What level of technical detail does it provide?

It follows a 'depth over breadth' principle, providing implementation details, algorithm explanations, dependency rationale, and engineering analysis of failure modes.

What types of diagrams can this skill generate?

It supports PlantUML (via Kroki), Mermaid, and Eraser, allowing for C4 model diagrams, sequence diagrams, and cloud infrastructure visualizations with professional icons.

Does it document API endpoints?

Yes, it includes an optional appendix for API endpoint references, documenting methods, paths, authentication requirements, and request/response schemas.

Does it handle complex multi-service architectures?

Yes, it is specifically designed to identify services, modules, and databases, mapping their dependencies and tracing data flows across the entire system.

Can I use this to update existing documentation?

Absolutely. The skill can analyze existing docs, identify what has changed in the code, and update only the relevant sections to maintain accuracy.

Learning & Documentation

Generates high-rigor technical architecture documentation and system diagrams directly from your codebase.

This skill transforms complex codebases into comprehensive, engineer-focused architecture documentation, providing deep insights into system design, data flows, and component interactions. It moves beyond high-level summaries by producing formal abstracts, component responsibility matrices, and detailed engineering analyses of trade-offs and failure modes. By leveraging industry-standard diagramming tools like PlantUML, Mermaid, and Eraser, it visualizes system structure and request lifecycles, making it an essential tool for technical handoffs, system audits, and onboarding new developers.
