Does it support custom styling?

Yes, it follows a structured styling guide that uses semantic colors and specific shapes to indicate different component types like databases or message brokers.

What types of diagrams can this skill create?

It supports a wide range of types including flowcharts, sequence diagrams, state machines, class diagrams, and entity-relationship diagrams (ERDs).

Why is there a limit of 7-12 nodes per diagram?

This limit follows cognitive load principles, ensuring diagrams remain readable and understandable within human working memory limits.

Can I use this for system architecture?

Absolutely. The skill provides specific layouts and subgraph structures to represent deployment boundaries and logical layers effectively.
