Gemini CLIAbout this skill
MongoDB schema migration safety reviewer and migration script generator. ALWAYS use when writing, reviewing, or planning MongoDB schema changes — field additions/removals, index builds, schema validator changes, document type migrations, shard key modifications, or any bulk update touching production collections. Covers index build lock behavior (foreground vs rolling builds), additive schema evolution, id-range batched updates, write concern tuning during migration, reshardCollection (5.0+), collMod validator changes, and rollback planning. Use even for "just add a field" — MongoDB's schema-less nature makes silent type inconsistencies and missing-field bugs harder to detect than RDBMS constraint violations.
