mermaid-validator

What problem does it solve?

Mermaid diagrams embedded in docs can contain syntax errors that break rendering; this skill validates and can automatically fix common mistakes, preventing parse errors during documentation generation.

Core Features & Use Cases

• Syntax validation: Detects broken Mermaid syntax in architecture/design/sequence diagrams.
• Format checks: Validates C4 model usage and standard Mermaid constructs.
• Auto-corrections: Applies fixes for indentation, arrow notation, and node definitions.

Quick Start

Run the mermaid-validator skill on your docs to validate and automatically fix Mermaid diagrams (architecture.md/design.md/sequence.md and any Mermaid blocks in MD files).
