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 | $0.00097 | $0.02229 |
| Opus 5 | $0.00048 | $0.01115 |
| Sonnet 5 | $0.00019 | $0.00446 |
| Haiku 4.5 | $0.00010 | $0.00223 |
Grade A, and why
rocaille-shader 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.

Rocaille Shader Skill
Generate organic, swirling light effects through progressive domain warping - a technique that creates increasingly complex patterns by iteratively displacing coordinates using sinusoidal functions.
Core Technique
The Rocaille effect builds complexity through repeated application of:
v += sin(v.yx + t) / amplitude;
Where:
vis a 2D coordinate vectorv.yxswaps x/y components creating characteristic swirltis time for animationamplitudecontrols warp intensity (1.0 = strong, 4.0 = subtle)- Each iteration adds more organic complexity
Quick Reference
| Warps | Effect | Use Case |
|---|---|---|
| 1-2 | Subtle wave | Backgrounds, subtle motion |
| 3-5 | Organic flow | Music visualizers, hero sections |
| 6-9 | Complex swirl | Psychedelic effects, main attraction |
| 10+ | Chaotic | Experimental, glitch art |
Usage
To generate a shader, specify:
- Warp count (1-15): Number of displacement iterations
- Color mode:
basic,rainbow,monochrome,neon, or custom RGB - Output format:
shadertoy,threejs,webgl,p5js
Generate Custom Shader
Run the generator script:
python3 scripts/rocaille_generator.py --warps 5 --color rainbow --format shadertoy
Options:
--warps N- Number of warp iterations (default: 5)--color MODE- Color mode: basic, rainbow, monochrome, neon (default: rainbow)--format FMT- Output format: shadertoy, threejs, webgl, p5js, all (default: shadertoy)--amplitude N- Warp intensity divisor (default: 2.0)--speed N- Animation speed multiplier (default: 1.0)--demo- Generate interactive HTML demo page

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.

rocaille-shader is a skill published in the GitHub repository tdimino/claude-code-minoan (41 stars, last pushed yesterday), licensed MIT. It adds 97 tokens to every session and 2,229 once invoked, about $0.0005 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.
