Portable markdown memory: CoALA working / semantic / episodic / procedural, plus optional personas as core. Use when a task spans sessions or compaction, when the user says remember / forget / preference / memory / persona / handoff, when something was learned or failed, or when the agent may forget. Also /agent-memory.
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 A longer context is not a smarter agent. Memory is a small set of markdown files. Any agent that can read and write files can run this. No database, no vector store, no host-specific APIs. This follows the industry map, not a fifth cognitive type: CoALA's four duties (Sumers et al., 2023); Letta/MemGPT core vs archival; Claude Code's MEMORY.md index + on-demand topic files. Personas is the optional always-on collaboration contract (Letta's persona/human block). ## 80% this covers Keep or resume a task after compact. Remember a confirmed fact or preference. Don't repeat a known failure. Follow how this user wants work done. Point at a verified procedure. Forget on request. Out of scope: chat archives, RAG corpora, knowledge graphs, multi-user ACL stores, auto-extract-everything, host transcripts. ## Drawers Root: `.agents/memory/` (project default). Use `~/.agents/memory/` only when the user asks for cross-project state. Do not sync the two. | Layer | Drawer | Answers | Signature | Load | |---|---|---|---|---| | Core | `personas/` | How this user wants work done | Optional. Evidence-gated. One active file. | Boot, if INDEX has a row | …

How to install
mdr add labs21-dev/agents-stack/agent-memory@sha256:167924eac8a8f46eThe line at the top of this page pins the label git:20260918.45cbe6b, 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.
