Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00125 | $0.02475 |
| Opus 5 | $0.00063 | $0.01238 |
| Sonnet 5 | $0.00025 | $0.00495 |
| Haiku 4.5 | $0.00013 | $0.00248 |
Grade A, and why
genart-ops 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 10d 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 — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generative Art Operations
Practical patterns for creative coding and generative art. Covers three.js, p5.js, SVG generation, GLSL shaders, procedural algorithms, and color theory for computational aesthetics.
Color-ops handles CSS color, accessibility, and design tokens. This skill focuses on generative/procedural color techniques (palette algorithms, shader color, gradient interpolation in perceptual space).
Application/game-scale three.js — GLTF asset pipelines, AnimationMixer, fixed-timestep game loops, physics (rapier/cannon-es), react-three-fiber, instancing/disposal at scale — is threejs-ops. This skill owns the creative/shader side of three.js.
The detailed code, technique walkthroughs, and parameter tables live in the references below. This body holds the decisions: which surface, which algorithm, which color space, in what order.
Workflow & tool selection
Pick the rendering surface first — it determines everything downstream:
| Goal | Surface | Reference |
|---|---|---|
| 2D sketches, fast iteration, teaching | p5.js (Canvas2D or WebGL) | p5-sketches |
| 3D scenes, camera, lighting, post-processing | three.js | threejs-scenes |
| Per-pixel fields, full-screen shaders, ray marching | raw GLSL / WebGL fragment | glsl-shaders |
| Resolution-independent vectors, plotter/print | SVG | svg-generation |
Then generate content (CPU) and colorize it (perceptual space):
| Need | Algorithm family | Reference |
|---|---|---|
| Organic texture, terrain, marble | noise (value/simplex/FBM/domain-warp) | procedural-algorithms |
| Even point distribution | Poisson disk | procedural-algorithms |
| Trees, fractals, self-similar curves | L-systems | procedural-algorithms |
| Emergent motion/patterns | flow fields / cellular automata | procedural-algorithms |
| Space partitioning | Voronoi / Delaunay (d3-delaunay) | procedural-algorithms |
| Tile worlds with adjacency rules | wave function collapse | procedural-algorithms |
| Palettes, gradients, harmonies | OKLAB / OKLCH | color-and-palettes |
What ships with it
6 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.

genart-ops is a skill published in the GitHub repository 0xDarkMatter/claude-mods (35 stars, last pushed 18d ago), licensed MIT. It adds 125 tokens to every session and 2,475 once invoked, about $0.0006 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 2026-08-30.
