Domain-Specific AI Beats General AI on Niche Code. Here is Why.

If your AI coding assistant is great at React but keeps hallucinating on your Django ORM, or fine with Python but useless on your Rust lifetimes, or solid with webde but writes broken Godot scripts, this post is for you. The pattern is consistent across domains: general-purpose AI coding tools have a frontier they do well inside, and everything outside that frontier gets progressively worse. This post is about why, what to do about it, and when staying with a general tool is still the right call.
