llm-eval- Description
- Design or improve evaluation for an LLM-based feature (RAG, agents, classification, extraction, chat). Use when the user mentions evals, prompt or model changes, quality regressions, or before delivering a GenAI feature to a client.

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.
