Does this skill work in all terminals?

Yes, it uses standard UTF-8 box-drawing characters and limits output width to 80 characters for maximum terminal and markdown compatibility.

What types of diagrams can it generate?

It is optimized for architecture overviews, before/after comparisons, phased migration steps, data flow pipelines, and relationship/synergy maps.

How does staleness detection work?

The skill embeds metadata in your diagrams that tracks source file patterns and creation dates, allowing Claude to flag when a diagram might be outdated due to recent code changes.

Can I convert these diagrams to high-quality images?

While the primary output is text-based, the skill includes a Mermaid export feature that converts ASCII diagrams into Mermaid syntax for graphical rendering in tools like GitHub or Notion.

Learning & Documentation

Generates terminal-compatible ASCII diagrams to visualize system architecture, data flows, and migration phases directly within your CLI.

About

This skill empowers developers to create clear, professional visual representations of their codebase and workflows using standard box-drawing characters. It goes beyond simple text by offering codebase auto-discovery, project-specific templates, and Git-aware staleness detection to ensure diagrams remain accurate as the code evolves. By providing export options to Mermaid and integration with pull request templates, it bridges the gap between terminal-based planning and high-level documentation, making it an essential tool for technical communication and architectural reviews.
