SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Creating clear, shareable diagrams from ambiguous user requirements is time-consuming and error-prone. This skill automates diagram generation to reduce manual effort and ensure consistent syntax.

Core Features & Use Cases

  • Generate Mermaid diagrams of multiple types (flowchart, sequence, class, ER, Gantt, and more) directly from user requirements.
  • Save both raw Mermaid code (.mmd) and a Markdown preview with embedded diagram (.md) in a standardized figures/ directory.
  • Verify syntax automatically using Mermaid CLI and render a PNG for quick validation.
  • Enforce a strict quality review process and structured outputs to ensure publication-ready diagrams.
  • Typical use cases include documenting system architecture, workflow diagrams, and design specifications.

Quick Start

Provide a clear diagram request to the generator to produce the figures/ outputs immediately.

How do I verify Mermaid syntax and render a PNG for quick validation?▼

To verify Mermaid syntax and render a PNG for quick validation, the generation process applies Mermaid CLI. It automatically checks the syntax correctness and produces a PNG file alongside the diagram code outputs.

Does this diagram generation approach work for documenting system workflows and specifications?▼

Yes, this diagram generation approach works for documenting system workflows and specifications. It enforces a strict quality review process and structured outputs to ensure the generated diagrams are publication-ready for your design documentation.

Do I need to install Mermaid CLI to automate diagram generation and syntax checks?▼

You need Mermaid CLI installed to automate diagram generation and syntax checks effectively. The process relies on the CLI to verify the generated Mermaid syntax and render a PNG for quick visual validation of the outputs.

What is the best way to save Mermaid code and Markdown previews in a project?▼

The best way to save Mermaid code and Markdown previews in a project is using a standardized figures directory. The generation process automatically saves both the raw .mmd code files and the .md markdown previews in this specific location.
