How I Stopped Re-Explaining Everything to Claude Code Every Single Session

How I Stopped Re-Explaining Everything to Claude Code Every Single Session Every time I started a new Claude Code session, I spent the first 5-10 minutes doing the same thing: "Here's what we're building..." "You prefer direct communication, no filler..." "We're using this stack, this naming convention..." "Last time we got stuck on X, we decided to do Y..." It was like onboarding a new employee every morning. Except the employee was brilliant, I just had no way to give them a briefcase full of institutional knowledge before they sat down. After months of frustration, I built a system that fixed this. Here's how it works. The Problem: Every Session Starts from Zero Claude Code (and most AI coding agents) don't retain memory between sessions. Each conversation is a clean slate. That's fine for a one-off question, but if you're building something real — a product, a tool, a side project — you end up re-establishing context over and over. The problem compounds. You forget what you told it
