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 | $0.00012 | $0.01332 |
| Opus 5 | $0.00006 | $0.00666 |
| Sonnet 5 | $0.00002 | $0.00266 |
| Haiku 4.5 | $0.00001 | $0.00133 |
Grade A, and why
pixel-new 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 yesterday.
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-new - Quick Sprite Creation
Creates a new pixel art sprite with optional presets for size and palette.
Usage
/pixel-new [size] [palette]
Arguments
size (optional): Canvas dimensions or preset name
- Presets: icon, small, medium, large, tile, gameboy, nes
- Custom: WIDTHxHEIGHT (e.g., 64x64, 128x96)
- Default: 64x64
palette (optional): Color palette preset
- retro, nes, gameboy, c64, cga, snes, custom
- Default: RGB (no palette limit)
Examples
/pixel-new
→ Creates 64x64 RGB canvas
/pixel-new icon
→ Creates 32x32 RGB canvas
/pixel-new gameboy gameboy
→ Creates 160x144 canvas with Game Boy 4-color palette
/pixel-new 128x128 nes
→ Creates 128x128 canvas with NES palette
/pixel-new tile retro
→ Creates 16x16 canvas with retro 16-color palette
Size Presets
- icon: 32x32 (for icons, small sprites)
- small: 48x48 (characters, items)
- medium: 64x64 (default, versatile)
- large: 128x128 (detailed sprites, portraits)
- tile: 16x16 (tilemap tiles)
- gameboy: 160x144 (Game Boy screen resolution)
- nes: 256x240 (NES screen resolution)
Palette Presets
- retro: 16-color palette (generic retro aesthetic)
- nes: 54-color NES palette

- cga: 4-color CGA palette
- snes: 256-color SNES-style palette
- custom: Prompts for custom palette colors
Implementation
Parse arguments from $ARGUMENTS:
- Extract size argument (first arg)
- Extract palette argument (second arg)
- Map size preset to dimensions or parse WxH
- Create canvas with mcp__aseprite__create_canvas
- If palette specified, set palette with mcp__aseprite__set_palette
- Confirm creation with sprite info
Size Preset Mapping
icon → 32x32
small → 48x48
medium → 64x64
large → 128x128
tile → 16x16
gameboy → 160x144
nes → 256x240
Palette Details
retro (16 colors):
- Generic retro palette with balanced colors
- Good for general pixel art without console constraints
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.
