Can it visualize existing database schemas?

Yes, by analyzing your schema definitions or DDL files, the skill can generate clear visual representations of your existing database structure.

What diagram formats does this skill support?

The skill primarily focuses on Mermaid.js for seamless integration into Markdown and documentation, but can provide guidance for various visual documentation tools.

Does it work with NoSQL databases?

While optimized for relational schemas (SQL), it can be used to visualize document structures, collections, and data flows for NoSQL environments.

How do I activate this skill in Claude Code?

The skill activates automatically when you mention 'database schema visualizer' or ask Claude to create an ER diagram or visual model.

Do I need to install external software to see the diagrams?

The skill generates the code (like Mermaid) needed to render diagrams. These can be viewed in many code editors, GitHub, or online Mermaid live editors.
