# Query Performance Analyzer
## Overview
Analyze slow database queries using execution plans, wait statistics, and I/O metrics across PostgreSQL, MySQL, and MongoDB. This skill captures EXPLAIN output, identifies sequential scans on large tables, detects missing indexes, measures buffer cache hit ratios, and produces actionable optimization recommendations ranked by expected performance impact.
## Prerequisites
- Database credentials with permissions to run `EXPLAIN ANALYZE` (PostgreSQL), `EXPLAIN FORMAT=JSON` (MySQL), or `explain()` (MongoDB)
- `pg_stat_statements` extension enabled for PostgreSQL (provides aggregated query statistics)
- Access to slow query logs or performance_schema (MySQL)
- Baseline query execution times for comparison
- `psql`, `mysql`, or `mongosh` CLI tools installed
