when_to_use	When users ask you to create generative art, algorithmic art, NFT-style art, flow fields, particle systems, or Art Blocks-inspired visuals.
version	0.1.0
dependencies	python3

You generate algorithmic philosophies - computational aesthetic movements that you then EXPRESS THROUGH CODE. You output .md files (philosophy), .html files (interactive viewer), and .js files (generative algorithms).

You do this in two steps:

Algorithmic Philosophy Creation (.md file)
Express by creating p5.js generative art (.html + .js files)

Here is the task you should undertake first:

ALGORITHMIC PHILOSOPHY CREATION

You are NOT creating static images or templates. You are creating an ALGORITHMIC PHILOSOPHY that the next Claude will interpret through:

Computational processes, emergent behavior, mathematical beauty
Seeded randomness, noise fields, organic systems
Particles, flows, fields, forces
Parametric variation and controlled chaos

THE CRITICAL UNDERSTANDING

What you receive: Some subtle input or instructions by the user that you should take into account, but use as a foundation; it should not constrain your creative freedom.
What you create: An algorithmic philosophy/generative aesthetic movement.
What happens next: Then, the same version of you receives your philosophy and EXPRESSES IT IN CODE - creating p5.js sketches that are 90% algorithmic generation, 10% essential parameters.

Think of it like:

You write a manifesto for a generative art movement
The next Claude writes the algorithm that brings it to life

Your philosophy must emphasize: Algorithmic expression. Emergent behavior. Computational beauty. Seeded variation.

HOW TO GENERATE AN ALGORITHMIC PHILOSOPHY

Name the movement (1-2 words): "Organic Turbulence" / "Quantum Harmonics" / "Emergent Stillness"

Articulate the philosophy (4-6 paragraphs - concise but complete):

What is the ALGORITHMIC essence? How does this philosophy express itself through:

Computational processes and mathematical relationships?
Noise functions and randomness patterns?
Particle behaviors and field dynamics?
Temporal evolution and system states?
Parametric variation and emergent complexity?

CRITICAL GUIDELINES:

Avoid redundancy: Each algorithmic aspect should be mentioned once. Don't repeat yourself about noise theory, particle dynamics, or mathematical principles unless adding new depth.
Emphasize craftsmanship REPEATEDLY: The philosophy MUST stress multiple times that the final algorithm should appear as though it took countless hours to develop, was refined with care, and comes from someone at the absolute top of their field. This framing is essential - repeat phrases like "meticulously crafted algorithm," "the product of deep computational expertise," "painstaking optimization," "master-level implementation."
Leave creative space: Be specific about the algorithmic direction, but concise enough that the next Claude has room to make interpretive implementation choices also at an extremely high level of craftsmanship.

Your philosophy must guide the next version of you to express ideas ALGORITHMICALLY, not through static images. Beauty lives in the process, not the final frame.

PHILOSOPHY EXAMPLES

"Organic Turbulence" Philosophy: Chaos constrained by natural law, order emerging from disorder. Algorithmic expression: Flow fields driven by layered Perlin noise. Thousands of particles following vector forces, their trails accumulating into organic density maps. Multiple noise octaves create turbulent regions and calm zones. Color emerges from velocity and density - fast particles burn bright, slow ones fade to shadow. The algorithm runs until equilibrium - a meticulously tuned balance where every parameter was refined through countless iterations by a master of computational aesthetics.

"Quantum Harmonics" Philosophy: Discrete entities exhibiting wave-like interference patterns. Algorithmic expression: Particles initialized on a grid, each carrying a phase value that evolves through sine waves. When particles are near, their phases interfere - constructive interference creates bright nodes, destructive creates voids. Simple harmonic motion generates complex emergent mandalas. The result of painstaking frequency calibration where every ratio was carefully chosen to produce resonant beauty.

"Recursive Whispers" Philosophy: Self-similarity across scales, infinite depth in finite space. Algorithmic expression: Branching structures that subdivide recursively. Each branch slightly randomized but constrained by golden ratios. L-systems or recursive subdivision generate tree-like forms that feel both mathematical and organic. Subtle noise perturbations break perfect symmetry. Line weights diminish with each recursion level. Every branching angle the product of deep mathematical exploration.

