pixel-art

pixel-art is a skill for Claude Code, Codex from mateaix/mateclaw. It costs 20 tokens per session (2,019 once invoked), scanned A, a copy of pixel-art, Apache-2.0.

A toolkit that converts images into retro pixel art using visual styles and color palettes associated with systems such as the NES, Game Boy, and PICO-8.

In plain words
What is it for?
Making pixel-art images, sprites, characters, avatars, posters, album covers, and social posts, plus short animated MP4 or GIF loops with effects such as rain, snow, or fireflies.
Why use it?
It removes the need to manually reduce images, choose era-specific colors, and create simple looping effects.

Token cost

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.

Security

Grade A, and why

pixel-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 4d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/__init__.py, scripts/palettes.py, scripts/pixel_art_video.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Origin

This is a copy

95% identical to pixel-art — 30 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.

How it starts

The opening of the file, as written. The whole thing — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pixel Art

Convert any image into retro pixel art, then optionally animate it into a short MP4 or GIF with era-appropriate effects (rain, fireflies, snow, embers).

Two scripts ship with this skill:

  • scripts/pixel_art.py — photo → pixel-art PNG (Floyd-Steinberg dithering)
  • scripts/pixel_art_video.py — pixel-art PNG → animated MP4 (+ optional GIF)

Each is importable or runnable directly. Presets snap to hardware palettes when you want era-accurate colors (NES, Game Boy, PICO-8, etc.), or use adaptive N-color quantization for arcade/SNES-style looks.

When to Use

  • User wants retro pixel art from a source image
  • User asks for NES / Game Boy / PICO-8 / C64 / arcade / SNES styling
  • User wants a short looping animation (rain scene, night sky, snow, etc.)
  • Posters, album covers, social posts, sprites, characters, avatars

Workflow

Before generating, confirm the style with the user. Different presets produce very different outputs and regenerating is costly.

Step 1 — Offer a style

Call clarify with 4 representative presets. Pick the set based on what the user asked for — don't just dump all 14.

Default menu when the user's intent is unclear:

clarify(
    question="Which pixel-art style do you want?",
    choices=[
        "arcade — bold, chunky 80s cabinet feel (16 colors, 8px)",
        "nes — Nintendo 8-bit hardware palette (54 colors, 8px)",
        "gameboy — 4-shade green Game Boy DMG",
        "snes — cleaner 16-bit look (32 colors, 4px)",
    ],
)

When the user already named an era (e.g. "80s arcade", "Gameboy"), skip clarify and use the matching preset directly.

Step 2 — Offer animation (optional)

If the user asked for a video/GIF, or the output might benefit from motion, ask which scene:

clarify(
    question="Want to animate it? Pick a scene or skip.",
    choices=[
        "night — stars + fireflies + leaves",
        "urban — rain + neon pulse",
        "snow — falling snowflakes",
        "skip — just the image",
    ],
)

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.
