AI summary
Auto-generated overview of what this skill does and when to reach for it.
Turns plain YAML business rules into optimized SQL for BigQuery, Snowflake, PostgreSQL and others so AI agents and tools query data using business terms instead of raw schemas.
Use this when
- AI agents need governed access to your data warehouse
- you want to query using business terms like 'Customer Lifetime Value' instead of table/column names
- you need consistent metrics across different SQL dialects
- you're migrating BI tools but want to keep existing reports and KPIs
- you want to enforce data quality rules as part of query execution
Don't use when
- you need real-time transactional queries with sub-second latency
- your data lives only in NoSQL or non-SQL stores like MongoDB or Kafka
Capabilities
- compiles YAML business semantics into dialect-specific SQL
- supports BigQuery, Snowflake, PostgreSQL, ClickHouse, Databricks, Dremio, DuckDB, MySQL
- enforces business rules and data quality checks at query time
- provides REST and SQL wire protocols (PostgreSQL, Flight SQL)
- exposes metrics, dimensions, and hierarchies via a unified API
- integrates with AI agents via MCP for governed text-to-SQL
