How I built a GitHub account switcher using Claude Opus 4 to write prompts and Claude Sonnet 4 to execute them.
The Magic Trick Has a Secret
Watch my 2-minute video and you'll see what looks impossible: Claude Sonnet 4 in Windsurf AI IDE takes my prompt and builds a complete browser extension.
GitHub's annoying 3-click account switching becomes a clean 1-click dropdown.
TypeScript, manifest v3, perfect styling, all generated in real time. But here's the truth: those 2 minutes of execution required hours of prompt engineering using Claude's Projects feature as my personal AI training ground.
The breakthrough isn't speed… it's precision. I used Claude Opus 4 to write the perfect prompt, then Claude Sonnet 4 to execute it flawlessly.
This AI-to-AI workflow changes everything about how I approach complex coding tasks. Instead of fighting with documentation and debugging for hours, I spent time crafting clear instructions. The result?
A production-ready browser extension that actually solves a real problem millions of developers face daily.
The lesson is simple: great prompts beat great coding skills when working with AI.
P.S. I'm kidding. 😂 I almost finished the prototype, after a couples of extra prompts, and I still need to provide unit testing and more tweaking.