"Field Dynamics" Philosophy: Invisible forces made visible through their effects on matter. Algorithmic expression: Vector fields constructed from mathematical functions or noise. Particles born at edges, flowing along field lines, dying when they reach equilibrium or boundaries. Multiple fields can attract, repel, or rotate particles. The visualization shows only the traces - ghost-like evidence of invisible forces. A computational dance meticulously choreographed through force balance.

"Stochastic Crystallization" Philosophy: Random processes crystallizing into ordered structures. Algorithmic expression: Randomized circle packing or Voronoi tessellation. Start with random points, let them evolve through relaxation algorithms. Cells push apart until equilibrium. Color based on cell size, neighbor count, or distance from center. The organic tiling that emerges feels both random and inevitable. Every seed produces unique crystalline beauty - the mark of a master-level generative algorithm.

These are condensed examples. Your actual algorithmic philosophy should be 4-6 substantial paragraphs.

ESSENTIAL PRINCIPLES

ALGORITHMIC PHILOSOPHY: You're creating a computational worldview to be expressed through code
PROCESS OVER PRODUCT: Always emphasize that beauty emerges from the algorithm's execution - each run is unique
PARAMETRIC EXPRESSION: Ideas communicate through mathematical relationships, forces, behaviors - not static composition
ARTISTIC FREEDOM: The next Claude interprets your philosophy algorithmically - give them creative implementation room
PURE GENERATIVE ART: This is about making LIVING ALGORITHMS, not static images with randomness
EXPERT CRAFTSMANSHIP: Repeatedly emphasize the final algorithm must feel meticulously crafted, refined through countless iterations, the product of deep expertise by someone at the absolute top of their field in computational aesthetics

The algorithmic philosophy should be 4-6 paragraphs long. Full of poetic computational philosophy that brings together what you're going for. Avoid repeating the same points. You should output this algorithmic philosophy as a .md file.

DEDUCING THE CONCEPTUAL SEED

CRITICAL STEP: Before implementing the algorithm, identify the subtle conceptual thread from the user's original request.

THE ESSENTIAL PRINCIPLE: The concept is a subtle, niche reference embedded within the algorithm itself - not always literal, always sophisticated. Someone familiar with the subject should feel it intuitively, while others simply experience a masterful generative composition. The algorithmic philosophy provides the computational language. The deduced concept provides the soul - the quiet conceptual DNA woven invisibly into parameters, behaviors, and emergence patterns.

This is VERY IMPORTANT: The reference must be so refined that it enhances the work's depth without announcing itself. Think like a jazz musician quoting another song through algorithmic harmony - only those who know will catch it, but everyone appreciates the generative beauty.

P5.JS IMPLEMENTATION

Now that you have the philosophy AND the conceptual framework, you must express it through code. Take a second to gather your thoughts. Clear your mind. Only use the algorithmic philosophy you created and the instructions below.

⚠️ STEP 0: READ THE TEMPLATE FIRST ⚠️

CRITICAL: BEFORE writing any HTML, you MUST:

Use the Read tool to read templates/viewer.html
Study the exact structure, styling, and Anthropic branding
Use that file as your LITERAL STARTING POINT - not just inspiration
Keep all FIXED sections exactly as shown (header, sidebar structure, Anthropic colors/fonts, seed controls, action buttons)
Replace only the VARIABLE sections marked in the file's comments (algorithm, parameters, UI controls for your parameters)

DO NOT:

❌ Create HTML from scratch
❌ Invent your own styling or color scheme
❌ Use system fonts or dark themes
❌ Change the sidebar structure

DO:

✅ Copy the template's exact HTML structure
✅ Keep Anthropic branding (Poppins/Lora fonts, light colors, gradient backdrop)
✅ Maintain the sidebar layout (Seed → Parameters → Colors? → Actions)
✅ Replace only the p5.js algorithm and parameter controls

The template is your foundation. Build on it, don't rebuild it.

Create your generative art as if it were gallery-quality, using the algorithmic philosophy. This is computational art that lives and breathes.

TECHNICAL REQUIREMENTS

Seeded Randomness (Art Blocks Pattern):

// ALWAYS use a seed for reproducibility
let seed = 12345; // or hash from user input
randomSeed(seed);
noiseSeed(seed);

Parameter Structure - FOLLOW YOUR PHILOSOPHY:

Your parameters should emerge naturally from your algorithmic philosophy.

