Frequently asked questions
Are remote $refs supported?
No. The tool is offline and only parses local fragments.
Which schemas are supported?
Common type, properties, required, items, enum, oneOf/anyOf/allOf, and local definitions.
What about unknown keywords?
Known structure is used; an uninferable type fails strictly.
