User blog comment:DaNASCAT/Update Your CSS and JavaScript To Speed Up Your Wiki/@comment-3508190-20120824071323/@comment--20120824142747

The process of obfustication is possible to safely execute only when having the full context of the executed code - all the libraries, code dependencies and so on.

This is not possible when processing only a subset of assets - like custom wiki assets with no reference to other JavaScript they may depend on (for example when they depend on Wikia code it would not be possible).

To some extent it may be possible to obfusticate (and shorten) some variables - for example local, temporary names. If you are aware of any automated tools that operate only on such limited scope please let us know.
