The SQL Query skill takes “what’s our 30-day MRR retention by acquisition channel?” and produces a parameterized SQL query against your schema. Reads schema either from a Supabase / Postgres URL or from a schema.sql file in the workspace.

Safety: never auto-executes. Always returns the query for human review first.

Best for: founders who own data but don’t write SQL daily.

Pairs well with: Supabase MCP for execution after review.
