One CLI Command Exposed My Entire Project Architecture

Last week I opened CLAUDE.md, stared at it for 30 seconds, typed "Next.js app with Postgres and Drizzle," and closed the file. That was my entire context file. Three seconds later I asked Claude to add an API endpoint, and it hallucinated an import path that doesn't exist in my project - because "Next.js app with Postgres" tells it almost nothing. The truth is, a useful context file needs your import graph, your database tables, your environment variables, your export catalog - the structural DNA of your project. Nobody writes that by hand.
