Your architecture diagrams have unlabeled arrows, mystery boxes & 12 different shades of blue. Nobody knows what any of it means. @simonbrown wrote the book that helps & Susanne Kaiser asked him everything you need to know about it. GOTO Book Club 👇 youtu.be/sfqHggWY5Ds?li…

Still relying on confusing architecture diagrams? 🏗️ Attend @simonbrown's hands-on workshop to learn why most diagrams fail, how to fix them, and how the C4 model can help you create clearer views of your software systems. 🔗 dev2next.com/schedule 🎟️ dev2next.com

Every C4 tool I've used makes you trade something: a nice canvas, or a file you can commit. Pretty UI, or git history. SaaS lock-in, or no visual editor at all. I got tired of the tradeoff and built one that doesn't ask. Free, open source, live now 🧵

I've shifted most of my time r/w code to r/w systems diagrams. We need the equivalent of a "modern programming language" for diagrams. What we currently have feels like Fortran.
Johannes Schickling@schickling

System diagrams are one of the most important foundations for the agentic software engineering. Yet the current generation of tooling (e.g. Mermaid) feel incredibly antiquated (e.g. getting the layout right in a declarative way is close to impossible). Are there some new tools?

Take it further with something like Structurizr and C4 — architecture as code. Now your AI isn't just generating features, it's a participant in the architectural conversation.

AI-generated architecture diagrams: pretty but possibly wrong. Must be validated against actual implementation. Evidence includes both the AI output and the human sign-off. #ProofDrivenDeliveries #CompliantDeliveries

I’ve been having some fun asking Claude to review architecture diagrams during my software architecture workshop today. 😂

@HumanTechGuy I think 3/10 is in the right ballpark for this particular diagram. The humans rated it a 6/10. 😀

@simonbrown Three out of ten is generous for a diagram that blends container and component levels without declaring its type. Claude is an optimist.
