Wikipedia:Core bots

This page aims to list bots that are sufficiently critical to the project. I'm loosely defining "core" as whether the bot disappearing would cause noticeable disruption to the encyclopaedia, some significant backroom process (such as AIV), or if the loss of the bot would otherwise meaningfully impact the quality of articles. (Feel free to replace this with a more well-defined definition.) Ideally this shouldn't be a long or exhaustive list of bots.

The intention of this is to help us understand (and hopefully improve) our bus factor for these bots, should the operator become unavailable.

For each category, key bots in the area are listed, along with some comments which address the following questions:

• Does the bot have a succession strategy?
• Are they hosted on Toolforge, ideally with multiple maintainers? In that case, handover could be done by the Toolforge committee
• Is the source available?
  • If so, does it look like the source can be easily ran by another user? Or are files needed for execution missing / source is out-of-date?
  • How easily could the bot be maintained (and not just ran) by another person? Considerations/factors involved in this include: is the code a modern tech stack, and likely to be comprehensible by another bot operator? Does the bot rely on technology that is unlikely to be familiar to another potential bot maintainer (for instance, ClueBot NG uses ANNs and moreso uses a C++ framework for ANNs that is not common to use these days, compared to PyTorch etc).

This list is definitely not complete! Please help by adding a bot below.
