description	Track Advanced Analytics model performance and inference volumes from ML monitoring tables — accuracy/drift metrics by model and version, plus serving request volumes. Ask me which models are degrading or which endpoints are busiest.

Overview

Surfaces Advanced Analytics ML operational health from model-monitoring metadata: it tracks per-model quality metrics (accuracy, drift) by version, and inference/serving request volumes over time. It reads aggregate monitoring metrics and request counts — not the scored records or their features — so it stays a Tier-2 (internal) skill.

When to use this skill

Reach for this skill when a data-science or MLOps user asks about model health:

• "Which models are degrading in accuracy over the last 30 days?"
• "Show me drift metrics by model version."
• "Which serving endpoints handled the most requests this week?"
• "Is the churn model's performance trending down?"

Instructions

When the user asks a model-health or inference-volume question:

1. Identify the model(s) and time window (default: last 30 days).
2. Query greenwood.analytics.model_metrics for quality metrics by model, version, and date.
3. Join greenwood.analytics.inference_logs for request volumes when throughput is asked.
4. Present results as a ranked table, then give 2–3 health observations (see the Recommendations framework).

Examples

Accuracy trend by model (last 30 days)

SELECT
  model_name,
  model_version,
  metric_date,
  metric_value AS accuracy
FROM greenwood.analytics.model_metrics
WHERE metric_name = 'accuracy'
  AND metric_date >= DATE_SUB(CURRENT_DATE(), 30)
ORDER BY model_name, metric_date

Busiest serving endpoints (last 7 days)

SELECT
  model_name,
  COUNT(*) AS request_count
FROM greenwood.analytics.inference_logs
WHERE request_date >= DATE_SUB(CURRENT_DATE(), 7)
GROUP BY model_name
ORDER BY request_count DESC

Recommendations framework

After presenting results, always include:

1. Biggest degradation — the model/version with the largest accuracy drop or highest drift, named.
2. Trend signal — which models are declining vs stable; flag any accuracy drop >5 points over the window.
3. Quick action — one MLOps observation (e.g. "drift on model X exceeds threshold — candidate for retraining").

Edge cases

• No metric rows — if a model has inference logs but no monitoring metrics, report it as unmonitored rather than implying healthy.
• Sparse windows — if the requested window has no rows, say so explicitly.
• Aggregate metrics only — this skill reads monitoring metrics and request counts, never the individual scored records or their input features.

Data scope

• greenwood.analytics.model_metrics — per-model, per-version quality metrics by date (aggregate)
• greenwood.analytics.inference_logs — serving request counts by model and date (aggregate)
• No PII or scored-record contents are accessed — only aggregate monitoring metrics.
