Show HN: An AI "senior engineer" that crafts specs before vibe coding

I built an AI senior engineer that helps you craft specs for coding tools like Cursor so you can get the code you want with fewer retries.

I was getting frustrated with AI coding tools. They’re good at spitting out code, but they also make aggressive assumptions, generate a lot of unnecessary stuff, and often ignore existing functions. I kept ending up spending more time debugging than building.

So I thought: what if I had a tool that forced me to plan first? One that could use the context of my codebase and project docs, push back when I was vague, and help me write a clear spec before I let the AI start coding.

I’ve been dogfooding it for a week. It’s already made me less frustrated with AI-generated code because it points out things I should consider and produces specs that tell me exactly which file or method needs to change.

It’s still very early, but I’d love feedback, and also tips on how you approach “vibe coding” in a better way.
