## AI overview

The article argues that AI coding agents depend heavily on the feedback available during their work loop. Compile-time type errors are especially useful because they are fast, deterministic, and localized, while many backend mistakes appear later or produce no signal the agent can act on.

## Source excerpt

An agent only fixes what it can see before it stops, and a compile error is the one signal that always lands in time.
