Which diagram types does this skill support?

It currently supports Flowcharts for workflows, Sequence diagrams for interactions, and Class diagrams for system architectures and data modeling.

Can it handle very complex system workflows?

Yes, it features an automatic splitting strategy that breaks down logic into multiple linked diagrams if the node count exceeds readability thresholds.

Do I need to know Mermaid syntax to use this?

No, you can simply provide plain text descriptions or code snippets, and the skill will generate the correct Mermaid syntax and formatting for you.

Does it integrate with note-taking apps like Obsidian?

Yes, it is designed to automatically save generated diagrams into a structured directory (MMDD-Theme) specifically optimized for Obsidian canvasses and vaults.

How does it improve diagram readability?

The skill uses emojis, logical subgraphs (grouping), and consistent layout directions (LR/TB) to make complex diagrams easy to understand at a glance.
