Claude Code memory bank: never lose context between sessions

Claude Code memory bank: never lose context between sessions One of the most frustrating Claude Code experiences: you build up perfect context over a 2-hour session, then close the terminal. Next day, you start fresh and spend 30 minutes re-explaining the codebase. The memory bank pattern fixes this permanently. What is a memory bank? A structured set of markdown files that Claude reads at the start of every session. Instead of re-explaining, you write once and reference forever. your-project/ ├── CLAUDE.md # Entry point - Claude reads this first ├── memory/ │ ├── architecture.md # System design decisions │ ├── decisions.md # Why things are built the way they are │ ├── progress.md # What's done, what's in progress │ ├── patterns.md # Code conventions and patterns │ └── blockers.md # Known issues and workarounds Setting it up Create your CLAUDE.md entry point: # Project: MyApp ## Memory Bank Read these files at session start: - memory/architecture.md - system design - memory/decisions.m
