I worked in IT and I don't really understand all the details of this analysis, but here is a gem...

"Frustration detection via regex (yes, regex)

userPromptKeywords.ts contains a regex pattern that detects user frustration:

/\b(wtf|wth|ffs|omfg|shit(ty|tiest)?|dumbass|horrible|awful|
piss(ed|ing)? off|piece of (shit|crap|junk)|what the (fuck|hell)|
fucking? (broken|useless|terrible|awful|horrible)|fuck you|
screw (this|you)|so frustrating|this sucks|damn it)\b/

An LLM company using regexes for sentiment analysis is peak irony, but also: a regex is faster and cheaper than an LLM inference call just to check if someone is swearing at your tool."
