I am interested in any thoughts on this pull request. I understand what the original issue was asking for but I'm wondering if notify-busy-slack-thread.ts should have been split into two files: the 100-count query and a function located in packages/core/src/modules/slack/usecases that sends a message to the internal Slack and used in add-slack-message.ts

I think in this case it is fine as it is, because the logic is not too long so it's reasonable to have all of it together

LGTM @ciaracade! I just made a minor fix by changing the order of the imports to fix the lint error, but this looks good. Curious to see how often this ends up sending a message 😂

Awesome. This was so few lines I thought I was missing something. Glad to see it get approved soon : }

@ciaracade @tomas-salgado I modified this slightly to use the reply_count that comes from the Slack webhook when a reply is sent, this saves us from having to do a DB query every time a message gets sent in the Slack. See the docs here!
