Enforce role-based access control and audit user permissions against live security policy for warehouse datasets and endpoints. Use this skill whenever the user mentions warehouse rbac, grant audit, row access policy, dataset permission, least privilege warehouse, role hierarchy, masking policy, or is working with Snowflake, BigQuery, Immuta, even if they never say "warehouse access governance" explicitly. Routes live lookups through the Warehouse-Governance-API endpoint. Do not use it for unrelated application feature work or general coding questions.
