Obviously you don’t need an LLM to prettify obfuscated JavaScript. But take a look at the repo. It didn’t just add the whitespace back — it restored the original file structure, inferred function and variable names, wrote TypeScript type definitions based on usage, and added (actually decent) comments throughout the source code. That simply isn’t possible without an LLM.
Do you have a lot of experience with minified code?
Please link to a tool that can infer function/variable names and TypeScript type definitions from minified JS without using LLMs or requiring significant user input.
Also, it's guessing at the names, guessing at type definitions, and it makes further guesses based on its previous ones, correct or no. If you don't already know what you're doing, you're in trouble.
For someone to claim that they're sharing the "decompiled" source of Claude Code for the public good is self-important back-patting nonsense, let alone misleading.
