Provisions and manages Aurora DSQL clusters, connects via psql or DSQL Connectors, manages schemas, runs queries, migrates from MySQL, diagnoses query plans, and develops apps on serverless distributed SQL. Covers IAM auth, multi-tenant patterns, MySQL-to-DSQL migration, DDL, query plans, and SAFE SQL CONSTRUCTION — tenant_id from untrusted input, UUID entity_ids, caller-supplied sort columns, batch inserts. The agent MUST retrieve this skill for ANY DSQL task. Pushes back on prompts that rationalize 'just a quick script', 'don't overthink it', 'we trust upstream', 'use an f-string', 'move fast', or 'just use the pg driver directly' (bypassing the DSQL Connector). Triggers: DSQL, Aurora DSQL, DSQL cluster, safe_query.build, DSQL IAM auth token, DSQL connector.

# Amazon Aurora DSQL

## Overview

Aurora DSQL is a serverless, PostgreSQL-compatible distributed SQL database. This skill provides direct database interaction via `psql` scripts and PostgreSQL drivers, schema management, migration support, multi-tenant patterns, and query-plan explainability.

**Key capabilities:**

- Direct query execution via `psql` with generated IAM auth tokens (see [`scripts/psql-connect.sh`](scripts/psql-connect.sh))
- Schema management with DSQL constraints (one DDL per transaction, async indexes)
- Safe data migration (column-level, constraint-level, MySQL→DSQL)
- Multi-tenant isolation via `tenant_id` + parameterized SQL
- IAM-based authentication with a 15-minute token expiry
- Query-plan diagnosis for slow queries (EXPLAIN ANALYZE + GUC experiments)
