Evaluation harness & guardrails

The test suite for a probabilistic system, covering correctness, safety, regression and drift.

4–8 weeksTypical duration

The problem this solves

You cannot change the prompt, the model or the retrieval without a quiet fear that something else got worse.

What you receive

Artefacts you can hold, and that you can accept or refuse — never a list of activities.

  • An evaluation set built from your real traffic, with the grading criteria written down
  • An automated evaluation run on every change, reporting per-category deltas
  • Guardrails for the failure modes that actually matter to you, tested rather than assumed
  • A regression gate, so a change that degrades a category cannot ship silently
