Agent engineering: Agent SDK

In the previous post, I built a news reader that uses Claude Code as its execution environment. It worked well, but the project was spread across half a dozen config files, each in a different directory, connected by naming conventions. Changing anything meant knowing where each piece lived and how they were wired together.

That post ended with a teaser about the Claude Agent SDK and a five-line script that wraps the existing project. That was the lazy migration. This post goes the other direction: throw away the scaffolding and rebuild from scratch as a single Python file.
