{
  "context": "Evaluates whether the solution wires @babel/plugin-syntax-class-properties into Babel config-based and programmatic transforms so class field syntax parses cleanly without altering class definitions. Scoring focuses solely on correct usage of the syntax plugin alongside @babel/core APIs for the specified functions.",

  "checklist": [
    {
      "name": "Config wiring",
      "description": "parseWithConfig loads the provided Babel config and that config explicitly includes @babel/plugin-syntax-class-properties in its plugins so class fields (public, static, private) and private methods parse without syntax errors.",

      "name": "Inline plugins",
      "description": "transformSnippetInline calls @babel/core programmatic APIs (e.g., transform/transformSync/transformAsync) with @babel/plugin-syntax-class-properties in the inline plugins array rather than relying on external config files.",

      "name": "Syntax-only use",
      "description": "Solution refrains from using transform plugins (e.g., @babel/plugin-transform-class-properties) and preserves class field syntax in emitted code, reflecting the syntax-only intent of @babel/plugin-syntax-class-properties.",
