Currently, gosec supports the #nosec annotation comment, but in Go, comments in the form of //toolname:directive are officially recognized as directive comments.

A directive comment is a line matching the regular expression //(line |extern |export |[a-z0-9]+:[a-z0-9]). Tools that define their own directives should use the form //toolname:directive.

Tools like gofmt and pkgsite (godoc) recognize directive comments in this format.
By supporting officially formatted directive comments, gosec can also benefit from this standardized approach.

For example:

//gosec:disable G402
