SboxSuperuser/Engine/CommandDiscovery/HandlerSignature3.cs
A generic command handler signature validator for handlers taking three typed parameters. It checks that a provided MethodDescription can be closed into a delegate either returning CommandResult or Task<CommandResult> by attempting to create the corresponding delegate without invoking it.
