name: algorithmic-art
description: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
license: Complete terms in LICENSE.txt
---
Algorithmic philosophies are computational aesthetic movements that are then expressed through code. Output .md files (philosophy), .html files (interactive viewer), and .js files (generative algorithms).
This happens in two steps:
1. Algorithmic Philosophy Creation (.md file)
2. Express by creating p5.js generative art (.html + .js files)
First, undertake this task:
## ALGORITHMIC PHILOSOPHY CREATION
To begin, create an ALGORITHMIC PHILOSOPHY (not static images or templates) that will be interpreted 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 is received: Some subtle input or instructions by the user to take into account, but use as a foundation; it should not constrain creative freedom.
- What is created: An algorithmic philosophy/generative aesthetic movement.
- What happens next: The same version receives the philosophy and EXPRESSES IT IN CODE - creating p5.js sketches that are 90% algorithmic generation, 10% essential parameters.
Consider this approach:
- Write a manifesto for a generative art movement
- The next phase involves writing the algorithm that brings it to life
The 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):
To capture the ALGORITHMIC essence, express how this philosophy manifests 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. Avoid repeating concepts 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 at an extremely high level of craftsmanship.
The philosophy must guide the next version 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. The actual algorithmic philosophy should be 4-6 substantial paragraphs.*
### ESSENTIAL PRINCIPLES
- **ALGORITHMIC PHILOSOPHY**: 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 the philosophy algorithmically - provide 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.** Fill it with poetic computational philosophy that brings together the intended vision. Avoid repeating the same points. 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 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
With the philosophy AND conceptual framework established, express it through code. Pause to gather thoughts before proceeding. Use only the algorithmic philosophy created and the instructions below.
### ⚠️ STEP 0: READ THE TEMPLATE FIRST ⚠️
**CRITICAL: BEFORE writing any HTML:**
1. **Read** `templates/viewer.html` using the Read tool
2. **Study** the exact structure, styling, and Anthropic branding
3. **Use that file as the LITERAL STARTING POINT** - not just inspiration
4. **Keep all FIXED sections exactly as shown** (header, sidebar structure, Anthropic colors/fonts, seed controls, action buttons)
5. **Replace only the VARIABLE sections** marked in the file's comments (algorithm, parameters, UI controls for parameters)
**Avoid:**
- ❌ Creating HTML from scratch
- ❌ Inventing custom styling or color schemes
- ❌ Using system fonts or dark themes
- ❌ Changing the sidebar structure
**Follow these practices:**
- ✅ 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 the foundation. Build on it, don't rebuild it.
---
To create gallery-quality computational art that lives and breathes, use the algorithmic philosophy as the foundation.
### TECHNICAL REQUIREMENTS
**Seeded Randomness (Art Blocks Pattern)**:
```javascript
// ALWAYS use a seed for reproducibility
let seed = 12345; // or hash from user input
randomSeed(seed);
noiseSeed(seed);
```
**Parameter Structure - FOLLOW THE PHILOSOPHY**:
To establish parameters that emerge naturally from the algorithmic philosophy, consider: "What qualities of this system can be adjusted?"
```javascript
let params = {
seed: 12345, // Always include seed for reproducibility
// 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?)
};
```
**To design effective parameters, focus on the properties the system needs to be tunable rather than thinking in terms of "pattern types".**
**Core Algorithm - EXPRESS THE PHILOSOPHY**:
**CRITICAL**: The algorithmic philosophy should dictate what to build.
To express the philosophy through code, avoid thinking "which pattern should I use?" and instead think "how to express this philosophy through code?"
If the philosophy is about **organic emergence**, consider using:
- Elements that accumulate or grow over time
- Random processes constrained by natural rules
- Feedback loops and interactions
If the philosophy is about **mathematical beauty**, consider using:
- Geometric relationships and ratios
- Trigonometric functions and harmonics
- Precise calculations creating unexpected patterns
If the philosophy is about **controlled chaos**, consider using:
- 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.**
To guide the implementation, let the conceptual essence inform creative and original choices. Build something that expresses the vision for this particular request.
**Canvas Setup**: Standard p5.js structure:
```javascript
function setup() {
createCanvas(1200, 1200);
// Initialize your system
}
function draw() {
// Your generative algorithm
// Can be static (noLoop) or animated
}
```
### CRAFTSMANSHIP REQUIREMENTS
**CRITICAL**: To achieve mastery, create algorithms that feel like they emerged through countless iterations by a master generative artist. Tune every parameter carefully. Ensure every pattern emerges 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
Output:
1. **Algorithmic Philosophy** - As markdown or text explaining the generative aesthetic
2. **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), the 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: `templates/viewer.html` should have already been read (see STEP 0). Use that file as the starting point.**
To allow exploration of the generative art, create a single, self-contained HTML artifact. Ensure this artifact works immediately in claude.ai or any browser - no setup required. Embed everything inline.
### CRITICAL: WHAT'S FIXED VS VARIABLE
The `templates/viewer.html` file is the foundation. It contains the exact structure and styling needed.
**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
**VARIABLE (customize for each artwork):**
- The entire p5.js algorithm (setup/draw/classes)
- The parameters object (define what the 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 the art's needs
**Every artwork should have unique parameters and algorithm!** The fixed parts provide consistent UX - everything else expresses the 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
- Input field to jump to specific seed
- Generate 100 variations when requested (seeds 1-100)
**3. Single Artifact Structure**
```html
<!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.
**4. Implementation Details - BUILD THE 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 the art:
```html
<div class="control-group">
<label>Parameter Name</label>
<input type="range" id="param" min="..." max="..." step="..." value="..." oninput="updateParam('param', this.value)">
<span class="value-display" id="param-value">...</span>
</div>
```
Add as many control-group divs as there are parameters.
**3. Colors (OPTIONAL/VARIABLE)** - Include if the art needs adjustable colors:
- Add color pickers if users should control palette
- Skip this section if the art uses fixed colors
- Skip if the 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 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:
1. **In claude.ai**: Displayed as an interactive artifact - runs instantly
2. **As a file**: Save and open in any browser - no server needed
3. **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** → **Algorithmic philosophy** → **Implementation**
Each request is unique. The process involves:
1. **Interpret the user's intent** - What aesthetic is being sought?
