MySQL Best Practices

Comprehensive coding standards for MySQL database development, optimized for AI agents and LLMs.

Overview

This skill provides 24 rules organized across 8 categories:

1. Query Optimization (query-) - EXPLAIN, N+1 prevention, pagination [CRITICAL]
2. Security (security-) - Prepared statements, least privilege, encryption [CRITICAL]
3. Schema Design (schema-) - Data types, normalization, constraints [HIGH]
4. Indexing Strategy (index-) - Composite indexes, covering indexes [HIGH]
5. Transaction Management (txn-) - ACID, isolation levels, deadlocks [MEDIUM-HIGH]
6. Connection Management (conn-) - Pooling, timeouts [MEDIUM]
7. Backup & Recovery (backup-) - Strategies, point-in-time recovery [MEDIUM]
8. Replication (repl-) - Master-slave, read replicas [LOW-MEDIUM]
