CIRCLE WITH A DOT

I've been having good results recently asking coding agents to provide "a linear walkthrough of the code that explains how it all works in detail" - I demonstrated that against this vibe coded Swift codebase and wrote up the technique here: https://simonwillison.net/guides/agentic-engineering-patterns/linear-walkthroughs/

@simon I have yet to find a model that makes good sounds. Bird chirps and whistles are excellent, but try a gunshot or an engine and you'll be disappointed.
