`syntax.type_parent_required`

Type has no base.

Area 2, Values and types; not declinable; the next step is usually the agent's.

example

type BoxSize = {    width: Int}

jadpo checkcheck failed: 1 error, 1 file

error BoxSize needs a base type

--> main.jadpo:1:16

  |1 | type BoxSize = {  |                ^ expected a base before `{`

reason: Every type is written type Name = Base { ... }; the base says what it is built from, such as Object, Enum, Input or Text.
next: Add the base before {, for example type BoxSize = Object { (agent)
