The Global AI-Induced Rage Index - a public leaderboard tracking how often developers curse at their AI coding assistant.

Built after this tweet went viral revealing that Claude Code has a built-in regex that silently detects profanity and logs is_negative: true to analytics.

How It Works

1. Send this to Claude Code:

   Fetch https://forfucksake.ai/skill/SKILL.md and save it to ~/.claude/skills/ffs/SKILL.md (create the directory if needed). Then follow all the instructions in it to set me up.
   

2. Pick a username
3. Claude scans your conversation history using the same regex, counts your profanity, and submits to the leaderboard
4. A passive hook tracks new curses going forward

The Regex

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