| Full Fuzzer Name | TopLevelElementsLinterFuzzer |
| Log Key | TLEL |
| Description | This fuzzer will check that the OpenAPI spec contains the recommended top level elements: "info.title", "info.description", "info.version", "info.contact.name", "info.contact.email", "info.contact.url", "servers", "tags". |
| Enabled by default? | No. You need to use the cats lint ... sub-command. |
| Target contract elements | OpenAPI contract metadata and structures relevant to this rule. |
| Expected result | success when no violation is found; error when the rule is violated. |
| Fuzzing logic | Inspects the OpenAPI contract without sending HTTP requests and reports violations of this rule. |
| Conditions when this fuzzer will be skipped | None; the linter runs once for the supplied contract. |
| HTTP methods that will be skipped | N/A — no HTTP requests are sent. |
| Reporting | Reports error if the OpenAPI spec does not contain at least one of the recommended top elements, or success otherwise. |
