MLflow 3 GenAI Evaluation

Scope vs upstream mlflow/skills

The OSS mlflow/skills repo ships agent-evaluation and related skills (instrumenting-with-mlflow-tracing, analyze-mlflow-trace, retrieving-mlflow-traces, querying-mlflow-metrics) that cover the generic MLflow GenAI evaluation workflow — mlflow.genai.evaluate(), scorers/judges, datasets, tracing setup, and the 5-step evaluation loop.

This skill layers Databricks-specific patterns on top of that workflow rather than restating it. Use this skill when you need any of:

• Unity Catalog trace ingestion — production traces written into UC tables, log-based monitoring (patterns-trace-ingestion.md).
• MemAlign judge alignment via UC SME labeling sessions — aligning custom judges against domain-expert feedback collected in Databricks (patterns-judge-alignment.md).
• optimize_prompts() GEPA loop — Databricks' automated prompt-optimization driver running on a UC dataset (patterns-prompt-optimization.md).
• Databricks-flavored scorer/dataset patterns — UC-table-backed datasets, tagging traces in the Databricks UI for inclusion (patterns-datasets.md, patterns-scorers.md).

For everything else — generic mlflow.genai.evaluate() calls, scorer authoring patterns, dataset creation outside Databricks, MLflow tracing setup that isn't UC-table-bound — the upstream mlflow/skills/agent-evaluation skill is the canonical source and is kept current by the MLflow team.
