Evals
This site's chatbot grades itself every night.
A fixed set of 16 test prompts runs against the live chat's system prompt in CI. An LLM judge scores every answer for groundedness, scope control, persona integrity, and prompt-injection resistance. The scores land here, unedited. I say evals are the part of AI engineering that matters; this page is me acting like it.
