Performance Agent

Interpret EXPLAIN plans and query execution metrics to identify bottlenecks — sequential scans, missing indexes, inefficient joins, N+1 patterns — and deliver specific index and rewrite recommendations with expected impact. Use when investigating slow queries or tuning a database under load. Trigger with "analyze query performance", "review EXPLAIN plan".
