skills/capabilities/create-workflow-diagram/SKILL.mdWorkflow Diagram Creator
Create FigJam/Miro-style workflow diagrams as PNG images. This skill takes a plain-text workflow description and generates a styled HTML diagram with connected nodes, directional arrows, and labels — then automatically screenshots it for sharing in docs, Slack, LinkedIn, or presentations.
Core Philosophy
- Visual Clarity — Each step is a distinct node with clear connections
- FigJam/Miro Aesthetic — Colorful, rounded, friendly diagram style
- Automated Export — Generate HTML → Screenshot → PNG ready to share
- Smart Layout — Automatically arranges nodes in logical flow patterns
- One-Command — Describe workflow in plain text, get a polished diagram
Output Specs
Format: PNG image
- Default size: 1920×1080px (landscape, presentation-friendly)
- Alternative sizes: 1080×1080px (square, LinkedIn), 1200×630px (blog/social)
- File format: PNG
- File size: Under 5MB
When to Use This Skill
Use for workflow/process diagrams like:
- "Find leads on Apollo → Enrich with Clay → Qualify with Claude → Send to Smartlead"
- "User signs up → Onboarding email → Trial → Upgrade prompt → Paid"
- "PR opened → CI runs → Review → Approve → Merge → Deploy"
- "Scrape data → Clean → Enrich → Score → Route to CRM"
NOT for:
- Org charts or hierarchy diagrams (use a tree layout tool)
- Complex flowcharts with many branches (use draw.io)
- Data architecture diagrams (use Mermaid or similar)
- Simple text lists (just use bullet points)
Workflow Overview
1. Content Input → User describes the workflow in plain text 2. Parse Steps → Extract nodes, connections, and labels 3. Style Selection → Choose visual style 4. HTML Generation → Create positioned diagram with SVG arrows 5. Screenshot → Auto-capture as PNG 6. Delivery → PNG file ready to share
Phase 1: Content Discovery
Step 1.1: Get Workflow Description
Ask the user:
Question 1: What's the workflow?
- Header: "Workflow"
- Question: "Describe the workflow steps. Use arrows (→) or numbers to show the flow."
- (Free text input)
- Examples:
- "1. Find leads on Apollo → 2. Enrich with Clay → 3. Qualify with Claude → 4. Send to Smartlead"
- "Scrape Reddit → Filter relevant posts → Draft comments → Send to Slack for review → Post"
Question 2: Layout Direction
- Header: "Layout"
- Question: "How should the diagram flow?"
- Options:
- "Left to Right" — Horizontal flow (default, best for 4-8 steps)
- "Top to Bottom" — Vertical flow (best for 3-5 steps)
- "Snake/Zigzag" — Wraps to next row (best for 6+ steps)
Question 3: Diagram Size
- Header: "Size"
- Question: "What size works best for your use case?"
- Options:
- "Landscape (1920×1080)" — Presentations, docs, Slack (default)
- "Square (1080×1080)" — LinkedIn, social media
- "Wide (1200×630)" — Blog headers, social cards
Step 1.2: Parse the Workflow
Extract structured data from the user's description:
Input: "1. Find leads on Apollo → 2. Enrich with Clay → 3. Qualify with Claude → 4. Send to Smartlead via API" Parsed: nodes: - id: 1, label: "Find leads", detail: "Apollo", icon: "🔍" - id: 2, label: "Enrich leads", detail: "Clay", icon: "✨" - id: 3, label: "Qualify leads", detail: "Claude", icon: "🤖" - id: 4, label: "Send to Smartlead", detail: "via API", icon: "📤" connections: - from: 1, to: 2 - from: 2, to: 3 - from: 3, to: 4
Parsing rules:
- Split on
,→
,->
, numbered lists, or line breaks> - Extract the primary action (label) and the tool/platform (detail)
- Auto-assign relevant emoji icons based on the action
- Detect branching if words like "if", "or", "else" appear
Icon assignment heuristics:
| Action keyword | Icon |
|---|---|
| find, search, discover | 🔍 |
| enrich, enhance, augment | ✨ |
| qualify, score, filter | 🎯 |
| send, email, outreach | 📤 |
| scrape, crawl, extract | 🕷️ |
| analyze, research | 📊 |
| review, approve | ✅ |
| deploy, ship, launch | 🚀 |
| store, save, database | 💾 |
| AI, Claude, GPT | 🤖 |
| alert, notify, Slack | 🔔 |
| clean, transform | 🧹 |
| merge, combine | 🔗 |
| schedule, automate | ⏰ |
Phase 2: Style Selection
Style Options
Question: Pick a Style
- Header: "Style"
- Question: "Which visual style?"
- Options:
- "FigJam Classic" — Colorful sticky-note nodes on dotted canvas (default)
- "Blueprint" — Technical dark theme with grid lines
- "Minimal White" — Clean white with thin borders and subtle shadows
- "Neon Flow" — Dark background with glowing neon connections
- "Pastel Board" — Soft pastel nodes on light background
See STYLE_PRESETS.md for full details on each style.
Phase 3: Generate HTML Diagram
File Structure
skills/create-workflow-diagram/[diagram-name]/ ├── diagram.html # Full diagram page └── exports/ └── diagram.png # Screenshot (generated in Phase 4)
HTML Architecture
The diagram is built with pure HTML/CSS using absolute positioning for nodes and SVG for arrows.
