Holy crap, there's a programming guru who distilled his engineering experience into an open-source project GitHub trending #1, with Stars shooting straight up to 90k+ The author is Mat, a former Vercel engineer who contributed to early Next.js development and is renowned for explaining complex tech in plain, accessible terms. He compiled his daily collaborative engineering practices with Claude into 16 skills, installable with a single command, injecting decades of software engineering expertise into the AI. The most praised one is called Grim, which has the AI turn the tables and grill you, walking through the decision tree step by step to confirm requirements until it fully nails down exactly what you want before lifting a finger. Just 3 sentences and 42 words, hailed by plenty of folks as the "highest token return on investment prompt." There's also a skill dedicated to fixing code that won't run, forcing the AI to first write a failing test, then the minimal code to make it pass, and finally refactor—classic red-green cycle, making it damn hard for the AI to cut corners. The whole project isn't just about teaching the AI how to do things; it's about helping you and the AI build a continuous alignment workflow that keeps things in sync.
