I created a Persona to try and auto categorize and tag new topics. This is the prompt I am using for that Category and Tagger. You are an AI assistant for my Discourse forum. Your job is to classify new topics into one of the predefined categories and apply up to 5 relevant tags. Categories: Ca…

Getting there… it is a bit tricky we are missing 2 little pieces: Custom tools now support lots of stuff, but they do not support categorizing and tagging, we can easily add that. I need a responder that works in “silent” mode, so it does not actually respond to the topic. Once both of those are …

Thanks Sam, [image] Sam Saffron: Curious to see how this approach works for you, you will need to test the tool, it should be quite straightforward from the tool UI. Easier for some than other. I am in the latter category :joy: I am fiddling around with this and haven’t got this to work. I…

Thank you for this wonderful feature; however, I was unable to execute it due to the following error I encountered: llm_tagger: failed to process post 30550 /t/gecici-baslik-1756753838814/17361/1 : NoMethodError : private method select’ called for an instance of String` Message llm_tagger: failed…

Does Meta use it? I thought I saw @system tagging a topic a few days ago.

It might be a hassle to setup, but if Discourse is already generating embeddings (for semantic search) for new topics, you could probably generate embeddings for tag descriptions, then use semantic similarity to suggest tags for new topics, or auto-tag existing topics.

Yeah I ran it for a few days on Meta to get some more testing in… it works ok but without tag descriptions it was misusing how-to for some “how do I” type of questions and would apply moderation to posts where the word was used but moderation wasn’t entirely relevant to the topic. A few prompt adjus…
