SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires trailmark, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the challenge of visualizing complex code architecture, making it easier to understand and maintain.

Core Features & Use Cases

  • Code Visualization: Generates Mermaid diagrams from code graphs, including call graphs, class hierarchies, module dependency maps, and more.
  • Code Analysis: Provides insights into code complexity, data flow, and attack surface.
  • Use Case: Visualize the structure of a large codebase to identify potential issues like code duplication, performance bottlenecks, or security vulnerabilities.

Quick Start

Generate a call graph for the 'src' directory using the diagramming-code skill:

uv run {baseDir}/scripts/diagram.py --target src --type call-graph

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate Mermaid diagrams from code to visualize architecture?▼

To generate Mermaid diagrams from code, run the diagramming script targeting a directory like 'src' with a specific type, such as call-graph. This produces visual representations of code structure and dependencies.

What is code visualization used for during code review and debugging?▼

Code visualization generates call graphs, class hierarchies, and module dependency maps to identify structural issues. It helps spot code duplication, performance bottlenecks, and security vulnerabilities during review.

Do I need trailmark to perform code graph analysis and dependency mapping?▼

Yes, you need trailmark to perform code graph analysis. The diagramming process requires trailmark to parse the code structure and map dependencies before generating the visual Mermaid diagrams.

Can I analyze code complexity and data flow for a large codebase?▼

Yes, you can analyze code complexity and data flow for large codebases. The skill generates module dependency maps and call graphs, providing visual insights into the overall architecture and attack surface.

What types of diagrams can I create for code structure analysis?▼

You can create multiple diagram types for code structure analysis, including call graphs, class hierarchies, and module dependency maps. These are generated as Mermaid diagrams from the underlying code graphs.
