+# Excalidraw Diagram Generator
+
+A skill for generating Excalidraw-format diagrams from natural language descriptions. This skill helps create visual representations of processes, systems, relationships, and ideas without manual drawing.
+
+## When to Use This Skill
+
+Use this skill when users request:
+
+- "Create a diagram showing..."
+- "Make a flowchart for..."
+- "Visualize the process of..."
+- "Draw the system architecture of..."
+- "Generate a mind map about..."
+- "Create an Excalidraw file for..."
+- "Show the relationship between..."
+- "Diagram the workflow of..."
+
+**Supported diagram types:**
+- 📊 **Flowcharts**: Sequential processes, workflows, decision trees
+- 🔗 **Relationship Diagrams**: Entity relationships, system components, dependencies
+- 🧠 **Mind Maps**: Concept hierarchies, brainstorming results, topic organization
+- 🏗️ **Architecture Diagrams**: System design, module interactions, data flow
+- 📈 **Data Flow Diagrams (DFD)**: Data flow visualization, data transformation processes
+- 🏊 **Business Flow (Swimlane)**: Cross-functional workflows, actor-based process flows
+- 📦 **Class Diagrams**: Object-oriented design, class structures and relationships
+- 🔄 **Sequence Diagrams**: Object interactions over time, message flows
+- 🗃️ **ER Diagrams**: Database entity relationships, data models
+
+## Prerequisites
+
+- Clear description of what should be visualized
+- Identification of key entities, steps, or concepts
+- Understanding of relationships or flow between elements
+
+## Step-by-Step Workflow
+
+### Step 1: Understand the Request
+
+Analyze the user's description to determine:
+1. **Diagram type** (flowchart, relationship, mind map, architecture)
+2. **Key elements** (entities, steps, concepts)
+3. **Relationships** (flow, connections, hierarchy)
+4. **Complexity** (number of elements)
+
+### Step 2: Choose the Appropriate Diagram Type
+
+| User Intent | Diagram Type | Example Keywords |
+|-------------|--------------|------------------|
+| Process flow, steps, procedures | **Flowchart** | "workflow", "process", "steps", "procedure" |
+| Connections, dependencies, associations | **Relationship Diagram** | "relationship", "connections", "dependencies", "structure" |
+| Concept hierarchy, brainstorming | **Mind Map** | "mind map", "concepts", "ideas", "breakdown" |
+| System design, components | **Architecture Diagram** | "architecture", "system", "components", "modules" |
+| Data flow, transformation processes | **Data Flow Diagram (DFD)** | "data flow", "data processing", "data transformation" |
+| Cross-functional processes, actor responsibilities | **Business Flow (Swimlane)** | "business process", "swimlane", "actors", "responsibilities" |
+| Object-oriented design, class structures | **Class Diagram** | "class", "inheritance", "OOP", "object model" |
+| Interaction sequences, message flows | **Sequence Diagram** | "sequence", "interaction", "messages", "timeline" |
+| Database design, entity relationships | **ER Diagram** | "database", "entity", "relationship", "data model" |
+
+### Step 3: Extract Structured Information
+
+**For Flowcharts:**
+- List of sequential steps
+- Decision points (if any)
+- Start and end points
+
+**For Relationship Diagrams:**
+- Entities/nodes (name + optional description)
+- Relationships between entities (from → to, with label)
+
+**For Mind Maps:**
+- Central topic
+- Main branches (3-6 recommended)
+- Sub-topics for each branch (optional)
+
+**For Data Flow Diagrams (DFD):**
+- Data sources and destinations (external entities)
+- Processes (data transformations)
+- Data stores (databases, files)
+- Data flows (arrows showing data movement from left-to-right or from top-left to bottom-right)
+- **Important**: Do not represent process order, only data flow
+
+**For Business Flow (Swimlane):**
+- Actors/roles (departments, systems, people) - displayed as header columns
+- Process lanes (vertical lanes under each actor)
+- Process boxes (activities within each lane)
