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 | $0.00061 | $0.02236 |
| Opus 5 | $0.00030 | $0.01118 |
| Sonnet 5 | $0.00012 | $0.00447 |
| Haiku 4.5 | $0.00006 | $0.00224 |
Grade A, and why
game-art-2d 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 255 lines — stays where its author put it; the contents beside it link to each section on GitHub.
2D Game Art Studio
Create cohesive 2D game art as runtime assets, not isolated illustrations. Combine Codex image generation with deterministic local processing and in-engine validation.
Operating boundaries
- Work only in 2D. Treat isometric art as 2D when the runtime consumes sprites or tiles; route meshes, rigs, materials, and 3D scenes elsewhere.
- Prefer the project's established art direction over this skill's defaults.
- Default to pixel art only when the project and user provide no style.
- Distinguish concept art from shippable art. Never present a concept sheet, poster composition, or arbitrary AI grid as a runtime-ready asset.
- Distinguish map art from level design. Keep collision, traversal, spawn, trigger, encounter, and navigation data explicit in the game or level format.
- Create original work. Do not copy protected characters, maps, interfaces, or distinctive living-artist styles. Translate references into general visual traits.
- Preserve existing assets. Use versioned sibling filenames unless the user explicitly requests replacement.
Choose the work mode
Use one or more modes, but keep the current deliverable explicit:
- Direction: define a visual language, style guide, palette, shape grammar, camera, scale, and asset constraints.
- Production: generate or edit canonical assets, variants, animation frames, tiles, backgrounds, or interface art.
- Integration: normalize, pack, import, configure, and validate assets in the target runtime.
- Audit: inspect an existing asset set for coherence, technical defects, missing states, readability, or runtime risk.
Core workflow
1. Inspect the project
Read the nearest agent instructions, art docs, engine configuration, asset
manifests, source art, runtime consumers, and naming conventions. Inspect
representative images with view_image. Record:
- engine and renderer;
- camera and projection;
- target viewport and display scale;
- existing art style and palette;
- expected source and shipping formats;
- sprite cell, tile, atlas, pivot, and animation conventions;
- performance, accessibility, and content constraints.

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.
- 11d ago First seen · 255 lines · 61 tokens per session scan A 63f405c6521f
game-art-2d is a skill published in the GitHub repository woliveiras/geremmyas (10 stars, last pushed 1mo ago), licensed MIT. It adds 61 tokens to every session and 2,236 once invoked, about $0.0003 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 2026-08-31.
