Given that you're the author/maintainer of the tool I think we can grant you push access to the Diffusion repository. Depending on the method you wish to push changes to the repo you'll need to create an HTTPS password or upload your SSH key to https://phabricator.wikimedia.org/settings/user/maskaravivek/
Please note however that push means your changes will go directly to the repo without any code-review.
Yes, I have already added my ssh keys to phab.
Yes, I understand that it would mean direct pushes to master without code reviews. We will streamline the process to include diff reviews when there are more collaborators.
labs/tools/Commons-twitter-bot looks to be a different project than what tool-commons-android-app is supposed to be.
tool-commons-android-app would be used for hosting any APIs that are not officially exposed by MediaWiki and is required by the Commons Android App. Right now there's a requirement to expose the number of reverts by a user which isn't returned by any official API.
Moreover, toolsadmin.wikimedia.org automatically created the project on phabricator when I chose to create a new project. Correct me if I am wrong in assuming that all tools projects are by default hosted on phabricator.
