# Django Safe Migration

> Write, review, and rewrite Django migrations for PostgreSQL with zero-downtime guarantees.

Write, review, and rewrite Django migrations for PostgreSQL with zero-downtime guarantees. Use this skill whenever the user mentions migrations, Django schema changes, or deployment safety — even if they don't say "zero downtime" explicitly. Trigger on: "review this migration", "is this migration safe?", "write a migration for...", "rewrite this migration", "how do I add a NOT NULL column / drop a column / add an index / rename a column / add a FK without downtime", "will this migration cause locks?", "this migration is blocking production". Covers: SeparateDatabaseAndState two-file splits, AddIndexConcurrently, FK NOT VALID + VALIDATE, db_default for NOT NULL columns, lock_timeout, and RunPython safety rules.
