Show HN: LLM Rescuer – Fixing the billion dollar mistake in Ruby

Summary

LLM Rescuer 🤖💰 ⚠️ EXPERIMENTAL PROJECT - NOT FOR PRODUCTION USE This project is an experimental proof-of-concept developed for educational purposes and pure, unadulterated fun. It uses AI to dynamically handle runtime errors, which introduces unpredictable behavior and potential security risks that would make your security team cry. Never use this in production environments unless you enjoy explaining to your boss why the AI decided your user's name should be "🐱 Mr. Whiskers". The Mission: Fixing the Billion Dollar Mistake... With a Billion Dollars Worth of LLM Tokens In 1965, Tony Hoare invented the null reference and later called it his "billion-dollar mistake". Well, we're here to fix it by potentially spending a billion dollars in OpenAI API tokens! 💸 Because clearly, the best way to solve a problem caused by the absence of a value is to throw artificial intelligence at it until it hallucinates a reasonable response. What could possibly go wrong? What This Abomination Does LLM Rescuer is a Ruby gem that catches your NoMethodError s when you call methods on nil and asks GPT to guess what you probably wanted. It's like having a very expensive, overly-confident intern who's read your entire codebase and thinks they know what you meant. user = nil puts user . name # Instead of crashing, might return "John Doe" or "undefined" or "🎭" # depending on what the AI thinks is funny today How This Beautiful Disaster Works The Trap: We monkey-patch NilClass because why not break fundamental assumptions? The Analysis: When you call a method on nil , we pause everything and ask an LLM to read your mind The Oracle: GPT-5 analyzes your code like a digital Sherlock Holmes with ADHD The Guess: It returns what it thinks you wanted, which is right about 73.2% of the time* The Magic: Your code continues running, probably doing something completely different than intended *Statistics may be made up Installation (AKA "How to Spend Your OpenAI Credits") Add this line to your application'...
