Premature Compilation: Why agent developers write too much code
Most programmers building AI agents reach for frameworks before they understand the problem. The instinct to write code is the bottleneck. The primary artifact of agent development isn't code — it's natural language heuristics. Here's why, and what to do instead.

Here is what skills actually are, what they can't do, and the one test that separates signal from noise.