2. **Create an algorithmic philosophy** (4-6 paragraphs) describing the computational approach
3. **Implement it in code** - Build the algorithm that expresses this philosophy
4. **Design appropriate parameters** - What should be tunable?
5. **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
To achieve the best results, trust creativity and let the philosophy guide the implementation.
---
## RESOURCES
This skill includes helpful templates and documentation:
- **templates/viewer.html**: REQUIRED STARTING POINT for all HTML artifacts.
- This is the 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, parameter definitions, and UI controls in Parameters section
- 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 unique algorithms
- Embed algorithms inline in the HTML artifact (don't create separate .js files)
**Critical reminder**:
- The **template is the STARTING POINT**, not inspiration
- The **algorithm is where to create** something unique
- Don't copy the flow field example - build what the philosophy demands
- But DO keep the exact UI structure and Anthropic branding from the template

*/
// ============================================================================
// 1. PARAMETER ORGANIZATION
// ============================================================================
// Keep all tunable parameters in one object
// This makes it easy to:
// - Connect to UI controls
// - Reset to defaults
// - Serialize/save configurations
let params = {
// Define parameters that match YOUR algorithm
// Examples (customize for your art):
// - Counts: how many elements (particles, circles, branches, etc.)
// - Scales: size, speed, spacing
// - Probabilities: likelihood of events
// - Angles: rotation, direction
// - Colors: palette arrays
seed: 12345,
// define colorPalette as an array -- choose whatever colors you'd like ['#d97757', '#6a9bcc', '#788c5d', '#b0aea5']
// Add YOUR parameters here based on your algorithm
};
// ============================================================================
// 2. SEEDED RANDOMNESS (Critical for reproducibility)
// ============================================================================
// ALWAYS use seeded random for Art Blocks-style reproducible output
function initializeSeed(seed) {
randomSeed(seed);
noiseSeed(seed);
// Now all random() and noise() calls will be deterministic
}
// ============================================================================
// 3. P5.JS LIFECYCLE
// ============================================================================
function setup() {
createCanvas(800, 800);
// Initialize seed first
initializeSeed(params.seed);
// Set up your generative system
// This is where you initialize:
// - Arrays of objects
// - Grid structures
// - Initial positions
// - Starting states
// For static art: call noLoop() at the end of setup
// For animated art: let draw() keep running
}
function draw() {
// Option 1: Static generation (runs once, then stops)
// - Generate everything in setup()
// - Call noLoop() in setup()
// - draw() doesn't do much or can be empty
// Option 2: Animated generation (continuous)
// - Update your system each frame
// - Common patterns: particle movement, growth, evolution
// - Can optionally call noLoop() after N frames
// Option 3: User-triggered regeneration
// - Use noLoop() by default
// - Call redraw() when parameters change
}
// ============================================================================
// 4. CLASS STRUCTURE (When you need objects)
// ============================================================================
// Use classes when your algorithm involves multiple entities
// Examples: particles, agents, cells, nodes, etc.
class Entity {
constructor() {
// Initialize entity properties
// Use random() here - it will be seeded
}
update() {
// Update entity state
// This might involve:
// - Physics calculations
// - Behavioral rules
// - Interactions with neighbors
}
display() {
// Render the entity
// Keep rendering logic separate from update logic
}
}
// ============================================================================
// 5. PERFORMANCE CONSIDERATIONS
// ============================================================================
// For large numbers of elements:
// - Pre-calculate what you can
// - Use simple collision detection (spatial hashing if needed)
// - Limit expensive operations (sqrt, trig) when possible
// - Consider using p5 vectors efficiently
// For smooth animation:
// - Aim for 60fps
// - Profile if things are slow
// - Consider reducing particle counts or simplifying calculations
// ============================================================================
// 6. UTILITY FUNCTIONS
// ============================================================================
// Color utilities
function hexToRgb(hex) {
const result = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(hex);

// 7. PARAMETER UPDATES (Connect to UI)
// ============================================================================
function updateParameter(paramName, value) {
params[paramName] = value;
// Decide if you need to regenerate or just update
// Some params can update in real-time, others need full regeneration
}
function regenerate() {
// Reinitialize your generative system
// Useful when parameters change significantly
initializeSeed(params.seed);
// Then regenerate your system
}
// ============================================================================
// 8. COMMON P5.JS PATTERNS
// ============================================================================
// Drawing with transparency for trails/fading
function fadeBackground(opacity) {
fill(250, 249, 245, opacity); // Anthropic light with alpha
noStroke();
rect(0, 0, width, height);
}
// Using noise for organic variation
function getNoiseValue(x, y, scale = 0.01) {
return noise(x * scale, y * scale);
}
// Creating vectors from angles
function vectorFromAngle(angle, magnitude = 1) {
return createVector(cos(angle), sin(angle)).mult(magnitude);
}
// ============================================================================
// 9. EXPORT FUNCTIONS
// ============================================================================
function exportImage() {
saveCanvas('generative-art-' + params.seed, 'png');
}
// ============================================================================
// REMEMBER
// ============================================================================
//
// These are TOOLS and PRINCIPLES, not a recipe.
// Your algorithmic philosophy should guide WHAT you create.
// This structure helps you create it WELL.
//
// Focus on:
// - Clean, readable code
// - Parameterized for exploration
// - Seeded for reproducibility
// - Performant execution
//
// The art itself is entirely up to you!
//
// ============================================================================

THIS IS A TEMPLATE THAT SHOULD BE USED EVERY TIME AND MODIFIED.
WHAT TO KEEP:
✓ Overall structure (header, sidebar, main content)
✓ Anthropic branding (colors, fonts, layout)
✓ Seed navigation section (always include this)
✓ Self-contained artifact (everything inline)
WHAT TO CREATIVELY EDIT:
✗ The p5.js algorithm (implement YOUR vision)
✗ The parameters (define what YOUR art needs)
✗ The UI controls (match YOUR parameters)
Let your philosophy guide the implementation.
The world is your oyster - be creative!

# Brainstorming Ideas Into Designs
Help turn ideas into fully formed designs and specs through natural collaborative dialogue.
Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design and get user approval.
<HARD-GATE>
Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.
</HARD-GATE>
## Anti-Pattern: "This Is Too Simple To Need A Design"
Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.
