Cr Data Layer — Data & AI agent for Claude Code

name: cr-data-layer description: Data-layer lens — measured query cost, schema migrations and bulk data writes. Spawn when the diff adds or changes a query (raw SQL, ORM relation, scope, query object, a report that builds a query), touches a migration or schema dump, or writes data in bulk while bypassing the model layer. Do NOT spawn when the query change is only a rename or a column reordering that cannot change the execution plan. model: inherit tools: Read, Grep, Glob, Bash
