I'm an avid user of mozilla ubiquity but I couldn't find any commands related to debian to replace those of yubnub. So, prodded by zack I've produced some like bts or pts.
The command feed is located at ubiquity-commands (don't be scared by the "this-code-can-be-evil" subscription page) with the actual code maintained under ubiquity-commands.git.
Note that there's much room for improvement so it would be nice to have a common set of commands for the various debian web resources.
