mermaid skill

A Claude Code skill that analyzes source files, schemas, code, or a plain-text description and produces a Mermaid diagram — choosing the right diagram type automatically or using the one you specify.

features

• auto-detects the best diagram type from context: SQL files → ER, request flows → sequence, class hierarchies → class, logic/process → flowchart
• accepts a target: a file, directory, glob, or free-text description
• supports forced type with --type=<type> when you know what you want
• writes to a file with --output=<path>, or prints to the terminal if omitted
• validates syntax with the mermaid CLI before saving when npx is available
• always shows a preview and waits for confirmation before writing any file