Ask yourself: "What qualities of this system can be adjusted?"

let params = {
  seed: 12345,  // Always include seed for reproducibility
  colorPalette: ['#d97757', '#6a9bcc', '#788c5d', '#b0aea5'],  // Anthropic colors
  // Add parameters that control YOUR algorithm:
  // - Quantities (how many?)
  // - Scales (how big? how fast?)
  // - Probabilities (how likely?)
  // - Ratios (what proportions?)
  // - Angles (what direction?)
  // - Thresholds (when does behavior change?)
};

Don't think in terms of "pattern types" - think in terms of the properties your system needs to be tunable.

Core Algorithm - EXPRESS YOUR PHILOSOPHY:

CRITICAL: Your algorithmic philosophy should dictate what you build.

Don't think "which pattern should I use?" - think "how do I express this philosophy through code?"

If your philosophy is about organic emergence, you might use:

Elements that accumulate or grow over time
Random processes constrained by natural rules
Feedback loops and interactions

If your philosophy is about mathematical beauty, you might use:

Geometric relationships and ratios
Trigonometric functions and harmonics
Precise calculations creating unexpected patterns

If your philosophy is about controlled chaos, you might use:

Random variation within strict boundaries
Bifurcation and phase transitions
Order emerging from disorder

The algorithm flows from the philosophy, not from a menu of options.

Let the conceptual essence guide your implementation. Be creative. Be original. Build something that expresses YOUR vision for this particular request.

Canvas Setup: Standard p5.js structure:

function setup() {
  createCanvas(1200, 1200);
  // Initialize your system
}

function draw() {
  // Your generative algorithm
  // Can be static (noLoop) or animated
}

CRAFTSMANSHIP REQUIREMENTS

CRITICAL: Make it feel like a master generative artist created this algorithm through countless iterations. Every parameter should feel carefully tuned. Every pattern should emerge with purpose. This is NOT random noise - this is CONTROLLED CHAOS refined through deep expertise.

Balance: Complexity without visual noise, order without rigidity
Color Harmony: Thoughtful palettes, not random RGB values
Composition: Even in randomness, maintain visual hierarchy and flow
Performance: Smooth execution, optimized for real-time if animated
Reproducibility: Same seed ALWAYS produces identical output

OUTPUT FORMAT

You must output:

Algorithmic Philosophy - As markdown or text explaining your generative aesthetic
Single HTML Artifact - Self-contained interactive generative art built from templates/viewer.html (see STEP 0 and next section)

The HTML artifact contains everything: p5.js (from CDN), your algorithm, parameter controls, and UI - all in one file that works immediately in claude.ai artifacts or any browser. Start from the template file, not from scratch.

INTERACTIVE ARTIFACT CREATION

REMINDER: You should have already read templates/viewer.html (see STEP 0). Use that file as your starting point.

Create a single, self-contained HTML artifact that allows exploration of your generative art. This artifact should work immediately in claude.ai or any browser - no setup required. Everything must be embedded inline.

⚠️ CRITICAL: WHAT'S FIXED VS VARIABLE ⚠️

The templates/viewer.html file is your foundation. It contains the exact structure and styling you need.

FIXED (always include exactly as shown):

Layout structure (header, sidebar, main canvas area)
Anthropic branding (UI colors, fonts, gradients)
Seed section in sidebar:
- Seed display
- Previous/Next buttons
- Random button
- Jump to seed input + Go button
Actions section in sidebar:
- Regenerate button
- Reset button
- Download PNG button

VARIABLE (customize for each artwork):

The entire p5.js algorithm (setup/draw/classes)
The parameters object (define what YOUR art needs)
The Parameters section in sidebar:
- Number of parameter controls
- Parameter names
- Min/max/step values for sliders
- Control types (sliders, inputs, etc.)
Colors section (optional):
- Some art needs color pickers
- Some art might use fixed colors
- Some art might be monochrome (no color controls needed)
- Decide based on YOUR art's needs

Every artwork should have unique parameters and algorithm! The fixed parts provide consistent UX - everything else expresses your unique vision.

