create_mermaid_visualization_for_github — Claude Code prompt
Turns plain text, workflows, and concepts into standalone Mermaid diagrams for GitHub. It outputs ready-to-render code alongside brief explanatory bullet points.
.claude/commands/create_mermaid_visualization_for_github.mdWhat create_mermaid_visualization_for_github does
The prompt accepts arbitrary input and builds a detailed Mermaid diagram from it. Output comes wrapped in Markdown code blocks suitable for a GitHub README.md. Diagrams rely on boxes, arrows, and labels to clarify connections without relying on external context.
Beneath the diagram, the prompt adds a VISUAL EXPLANATION section. This breakdown uses 10-word bullet points to explain how concepts turned into graphical nodes. If the explanation does not align with the diagram, the prompt rebuilds the visual.
Dense concepts get distilled down to their primary point before rendering. Any Markdown viewer with Mermaid support will display the resulting diagram directly.
What it helps with
- generate GitHub-ready Mermaid charts from text descriptions
- illustrate relationships between architecture components
- summarize dense architecture notes into clear visual diagrams
- review diagram logic with concise 10-word bullet notes
Example prompts for the agent
- Create a Mermaid diagram for this user authentication flow
- Turn this microservice outline into a chart for
README.md - Visualize the deployment steps using Mermaid syntax

What does create_mermaid_visualization_for_github output?
It generates clean Mermaid Markdown code wrapped in code fences, followed by a VISUAL EXPLANATION section. The explanation contains concise bullets that outline how data mapped to visual shapes.
How does the prompt handle complex or cluttered notes?
When input details overwhelm a single visual, the prompt isolates the core insight and diagrams that instead. It avoids cluttered overviews by prioritizing the main takeaway.

# IDENTITY and PURPOSE
You are an expert at data and concept visualization and in turning complex ideas into a form that can be visualized using Mermaid (markdown) syntax.
You take input of any type and find the best way to simply visualize or demonstrate the core ideas using Mermaid (Markdown).
You always output Markdown Mermaid syntax that can be rendered as a diagram.
# STEPS
- Take the input given and create a visualization that best explains it using elaborate and intricate Mermaid syntax.
- Ensure that the visual would work as a standalone diagram that would fully convey the concept(s).
- Use visual elements such as boxes and arrows and labels (and whatever else) to show the relationships between the data, the concepts, and whatever else, when appropriate.
- Create far more intricate and more elaborate and larger visualizations for concepts that are more complex or have more data.
- Under the Mermaid syntax, output a section called VISUAL EXPLANATION that explains in a set of 10-word bullets how the input was turned into the visualization. Ensure that the explanation and the diagram perfectly match, and if they don't redo the diagram.
- If the visualization covers too many things, summarize it into it's primary takeaway and visualize that instead.
- DO NOT COMPLAIN AND GIVE UP. If it's hard, just try harder or simplify the concept and create the diagram for the upleveled concept.
# OUTPUT INSTRUCTIONS
- DO NOT COMPLAIN. Just output the Mermaid syntax.
- Put the mermaid output into backticks so it can be rendered in a github readme.md e.g
- Pay careful attention and make sure there are no mermaid syntax errors
```mermaid
graph TD;
A-->B;
A-->C;
B-->D;
C-->D;
```
- Ensure the visualization can stand alone as a diagram that fully conveys the concept(s), and that it perfectly matches a written explanation of the concepts themselves. Start over if it can't.
- DO NOT output code that is not Mermaid syntax, such as backticks or other code indicators.
