Unfortunately Eagle doesn't seem to store a description per device, only
per set of devices, and also for the library containing it.

Looking at what it does store in the schematic file per device, I think one
possibility might be to add an APPROVED attribute in the Technology section
(where some of the CADSoft-supplied libraries store Farnell etc part
numbers and other assorted metadata) when you've approved a device, and
then search on that. This would be quite easy to then write an audit tool
for. I've already extended the aforementioned Ruby gem to parse that part
of the schematic (and various other parts).

Alternatively, you can add a description to a package. If you're reusing
the same package for a variety of parts (eg. the same 0805 footprint for C
and R) this might make sense. But it's not quite as sane for parts where
you may reuse the same package for many devices but the pinout *also* needs
to be approved, eg. TO-92 or ICs.
