Is it safe to delete fields using this skill?

The skill includes a safety check that only allows field definition deletion after you confirm the data has been migrated and is undefined in all documents.

How does the Sanity Schema Manager handle field deprecation?

It implements a safe 'ReadOnly -> Hidden -> Deprecated' pattern to ensure fields are phased out without breaking the Sanity Studio or losing historical data.

What types of Sanity structures can I scaffold?

You can use the skill to quickly create templates for document types, object types, and singleton configurations.

Does it support Sanity best practices like defineType?

Absolutely. The skill enforces the use of defineType, defineField, and ensures proper icon imports from @sanity/icons for all new schemas.

Can this skill help with Sanity data migrations?

Yes, it generates migration scripts using @sanity/migrate that iterate over documents to set new field values and unset old ones.
