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 | $0.00349 | $0.04673 |
| Opus 5 | $0.00175 | $0.02337 |
| Sonnet 5 | $0.00070 | $0.00935 |
| Haiku 4.5 | $0.00035 | $0.00467 |
Grade A, and why
pixel-art-studio 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 9d 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.

Pixel Art Studio
Programmatic pixel art creation with palette discipline, dithering, animation, and automated quality control. Designed for production-quality output, not "look-pixelated filter on a photo."
When to use this skill
| User says | What to do |
|---|---|
| "make a pixel art X" / "create a sprite" | Static sprite workflow |
| "animate this", "walk cycle", "idle animation" | Animation workflow |
| "convert this image to pixel art", "pixelate this" | Preprocessing workflow |
| "generate sprite sheet" | Sprite sheet workflow |
| "review this pixel art / score it" | Quality review workflow |
| "show palette options" / "use Endesga 64" | Palette browsing |
If user provides only a vague description ("a cat sprite"), pick the standard sprite workflow with 32×32 + Endesga 32 palette as the safe default, then offer to iterate.
Prerequisites
pip install Pillow numpy
# Optional but recommended for advanced quality checks:
pip install scikit-image scipy
Pillow is mandatory; numpy is mandatory; the rest are optional (the scripts will degrade gracefully).
Core principle: design discipline > pixel quantity
A 16×16 sprite with deliberate cluster choices reads better than a 64×64 with random pixel noise. Always start from the smallest grid that conveys the subject, expand only when needed for detail.
The four pillars of quality (encoded in scripts/quality_check.py):
- Per-pixel hygiene — no orphan single pixels, no parallel doublies, no banded ramps
- Cluster coherence — pixel groups read as recognizable shapes, not noise
- Palette discipline — limited (≤32 typically), with hue rotation across luminance ramp
- Silhouette readability — render-as-solid-shape and verify subject is recognizable
When in doubt, run quality_check.py after generation and fix issues until score ≥ 80/100.
What ships with it
60 files 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.
- 9d ago First seen · 398 lines · 349 tokens per session scan A f0135af13140
pixel-art-studio is a skill published in the GitHub repository AnastasiyaW/codex-claude-code-config (149 stars, last pushed today), licensed MIT. It adds 349 tokens to every session and 4,673 once invoked, about $0.0017 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.
