Simon Willison highlights case study on agentic engineering

Simon Willison links to a case study on agentic engineering, calling it fascinating and saying it raised his eyebrows at least a dozen times.

The case study is an article by @jsnnsa, and Willison's post does not describe its contents in detail.

The post refers to the "Fable era" and to what it calls the sharpest edge of agentic engineering, but gives no further specifics about the cases or findings.