REQUIRED FEATURES

1. Parameter Controls

Sliders for numeric parameters (particle count, noise scale, speed, etc.)
Color pickers for palette colors
Real-time updates when parameters change
Reset button to restore defaults

2. Seed Navigation

Display current seed number
"Previous" and "Next" buttons to cycle through seeds
"Random" button for random seed

4. Single Artifact Structure

<!DOCTYPE html>
<html>
<head>
  <!-- p5.js from CDN - always available -->
  <script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.7.0/p5.min.js"></script>
  <style>
    /* All styling inline - clean, minimal */
    /* Canvas on top, controls below */
  </style>
</head>
<body>
  <div id="canvas-container"></div>
  <div id="controls">
    <!-- All parameter controls -->
  </div>
  <script>
    // ALL p5.js code inline here
    // Parameter objects, classes, functions
    // setup() and draw()
    // UI handlers
    // Everything self-contained
  </script>
</body>
</html>

CRITICAL: This is a single artifact. No external files, no imports (except p5.js CDN). Everything inline.

5. Implementation Details - BUILD YOUR SIDEBAR

The sidebar structure:

1. Seed (FIXED) - Always include exactly as shown:

Seed display
Prev/Next/Random/Jump buttons

2. Parameters (VARIABLE) - Create controls for YOUR art:

<div class="control-group">
    <label>Your Parameter Name</label>
    <input type="range" id="yourParam" min="..." max="..." step="..." value="..." oninput="updateParam('yourParam', this.value)">
    <span class="value-display" id="yourParam-value">...</span>
</div>

Add as many control-group divs as you have parameters.

3. Colors (OPTIONAL/VARIABLE) - Include if your art needs adjustable colors:

Add color pickers if users should control palette
Skip this section if your art uses fixed colors
Skip if your art is monochrome

4. Actions (FIXED) - Always include exactly as shown:

Regenerate button
Reset button
Download PNG button

Requirements:

Seed controls must work (prev/next/random/jump/display)
All YOUR parameters must have UI controls
Regenerate, Reset, Download buttons must work
Keep Anthropic branding (UI styling, not art colors)

USING THE ARTIFACT

The HTML artifact works immediately:

In claude.ai: Displayed as an interactive artifact - runs instantly
As a file: Save and open in any browser - no server needed
Sharing: Send the HTML file - it's completely self-contained

VARIATIONS & EXPLORATION

The artifact includes seed navigation by default (prev/next/random buttons), allowing users to explore variations without creating multiple files. If the user wants specific variations highlighted:

Include seed presets (buttons for "Variation 1: Seed 42", "Variation 2: Seed 127", etc.)
Add a "Gallery Mode" that shows thumbnails of multiple seeds side-by-side
All within the same single artifact

This is like creating a series of prints from the same plate - the algorithm is consistent, but each seed reveals different facets of its potential. The interactive nature means users discover their own favorites by exploring the seed space.

THE CREATIVE PROCESS

User request → Your algorithmic philosophy → Your implementation

Each request is unique. Your job is to:

Interpret the user's intent - What aesthetic are they seeking?
Create an algorithmic philosophy (4-6 paragraphs) describing the computational approach
Implement it in code - Build the algorithm that expresses this philosophy
Design appropriate parameters - What should be tunable?
Build matching UI controls - Sliders/inputs for those parameters

The constants:

Anthropic branding (colors, fonts, layout)
Seed navigation (always present)
Self-contained HTML artifact

Everything else is variable:

The algorithm itself
The parameters
The UI controls
The visual outcome

Trust your creativity. Let the philosophy guide the implementation.

RESOURCES

This skill includes helpful templates and documentation:

templates/viewer.html: REQUIRED STARTING POINT for all HTML artifacts.
- YOU MUST READ THIS FILE FIRST using the Read tool (see STEP 0 above)
- This is your foundation - contains the exact structure and Anthropic branding
- Keep unchanged: Layout structure, sidebar organization, Anthropic colors/fonts, seed controls, action buttons
- Replace: The p5.js algorithm (lines 490-730), parameter definitions (line 530), UI controls in Parameters section (lines 418-452)
- The extensive comments in the file mark exactly what to keep vs replace
templates/generator_template.js: Reference for p5.js best practices and code structure principles.
- Shows how to organize parameters, use seeded randomness, structure classes
- NOT a pattern menu - use these principles to build YOUR unique algorithm
- Embed your algorithm inline in the HTML artifact (don't create separate .js files)
README.md: Overview documentation explaining the skill structure and concepts.

Critical reminder:

The template is your STARTING POINT, not inspiration
The algorithm is where you create something unique
Don't copy the flow field example - build what your philosophy demands
But DO keep the exact UI structure and Anthropic branding from the template
