description	Automatically validate mermaid diagrams after creating or editing them in markdown files

When to Use This Skill

Proactively use this skill after:

• Creating new mermaid diagrams in markdown files
• Editing existing mermaid diagrams
• User asks to validate/check mermaid diagrams

Always validate before completing the task.

Instructions

1. Read the markdown file (use the file from context or ask user which file to validate)
2. Run validation using: mmdc -i <file-path> -o /tmp/mermaid-validation.svg 2>&1
3. Report validation results:
   • If valid: Confirm the diagram is valid and exit
   • If invalid: Show the errors found and explain what's wrong
4. Fix the issues automatically (invalid diagrams have no value)
5. Re-validate to confirm the fix worked
6. Repeat steps 4-5 until there are no validation issues
