I'm Willem van den Ende, partner at QWAN. This is where I write about agentic engineering, wishcraft, naive evals, and whatever prototype I'm building this week.
Every application has some kind of workflow. Understanding larger workflows, making them cohesive and understandable to users and developers is non-trivial. I re-discovered Ward Cunningham's Swim the Test approach, this is the Further Reading section of future posts.
I am making small contributions to tiny open source projects I have just started using, where I would let it be before coding agents.
Synthetic Test Driven Development is when you have a coding agent generate the tests and the code, and maybe also do the refactor step with an agent.
