How to Give Your AI Coding Agent Persistent Memory in 30 Seconds

Your AI coding agent doesn't remember yesterday. You spent an hour debugging a tricky race condition, the AI understood every nuance — and this morning it asks you to "explain the project architecture." Again. By the end of this post, you'll have persistent memory working across sessions in under 30 seconds. I'll show you the exact terminal output at every step so you can follow along.
