Description

Generate algorithmic visual art — flow fields, fractals, cellular automata, circle packing, wave patterns. SVG + PNG output.

README (SKILL.md)

GenArt Skill

Procedural visual art generator using Python. Produces SVG vector art and PNG raster output from algorithmic patterns and mathematical structures.

Algorithms

Flow Fields

Perlin noise-based vector fields that guide particle motion, creating organic flowing patterns and fluid-like aesthetics.

Fractals

Recursive geometric structures: Mandelbrot sets, Julia sets, L-systems, and self-similar branching patterns with configurable depth and parameters.

Cellular Automata

Conway's Game of Life and variants, generating complex patterns from simple local rules. Produces static snapshots or animated sequences.

Circle Packing

Algorithm-driven placement of circles in constrained spaces, creating organic compositions with visual balance.

Wave Patterns

Sinusoidal and superposed wave interference, creating ripple effects, moiré patterns, and harmonic visualizations.

Usage

genart.py --algorithm flow_field --output art.svg [--params "noise=0.5,scale=10"]
genart.py --algorithm fractal --output mandelbrot.png --width 1024 --height 1024
genart.py --algorithm cellular_automata --output ca.svg --iterations 100
genart.py --algorithm circle_pack --output circles.svg --target-count 200
genart.py --algorithm waves --output waves.png --frequency 5 --amplitude 100

Outputs SVG for scalable vector art or PNG for raster. All fully deterministic and scriptable.

Features

Deterministic: Seed-based generation for reproducible art
Scalable: SVG output scales infinitely without quality loss
Raster export: PNG rendering for web and print
Configurable: Every algorithm exposes tunable parameters
Fast: Optimized Python with optional NumPy acceleration

Usage Guidance

The tool looks like a genuine generative-art script, but there are a few gaps you should check before installing or running it: 1) Inspect the full genart.py for any subprocess calls — search for subprocess.run/ Popen or explicit command strings; if it calls external programs to render PNGs, confirm which binaries (inkscape, rsvg-convert, ImageMagick) and that you are comfortable providing those. 2) Confirm there are no network calls or attempts to read unexpected files (home dir, SSH keys, shell history). 3) Note the SKILL.md mentions optional NumPy but the metadata lists no dependencies; if you need NumPy, install it separately from a trusted source. 4) Because source/homepage are unspecified, consider running the script in a sandboxed environment (container or VM) first, or review the entire source for unexpected behavior. If you want, I can scan the rest of genart.py (the truncated portion) for subprocess usage, file I/O, or network activity — provide the remainder and I'll review it line-by-line.

Capability Analysis

Type: OpenClaw Skill Name: genart Version: 2.0.0 The genart skill is a legitimate generative art engine that produces SVG and PNG outputs using various mathematical algorithms (fractals, flow fields, etc.). The code in genart.py uses standard Python libraries and includes a subprocess call to /usr/bin/rsvg-convert for PNG conversion, which is consistent with its stated purpose and lacks any indicators of malicious intent or data exfiltration.

Capability Assessment

ℹ Purpose & Capability

Name, description, SKILL.md, and the visible portions of genart.py align: this is a Python generative-art tool producing SVG/PNG. However, the package advertises 'PNG rendering' and 'optional NumPy acceleration' while registry metadata lists no required binaries or environment and no install spec. Also package.json is present for a Node package even though the runtime is Python; these mismatches are unexpected though not necessarily malicious.

ℹ Instruction Scope

SKILL.md instructs running genart.py with CLI flags and claims deterministic, scriptable outputs. The instructions do not mention any external tools required to produce PNG output or optional acceleration. The code imports subprocess and os (visible), which suggests it may invoke external rasterizers (e.g., inkscape, rsvg-convert, ImageMagick) or perform filesystem operations — none of which are declared in SKILL.md or registry metadata. This omission is a scope/information gap that should be clarified.

✓ Install Mechanism

There is no install specification (instruction-only skill with a bundled Python script). That is the lowest-risk install model. The presence of package.json is somewhat odd for a Python-only tool but not itself dangerous. No remote download URLs or extract operations are present in the metadata.

✓ Credentials

The skill requests no environment variables, credentials, or config paths, which is proportionate for a local art generator. There are no declared secrets. That said, the code's use of subprocess/os means it could read or write filesystem content if implemented to do so; the current metadata does not claim such access explicitly.

✓ Persistence & Privilege

The skill is not always-enabled and uses default invocation settings. It does not request elevated or persistent platform privileges in the metadata. Nothing in the manifest indicates it would modify other skills or global agent configuration.

How to Use

Make sure OpenClaw is installed (local or Docker)
Run the install command in chat: /install genart
After installation, invoke the skill by name or use /genart
Provide required inputs per the skill's parameter spec and get structured output
