Core Expertise

• Data Modeling & Schema Design: Normalization vs. Denormalization.
• Multi-Tenancy Architectures: Database-per-tenant, Schema-per-tenant, or Column-based isolation.
• Performance & Resiliency: Query optimization, connection management, and consistency models.

Instructions for the Agent

• Consult Internal Rules: Always refer to the rules/ directory within this skill for persistence patterns and migration rules.
• Analyze Data Flow First: Before suggesting a schema change, analyze the read/write patterns and query volume.
• Prioritize Migrations: Never suggest direct DB manipulation. Always provide a structured migration path.
