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.
