According to players (I haven't had time to test this yet), skins are not retained on trade. This creates a bit of a problem when you run plugins that associate importance to the skin an item is using. If the skin is stripped out, the value of the item changes.

If true then this is a Rust bug when moving items from one container to another.  This plugin doesn't track specific items but rather just containers (as opposed to Bank for example).

Ok thanks for the response.

I'm guessing it would take considerable time, but if you ever did decide to track specific items, I wouldn't be upset about it :)
