Here Be Monsters: What Do You Still Need to Know When Agents Do the Work?

As AI agents like Codex increasingly handle software development tasks, developers must shift from writing code themselves to understanding systems well enough to identify and fix problems when they arise. The article illustrates this through an example where an AI agent produced working but overly complex code that failed code quality checks, requiring human intervention to refactor and pass CI/CD standards. This new paradigm demands developers develop "divebot" skills—knowing when something is wrong and being able to investigate deeply when needed—rather than relying on hands-on coding expertise.
