Docs generator considers the hyphen in @param as a bullet point

[nicolo-ribaudo]

@param foo - The foo

The JSR website will render the description as a bullet list containing "• The foo", rather than just as "The foo".

Note that the - in JSDoc is optional, but even on the JSDoc website itself it's much more common to have it than not (https://jsdoc.app/tags-param)
