This looks really cool and is something I would love to check out, but the permissions of the actual app seem pretty high. For us, our code is stored in a private repository with no plan for any public release. Permissions for Zube are asking to not only read the private repository code, but also have write access to them as well. There's also requests to read/write web service hooks, deploy keys and pull requests. Is this a byproduct of Github's design or does the app really need all of these permissions to function properly?