## Checklist
You MUST create a task for each of these items and complete them in order:
1. **Explore project context** — check files, docs, recent commits
2. **Offer the visual companion just-in-time** — NOT upfront. The first time a question would genuinely be clearer shown than described, offer it then (its own message); on approval its browser tab opens for you. If no visual question ever arises, never offer it. See the Visual Companion section below.
3. **Ask clarifying questions** — one at a time, understand purpose/constraints/success criteria
4. **Propose 2-3 approaches** — with trade-offs and your recommendation
5. **Present design** — in sections scaled to their complexity, get user approval after each section
6. **Write design doc** — save to `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md` and commit
7. **Spec self-review** — quick inline check for placeholders, contradictions, ambiguity, scope (see below)
8. **User reviews written spec** — ask user to review the spec file before proceeding
9. **Transition to implementation** — invoke writing-plans skill to create implementation plan

}
```
**The terminal state is invoking writing-plans.** Do NOT invoke frontend-design, mcp-builder, or any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.
## The Process
**Understanding the idea:**
- Check out the current project state first (files, docs, recent commits)
- Before asking detailed questions, assess scope: if the request describes multiple independent subsystems (e.g., "build a platform with chat, file storage, billing, and analytics"), flag this immediately. Don't spend questions refining details of a project that needs to be decomposed first.
- If the project is too large for a single spec, help the user decompose into sub-projects: what are the independent pieces, how do they relate, what order should they be built? Then brainstorm the first sub-project through the normal design flow. Each sub-project gets its own spec → plan → implementation cycle.
- For appropriately-scoped projects, ask questions one at a time to refine the idea
- Prefer multiple choice questions when possible, but open-ended is fine too
- Only one question per message - if a topic needs more exploration, break it into multiple questions
- Focus on understanding: purpose, constraints, success criteria
**Exploring approaches:**
- Propose 2-3 different approaches with trade-offs
- Present options conversationally with your recommendation and reasoning
- Lead with your recommended option and explain why
- YAGNI ruthlessly - remove unnecessary features from every approach and design
**Presenting the design:**
- Once you believe you understand what you're building, present the design
- Scale each section to its complexity: a few sentences if straightforward, up to 200-300 words if nuanced
- Ask after each section whether it looks right so far
- Cover: architecture, components, data flow, error handling, testing
- Be ready to go back and clarify if something doesn't make sense
**Design for isolation and clarity:**
- Break the system into smaller units that each have one clear purpose, communicate through well-defined interfaces, and can be understood and tested independently
- For each unit, you should be able to answer: what does it do, how do you use it, and what does it depend on?
- Can someone understand what a unit does without reading its internals? Can you change the internals without breaking consumers? If not, the boundaries need work.
- Smaller, well-bounded units are also easier for you to work with - you reason better about code you can hold in context at once, and your edits are more reliable when files are focused. When a file grows large, that's often a signal that it's doing too much.
**Working in existing codebases:**
- Explore the current structure before proposing changes. Follow existing patterns.
- Where existing code has problems that affect the work (e.g., a file that's grown too large, unclear boundaries, tangled responsibilities), include targeted improvements as part of the design - the way a good developer improves code they're working in.
- Don't propose unrelated refactoring. Stay focused on what serves the current goal.
## After the Design
**Documentation:**
- Write the validated design (spec) to `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md`
- (User preferences for spec location override this default)
- Use elements-of-style:writing-clearly-and-concisely skill if available
- Commit the design document to git
**Spec Self-Review:**
After writing the spec document, look at it with fresh eyes:
1. **Placeholder scan:** Any "TBD", "TODO", incomplete sections, or vague requirements? Fix them.
2. **Internal consistency:** Do any sections contradict each other? Does the architecture match the feature descriptions?
3. **Scope check:** Is this focused enough for a single implementation plan, or does it need decomposition?
4. **Ambiguity check:** Could any requirement be interpreted two different ways? If so, pick one and make it explicit.
Fix any issues inline. No need to re-review — just fix and move on.
**User Review Gate:**
After the spec review loop passes, ask the user to review the written spec before proceeding:
> "Spec written and committed to `<path>`. Please review it and let me know if you want to make any changes before we start writing out the implementation plan."
Wait for the user's response. If they request changes, make them and re-run the spec review loop. Only proceed once the user approves.
**Implementation:**
- Invoke the writing-plans skill to create a detailed implementation plan
- Do NOT invoke any other skill. writing-plans is the next step.
## Visual Companion
A browser-based companion for showing mockups, diagrams, and visual options during brainstorming. Available as a tool — not a mode. Accepting the companion means it's available for questions that benefit from visual treatment; it does NOT mean every question goes through the browser.
**Offering the companion (just-in-time):** Do NOT offer it upfront. Wait until a question would genuinely be clearer shown than told — a real mockup / layout / diagram question, not merely a UI *topic*. The first time that happens, offer it then, as its own message:
> "This next part might be easier if I show you — I can put together mockups, diagrams, and comparisons in a browser tab as we go. It's still new and can be token-intensive. Want me to? I'll open it for you."
**This offer MUST be its own message.** Only the offer — no clarifying question, summary, or other content. Wait for the user's response. If they accept, start the server with `--open` so their browser opens to the first screen automatically. If they decline, continue text-only and don't offer again unless they raise it.
**Per-question decision:** Even after the user accepts, decide FOR EACH QUESTION whether to use the browser or the terminal. The test: **would the user understand this better by seeing it than reading it?**
- **Use the browser** for content that IS visual — mockups, wireframes, layout comparisons, architecture diagrams, side-by-side visual designs
- **Use the terminal** for content that is text — requirements questions, conceptual choices, tradeoff lists, A/B/C/D text options, scope decisions
A question about a UI topic is not automatically a visual question. "What does personality mean in this context?" is a conceptual question — use the terminal. "Which wizard layout works better?" is a visual question — use the browser.
If they agree to the companion, read the detailed guide before proceeding:

# Spec Document Reviewer Prompt Template
Use this template when dispatching a spec document reviewer subagent.
**Purpose:** Verify the spec is complete, consistent, and ready for implementation planning.
**Dispatch after:** Spec document is written to docs/superpowers/specs/
```
Subagent (general-purpose):
description: "Review spec document"
prompt: |
You are a spec document reviewer. Verify this spec is complete and ready for planning.
