Every developer using Claude Code hits the same wall: you spend 30 minutes building context, explaining your project structure, walking through the codebase... and then the session ends. Next time? Start from zero.

I've been using Claude Code daily for the past 2 months, and I've tried pretty much every approach to solve this. Here's what actually works.

The Problem

Claude Code sessions are stateless. Each new session starts fresh — no memory of your previous conversations, your project preferences, or the debugging journey you went through yesterday.

Re-explaining your tech stack

Re-establishing coding conventions

Losing the context of multi-session refactoring work

Forgetting what prompts worked well before
