Those are the correct return values from goal-focus and buffer-chunk 
(when it is given a buffer name).  Goal-focus returns the name of the 
chunk in the goal buffer, and buffer-chunk returns a list of the names 
of the chunks in the buffers specified.  The output to the command-trace 
with the buffer's chunk information is a side effect of calling those 
commands, and you will see that when you call it remotely as well.

If you want to know what slots a chunk has, then you would use the 
chunk-filled-slots-list command passing it the chunk's name, and it will 
return a list of the slots it has. If you want to know what the value of 
a slot in a chunk is then you need to use the chunk-slot-value command.  
It requires the name of the chunk and the name of a slot, and then 
returns the value in that slot of that chunk.

Hope that helps,

Dan