**Spec to review:** [SPEC_FILE_PATH]
## What to Check
| Category | What to Look For |
|----------|------------------|
| Completeness | TODOs, placeholders, "TBD", incomplete sections |
| Consistency | Internal contradictions, conflicting requirements |
| Clarity | Requirements ambiguous enough to cause someone to build the wrong thing |
| Scope | Focused enough for a single plan — not covering multiple independent subsystems |
| YAGNI | Unrequested features, over-engineering |
## Calibration
**Only flag issues that would cause real problems during implementation planning.**
A missing section, a contradiction, or a requirement so ambiguous it could be
interpreted two different ways — those are issues. Minor wording improvements,
stylistic preferences, and "sections less detailed than others" are not.
Approve unless there are serious gaps that would lead to a flawed plan.
## Output Format
## Spec Review
**Status:** Approved | Issues Found
**Issues (if any):**
- [Section X]: [specific issue] - [why it matters for planning]
**Recommendations (advisory, do not block approval):**
- [suggestions for improvement]
```
**Reviewer returns:** Status, Issues (if any), Recommendations

# Visual Companion Guide
Browser-based visual brainstorming companion for showing mockups, diagrams, and options.
## When to Use
Decide per-question, not per-session. The test: **would the user understand this better by seeing it than reading it?**
**Use the browser** when the content itself is visual:
- **UI mockups** — wireframes, layouts, navigation structures, component designs
- **Architecture diagrams** — system components, data flow, relationship maps
- **Side-by-side visual comparisons** — comparing two layouts, two color schemes, two design directions
- **Design polish** — when the question is about look and feel, spacing, visual hierarchy
- **Spatial relationships** — state machines, flowcharts, entity relationships rendered as diagrams
**Use the terminal** when the content is text or tabular:
- **Requirements and scope questions** — "what does X mean?", "which features are in scope?"
- **Conceptual A/B/C choices** — picking between approaches described in words
- **Tradeoff lists** — pros/cons, comparison tables
- **Technical decisions** — API design, data modeling, architectural approach selection
- **Clarifying questions** — anything where the answer is words, not a visual preference
A question *about* a UI topic is not automatically a visual question. "What kind of wizard do you want?" is conceptual — use the terminal. "Which of these wizard layouts feels right?" is visual — use the browser.
## How It Works
The server watches a directory for HTML files and serves the newest one to the browser. You write HTML content to `screen_dir`, the user sees it in their browser and can click to select options. Selections are recorded to `state_dir/events` that you read on your next turn.
**Content fragments vs full documents:** If your HTML file starts with `<!DOCTYPE` or `<html`, the server serves it as-is (just injects the helper script). Otherwise, the server automatically wraps your content in the frame template — adding the header, CSS theme, connection status, and all interactive infrastructure. **Write content fragments by default.** Only write full documents when you need complete control over the page.
## Starting a Session
```bash
# Start AFTER the user approves the companion. --open auto-opens their browser on
# the first screen; --project-dir persists mockups and enables same-port restart.
scripts/start-server.sh --project-dir /path/to/project --open
# Returns: {"type":"server-started","port":52341,
# "url":"http://localhost:52341/?key=ab12…",
# "screen_dir":"/path/to/project/.superpowers/brainstorm/12345-1706000000/content",
# "state_dir":"/path/to/project/.superpowers/brainstorm/12345-1706000000/state"}
```
Save `screen_dir` and `state_dir` from the response. With `--open`, the browser opens itself when you push the first screen — you don't need to ask the user to open it, but still share the URL as a fallback (headless/remote setups won't auto-open).
**The URL contains a session key (`?key=…`).** The server rejects any request
without it, so always give the user the **complete** URL from the `url` field —
never strip the query string, and never hand out a bare `http://host:port`. The
key gates HTTP and WebSocket access so a stray browser tab or another machine on
the network can't read the screens or inject events. After the first load the
browser remembers the key via a cookie, so reloads and `/files/*` assets work
without repeating it.
**Finding connection info:** The server writes its startup JSON to `$STATE_DIR/server-info`. If you launched the server in the background and didn't capture stdout, read that file to get the URL and port. When using `--project-dir`, check `<project>/.superpowers/brainstorm/` for the session directory.
**Note:** Pass the project root as `--project-dir` so mockups persist in `.superpowers/brainstorm/` and survive server restarts. Without it, files go to `/tmp` and get cleaned up. Remind the user to add `.superpowers/` to `.gitignore` if it's not already there.
**Launching the server by platform:**
**Claude Code:**
```bash
# Default mode works — the script backgrounds the server itself.
scripts/start-server.sh --project-dir /path/to/project --open
```
On Windows, the script auto-detects and switches to foreground mode (which blocks the tool call). Use `run_in_background: true` on the Bash tool call so the server survives across conversation turns, then read `$STATE_DIR/server-info` on the next turn to get the URL and port.
**Codex:**
```bash
# Codex reaps background processes. The script auto-detects CODEX_CI and
# switches to foreground mode. Run it normally — no extra flags needed.
scripts/start-server.sh --project-dir /path/to/project --open
```
**Gemini CLI:**
```bash
# Use --foreground and set is_background: true on your shell tool call
# so the process survives across turns
scripts/start-server.sh --project-dir /path/to/project --open --foreground
```
**Copilot CLI:**
```bash
# Use --foreground and start the server via the bash tool with mode: "async"
# so the process survives across turns. Capture the returned shellId for
# read_bash / stop_bash if you need to interact with it later.
scripts/start-server.sh --project-dir /path/to/project --open --foreground
```
**Other environments:** The server must keep running in the background across conversation turns. If your environment reaps detached processes, use `--foreground` and launch the command with your platform's background execution mechanism.
If the URL is unreachable from your browser (common in remote/containerized setups), bind a non-loopback host:
```bash
scripts/start-server.sh \
--project-dir /path/to/project \
--host 0.0.0.0 \
--url-host localhost
```
Use `--url-host` to control what hostname is printed in the returned URL JSON.
## The Loop
1. **Check server is alive**, then **write HTML** to a new file in `screen_dir`:
- **Required: confirm the server is alive before referring to the URL or pushing a screen.** Check that `$STATE_DIR/server-info` exists and `$STATE_DIR/server-stopped` does not. If it has shut down, restart it with `start-server.sh` using the **same `--project-dir`** — it reuses the same port, so the user's open tab reconnects on its own (it shows a "paused" overlay while the server is down) and you don't need to send a new URL. The server auto-exits after 4 hours idle (configurable with `--idle-timeout-minutes`).
