Read a slow query's execution plan and turn it into a concrete fix — the exact index to add, the rewrite, or the ANALYZE to run — by getting the REAL plan with EXPLAIN ANALYZE (actual rows + timing, not estimates), finding the offending node, and confirming the fix removes it. Use when one specific query is slow and you need to know WHY, not just that it is.

From the source SKILL.md

A slow query is almost never slow for the reason you'd guess from reading the SQL. The plan is the ground truth: it shows the database actually chose a Seq Scan over the 40-million-row table, actually fed 500,000 rows into a Nested Loop that estimated 5, actually sorted on disk because no index could supply the order. This skill pulls the real plan — EXPLAIN ANALYZE with BUFFERS, not bare EXPLAIN — reads it from the most expensive node outward, names the one node that's costing the time and why, and turns that into a specific fix: the index to add (with the right column order), the rewrite…
