An agentic skill for interactive C4 architecture diagrams

By Stephan in Feature on Sun 22 February 2026

We’ll be dealing with a lot more code in the near future. Using AI to help people understand existing systems seems more useful than generating even more of it. I built an agent skill that takes any folder of code and generates C4 diagrams and a local interactive HTML explorer for architecture review

Creating architecture diagrams with C4 and AI

By Stephan in Ai on Sat 18 January 2025

In this experiment I used AI to automate architecture documentation by testing Aider (an AI coding assistant). After just 5 minutes and 5 prompts, I generated a decent C4 diagram for a Streamlit web application. While not perfect, this experiment shows the promising future of AI-assisted documentation.
