Can I access diagrams created in previous Claude sessions?

Yes, this skill is specifically built for persistence, allowing you to list, search, and load diagrams across different sessions and projects.

Does this skill track changes made to my diagrams?

Every update creates a version snapshot automatically. You can include notes with your updates to explain what changed and why, then review the history later.

Can I organize diagrams by specific projects?

Yes, you can filter diagrams by scope (e.g., 'project:web-app') or use tags to categorize your diagrams for easier retrieval.

How do I find a diagram if I don't have the specific ID?

You can use the search tool to look for diagrams by keywords in their content or use the fuzzy title matching feature to find the right visual.

What formats can I export my diagrams to?

You can export diagrams as raw Mermaid files, SVG images via the Mermaid CLI, or in a format compatible with Draw.io.

Learning & Documentation

Manages and iterates on Mermaid diagrams across multiple sessions with full version history and multi-format export capabilities.

This skill empowers developers and architects to maintain visual documentation by loading, reviewing, and modifying persistent diagrams throughout a project's lifecycle. It eliminates the limitation of ephemeral charts by providing a searchable repository of Mermaid diagrams, complete with automatic version control that tracks content changes and explanatory notes. Users can seamlessly retrieve architecture flows from previous sessions, update them as the codebase evolves, and export the results into SVG, Draw.io, or Mermaid formats for team sharing, ensuring that system documentation remains accurate and accessible.
