About
The Databases skill provides a comprehensive toolkit for handling both document-oriented (MongoDB) and relational (PostgreSQL) data systems within Claude Code. It assists developers in selecting the appropriate database architecture, writing optimized SQL or MQL queries, building sophisticated aggregation pipelines, and managing production-level tasks like migrations, backups, and sharding. Whether you are building a rapid prototype with flexible schemas or a strictly consistent financial system, this skill offers the domain-specific guidance and best practices needed to maintain high-performance, scalable data layers.
