SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps users create professional Mermaid diagrams (sequence, architecture, flowcharts) and ensures they render correctly by automatically validating with mermaid-cli and applying self-healing fixes if issues are detected.

Core Features & Use Cases

Diagram Types: Sequence diagrams, Architecture diagrams, and Flowcharts using Mermaid syntax
Automatic Validation: Runs mermaid-cli validation to ensure syntax correctness and valid SVG output
Self-Healing: Automatically applies fixes for common syntax issues and re-validates
Use Case: Visualize an API flow or system architecture with a validated diagram ready for documentation

Quick Start

Use this skill to generate a simple sequence diagram for a login flow, automatically validate it, and deliver a ready-to-render diagram.

FAQPage Schema

How do I validate Mermaid diagrams automatically?▼

Validate Mermaid diagrams by running mermaid-cli syntax checks that confirm rendering correctness. This Skill automates validation, detects errors, applies self-healing fixes for common syntax issues, and re-validates until the diagram renders correctly.

Can I generate sequence diagrams and flowcharts with automatic error correction?▼

Yes. Generate sequence diagrams, architecture diagrams, and flowcharts with built-in mermaid-cli validation and self-healing fixes. The Skill automatically corrects syntax errors and delivers only validated, render-ready diagrams.

What diagram types can I create with Mermaid validation?▼

Mermaid supports sequence diagrams for API flows, architecture diagrams for system design, and flowcharts for process documentation. This Skill validates all three types using mermaid-cli to ensure syntax correctness and SVG output quality.

Do I need mermaid-cli installed to use validated diagram generation?▼

Yes. Mermaid-cli is required as the validation engine. The Skill also requires bash access and /tmp directory permissions to validate diagrams, apply self-healing fixes, and output validated results.

How does self-healing fix diagram validation errors?▼

Self-healing detects mermaid-cli validation failures, identifies common syntax issues, applies corrections automatically, and re-validates the diagram. This iterative process ensures diagrams render without manual troubleshooting.

What's the best way to document system architecture with diagram validation?▼

Use architecture diagram generation with automatic mermaid-cli validation to visualize system components and flows. Self-healing fixes ensure syntax correctness, delivering professional diagrams ready for documentation without manual validation cycles.
