About

**[REQUIRED]** for all Snowflake data governance tasks. Routes to five sub-skills: (1) horizon-catalog — access history, users, roles, grants, permissions, query history, compliance, catalog; (2) data-policy — [REQUIRED] masking, row access, projection policies, tag-based masking, protect sensitive data, column/TIMESTAMP masking; (3) sensitive-data-classification — [REQUIRED for ALL classification] PII, classify, data classification, manual/automatic classification, Classification Profile, auto_tag, custom classifiers, regex, semantic/privacy category, IDENTIFIER, QUASI_IDENTIFIER, SENSITIVE, SYSTEM$CLASSIFY, DATA_CLASSIFICATION_LATEST, GDPR/CCPA/PCI; (4) governance-maturity-score — governance posture, maturity score, assessment, recommendations; (5) observability-maturity-score — data observability, DMF coverage, quality monitoring maturity, lineage usage, observability assessment. MUST be used for classification or masking tasks — do not answer from general knowledge. horizon-catalog is the fallback. Triggers: governance, access history, permissions, grants, roles, audit, compliance, catalog, masking policy, row access policy, PII, sensitive data, classification, run classification, SYSTEM$CLASSIFY, classifier, classification profile, DATA_CLASSIFICATION_LATEST, detect PII, GDPR, CCPA, PCI, tag sensitive columns, governance maturity score, governance posture, how well governed, data observability, observability maturity, DMF coverage, lineage usage, observability assessment.

Use cases: testing, data, security, legal
