Look, I've been using Claude Code for a few months now and I just realized most people are doing it backwards. Everyone's just throwing vague prompts at it like "build me a login system" and then spending forever going back and forth fixing stuff. There's a better way. Write the damn spec first. I'm serious. Before you even open Claude Code, spend 20 minutes writing out what you actually need. Requirements, edge cases, how the API should work, what errors to handle. Just a markdown file. Nothing fancy. Then (and this is the part nobody talks about) you point Claude Code directly at that spec file. "Implement the auth service in auth-spec.md." That's it. What happens next is honestly kind of wild. It reads the whole thing, sometimes asks you questions if something's unclear, then just builds it. Multiple files, proper error handling, tests that actually make sense. Because it knows exactly what you want. No more asking - actually can you change this fifteen times. No more - I forgot to mention we need to handle OAuth too. The spec is right there. And here's the thing that sold me: your specs don't disappear into some Google Doc graveyard. They live with your code. When you need to refactor three months later, the spec is still there telling you what the hell you were thinking. Try it once. Write a proper spec, save it as a .md file in your project, and tell Claude Code to build from it. You'll get why everyone who does this won't shut up about it.

So I grabbed coffee with my buddy Rohan last week, and his story is kind of wild. He's been sitting on this enterprise SaaS idea in the HRTech space for months. Good idea too - validated with potential customers. But he can't code much. So he started getting quotes. The developer route? > Senior devs wanted $120K-150K a year plus equity. Even juniors were $80K+. But it's not just the salary - it's the commitment. What if it doesn't work? He was worried about bleeding cash every month on payroll while trying to figure out if anyone will pay for his product. Dev agencies? > Cheapest quote: $23,000. Most expensive: $47K. Timeline? 3-4 months. And any changes after delivery? Extra. Always extra. Then he found this AI coding thing. He took a $500 course on Agentic spec coding - basically using specialized AI agents to build software without being a developer. A month later, he had a working MVP. Not a prototype. An actual product he's testing with real users. The math: - Devs: $120K+ per year - Agency: $23K, months of waiting - His way: $500, one month What surprised him most: The speed, flexibility, and scalability. With an agency, every change takes days or weeks of negotiation. Now he iterates in hours. Idea in the morning, tested and fixed by dinner. This isn't magic. Rohan had frustrating nights because of the lack of experience with spec coding. Things broke. You still need to understand what you're building - the AI doesn't think for you. But if you're scrappy? This is viable. Three years ago, non-technical founders had to learn to code for years or raise money. Now there's another path. Not replacing developers for complex stuff, but for getting an MVP out there? Completely different game. Rohan's product isn't perfect. But it exists. People are using it. Built for the cost of a used iPhone and a month of late nights. What would you build if you didn't need to raise $500K first?
