In this tutorial, we'll build a Discord bot that watches for code blocks in messages, reviews them with AI in a roast-style tone, and replies with brutally honest feedback. Think code review meets comedy. What we're building User : ! roast javascript function getUser(id) { var user = null; fetch('/api/users/' + id).then(res => { user = res.json(); }); return user; } Bot: 🔥 CODE ROAST 🔥 Oh no.
