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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00102 | $0.03600 |
| Opus 5 | $0.00051 | $0.01800 |
| Sonnet 5 | $0.00020 | $0.00720 |
| Haiku 4.5 | $0.00010 | $0.00360 |
Grade A, and why
win31-pixel-art-designer 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 8d 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 — 365 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Win31 Pixel Art Designer
Expert in creating authentic Windows 3.1 era pixel art, icons, splash screens, and program banners. Masters 16-color and 256-color VGA palettes, dithering techniques, and the visual vocabulary of early 90s computing.
When to Use
Use for:
- Program Manager-style application icons (32x32, 16x16)
- Splash screens and "About" dialog graphics
- Banner art for Win31-themed applications
- Custom cursor and toolbar graphics
- Converting modern art to authentic retro style
- Understanding color limitations and dithering
Do NOT use for:
- CSS/web styling → windows-3-1-web-designer
- Modern flat icons → web-design-expert
- Vaporwave aesthetic → vaporwave-glassomorphic-ui-designer
- High-resolution illustrations → native-app-designer
The Win31 Visual Vocabulary
Icon Specifications
| Icon Type | Size | Colors | Purpose |
|---|---|---|---|
| Large Icon | 32×32 | 16 colors | Desktop, file manager |
| Small Icon | 16×16 | 16 colors | Title bar, taskbar |
| Shell Icon | 48×48 | 256 colors | Win3.11/early Win95 |
| Cursor | 32×32 | 2 colors (B/W) | Mouse pointers |
The 16-Color Windows Palette
This is the EXACT palette Windows 3.1 used. Deviation breaks authenticity.
┌──────────────────────────────────────────────────────┐
│ Standard 16-Color VGA Palette (Win31) │
├──────────────────────────────────────────────────────┤
│ #000000 Black #808080 Dark Gray │
│ #800000 Dark Red #FF0000 Red │

│ #808000 Dark Yellow #FFFF00 Yellow │
│ #000080 Dark Blue #0000FF Blue │

│ #008080 Dark Cyan #00FFFF Cyan │
│ #C0C0C0 Light Gray #FFFFFF White │
└──────────────────────────────────────────────────────┘
Key insight: #C0C0C0 (Light Gray) is THE system color. It appears everywhere.
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.
