Recommend the right Postgres index for a query or workload — choosing B-Tree vs. GIN vs. BRIN vs. partial/covering/expression, checking for redundant or unused indexes, and verifying the choice against the query plan. Use when a query needs an index, when deciding an index type for jsonb/array/full-text/time-series data, or when auditing an over-indexed table.

From the source SKILL.md

Most Postgres index problems are one of two mistakes: reaching for B-Tree when the column is multi-value (jsonb, array, full-text) and a GIN would be transformative, or piling on speculative indexes that tax every write for reads that never happen. This skill matches the index type to the query and the data shape, prunes the indexes that aren't earning their keep, and verifies the choice against the actual plan — so you add the index that helps and skip the one that just costs.

What this skill does

Postgres Index Strategist is a community-contributed Claude Code skill in the databases sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/postgres-index-strategist/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when a query needs an index, when deciding an index type for jsonb/array/full-text/time-series data, or when auditing an over-indexed table.
