How I Built a Production-Grade Tool with Claude Code - And Kept the Architecture Honest Across Weeks of Sessions

A methodology for keeping AI-assisted projects honest across weeks of sessions Most developers who use Claude Code for anything beyond a single file have hit the same wall. You spend a week building something real. The architecture is in your head. The decisions are in your head. The tradeoffs are in your head. Then you start a new session and Claude Code starts cold, with no memory of any of it. You paste some context, it gets going, and three hours later you realize it quietly drifted from the design you spent days thinking through. Nothing broke. The tests pass.
