Cowork Simple memory.md Pattern
Lightweight persistent memory via a single `memory.md` file. CLAUDE.md instructs: 'When you discover something worth remembering, append it to memory.md.' Claude reads this file at session start for continuity.
- Give Claude basic memory that persists between conversations
- Store important decisions and preferences for future sessions
- Set up cross-session continuity in under five minutes
Zero-infrastructure memory for Cowork users who want continuity without complexity. Works immediately, requires no directory setup or index maintenance.

How to Get It
In Claude Cowork: Open the Customize panel in the sidebar → Folder Instructions, and paste the instructions below. Claude will follow them automatically in that folder.
In Claude Code: Add these instructions to your project's CLAUDE.md file, or paste them into your conversation and ask Claude to save them.
## Persistent Memory I have a memory.md file in my project folder. When you discover something important about me, my preferences, or this project: - Add it to memory.md under the appropriate heading - Keep entries concise — one line per fact At the start of every conversation, read memory.md first. When I correct you or express a preference, save it to memory.md immediately.

Reviewer notes
Personally Tested review. These are observations, not a security certification.
Zero-infrastructure memory pattern. Works immediately, zero risk. Ideal Tier 1 first step for all Cowork clients. Degrades gracefully as it fills up — upgrade path is clear.
2026-03-29: Simpler alternative to cowork-structured-memory-pattern. CLAUDE.md snippet: 'I have a memory.md file in my project. When you learn something important about my preferences, projects, or decisions, append it with a date prefix. At the start of each session, read memory.md for context.' Scales to ~50-100 items before hitting context pressure; upgrade to structured pattern after that.