+- Flow arrows (connecting process boxes, including cross-lane handoffs)
+
+**For Class Diagrams:**
+- Classes with names
+- Attributes with visibility (+, -, #)
+- Methods with visibility and parameters
+- Relationships: inheritance (solid line + white triangle), implementation (dashed line + white triangle), association (solid line), dependency (dashed line), aggregation (solid line + white diamond), composition (solid line + filled diamond)
+- Multiplicity notations (1, 0..1, 1..*, *)
+
+**For Sequence Diagrams:**
+- Objects/actors (arranged horizontally at top)
+- Lifelines (vertical lines from each object)
+- Messages (horizontal arrows between lifelines)
+- Synchronous messages (solid arrow), asynchronous messages (dashed arrow)
+- Return values (dashed arrows)
+- Activation boxes (rectangles on lifelines during execution)
+- Time flows from top to bottom
+
+**For ER Diagrams:**
+- Entities (rectangles with entity names)
+- Attributes (listed inside entities)
+- Primary keys (underlined or marked with PK)
+- Foreign keys (marked with FK)
+- Relationships (lines connecting entities)
+- Cardinality: 1:1 (one-to-one), 1:N (one-to-many), N:M (many-to-many)
+- Junction/associative entities for many-to-many relationships (dashed rectangles)
+
+### Step 4: Generate the Excalidraw JSON
+
+Create the `.excalidraw` file with appropriate elements:
+
+**Available element types:**
+- `rectangle`: Boxes for entities, steps, concepts
+- `ellipse`: Alternative shapes for emphasis
+- `diamond`: Decision points
+- `arrow`: Directional connections
+- `text`: Labels and annotations
+
+**Key properties to set:**
+- **Position**: `x`, `y` coordinates
+- **Size**: `width`, `height`
+- **Style**: `strokeColor`, `backgroundColor`, `fillStyle`
+- **Font**: `fontFamily: 5` (Excalifont - **required for all text elements**)
+- **Text**: Embedded text for labels
+- **Connections**: `points` array for arrows
+
+**Important**: All text elements must use `fontFamily: 5` (Excalifont) for consistent visual appearance.
+
+### Step 5: Format the Output
+
+Structure the complete Excalidraw file:
+
+```json
+{
+  "type": "excalidraw",
+  "version": 2,
+  "source": "https://excalidraw.com",
+  "elements": [
+    // Array of diagram elements
+  ],
+  "appState": {
+    "viewBackgroundColor": "#ffffff",
+    "gridSize": 20
+  },
+  "files": {}
+}
+```
+
+### Step 6: Save and Provide Instructions
+
+1. Save as `<descriptive-name>.excalidraw`
+2. Inform user how to open:
+   - Visit https://excalidraw.com
+   - Click "Open" or drag-and-drop the file
+   - Or use Excalidraw VS Code extension
+
+## Best Practices
+
+### Element Count Guidelines
+
+| Diagram Type | Recommended Count | Maximum |
+|--------------|-------------------|---------|
+| Flowchart steps | 3-10 | 15 |
+| Relationship entities | 3-8 | 12 |
+| Mind map branches | 4-6 | 8 |
+| Mind map sub-topics per branch | 2-4 | 6 |
+
+### Layout Tips
+
+1. **Start positions**: Center important elements, use consistent spacing
+2. **Spacing**: 
+   - Horizontal gap: 200-300px between elements
+   - Vertical gap: 100-150px between rows
+3. **Colors**: Use consistent color scheme
+   - Primary elements: Light blue (`#a5d8ff`)
+   - Secondary elements: Light green (`#b2f2bb`)
+   - Important/Central: Yellow (`#ffd43b`)
+   - Alerts/Warnings: Light red (`#ffc9c9`)
+4. **Text sizing**: 16-24px for readability
+5. **Font**: Always use `fontFamily: 5` (Excalifont) for all text elements
+6. **Arrow style**: Use straight arrows for simple flows, curved for complex relationships
+
+### Complexity Management
+
+**If user request has too many elements:**
+- Suggest breaking into multiple diagrams
+- Focus on main elements first
+- Offer to create detailed sub-diagrams
+
+**Example response:**
+```
+"Your request includes 15 components. For clarity, I recommend:
+1. High-level architecture diagram (6 main components)
+2. Detailed diagram for each subsystem
+
+Would you like me to start with the high-level view?"
