Birgitta Böckeler adds exploration of three sensors for static code analysis, with mixed results. Computational sensors alone cannot help us much, AI is needed to add semantic interpretation, and consider trade-offs.

Birgitta Böckeler begins an article about her experiences with sensors in an agent harness. This first part looks at static analysis with basic code linting.

Fragments: thoughts from a software development retreat, would I be a writer without text editors, use LLMs as functions, don't use LLM skills, is the future of everything lies?

When I need to feed an LLM a lot of context, I can write it myself, or I can get an LLM to interview me for it.

Will there be source code in the future? To wrestle with this, we have to understand what code is. Unmesh Joshi sees code as having two distinct but intertwined purposes: instructions to a machine and a conceptual model of the problem domain.

@NateSilver538 It's certainly not vibecoding according to its original definition where you "forget that the code even exists". I like to follow @simonw's view here: https://t.co/4rvX9yp7NF

The term lost its precision quickly, but I think it's worth trying to restore it.

@shannah78 @WeiZhang595190 I've not had chance to do any more than scan your article. But I did notice you incorrectly attributed it to me. The authors are Wei Zhang (@WeiZhang595190) and Jessie Jie Xia. I am just the publisher.

Thoughtworks internal IT use a workflow for agentic programming called Structured-Prompt-Driven Development (SPDD). @WeiZhang595190 and Jessie Jie Xia describe how this works with a simple example plus details in a github project.
