This is the final part of a 5-part series on agentic engineering. Part 4 laid out architectural principles for choosing languages and runtimes. This post puts a handful of worked examples through those principles, just to show what the analysis looks like in practice.

This isn’t a list of “the languages I use”, and it isn’t exhaustive. It’s a deliberate move away from personal taste — what I happen to know, what’s fashionable, what the team is already comfortable with — and toward something more objective: which language properties best fit the agent and the problem domain in front of you. Different problems will pull you toward different answers, and the examples below are picked specifically to make that point.