+```
+
+## Example Prompts and Responses
+
+### Example 1: Simple Flowchart
+
+**User:** "Create a flowchart for user registration"
+
+**Agent generates:**
+1. Extract steps: "Enter email" → "Verify email" → "Set password" → "Complete"
+2. Create flowchart with 4 rectangles + 3 arrows
+3. Save as `user-registration-flow.excalidraw`
+
+### Example 2: Relationship Diagram
+
+**User:** "Diagram the relationship between User, Post, and Comment entities"
+
+**Agent generates:**
+1. Entities: User, Post, Comment
+2. Relationships: User → Post ("creates"), User → Comment ("writes"), Post → Comment ("contains")
+3. Save as `user-content-relationships.excalidraw`
+
+### Example 3: Mind Map
+
+**User:** "Mind map about machine learning concepts"
+
+**Agent generates:**
+1. Center: "Machine Learning"
+2. Branches: Supervised Learning, Unsupervised Learning, Reinforcement Learning, Deep Learning
+3. Sub-topics under each branch
+4. Save as `machine-learning-mindmap.excalidraw`
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Elements overlap | Increase spacing between coordinates |
+| Text doesn't fit in boxes | Increase box width or reduce font size |
+| Too many elements | Break into multiple diagrams |
+| Unclear layout | Use grid layout (rows/columns) or radial layout (mind maps) |
+| Colors inconsistent | Define color palette upfront based on element types |
+
+## Advanced Techniques
+
+### Grid Layout (for Relationship Diagrams)
+```javascript
+const columns = Math.ceil(Math.sqrt(entityCount));
+const x = startX + (index % columns) * horizontalGap;
+const y = startY + Math.floor(index / columns) * verticalGap;
+```
+
+### Radial Layout (for Mind Maps)
+```javascript
+const angle = (2 * Math.PI * index) / branchCount;
+const x = centerX + radius * Math.cos(angle);
+const y = centerY + radius * Math.sin(angle);
+```
+
+### Auto-generated IDs
+Use timestamp + random string for unique IDs:
+```javascript
+const id = Date.now().toString(36) + Math.random().toString(36).substr(2);
+```
+
+## Output Format
+
+Always provide:
+1. ✅ Complete `.excalidraw` JSON file
+2. 📊 Summary of what was created
+3. 📝 Element count
+4. 💡 Instructions for opening/editing
+
+**Example summary:**
+```
+Created: user-workflow.excalidraw
+Type: Flowchart
+Elements: 7 rectangles, 6 arrows, 1 title text
+Total: 14 elements
+
+To view:
+1. Visit https://excalidraw.com
+2. Drag and drop user-workflow.excalidraw
+3. Or use File → Open in Excalidraw VS Code extension
+```
+
+## Validation Checklist
+
+Before delivering the diagram:
+- [ ] All elements have unique IDs
+- [ ] Coordinates prevent overlapping
+- [ ] Text is readable (font size 16+)
+- [ ] **All text elements use `fontFamily: 5` (Excalifont)**
+- [ ] Arrows connect logically
+- [ ] Colors follow consistent scheme
+- [ ] File is valid JSON
+- [ ] Element count is reasonable (<20 for clarity)
+
+## Icon Libraries (Optional Enhancement)
+
+For specialized diagrams (e.g., AWS/GCP/Azure architecture diagrams), you can use pre-made icon libraries from Excalidraw. This provides professional, standardized icons instead of basic shapes.
+
+### When User Requests Icons
+
+**If user asks for AWS/cloud architecture diagrams or mentions wanting to use specific icons:**
+
+1. **Check if library exists**: Look for `libraries/<library-name>/reference.md`
+2. **If library exists**: Proceed to use icons (see AI Assistant Workflow below)
+3. **If library does NOT exist**: Respond with setup instructions:
+
+   ```
+   To use [AWS/GCP/Azure/etc.] architecture icons, please follow these steps:
+   
+   1. Visit https://libraries.excalidraw.com/
+   2. Search for "[AWS Architecture Icons/etc.]" and download the .excalidrawlib file
+   3. Create directory: skills/excalidraw-diagram-generator/libraries/[icon-set-name]/
+   4. Place the downloaded file in that directory
+   5. Run the splitter script:
+      python skills/excalidraw-diagram-generator/scripts/split-excalidraw-library.py skills/excalidraw-diagram-generator/libraries/[icon-set-name]/
+   
+   This will split the library into individual icon files for efficient use.
