Week 5 · Lesson 16
Evals suite
Grade quality and policy. Pair with Evals & observability. Re-run when you change models.
Learn
- Golden sets, schema checks, trajectory/policy checks
- LLM-as-judge vs human labels (when each fits)
- Regression discipline on prompt/model swaps
Build
evals/with 10–20 fixtures (topics + expectations)- Runner: schema + “never publish without approve”
- Optional rubric judge for hook quality
- Script:
pnpm evalagainst LM Studio
Checkpoint
Change model → eval report shows pass/fail deltas. Failures are explainable via run traces.
Four notes
- What problem does this layer solve?
- What is allowed to call it?
- What must it never do?
- How do I observe and test it?
