SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill solves the problem of unclear technical Markdown documentation that requires visual diagrams to explain architecture, workflows, state transitions, and data relationships, eliminating the guesswork of selecting the correct Mermaid diagram type and structure for each use case.

Core Features & Use Cases

  • Intelligent Diagram Type Matching: Automatically maps your documentation question to the appropriate Mermaid diagram type (e.g., flowcharts for dependency mapping, sequence diagrams for interaction flows, state diagrams for state transitions) to maximize clarity.
  • Approval-Gated Generation Workflow: Guides you through a structured 7-step process to plan diagram inventory, get explicit user approval before writing any files, and generate consistent, well-formatted diagram Markdown files to avoid wasted work.
  • Built-in Reference Support: Includes ready-to-use references for Mermaid CLI flags, common quirks, and real-world walkthroughs of simple, complex, and trivial diagramming scenarios to speed up implementation.
  • Use Case: When documenting a new checkout service, use this Skill to generate an aligned set of diagrams including an overview layer boundary diagram, payment state diagram, and API interaction sequence diagram, all approved by your team before being written to disk.

Quick Start

Use the documenting-with-diagrams skill to generate a set of approved Mermaid diagrams for the user authentication module, including an overview layer boundary diagram and a login sequence diagram, saved to the module's diagrams directory.

FAQPage Schema
How do I add Mermaid diagrams to Markdown documentation?▼

To add Mermaid diagrams to Markdown documentation, you can use a guided workflow that selects the appropriate diagram type and generates structured syntax. This maps your software architecture or workflow requirements to proper Mermaid formats, preventing manual guesswork and syntax errors.

Which Mermaid diagram type should I use for software architecture?▼

For software architecture, flowcharts map dependencies, sequence diagrams handle interaction flows, and state diagrams track state transitions. Selecting the correct Mermaid diagram type maximizes clarity by matching the specific structural relationship you need to visualize.

What is the best way to generate sequence diagrams for technical docs?▼

The best way to generate sequence diagrams for technical docs is through an approval-gated workflow that plans the diagram inventory and confirms the structure before writing files. This ensures consistent, well-formatted Markdown that aligns with diagramming best practices.

Can I pre-render Mermaid diagrams to SVG output?▼

Yes, you can pre-render Mermaid diagrams to SVG output format using Mermaid CLI integration. This allows you to embed pre-rendered SVG files directly into your Markdown documentation alongside standard inline Mermaid code blocks.

Why do my Mermaid diagrams have syntax errors in Markdown?▼

Mermaid diagrams often have syntax errors in Markdown due to structural inconsistencies and common quirks. Preventing these errors requires using built-in references for Mermaid CLI flags and applying standard diagramming best practices during generation.