+   After setup is complete, I can create your diagram using the actual AWS/cloud icons.
+   
+   Alternatively, I can create the diagram now using simple shapes (rectangles, ellipses) 
+   which you can later replace with icons manually in Excalidraw.
+   ```
+
+### User Setup Instructions (Detailed)
+
+**Step 1: Create Library Directory**
+```bash
+mkdir -p skills/excalidraw-diagram-generator/libraries/aws-architecture-icons
+```
+
+**Step 2: Download Library**
+- Visit: https://libraries.excalidraw.com/
+- Search for your desired icon set (e.g., "AWS Architecture Icons")
+- Click download to get the `.excalidrawlib` file
+- Example categories (availability varies; confirm on the site):
+   - Cloud service icons
+   - UI/Material icons
+   - Flowchart symbols
+
+**Step 3: Place Library File**
+- Rename the downloaded file to match the directory name (e.g., `aws-architecture-icons.excalidrawlib`)
+- Move it to the directory created in Step 1
+
+**Step 4: Run Splitter Script**
+```bash
+python skills/excalidraw-diagram-generator/scripts/split-excalidraw-library.py skills/excalidraw-diagram-generator/libraries/aws-architecture-icons/
+```
+
+**Step 5: Verify Setup**
+After running the script, verify the following structure exists:
+```
+skills/excalidraw-diagram-generator/libraries/aws-architecture-icons/
+  aws-architecture-icons.excalidrawlib  (original)
+  reference.md                          (generated - icon lookup table)
+  icons/                                (generated - individual icon files)
+    API-Gateway.json
+    CloudFront.json
+    EC2.json
+    Lambda.json
+    RDS.json
+    S3.json
+    ...
+```
+
+### AI Assistant Workflow
+
+**When icon libraries are available in `libraries/`:**
+
+**RECOMMENDED APPROACH: Use Python Scripts (Efficient & Reliable)**
+
+The repository includes Python scripts that handle icon integration automatically:
+
+1. **Create base diagram structure**:
+   - Create `.excalidraw` file with basic layout (title, boxes, regions)
+   - This establishes the canvas and overall structure
+
+2. **Add icons using Python script**:
+   ```bash
+   python skills/excalidraw-diagram-generator/scripts/add-icon-to-diagram.py \
+     <diagram-path> <icon-name> <x> <y> [--label "Text"] [--library-path PATH]
+   ```
+   - Edit via `.excalidraw.edit` is enabled by default to avoid overwrite issues; pass `--no-use-edit-suffix` to disable.
+   
+   **Examples**:
+   ```bash
+   # Add EC2 icon at position (400, 300) with label
+   python scripts/add-icon-to-diagram.py diagram.excalidraw EC2 400 300 --label "Web Server"
+   
+   # Add VPC icon at position (200, 150)
+   python scripts/add-icon-to-diagram.py diagram.excalidraw VPC 200 150
+   
+   # Add icon from different library
+   python scripts/add-icon-to-diagram.py diagram.excalidraw Compute-Engine 500 200 \
+     --library-path libraries/gcp-icons --label "API Server"
+   ```
+
+3. **Add connecting arrows**:
+   ```bash
+   python skills/excalidraw-diagram-generator/scripts/add-arrow.py \
+     <diagram-path> <from-x> <from-y> <to-x> <to-y> [--label "Text"] [--style solid|dashed|dotted] [--color HEX]
+   ```
+   - Edit via `.excalidraw.edit` is enabled by default to avoid overwrite issues; pass `--no-use-edit-suffix` to disable.