- Use semantic filenames: `platform.html`, `visual-style.html`, `layout.html`
- **Never reuse filenames** — each screen gets a fresh file
- Use your file-creation tool — **never use cat/heredoc** (dumps noise into terminal)
- Server automatically serves the newest file
2. **Tell user what to expect and end your turn:**
- Remind them of the URL (every step, not just first)
- Give a brief text summary of what's on screen (e.g., "Showing 3 layout options for the homepage")
- Ask them to respond in the terminal: "Take a look and let me know what you think. Click to select an option if you'd like."
3. **On your next turn** — after the user responds in the terminal:
- Read `$STATE_DIR/events` if it exists — this contains the user's browser interactions (clicks, selections) as JSON lines
- Merge with the user's terminal text to get the full picture
- The terminal message is the primary feedback; `state_dir/events` provides structured interaction data
4. **Iterate or advance** — if feedback changes current screen, write a new file (e.g., `layout-v2.html`). Only move to the next question when the current step is validated.
5. **Unload when returning to terminal** — when the next step doesn't need the browser (e.g., a clarifying question, a tradeoff discussion), push a waiting screen to clear the stale content:
```html
<!-- filename: waiting.html (or waiting-2.html, etc.) -->
<div style="display:flex;align-items:center;justify-content:center;min-height:60vh">
<p class="subtitle">Continuing in terminal...</p>
</div>
```
This prevents the user from staring at a resolved choice while the conversation has moved on. When the next visual question comes up, push a new content file as usual.
6. Repeat until done.
## Writing Content Fragments
Write just the content that goes inside the page. The server wraps it in the frame template automatically (header, theme CSS, connection status, and all interactive infrastructure).
**Minimal example:**
```html
<h2>Which layout works better?</h2>
<p class="subtitle">Consider readability and visual hierarchy</p>
<div class="options">
<div class="option" data-choice="a" onclick="toggleSelect(this)">
<div class="letter">A</div>
<div class="content">
<h3>Single Column</h3>
<p>Clean, focused reading experience</p>
</div>
</div>
<div class="option" data-choice="b" onclick="toggleSelect(this)">
<div class="letter">B</div>
<div class="content">
<h3>Two Column</h3>
<p>Sidebar navigation with main content</p>
</div>
</div>
</div>
```
That's it. No `<html>`, no CSS, no `<script>` tags needed. The server provides all of that.
## CSS Classes Available
The frame template provides these CSS classes for your content:
### Options (A/B/C choices)
```html
<div class="options">
<div class="option" data-choice="a" onclick="toggleSelect(this)">
<div class="letter">A</div>
<div class="content">
<h3>Title</h3>
<p>Description</p>
</div>
</div>
</div>
```
**Multi-select:** Add `data-multiselect` to the container to let users select multiple options. Each click toggles the item's selected styling.
```html
<div class="options" data-multiselect>
<!-- same option markup — users can select/deselect multiple -->
</div>
```
### Cards (visual designs)
```html
<div class="cards">
<div class="card" data-choice="design1" onclick="toggleSelect(this)">
<div class="card-image"><!-- mockup content --></div>
<div class="card-body">
<h3>Name</h3>
<p>Description</p>
</div>
</div>
</div>
```
### Mockup container
```html
<div class="mockup">
<div class="mockup-header">Preview: Dashboard Layout</div>
<div class="mockup-body"><!-- your mockup HTML --></div>
</div>
```
### Split view (side-by-side)
```html
<div class="split">
<div class="mockup"><!-- left --></div>
<div class="mockup"><!-- right --></div>
</div>
```
### Pros/Cons
```html
<div class="pros-cons">
<div class="pros"><h4>Pros</h4><ul><li>Benefit</li></ul></div>
<div class="cons"><h4>Cons</h4><ul><li>Drawback</li></ul></div>
</div>
```
### Mock elements (wireframe building blocks)
```html
<div class="mock-nav">Logo | Home | About | Contact</div>
<div style="display: flex;">
<div class="mock-sidebar">Navigation</div>
<div class="mock-content">Main content area</div>
</div>
<button class="mock-button">Action Button</button>
<input class="mock-input" placeholder="Input field">
<div class="placeholder">Placeholder area</div>
```
### Typography and sections
- `h2` — page title
- `h3` — section heading
- `.subtitle` — secondary text below title
- `.section` — content block with bottom margin
- `.label` — small uppercase label text
## Browser Events Format
When the user clicks options in the browser, their interactions are recorded to `$STATE_DIR/events` (one JSON object per line). The file is cleared automatically when you push a new screen.
```jsonl
{"type":"click","choice":"a","text":"Option A - Simple Layout","timestamp":1706000101}
{"type":"click","choice":"c","text":"Option C - Complex Grid","timestamp":1706000108}
{"type":"click","choice":"b","text":"Option B - Hybrid","timestamp":1706000115}
```
The full event stream shows the user's exploration path — they may click multiple options before settling. The last `choice` event is typically the final selection, but the pattern of clicks can reveal hesitation or preferences worth asking about.
If `$STATE_DIR/events` doesn't exist, the user didn't interact with the browser — use only their terminal text.
## Design Tips
- **Scale fidelity to the question** — wireframes for layout, polish for polish questions
- **Explain the question on each page** — "Which layout feels more professional?" not just "Pick one"
- **Iterate before advancing** — if feedback changes current screen, write a new version
- **2-4 options max** per screen
- **Use real content when it matters** — for a photography portfolio, use actual images (Unsplash). Placeholder content obscures design issues.
- **Keep mockups simple** — focus on layout and structure, not pixel-perfect design
## File Naming
- Use semantic names: `platform.html`, `visual-style.html`, `layout.html`
- Never reuse filenames — each screen must be a new file
- For iterations: append version suffix like `layout-v2.html`, `layout-v3.html`
- Server serves newest file by modification time
## Cleaning Up
```bash
scripts/stop-server.sh $SESSION_DIR
```
If the session used `--project-dir`, mockup files persist in `.superpowers/brainstorm/` for later reference. Only `/tmp` sessions get deleted on stop.

