+// gnostic_analyze is a tool for analyzing OpenAPI descriptions.
+//
+// It scans an API description and evaluates properties
+// that influence the ease and quality of code generation.
+//  - The number of HTTP operations of each method (GET, POST, etc).
+//  - The number of HTTP operations with no OperationId value.
+//  - The parameter types used and their frequencies.
+//  - The response types used and their frequencies.
+//  - The types used in definition objects and arrays and their frequencies.
+// Results are returned in a JSON structure.
