It's great that each action performed by an OAuth consumer is tagged as such. It would also be nice if the consumer description page was a bit more user-friendly. As an example:
What I'm missing on this page:
- A link to https://commons.wikimedia.org/wiki/User:Danmichaelo
- A link to https://commons.wikimedia.org/wiki/Commons:CropTool
- A link to http://tools.wmflabs.org/croptool/
- A link to a bug reporting mechanism
- A link to the source code
The callback link in this case is identical to the tool link, but it doesn't have to be. So I'd recommend including the following in the consumer metadata:
- author URL (username URL or website)
- tool description / usage instructions URL
- tool URL
- bug reports / feedback URL
- source code URL
Once we have a bit more metadata, we can clean the special page up and make it less technical and more understandable, since we can reasonably expect users to visit these pages from the Tag: links in recent-changes/contributions.
I understand that consumers may not have all required information by the time they're requesting a token, and in some cases, not all of it will be applicable or required. So all of the above could be optional, and supplied later.