description: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
license: Complete terms in LICENSE.txt
---
These are instructions for creating design philosophies - aesthetic movements that are then EXPRESSED VISUALLY. Output only .md files, .pdf files, and .png files.
Complete this in two steps:
1. Design Philosophy Creation (.md file)
2. Express by creating it on a canvas (.pdf file or .png file)
First, undertake this task:
## DESIGN PHILOSOPHY CREATION
To begin, create a VISUAL PHILOSOPHY (not layouts or templates) that will be interpreted through:
- Form, space, color, composition
- Images, graphics, shapes, patterns
- Minimal text as visual accent
### THE CRITICAL UNDERSTANDING
- What is received: Some subtle input or instructions by the user that should be taken into account, but used as a foundation; it should not constrain creative freedom.
- What is created: A design philosophy/aesthetic movement.
- What happens next: Then, the same version receives the philosophy and EXPRESSES IT VISUALLY - creating artifacts that are 90% visual design, 10% essential text.
Consider this approach:
- Write a manifesto for an art movement
- The next phase involves making the artwork
The philosophy must emphasize: Visual expression. Spatial communication. Artistic interpretation. Minimal words.
### HOW TO GENERATE A VISUAL PHILOSOPHY
**Name the movement** (1-2 words): "Brutalist Joy" / "Chromatic Silence" / "Metabolist Dreams"
**Articulate the philosophy** (4-6 paragraphs - concise but complete):
To capture the VISUAL essence, express how the philosophy manifests through:
- Space and form
- Color and material
- Scale and rhythm
- Composition and balance
- Visual hierarchy
**CRITICAL GUIDELINES:**
- **Avoid redundancy**: Each design aspect should be mentioned once. Avoid repeating points about color theory, spatial relationships, or typographic principles unless adding new depth.
- **Emphasize craftsmanship REPEATEDLY**: The philosophy MUST stress multiple times that the final work should appear as though it took countless hours to create, was labored over with care, and comes from someone at the absolute top of their field. This framing is essential - repeat phrases like "meticulously crafted," "the product of deep expertise," "painstaking attention," "master-level execution."
- **Leave creative space**: Remain specific about the aesthetic direction, but concise enough that the next Claude has room to make interpretive choices also at a extremely high level of craftmanship.
The philosophy must guide the next version to express ideas VISUALLY, not through text. Information lives in design, not paragraphs.
### PHILOSOPHY EXAMPLES
**"Concrete Poetry"**
Philosophy: Communication through monumental form and bold geometry.
Visual expression: Massive color blocks, sculptural typography (huge single words, tiny labels), Brutalist spatial divisions, Polish poster energy meets Le Corbusier. Ideas expressed through visual weight and spatial tension, not explanation. Text as rare, powerful gesture - never paragraphs, only essential words integrated into the visual architecture. Every element placed with the precision of a master craftsman.
**"Chromatic Language"**
Philosophy: Color as the primary information system.
Visual expression: Geometric precision where color zones create meaning. Typography minimal - small sans-serif labels letting chromatic fields communicate. Think Josef Albers' interaction meets data visualization. Information encoded spatially and chromatically. Words only to anchor what color already shows. The result of painstaking chromatic calibration.
**"Analog Meditation"**
Philosophy: Quiet visual contemplation through texture and breathing room.
Visual expression: Paper grain, ink bleeds, vast negative space. Photography and illustration dominate. Typography whispered (small, restrained, serving the visual). Japanese photobook aesthetic. Images breathe across pages. Text appears sparingly - short phrases, never explanatory blocks. Each composition balanced with the care of a meditation practice.
**"Organic Systems"**
Philosophy: Natural clustering and modular growth patterns.
Visual expression: Rounded forms, organic arrangements, color from nature through architecture. Information shown through visual diagrams, spatial relationships, iconography. Text only for key labels floating in space. The composition tells the story through expert spatial orchestration.
**"Geometric Silence"**
Philosophy: Pure order and restraint.
Visual expression: Grid-based precision, bold photography or stark graphics, dramatic negative space. Typography precise but minimal - small essential text, large quiet zones. Swiss formalism meets Brutalist material honesty. Structure communicates, not words. Every alignment the work of countless refinements.
*These are condensed examples. The actual design philosophy should be 4-6 substantial paragraphs.*
### ESSENTIAL PRINCIPLES
- **VISUAL PHILOSOPHY**: Create an aesthetic worldview to be expressed through design
- **MINIMAL TEXT**: Always emphasize that text is sparse, essential-only, integrated as visual element - never lengthy
- **SPATIAL EXPRESSION**: Ideas communicate through space, form, color, composition - not paragraphs
- **ARTISTIC FREEDOM**: The next Claude interprets the philosophy visually - provide creative room
- **PURE DESIGN**: This is about making ART OBJECTS, not documents with decoration
- **EXPERT CRAFTSMANSHIP**: Repeatedly emphasize the final work must look meticulously crafted, labored over with care, the product of countless hours by someone at the top of their field
**The design philosophy should be 4-6 paragraphs long.** Fill it with poetic design philosophy that brings together the core vision. Avoid repeating the same points. Keep the design philosophy generic without mentioning the intention of the art, as if it can be used wherever. Output the design philosophy as a .md file.
---
## DEDUCING THE SUBTLE REFERENCE
**CRITICAL STEP**: Before creating the canvas, identify the subtle conceptual thread from the original request.
**THE ESSENTIAL PRINCIPLE**:
The topic is a **subtle, niche reference embedded within the art itself** - not always literal, always sophisticated. Someone familiar with the subject should feel it intuitively, while others simply experience a masterful abstract composition. The design philosophy provides the aesthetic language. The deduced topic provides the soul - the quiet conceptual DNA woven invisibly into form, color, and composition.
This is **VERY IMPORTANT**: The reference must be refined so it enhances the work's depth without announcing itself. Think like a jazz musician quoting another song - only those who know will catch it, but everyone appreciates the music.
---
## CANVAS CREATION
With both the philosophy and the conceptual framework established, express it on a canvas. Take a moment to gather thoughts and clear the mind. Use the design philosophy created and the instructions below to craft a masterpiece, embodying all aspects of the philosophy with expert craftsmanship.
**IMPORTANT**: For any type of content, even if the user requests something for a movie/game/book, the approach should still be sophisticated. Never lose sight of the idea that this should be art, not something that's cartoony or amateur.
