description	Transform text corpora (articles, docs, ideas, decisions) into Excalidraw-ready diagrams through a Socratic dialogue process. Analyzes content for visualizable concepts, engages in clarifying dialogue, then generates hybrid output (Mermaid for flowcharts, raw Excalidraw JSON for other diagram types). Designed for collaborative visual thinking and communication.

Text-to-Diagram Skill

Transform text into Excalidraw diagrams through structured Socratic dialogue.

Philosophy

This skill treats diagram generation as a collaborative sense-making process, not a one-shot transformation. The AI:

1. Studies the corpus to identify what's visualizable
2. Engages in Socratic dialogue to clarify your intent
3. Surfaces conceptual gaps or ambiguities
4. Only generates output after systematic completion

When to Use

• Articles/docs → Visual summaries or concept breakdowns
• Your ideas → Sketched-out thinking aids
• Difficult decisions → Decision trees, tradeoff matrices, comparison charts
• Meeting notes → Process flows, relationship maps
• Complex systems → Architecture diagrams, state machines

Workflow Phases

Phase 1: Analysis

AI reads the corpus and identifies:

• Visualizable concepts (processes, hierarchies, relationships, comparisons, timelines)
• Diagram type recommendations
• Entities, relationships, and flows

Output: Analysis summary + diagram candidates

Phase 2: Socratic Clarification

AI asks clarifying questions:

• "What's the primary audience for this diagram?"
• "Should X be shown as a process or a hierarchy?"
• "I see A and B as related — is that causal, temporal, or categorical?"
• "What level of detail do you want?"

Goal: Ensure the diagram serves your actual intent

Phase 3: Gap Filling

AI surfaces uncertainties:

• "The text doesn't specify whether X happens before or after Y"
• "There are three possible interpretations of this relationship"
• "This concept is mentioned but never defined — should we include it?"

Goal: Fill conceptual holes before rendering

Phase 4: Generation

Only after phases 1-3 are complete:

• Generate Mermaid code (for flowcharts — native Excalidraw rendering)
• Generate Excalidraw JSON (for other diagram types — full hand-drawn aesthetic)
• Provide import instructions

Invocation

Interactive Mode (Recommended)

Simply tell Zo:

"Run the text-to-diagram skill on this document"
"Diagram this article for me"
"Turn these meeting notes into a visual"

Zo will:

1. Read the corpus (file, pasted text, or URL)
2. Run analysis
3. Begin Socratic dialogue
4. Generate output after completion

Script Mode

For batch processing or automation:

python3 Skills/text-to-diagram/scripts/analyze.py --input <file> --output <dir>

Output Formats

Mermaid (.mmd)

Best for: Flowcharts only (native hand-drawn rendering in Excalidraw)

flowchart TD
  A[Input] --> B{Decision}
  B -->|Yes| C[Action 1]
  B -->|No| D[Action 2]

To use: Paste into Excalidraw's Mermaid tab

Excalidraw JSON (.excalidraw)

Best for: Everything else (mindmaps, ER diagrams, custom layouts, comparisons)

• Full control over positioning, styling, colors
• Native hand-drawn aesthetic for all shapes
• Direct import into Excalidraw

To use: File → Open in Excalidraw

Diagram Type Selection

Content Pattern	Diagram Type	Format
Steps, processes, workflows	Flowchart	Mermaid
Decisions with branches	Decision Tree	Mermaid
Cause → Effect chains	Causal Flow	Mermaid
Hierarchies, taxonomies	Tree / Mindmap	Excalidraw JSON
Entity relationships	ER-style	Excalidraw JSON
Comparisons, tradeoffs	Matrix / Quadrant	Excalidraw JSON
Timelines, sequences	Timeline	Excalidraw JSON
System components	Architecture	Excalidraw JSON
States and transitions	State Diagram	Excalidraw JSON

Aesthetic Defaults

All diagrams default to a neutral dark Excalidraw aesthetic. Adjust as needed for the project or brand:

• Background: #0f1115 (or transparent)
• Stroke: #f5f5f5 or muted grays
• Fill: Minimal, dark tones
• Font: Excalidraw hand-drawn (Virgil)
• Theme: Dark mode

Examples

Example 1: Article → Concept Map

Input: A long article about AI agents Analysis: "I found 4 key concepts: autonomy, tool use, memory, and planning. They form a hierarchy with 'agent' at the root." Socratic: "Should this emphasize the relationships between concepts, or the hierarchy?" Output: Excalidraw JSON mindmap

Example 2: Decision → Tradeoff Matrix

Input: "I'm deciding between staying at my job, starting a company, or joining a startup" Analysis: "This is a comparison of 3 options across multiple criteria" Socratic: "What criteria matter most? Risk tolerance? Financial upside? Learning?" Output: Excalidraw JSON quadrant chart or comparison matrix

Example 3: Process Doc → Flowchart

Input: A document describing an onboarding workflow Analysis: "I found a 7-step sequential process with 2 decision points" Socratic: "Should exceptions and error cases be shown, or just the happy path?" Output: Mermaid flowchart

Technical Notes

Mermaid Limitations in Excalidraw

Only flowcharts render natively. Other Mermaid types (sequence, class, ER, gantt) become rasterized images — defeating the hand-drawn aesthetic. That's why we use raw Excalidraw JSON for non-flowchart diagrams.

Excalidraw JSON Schema

Elements include: rectangle, ellipse, diamond, arrow, line, text, freedraw

Each element has:

• id, type, x, y, width, height
• strokeColor, fillColor, backgroundColor
• strokeWidth, roughness (0=smooth, 2=sketchy)
• For arrows: startBinding, endBinding (to connect shapes)
