database-optimizer

Quick Review

Excellent database optimization skill with comprehensive coverage of query analysis, indexing, and tuning workflows. The description clearly communicates when to invoke the skill (slow queries, execution plans, index design). Structure is exemplary with a clean reference guide linking to specialized docs for PostgreSQL, MySQL, monitoring, and query optimization details. The core workflow, constraints, and output templates provide strong operational guidance. Task knowledge is thorough, covering EXPLAIN analysis, index strategies, configuration tuning, and validation. Novelty is solid - database optimization requires specialized expertise in execution plans and database-specific tuning that would consume many tokens for a general CLI agent to replicate. Minor limitation: while highly competent, database optimization is a well-established domain, so novelty doesn't reach the highest tier reserved for truly unique or emerging capabilities.