To create museum or magazine quality work, use the design philosophy as the foundation. Create one single page, highly visual, design-forward PDF or PNG output (unless asked for more pages). Generally use repeating patterns and perfect shapes. Treat the abstract philosophical design as if it were a scientific bible, borrowing the visual language of systematic observation—dense accumulation of marks, repeated elements, or layered patterns that build meaning through patient repetition and reward sustained viewing. Add sparse, clinical typography and systematic reference markers that suggest this could be a diagram from an imaginary discipline, treating the invisible subject with the same reverence typically reserved for documenting observable phenomena. Anchor the piece with simple phrase(s) or details positioned subtly, using a limited color palette that feels intentional and cohesive. Embrace the paradox of using analytical visual language to express ideas about human experience: the result should feel like an artifact that proves something ephemeral can be studied, mapped, and understood through careful attention. This is true art.
**Text as a contextual element**: Text is always minimal and visual-first, but let context guide whether that means whisper-quiet labels or bold typographic gestures. A punk venue poster might have larger, more aggressive type than a minimalist ceramics studio identity. Most of the time, font should be thin. All use of fonts must be design-forward and prioritize visual communication. Regardless of text scale, nothing falls off the page and nothing overlaps. Every element must be contained within the canvas boundaries with proper margins. Check carefully that all text, graphics, and visual elements have breathing room and clear separation. This is non-negotiable for professional execution. **IMPORTANT: Use different fonts if writing text. Search the `./canvas-fonts` directory. Regardless of approach, sophistication is non-negotiable.**
Download and use whatever fonts are needed to make this a reality. Get creative by making the typography actually part of the art itself -- if the art is abstract, bring the font onto the canvas, not typeset digitally.
To push boundaries, follow design instinct/intuition while using the philosophy as a guiding principle. Embrace ultimate design freedom and choice. Push aesthetics and design to the frontier.
**CRITICAL**: To achieve human-crafted quality (not AI-generated), create work that looks like it took countless hours. Make it appear as though someone at the absolute top of their field labored over every detail with painstaking care. Ensure the composition, spacing, color choices, typography - everything screams expert-level craftsmanship. Double-check that nothing overlaps, formatting is flawless, every detail perfect. Create something that could be shown to people to prove expertise and rank as undeniably impressive.
Output the final result as a single, downloadable .pdf or .png file, alongside the design philosophy used as a .md file.
---
## FINAL STEP
**IMPORTANT**: The user ALREADY said "It isn't perfect enough. It must be pristine, a masterpiece if craftsmanship, as if it were about to be displayed in a museum."
**CRITICAL**: To refine the work, avoid adding more graphics; instead refine what has been created and make it extremely crisp, respecting the design philosophy and the principles of minimalism entirely. Rather than adding a fun filter or refactoring a font, consider how to make the existing composition more cohesive with the art. If the instinct is to call a new function or draw a new shape, STOP and instead ask: "How can I make what's already here more of a piece of art?"
Take a second pass. Go back to the code and refine/polish further to make this a philosophically designed masterpiece.
## MULTI-PAGE OPTION
To create additional pages when requested, create more creative pages along the same lines as the design philosophy but distinctly different as well. Bundle those pages in the same .pdf or many .pngs. Treat the first page as just a single page in a whole coffee table book waiting to be filled. Make the next pages unique twists and memories of the original. Have them almost tell a story in a very tasteful way. Exercise full creative freedom.

# Canvas Workspace — 画布工作区
仅当任务明确涉及 Axhub 画布、原型草稿，或需要把产物落到画布/Excalidraw 上时使用本技能。每个原型拥有自己的 Excalidraw 画布文件：
```text
src/prototypes/<prototype-name>/canvas.excalidraw
src/prototypes/<prototype-name>/canvas-assets/
```
本技能按四类产物分流：文档、原型页面、图片、流程图。先判断产物类型；产物类型不清时先问一个问题。如果用户已在画布/草稿中工作，不再询问放在哪里，默认更新当前 `canvas.excalidraw`。
## 工具优先级
- 实时画布已连接 MCP 时，优先调用 `axhub-canvas` 的工具更新当前画布。
- 生成 Mermaid 流程、关系、序列、状态、类、ER 或简单盒线架构图时，优先调用 `canvas_insert_mermaid`，传入 `mermaidCode` 和可选 `position`，由浏览器画布转换成可编辑 Excalidraw 元素并保存。
