Agent engineering: Agent SDK

The author rebuilds a news reader project using the Claude Agent SDK, consolidating a scattered multi-file setup into a single Python script to simplify configuration and maintenance.

In the previous post https://roman.pt/posts/claude-code-as-your-execution-environment/ , 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 https://code.claude.com/docs/en/agent-sdk/overview 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.
