Dev realizes his 2023 tool already draws AI tool-calling as sequence diagrams
dfinke · x · 2026-09-28
Developer dfinke shares that when someone suggested "draw AI inference as a sequence diagram," he initially had no idea what that meant — until he realized he had already built such a visualization tool in 2023, back when OpenAI released function/tool calling. The linked demo shows model-tool interactions rendered as a sequence diagram, a handy way to understand multi-step agent call chains.
