Objective: no prompt, model, or retrieval change reaches the
client without numbers. Steps:

1. Define what "good" means for this feature with the user:
   observable criteria (factual accuracy, format, coverage,
   correct refusal, latency, cost). Without criteria there is no eval.
2. Build a versioned case dataset in the repo: typical cases,
   edge cases, adversarial cases, and cases that must be rejected.
   Start small (20-50) and grow with each real reported failure.
3. Choose the method by criterion: programmatic asserts where possible
   (format, fields, citations present), LLM-as-judge with written rubric
   where not, and sampled human review to calibrate the judge.
4. A single command runs the eval and returns score by criterion,
   compared against the previous run (detect regressions, not
   only the average).
5. Record every run: prompt version, model, parameters,
   dataset, and results. A change without a recorded run is not merged.

Rule: failures found in production or by the client become dataset cases
before they are fixed.

Rather not set it up yourself?

Chalk Labs scopes, builds and runs agents for your team: the task audit, the eval harness, the integrations and the weekly ops report. Fixed scope, priced before we start.
