Teach cross-session memory patterns using MEMORY.md — what to save, how to organize it, how to maintain it over time, and how to structure topic files as memory grows. Works in any Claude Code project with no external dependencies. Trigger words: remember this, save for later, across sessions, persistent memory, don't forget, note this, keep this, write this down.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# agent-memory — Cross-Session Memory Patterns for Claude Code
Claude Code has no memory between sessions by default. Every conversation starts blank. But a project's knowledge accumulates — commands discovered, patterns debugged, preferences revealed, mistakes made and corrected. Without persistence, that knowledge is lost every time the window closes.
This skill establishes a simple, durable memory pattern using a single file: `MEMORY.md`.
---
## The Core Pattern
One file. Written by the agent. Read at session start.
```
.claude/
MEMORY.md # The agent's persistent knowledge base
identity/ # Optional: separate identity files (see agent-identity skill)
memory/ # Optional: topic files as memory grows
debugging.md
deployment.md
user-preferences.md
```
---
## Setting Up MEMORY.md
Create `.claude/MEMORY.md` with this structure:
```markdown
# [Project/Agent] Memory
> This file persists across sessions. Write here when you learn something
> worth remembering. Remove entries that become outdated. Keep it useful,
> not comprehensive.
## Project Patterns
[Commands, scripts, conventions specific to this project]
## Tools & Scripts
…Read the whole file at its exact version.
How to install
mdr add jkheadley/instar/agent-memory@sha256:35d6b194efbc63d3The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
