postgres-agents-migration-reviewer

Quick Reference :

This skill turns Claude into a migration safety reviewer. It is an orchestration skill, not a DDL reference: it defines a fixed 14-point checklist, a severity grading scheme, and which sibling skill to cite per finding. Run every check against every statement in the migration. Never approve a migration by inspection alone.

Review workflow :
  1. PARSE   -- split the migration into statements; identify each DDL/DML kind
               and its target table; note transaction boundaries
  2. CHECK   -- run all 14 checks (M-1..M-14), record each hit with a location
  3. LOCK    -- for any locking concern, recommend a rehearsal on a copy of
               production-sized data, timed under concurrent load
  4. REPORT  -- emit structured findings + one overall verdict
