SKILL.md

This skill helps you write migrations that avoid blocking reads/writes in production. Based on Squawk linter rules.

After writing a migration, verify it with the Squawk CLI:

| Add column with default | ADD COLUMN x INT DEFAULT 1 NOT NULL (PG <11) | Add nullable, set default, backfill, then add NOT NULL | | Add NOT NULL to existing column | ALTER COLUMN x SET NOT NULL | Add CHECK constraint NOT VALID, validate, then SET NOT NULL |

Escriba migraciones PostgreSQL seguras que eviten el bloqueo de lecturas/escrituras. Úselo al crear migraciones, agregar columnas, índices, restricciones o modificar tablas. Basado en las reglas de linter de Squawk. Fuente: frizzle-chan/mudd.
