https://github.com/stoplightio/spectral is an open source linting tool for APIs, specifically those described using https://www.openapis.org/ (formerly known as Swagger) and API definitions, developed by Stoplight. The tool is a linter that can be used to enforce rules and standards on JSON and JSON Schema documents.

Once you have fixed any linting errors, you will need to re-run Spectral to verify that your API definition passes the linting process.

To ensure that your API definition meets the standards specified by Spectral, you may need to edit the API definition file accordingly.

Overall, Spectral linting is an invaluable tool for any developer looking to create an OpenAPI document that is secure, of high quality, and reliable.
