Writing JSON Schemas for z-schema

Write correct, idiomatic JSON Schemas validated by z-schema. Default target: draft-2020-12.

Schema template

Start every schema with a $schema declaration and type:

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "properties": {},
  "required": [],
  "additionalProperties": false
}

Set additionalProperties: false explicitly when extra properties should be rejected — z-schema allows them by default.