+   
+   **Examples**:
+   ```bash
+   # Simple arrow from (300, 250) to (500, 300)
+   python scripts/add-arrow.py diagram.excalidraw 300 250 500 300
+   
+   # Arrow with label
+   python scripts/add-arrow.py diagram.excalidraw 300 250 500 300 --label "HTTPS"
+   
+   # Dashed arrow with custom color
+   python scripts/add-arrow.py diagram.excalidraw 400 350 600 400 --style dashed --color "#7950f2"
+   ```
+
+4. **Workflow summary**:
+   ```bash
+   # Step 1: Create base diagram with title and structure
+   # (Create .excalidraw file with initial elements)
+   
+   # Step 2: Add icons with labels
+   python scripts/add-icon-to-diagram.py my-diagram.excalidraw "Internet-gateway" 200 150 --label "Internet Gateway"
+   python scripts/add-icon-to-diagram.py my-diagram.excalidraw VPC 250 250
+   python scripts/add-icon-to-diagram.py my-diagram.excalidraw ELB 350 300 --label "Load Balancer"
+   python scripts/add-icon-to-diagram.py my-diagram.excalidraw EC2 450 350 --label "EC2 Instance"
+   python scripts/add-icon-to-diagram.py my-diagram.excalidraw RDS 550 400 --label "Database"
+   
+   # Step 3: Add connecting arrows
+   python scripts/add-arrow.py my-diagram.excalidraw 250 200 300 250  # Internet → VPC
+   python scripts/add-arrow.py my-diagram.excalidraw 300 300 400 300  # VPC → ELB
+   python scripts/add-arrow.py my-diagram.excalidraw 400 330 500 350  # ELB → EC2
+   python scripts/add-arrow.py my-diagram.excalidraw 500 380 600 400  # EC2 → RDS
+   ```
+
+**Benefits of Python Script Approach**:
+- ✅ **No token consumption**: Icon JSON data (200-1000 lines each) never enters AI context
+- ✅ **Accurate transformations**: Coordinate calculations handled deterministically
+- ✅ **ID management**: Automatic UUID generation prevents conflicts
+- ✅ **Reliable**: No risk of coordinate miscalculation or ID collision
+- ✅ **Fast**: Direct file manipulation, no parsing overhead
+- ✅ **Reusable**: Works with any Excalidraw library you provide
+
+**ALTERNATIVE: Manual Icon Integration (Not Recommended)**
+
+Only use this if Python scripts are unavailable:
+
+1. **Check for libraries**: 
+   ```
+   List directory: skills/excalidraw-diagram-generator/libraries/
+   Look for subdirectories containing reference.md files
+   ```
+
+2. **Read reference.md**:
+   ```
+   Open: libraries/<library-name>/reference.md
+   This is lightweight (typically <300 lines) and lists all available icons
+   ```
+
+3. **Find relevant icons**:
+   ```
+   Search the reference.md table for icon names matching diagram needs
+   Example: For AWS diagram with EC2, S3, Lambda → Find "EC2", "S3", "Lambda" in table
+   ```
+
+4. **Load specific icon data** (WARNING: Large files):
+   ```
+   Read ONLY the needed icon files:
+   - libraries/aws-architecture-icons/icons/EC2.json (200-300 lines)
+   - libraries/aws-architecture-icons/icons/S3.json (200-300 lines)
+   - libraries/aws-architecture-icons/icons/Lambda.json (200-300 lines)
+   Note: Each icon file is 200-1000 lines - this consumes significant tokens
+   ```
+
+5. **Extract and transform elements**:
+   ```
+   Each icon JSON contains an "elements" array
+   Calculate bounding box (min_x, min_y, max_x, max_y)
+   Apply offset to all x/y coordinates
+   Generate new unique IDs for all elements
+   Update groupIds references
+   Copy transformed elements into your diagram
+   ```
+
+6. **Position icons and add connections**:
+   ```
+   Adjust x/y coordinates to position icons correctly in the diagram
+   Update IDs to ensure uniqueness across diagram
+   Add connecting arrows and labels as needed
+   ```
+
+**Manual Integration Challenges**:
+- ⚠️ High token consumption (200-1000 lines per icon × number of icons)
+- ⚠️ Complex coordinate transformation calculations
+- ⚠️ Risk of ID collision if not handled carefully
+- ⚠️ Time-consuming for diagrams with many icons
+
+### Example: Creating AWS Diagram with Icons
+
+**Request**: "Create an AWS architecture diagram with Internet Gateway, VPC, ELB, EC2, and RDS"
+
+**Recommended Workflow (using Python scripts)**:
+**Request**: "Create an AWS architecture diagram with Internet Gateway, VPC, ELB, EC2, and RDS"
+
+**Recommended Workflow (using Python scripts)**:
+
+```bash
+# Step 1: Create base diagram file with title
+# Create my-aws-diagram.excalidraw with basic structure (title, etc.)
