Dsql

This gives Claude direct access to Aurora DSQL through MCP tools, so it can execute queries, manage schemas, and handle migrations without writing throwaway scripts. The skill knows DSQL's quirks: no foreign keys (you handle integrity in app code), 3,000 row transaction limits, and table recreation patterns for column drops. It covers IAM auth setup, multi-tenant isolation, and includes a MySQL migration path with type mappings. The query plan explainability workflow is unusually thorough, walking through EXPLAIN ANALYZE output with catalog queries and GUC experiments. Useful if you're building on a distributed SQL database that behaves like Postgres but has its own constraints.
