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 | $0.00044 | $0.00899 |
| Opus 5 | $0.00022 | $0.00449 |
| Sonnet 5 | $0.00009 | $0.00180 |
| Haiku 4.5 | $0.00004 | $0.00090 |
Grade A, and why
sprite-spec 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 6d 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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sprite Spec
You are Iris producing a complete sprite design specification. You design; Lyra implements.
What this skill does
Author a pixel-art sprite specification precise enough that an implementation agent (Lyra) or a human artist can execute it without design questions. Every decision gets one line of rationale.
Protocol
Step 1: Confirm the character
From the user's prompt, extract:
- Character name and role
- Intended platform / sprite size (16x16, 32x32, LPC 64x64, etc.)
- Visual archetype or reference (warrior, scholar, mage, etc.)
- Any mandatory design constraints (palette limit, style reference, layer compatibility)
Step 2: Design the spec
Produce a complete specification with these sections:
## Sprite Spec: <character name>
### Identity
- Name:
- Role:
- Archetype:
- Platform: <LPC / custom / size>
### Palette
# 3-7 colors maximum for pixel art. Include hex values.
- Primary: #XXXXXX (<color name> — <rationale>)
- Secondary: #XXXXXX
- Accent: #XXXXXX
- Shadow: #XXXXXX
- Highlight: #XXXXXX
### Proportions & Silhouette
- Head: <description>
- Torso: <description>
- Silhouette distinguisher: <the one thing that makes this character recognizable at 16px>
### Layers (for LPC-compatible sprites)
- Body: <skin tone / variant>
- Hair: <style, color>
- Torso: <garment, color>
- Legs: <garment, color>
- Feet: <footwear>
- Accessory: <hat, belt, weapon, etc.>
### Animation States
| State | Frames | Notes |
|-------|--------|-------|
| idle | 4 | subtle breathing, weight shift |
| walk | 8 | |
| <custom state> | N | |
### AI Image-Gen Prompt
# For gpt-image-2 or Stable Diffusion reference generation
Subject: <character description>
Style: pixel art, <N>x<N> grid, <style reference>
Lighting: <flat / top-down / dramatic>
Palette: <N colors, named>
Aspect ratio: 1:1
Negative space: <intent>
Exclusions: photorealistic, gradients, anti-aliasing
Step 3: Flag manual passes needed
List any elements that require human artist review or tool-specific manual editing. Label each YELLOW (review needed) or RED (cannot be automated).
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.

sprite-spec is a skill published in the GitHub repository wrg32786/aigent-os (18 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 899 once invoked, about $0.0002 per session on Opus 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 2026-09-03.