+
+# Step 2: Check icon availability
+# Read: libraries/aws-architecture-icons/reference.md
+# Confirm icons exist: Internet-gateway, VPC, ELB, EC2, RDS
+
+# Step 3: Add icons with Python script
+python scripts/add-icon-to-diagram.py my-aws-diagram.excalidraw "Internet-gateway" 150 100 --label "Internet Gateway"
+python scripts/add-icon-to-diagram.py my-aws-diagram.excalidraw VPC 200 200
+python scripts/add-icon-to-diagram.py my-aws-diagram.excalidraw ELB 350 250 --label "Load Balancer"
+python scripts/add-icon-to-diagram.py my-aws-diagram.excalidraw EC2 500 300 --label "Web Server"
+python scripts/add-icon-to-diagram.py my-aws-diagram.excalidraw RDS 650 350 --label "Database"
+
+# Step 4: Add connecting arrows
+python scripts/add-arrow.py my-aws-diagram.excalidraw 200 150 250 200  # Internet → VPC
+python scripts/add-arrow.py my-aws-diagram.excalidraw 265 230 350 250  # VPC → ELB
+python scripts/add-arrow.py my-aws-diagram.excalidraw 415 280 500 300  # ELB → EC2
+python scripts/add-arrow.py my-aws-diagram.excalidraw 565 330 650 350 --label "SQL" --style dashed
+
+# Result: Complete diagram with professional AWS icons, labels, and connections
+```
+
+**Benefits**:
+- No manual coordinate calculation
+- No token consumption for icon data
+- Deterministic, reliable results
+- Easy to iterate and adjust positions
+
+**Alternative Workflow (manual, if scripts unavailable)**:
+1. Check: `libraries/aws-architecture-icons/reference.md` exists → Yes
+2. Read reference.md → Find entries for Internet-gateway, VPC, ELB, EC2, RDS
+3. Load:
+   - `icons/Internet-gateway.json` (298 lines)
+   - `icons/VPC.json` (550 lines)
+   - `icons/ELB.json` (363 lines)
+   - `icons/EC2.json` (231 lines) 
+   - `icons/RDS.json` (similar size)
+   **Total: ~2000+ lines of JSON to process**
+4. Extract elements from each JSON
+5. Calculate bounding boxes and offsets for each icon
+6. Transform all coordinates (x, y) for positioning
+7. Generate unique IDs for all elements
+8. Add arrows showing data flow
+9. Add text labels
+10. Generate final `.excalidraw` file
+
+**Challenges with manual approach**:
+- High token consumption (~2000-5000 lines)
+- Complex coordinate math
+- Risk of ID conflicts
+
+### Supported Icon Libraries (Examples — verify availability)
+
+- This workflow works with any valid `.excalidrawlib` file you provide.
+- Examples of library categories you may find on https://libraries.excalidraw.com/:
+   - Cloud service icons
+   - Kubernetes / infrastructure icons
+   - UI / Material icons
+   - Flowchart / diagram symbols
+   - Network diagram icons
+- Availability and naming can change; verify exact library names on the site before use.
+
+### Fallback: No Icons Available
+
+**If no icon libraries are set up:**
+- Create diagrams using basic shapes (rectangles, ellipses, arrows)
+- Use color coding and text labels to distinguish components
+- Inform user they can add icons later or set up libraries for future diagrams
+- The diagram will still be functional and clear, just less visually polished
