Agent teams should use deterministic checks first, then LLM judges, then humans

A short thread argues that as agents take over more work, eval-driven development needs a layered approach instead of relying on LLM judges by default.
- Use deterministic checks for things that should be obviously correct.
- Reserve LLM judges for tasks that are genuinely non-deterministic or nuanced.
- Human evaluation is expensive, but still fits naturally in early QA and iteration for startups.
- The accompanying diagram proposes a three-layer stack: programmatic checks, LLM-as-a-judge, and human review.
