Hello,
The client library console can be found here: http://localhost:4502/libs/granite/ui/content/dumplibs.html. This console lets you see all the clientlibs on your instance, their dependencies, their embed and where the source files are in the JCR.
If you look at the top you will see three links allowing you to:
- Generate include tags for libraries of your choice
- Check the validity of your clientlibs
- Invalidate the cache and/or rebuild all clientlibs

If you click on the second link (or go to http://localhost:4502/libs/granite/ui/content/dumplibs.validate.html) you will see a list of clientlibs which have inconsistencies (missing dependencies, embeds, wrong categories, etc)
