- Add sql-code-review.prompt.md: Universal SQL code review for security, maintainability, and quality standards
- Add sql-optimization.prompt.md: Universal SQL performance optimization for query tuning and indexing
- Add postgresql-code-review.prompt.md: PostgreSQL-specific code review focusing on PG best practices and anti-patterns
- Add postgresql-optimization.prompt.md: PostgreSQL-specific development assistant for unique PG features (JSONB, arrays, custom types)
This creates a complete 4-prompt ecosystem with zero overlap:
- Universal SQL (code quality + performance) for cross-database compatibility
- PostgreSQL-specific (code quality + performance) for PG-exclusive features
Each prompt serves distinct, isolated purposes while complementing each other for comprehensive SQL development support.
