 14 lines, and is treated as a copy.

screenshot-game-view
Capture a screenshot of the Unity Editor's Game View by reading its internal render texture directly. Image size matches the current Game View resolution; the tool corrects Y-flip on DirectX / Metal so the output is always upright. Requires an open Game View window.
threejs-audio-generator
Generate, convert, clean, and integrate audio for Three.js browser games with ElevenLabs: sound effects, looping ambience, UI sounds, impact/weapon/vehicle audio, creature and boss stingers, announcer and dialogue TTS, voice conversion from a scratch performance, voice cleanup, audio manifests, and Web Audio…
threejs-world-generation
Build deterministic, editable, free-viewpoint Three.js worlds from text or structured briefs. Use for cinematic 3D terrain, semantic regions, procedural biomes, explicit landmarks, environmental scattering, camera fly-throughs, world diagnostics, or requests for a real 3D environment rather than generated 2D footage.…
sound-effects
Generate sound effects from text descriptions using ElevenLabs. Use when creating sound effects, generating audio textures, producing ambient sounds, cinematic impacts, UI sounds, or any audio that isn't speech. Supports looping, duration control, and prompt influence tuning.
sprite-gen
Generate clean 2D game sprites and animation atlases with a component-row pipeline: base identity, numeric sprite-request SSoT, per-state layout guides, image-gen row strips, chroma-key alpha cleanup, connected-component frame extraction, cell-based atlas composition, QA reports, and runtime manifest framelayout. Its…
audio-design
Implement game audio practice — bus/mixer architecture and gain in decibels, ducking (sidechain), adaptive/dynamic music via layering and re-sequencing, SFX variation, and beat synchronization. Engine-neutral. Use when the user mentions audio mixing, audio buses, adaptive/dynamic music, ducking, SFX variation, music…
