The post's thesis: LLMs are "brilliant but clumsy," so wrap that non-determinism in formal tooling. Ragel spits out a 10,000-line correct parser instantly; Claude, told in all caps never to parse by hand, does it anyway, and once committed a build/ directory twice.

The sharpest reply says he misnamed the problem: an LLM's trouble was never determinism. Its input is natural language, which was never formally defined, "words have meaning," and no parser generator can replace the layer that guesses what you meant.
