If the bot sees a TODO or FIXME comment, it will leave a comment saying "Take the required action to fix the issue indicated by this comment". I'm asking that this be disabled. Developers tend to know that TODOs and FIXMEs should be fixed eventually, but it's not always possible or convenient to do that immediately, and a noisy bot won't change that. Whenever I see some space for improvement, I like to mark it with a TODO or FIXME, even if it's not actionable, because it's easier to find (via grep, and IDEs can even highlight such comments), and consequently, it's perhaps more likely that someone will work on it at some point. Discouraging TODOs is not good, because if you don't want to annoy the bot you may either remove the comment, or not format it as a TODO, both of which are bad options.

@Daimona Eaytoy I have made some changes to avoid alerts on "FIXME" occurrences. I'm keeping an eye out; let me know if you receive any additional alerts.
Yeah, I ignore all these for TODOs; generally FIXMEs are for issues that should be fixed before the patch is landed, though that varies by team. In our team we encourage making each inline action comment into a Phabricator task and mentioning it (so TODO: Do x becomes TODO (T123456): Do x), but that's rather specialist and maybe something we could in the longer run add to MW codesniffer, not here.
