One thing to be mindful of is that NS_PROJECT includes discussion pages (village pumps, article deletion discussions, RfCs, nominations for advanced permissions etc) and those are not very useful for chatbot answers (with the exception of specifically help-focused pages like the teahouse or the help desk) and often quite toxic.

Thanks for participating in the Hackathon! We hope you had a great time.

• If this task was being worked on and resolved at the Hackathon: Please change the task status to resolved via the Add Action... → Change Status dropdown, and make sure that this task has a link to the public codebase.
• If this task is still valid and should stay open: Please add another active project tag to this task, so others can find this task (as likely nobody in the future will look back at the Hackathon workboard when trying to find something they are interested in).
• In case there is nothing else to do for this task, or nobody plans to work on this task anymore: Please set the task status to declined.

Thank you,
Phabricator housekeeping service

There is an experimental chatbot, although it seems to be more geared towards article writing: https://en.wikipedia.org/wiki/User:Phlsph7/WikiChatbot
