Workflow 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

1. Visual Clarity — Each step is a distinct node with clear connections
2. FigJam/Miro Aesthetic — Colorful, rounded, friendly diagram style
3. Automated Export — Generate HTML → Screenshot → PNG ready to share
4. Smart Layout — Automatically arranges nodes in logical flow patterns
5. 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:

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.