CRITICAL: Use absolute positioning for precise node placement. Use SVG overlay for arrows/connections.

Layout Algorithms
Left-to-Right (default for 4-8 steps):
Position each node evenly across the width: - totalWidth = diagramWidth - (2 * margin) - nodeSpacing = totalWidth / (nodeCount - 1) - node[i].x = margin + (i * nodeSpacing) - (nodeWidth / 2) - node[i].y = (diagramHeight / 2) - (nodeHeight / 2) For the default 1920×1080 with 4 nodes: - margin = 200px - spacing = ~507px - y = ~460px (vertically centered)
Top-to-Bottom (3-5 steps):
- totalHeight = diagramHeight - (2 * margin) - nodeSpacing = totalHeight / (nodeCount - 1) - node[i].y = margin + (i * nodeSpacing) - (nodeHeight / 2) - node[i].x = (diagramWidth / 2) - (nodeWidth / 2)
Snake/Zigzag (6+ steps):
- maxPerRow = 4 - rowHeight = 250px - For each row, alternate left-to-right and right-to-left - Row 0: nodes flow → - Row 1: nodes flow ← - Row 2: nodes flow → - Connect last node of row to first node of next row with vertical arrow
Arrow Drawing
Arrows are drawn as SVG lines between node edges:
// Calculate arrow coordinates between two nodes function getArrowCoords(fromNode, toNode, direction) { if (direction === 'horizontal') { // Arrow from right edge of fromNode to left edge of toNode const x1 = fromNode.x + fromNode.width; const y1 = fromNode.y + fromNode.height / 2; const x2 = toNode.x; const y2 = toNode.y + toNode.height / 2; return { x1, y1, x2, y2 }; } if (direction === 'vertical') { // Arrow from bottom of fromNode to top of toNode const x1 = fromNode.x + fromNode.width / 2; const y1 = fromNode.y + fromNode.height; const x2 = toNode.x + toNode.width / 2; const y2 = toNode.y; return { x1, y1, x2, y2 }; } }
For curved arrows (more FigJam-like), use SVG
<path> with cubic bezier:
<path d="M 380,490 C 430,490 470,490 520,490" stroke="var(--arrow-color)" stroke-width="3" fill="none" stroke-dasharray="8,6" marker-end="url(#arrowhead)" />
For snake layout vertical connectors between rows:
<!-- Vertical connector from end of row 1 to start of row 2 --> <path d="M 1500,550 C 1500,620 200,620 200,690" stroke="var(--arrow-color)" stroke-width="3" fill="none" stroke-dasharray="8,6" marker-end="url(#arrowhead)" />
Branching (Optional)
If the workflow has conditional branches:
Step 3: Qualify leads ├── Yes → Step 4a: Send to Smartlead └── No → Step 4b: Add to nurture sequence
Render as:
- Main node for step 3
- Two arrows diverging from step 3
- Label on each arrow ("Qualified" / "Not Qualified")
- Two destination nodes
<!-- Branch label on arrow --> <text x="650" y="400" font-size="14" fill="var(--text-secondary)" font-family="Inter" font-weight="600">Qualified</text>
Phase 4: Screenshot Generation
After generating HTML, automatically capture a screenshot.
Using Playwright
cd /path/to/skills/create-workflow-diagram node screenshot-diagram.js <diagram-name>
This will:
- Open the diagram HTML in a headless browser
- Set viewport to the diagram dimensions (e.g., 1920×1080)
- Wait for fonts to load
- Capture PNG screenshot at 2x resolution
- Save to the diagram's
directoryexports/
Installation
First time setup:
cd /path/to/skills/create-workflow-diagram npm install
Phase 5: Delivery
After the screenshot is generated, present to user:
Your workflow diagram is ready! HTML source: skills/create-workflow-diagram/[name]/diagram.html PNG export: skills/create-workflow-diagram/[name]/exports/diagram.png Preview: Open diagram.html in a browser to see the full diagram. Diagram details: - 4 workflow steps connected with arrows - Style: FigJam Classic - Size: 1920×1080px (landscape) - File size: ~350 KB Want to make any changes?
Node Sizing Rules
Keep nodes consistent and readable:
| Element | Size |
|---|---|
| Node width | 200-240px |
| Node min-height | 110-140px |
| Node padding | 20-28px |
| Icon | 32-40px |
| Label font | 20-24px, weight 700 |
| Detail font | 14-16px, weight 500 |
| Step badge | 28-34px circle |
| Arrow stroke | 2-3px |
| Arrow gap | 60-100px between nodes |
Content Rules
Each node should have:
- Step number — Badge in top-left corner
- Icon — Relevant emoji (auto-assigned from keyword)
- Label — Action in 2-4 words (e.g., "Find Leads")
- Detail — Tool/platform name (e.g., "Apollo") — optional
If a label is too long, truncate or split across lines. Max 2 lines for label.
Troubleshooting
Nodes Overlap
Solution: Increase
--node-gap or switch to snake layout for many nodes.
Arrows Misaligned
Solution: Recalculate arrow start/end points based on actual node positions. Use the center of the node edge closest to the target.
Fonts Not Loading
Solution: Add
await page.waitForLoadState('networkidle') before screenshot. Increase timeout to 1000ms.
Diagram Too Crowded
Solution: Reduce node count by combining steps, switch to a larger canvas size, or use snake layout.
