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 | $0.00037 | $0.10524 |
| Opus 5.5 | $0.00015 | $0.04210 |
| Sonnet 5.5 | $0.00007 | $0.02105 |
| Haiku 4.5 | $0.00004 | $0.01052 |
Grade A, and why
pixelart 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 2mo 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 — 829 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generate a pixel art HTML file based on the user's request: $ARGUMENTS
Input Modes
Mode 1 — Single asset (default):
Parse input to extract size (e.g. 16x16, 32x32, 192x128) and prompt. If size is omitted, default to 16x16.
/pixelart 32x32, a wizard with a glowing staff
/pixelart 80x85, stone cottage with red tile roof
/pixelart 50x40, a fox sitting in grass
Mode 2 — Tileset: When prompt contains "tileset", "sprite sheet", or "asset pack", generate a complete sheet of related assets on a single canvas.
/pixelart tileset, medieval village
/pixelart tileset, dungeon crawler
/pixelart tileset, forest nature pack
/pixelart tileset, farm animals
Output
A single, complete, self-contained .html file. No external images or dependencies.
Auto-Decision Rules
Size → Detail Level
| Size | Detail | Max Colors | Shading |
|---|---|---|---|
| 8×8 | minimal | 3–5 | Flat colors, no shading |
| 12×12 | standard | 5–8 | 1 shadow tone per material |
| 16×16 | standard | 8–12 | 1 shadow tone per material |
| 16×24, 24×24 | detailed | 10–16 | Highlight + base + shadow per material |
| 32×32+ | detailed | 12–20 | Highlight + base + shadow, texture hints |
| 48×48+ | ultra | 15–25 | Multi-layer shading, dithering |
| 96×64+ (canvas) | ultra | Unlimited | Procedural FBM noise, Bayer dithering |
| 48×96+ (asset) | ultra | Unlimited | Procedural texture engine, region-based |
Prompt → Rendering Method
| Prompt implies... | Method |
|---|---|
| Simple icon / item / emoji | CSS box-shadow (zero JS, static) |
| Character / sprite | CSS Grid + JS (per-pixel control) |
| "animated", movement, effects | Grid + animation JS |
| Landscape, scene, environment | Canvas (procedural generation) |
| Building, tileset, game asset | Canvas (procedural texture engine) |
| Animal, creature, organic | Canvas (procedural organic textures) |
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.

pixelart is a skill published in the GitHub repository SbName/yoyopixel (7 stars, last pushed 6mo ago), licensed MIT. It adds 37 tokens to every session and 10,524 once invoked, about $0.0001 per session on Opus 5.5. 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.