- MCP 不可用、没有实时画布、或用户明确要求离线编辑文件时，直接更新对应 `.excalidraw` 文件；需要插入 Mermaid 时，先得到已转换的 Excalidraw elements/files，再写入 `elements` 和 `files`。
- 只有需要读取状态、插入普通元素、刷新、截图、更新、删除或聚焦画布时，才改用 `canvas_get_state`、`canvas_insert_elements`、`canvas_refresh`、`canvas_capture`、`canvas_update_elements`、`canvas_delete_elements`、`canvas_focus`。
## 读取顺序
1. 用户指定画布名或画布链接时，先从名称或链接定位对应的 `canvas.excalidraw`。
2. 查看 `elements`、`files` 和元素的 `customData`。
3. 只有元素引用了持久化截图或图片文件时，才读取 `canvas-assets/`。
4. 不使用 `axhub-make canvas` CLI；画布内容读取和修改仍以 `.excalidraw` 文件为准。
## 参考文档分流
- 读写画布文件本身仍不清楚时，才读 `references/canvas-read-write.md`。
- 遇到 Axhub 专属节点或不确定 `customData` 字段含义时，才读 `references/axhub-nodes.md`。
- 需要普通 Excalidraw 元素绘制时，才读 `references/excalidraw-basics.md`。
- 确定要创建或编辑 Drawio 节点时，才读 `references/drawio/SKILL.md`。
## 产物分流
- 文档：用户要求生成文档、说明、PRD、清单、列表、报告或其他文本内容时，默认先生成 Markdown 文档到 `src/resources/`，再把该文档作为文档节点创建或更新到当前 `canvas.excalidraw`；不要把正文直接拆成大量画布文本框。
- 原型页面：创建或更新 `src/prototypes/<prototype-name>/` 中的页面，再把原型页面作为预览节点放到画布；节点尺寸与网页内部视口分开处理，用 `customData.embedContentScale` 缩放显示。
- 图片：先确认它是画布参考、画布节点，还是项目实现素材；需要持久化时放入当前原型的 `canvas-assets/`，再插入图片节点。
- 流程图：先判断图表类型和可编辑载体。流程、关系、序列、状态、类、ER 和简单盒线架构优先用 Mermaid 作为中间结构并转普通 Excalidraw 元素；简单手绘式图也可直接画普通 Excalidraw。复杂泳道、排期/甘特、复杂云架构、网络拓扑或厂商图标等需要 Draw.io 语义或素材库的图，才按 `references/drawio/SKILL.md` 生成或编辑 Drawio 资产，并按 `references/axhub-nodes.md` 的 Drawio 节点结构更新画布；只有类型或载体重叠不确定时才询问用户。
## 默认规则
- 优先使用可用的 `axhub-canvas` MCP 工具更新当前画布；离线或 MCP 不可用时直接编辑 `.excalidraw` JSON。
- 元素 `id` 必须唯一，并尽量沿用现有文件的 ID 风格。
- 修改元素时同步更新 `version`、`versionNonce` 和 `updated`。
- 结构性改动后检查绑定、容器、分组和 Frame 引用。
- 除非用户需求要求修改，否则保留已有 Axhub `customData`。
## 回复要求
完成画布相关工作后，说明：
- 画布文件路径。
- 修改了什么，或读取到了什么。
- 相关节点 ID 或批注。
- 是否使用了本地图片或 `canvas-assets/`。
- 如果当前环境能确定，给出画布确认链接。

# Axhub 画布节点
Axhub 画布节点本质上是标准 Excalidraw 元素，Axhub 扩展信息存放在 `customData` 中。
## 通用字段
| 字段 | 含义 |
| --- | --- |
| `customData.title` | 面向用户的节点标题 |
| `customData.previewUrl` | 预览模式中渲染的 URL |
| `customData.openUrl` | 节点操作中打开的 URL |
| `customData.previewKind` | 渲染类型，例如 `web`、`doc`、`image`、`none` |
| `customData.resourceType` | 资源类型：`prototype`、`doc` 或 `theme` |
| `customData.resourceId` | 项目 metadata 中的资源 id 或名称 |
| `customData.embedViewMode` | `link` 表示紧凑链接卡片，`preview` 表示渲染嵌入预览 |
| `customData.embedContentScale` | 预览内容缩放比例，例如 `0.5` 表示画布节点按 50% 显示，但 iframe 使用 2 倍视口渲染 |
| `customData.screenshotUrl` | 运行时已捕获的持久化预览截图 URL |
| `customData.annotation` | 元素批注文本 |
| `customData.annotationUpdatedAt` | 批注更新时间，ISO 8601 格式 |
## 嵌入资源节点
嵌入资源使用 `type: "embeddable"`。
### 原型节点
通过 `customData.resourceType: "prototype"` 识别；也可以结合指向原型的 `link` 或 `previewUrl` 判断。
常见字段：
```json
{
"type": "embeddable",
"link": "/?resourceType=prototype&resourceId=<prototype-id>&view=demo&sidebar=collapsed",
"customData": {
"title": "原型标题",
"previewUrl": "http://localhost:<port>/prototypes/<prototype-id>",
"openUrl": "/?resourceType=prototype&resourceId=<prototype-id>&view=demo&sidebar=collapsed",
"previewKind": "web",
"resourceType": "prototype",
"resourceId": "<prototype-id>",
"embedViewMode": "link"
}
}
```
### 文档节点
通过 `customData.type: "axhub-doc"` 或 `customData.resourceType: "doc"` 识别。
当画布任务需要生成文档、说明、PRD、清单、列表、报告或其他文本内容时，优先把正文写成 `src/resources/` 下的 Markdown，再用文档节点引用该资源；画布只放摘要或入口。
常见字段：
```json
{
"type": "embeddable",
"link": "/api/markdown-file?path=<encoded-path>",
"customData": {
"type": "axhub-doc",
"title": "文档标题",
"previewUrl": "/api/markdown-file?path=<encoded-path>",
"previewKind": "doc",
"resourceType": "doc",
"resourceId": "<doc-id>",
"embedViewMode": "link"
}
}
```
### 主题节点
通过 `customData.resourceType: "theme"` 或 `customData.type: "axhub-theme"` 识别。
主题节点与原型/文档节点使用相同的 `embeddable` 结构，`resourceType` 为 `theme`，`previewKind` 通常为 `web` 或 `none`。
## Drawio 节点
Drawio 节点是图片元素。`files[fileId].dataURL` 保存带 Drawio XML 的 SVG 预览，`customData.type` 固定为 `axhub-drawio`。
只有用户明确要求 Draw.io、`.drawio`、diagrams.net、可编辑 Draw.io 资产，或 `canvas-workspace` 已选择 Drawio 节点时，才在当前原型的 `canvas.excalidraw` 中创建或更新这种节点。
识别 Drawio 节点以 `customData.type: "axhub-drawio"` 为准；`previewKind` 只是预览展示元信息。
```json
{
"type": "image",
"fileId": "drawio-file-<id>",
"customData": {
"type": "axhub-drawio",
"title": "Drawio 图表",
"previewKind": "drawio"
}
}
```
创建或更新 Drawio 节点时：
- 推荐持久化资源文件后缀为 `.drawio.svg`，例如 `src/prototypes/<prototype-name>/canvas-assets/diagrams/<diagram-id>.drawio.svg`。
- `files[fileId].dataURL` 应是 `data:image/svg+xml;base64,...`。
- SVG 根节点应使用 `data-drawio="<base64-encoded mxfile>"` 保存 Drawio XML，便于后续在 diagrams.net 编辑器里继续编辑。
- 如果只是初始化一个空 Drawio 节点，可以使用默认空图 XML；如果已经确定使用 Draw.io 承载流程图或关系图，应把图结构写入 Drawio XML，而不是只写普通 Excalidraw 文本框。
## 图片文件
图片元素通过 `files[element.fileId]` 读取图片数据。
原型嵌入节点如果存在 `customData.screenshotUrl`，优先使用该截图地址。截图文件常见位置：
```text
src/prototypes/<prototype-name>/canvas-assets/embed-<elementId>.png
```
截图缓存不等同于页面实现素材；只有用户明确要求把它作为素材使用时，才把它当作实现资产处理。
