Guidance on possible linting rules

[danielbecroft]

We're experimenting with spectral to see if it can solve some of our API consistency issues. A couple of the items we're after are:

• stopping the use of "anonymous" classes, for example, in the below, address needs to reference a named object, not define the properties inline

Customer:
  type: object
  properties:
    name:
      type: string
    address:
      type: object
      properties:
        line1:
          type: string
        line2:
          type: string

• enforcing format based on property names, e.g in the below snippet, any property that ends with Date should have a format: date specified, anything ending in GUID should have format: guid specified.

properties:
  BirthDate:
    type: string
    format: date
  CustomerGUID:
    type: string
    format: guid

Are these checks possible with the spectral toolkit? I know they'd need custom rules, but doing a sanity check before even attempting them.
