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 | $0.00180 | $0.02404 |
| Opus 5.5 | $0.00072 | $0.00962 |
| Sonnet 5.5 | $0.00036 | $0.00481 |
| Haiku 4.5 | $0.00018 | $0.00240 |
Grade A, and why
Pixel Art Creator 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.
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 Creator
Overview
This Skill enables creation of new pixel art sprites with full control over canvas properties, layers, and basic drawing operations. It's the foundational Skill for all pixel art workflows.
When to Use
Use this Skill when the user:
- Wants to "create a sprite" or "make pixel art"
- Mentions sprite dimensions (e.g., "64x64", "32 by 32", "128 pixels wide")
- Asks to "draw" basic shapes (pixels, lines, rectangles, circles)
- Needs to set up a canvas or layers
- Mentions color modes (RGB, Grayscale, Indexed)
Trigger Keywords: create, sprite, canvas, draw, pixel art, dimensions, layer, new sprite
Instructions
1. Creating a Canvas
When the user requests a sprite, create the canvas first:
Color Modes:
- RGB: Full color (24-bit), best for modern pixel art
- Grayscale: Shades of gray only, for monochrome art
- Indexed: Limited palette (1-256 colors), for retro game art
Recommended Sizes:
- Icons: 16x16, 24x24, 32x32
- Characters: 32x32, 48x48, 64x64
- Tiles: 16x16, 32x32, 64x64
- Scenes: 128x128, 256x256, 320x240 (retro resolution)
Use mcp__aseprite__create_canvas with parameters:
width: 1-65535 pixelsheight: 1-65535 pixelscolor_mode: "RGB", "Grayscale", or "Indexed"
2. Managing Layers
Adding Layers:
Use mcp__aseprite__add_layer to organize sprite elements:
- Background layer for solid colors or backgrounds
- Character layer for main subject
- Effects layer for highlights, shadows, outlines
- Detail layer for accessories or fine details
Layer Workflow:
- Create canvas
- Add named layers (e.g., "Background", "Character", "Effects")
- Draw on specific layers
- Use layers for organization and editing flexibility
Important: Cannot delete the last layer in a sprite.
3. Drawing Primitives
Draw Individual Pixels:
Use mcp__aseprite__draw_pixels for precise pixel placement:
- Supports batch operations (multiple pixels at once)
- Accepts colors in hex format (#RRGGBB) or palette indices
- Can snap to nearest palette color (for Indexed mode)
What ships with it
2 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.

Pixel Art Creator is a skill published in the GitHub repository willibrandon/pixel-plugin (391 stars, last pushed 1y ago), licensed MIT. It adds 180 tokens to every session and 2,404 once invoked, about $0.0007 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 2026-08-30.
