🗄️ database — Unified Database Department

One head skill for all database work. Query read-only, diagnose the slow query, index what matters, guard the rows, keep production healthy. Every mode runs handsfree — defaults are stated inline, assumptions recorded in the deliverable, zero questions asked.

Default stack: self-hosted Postgres 16+ with pg_stat_statements enabled for the diagnose/index/guard/operate modes; the query mode works with any SQL database that has a connection config. Supabase-approved references linked per mode where applicable. Supabase platform operations (dashboard, Auth service, Edge Functions) are linked out, never duplicated.

Modes — quick commands

Every invocation resolves to exactly one mode. Match the request, then load only the matched reference:
