179k GitHub stars. An ex-Vercel engineer just open-sourced the exact AI coding workflow he uses every day. Not prompts. Not templates. A complete .claude setup with 26 production-ready skills you can clone for free. Here's what stood out: • grill-with-docs → Interviews you before writing the implementation plan • code-review → Reviews architecture, not just syntax • diagnosing-bugs → Runs a systematic debugging workflow instead of random guessing • research → Investigates primary sources before making changes • grill-me → Challenges your thinking until the plan has no weak spots • handoff → Compresses an entire coding session into a clean handoff for the next agent • writing-great-skills → Helps you create reusable AI skills that actually work The best part? These aren't tied to Claude. The workflows can be adapted to Cursor, Codex, Gemini CLI, OpenAI, Amp, Windsurf, or practically any coding agent. If you're building with AI in 2026, the advantage isn't having a smarter model. It's having better workflows. This repo is basically a free masterclass in how senior engineers collaborate with AI. Worth studying even if you never copy a single file. 🔖 Bookmark this before it disappears from your timeline. What's your favorite AI coding agent right now?
