database-optimizer

Quick Review

Excellent database optimization skill with comprehensive coverage of real-world tuning scenarios. The description is highly actionable, clearly stating when to invoke (slow queries, execution plans, index design, etc.). Structure is exemplary: concise SKILL.md overview with organized reference files for detailed guidance. The core workflow, constraints (MUST/MUST NOT), and output templates provide strong task knowledge for both PostgreSQL and MySQL. Reference table elegantly directs agents to load context-specific details. Novelty is solid—database optimization requires deep domain expertise in execution plans, index strategies, and configuration tuning that would be token-intensive for a general CLI agent to derive. Minor consideration: while highly useful, some aspects (like basic EXPLAIN analysis) might be achievable by advanced agents, slightly limiting novelty score. Overall, this is a well-architected skill that meaningfully reduces token cost and improves outcomes for database performance tasks.
