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 1mo 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.

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",
    ],
)

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.
