Ah, that makes sense. I was wondering why there was both a “!sum” AND a “!sumk” bang if they both just did the same thing.
The easiest solution seems to be to just making a custom bang to override “!sum” to differentiate it from “!sumk.” I’m guessing just doing a custom override makes the most sense in general, that way you keep the default to what's used the most (thereby reducing costs) and since users can override to do other things like get a target language as well (no need to make default bangs for different languages, etc.)
For anyone else who’s interested, the custom bang I set for !sum is https://kagi.com/summarizer/index.html?url=%s&target_language=EN&summary=summary
On a side note, is there a simple heuristic for when people tend to use Key Moments vs. Summary? I found I tend to use Key Moments if I’m trying to answer a specific question from the document or site, but that I use Summary when trying to figure out if a particular e.g. long-form article or paper is worth reading at all.
