Trigger with "remember this", "update memory", "what should we record from this session", "capture learnings", "write a session log", or when closing a session. Guides agents on managing memory hygiene across sessions, deciding what to write to dated memory logs, what to promote to long-term memory.md, and when to archive.
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
# Session Memory Manager (`os-lab-memory`) Manages the three tiers of agent memory in an Agentic OS environment: Auto-memory (`MEMORY.md`), Long-term facts (`context/memory.md`), and Session logs (`context/memory/YYYY-MM-DD.md`). ## Contents - [Critical Constraints](#critical-constraints) - [Quick start](#quick-start) - [Workflow](#workflow) - [Verification](#verification) - [References](#references) ## Critical Constraints 1. **Conflict Resolution**: Never overwrite `context/memory.md` with conflicting facts without prompt and resolution. 2. **Enduring Facts Only**: Do not promote ephemeral error messages, test noise, or single-use bash commands. 3. **Lock Release**: Always release `memory` lock upon completion or error recovery. ## Quick start Check current memory file size and status: ```bash wc -c context/memory.md ``` ## Workflow 1. **Acquire Lock**: Acquire `memory` lock via `kernel.py`: ```bash python3 scripts/kernel.py acquire_lock memory ``` 2. **Record Session Log**: Write dated session summary to `context/memory/YYYY-MM-DD.md`. 3. **Promote Long-Term Facts**: Append vetted architectural decisions to `context/memory.md` with conflict checks. …

How to install
mdr add richfrem/agent-plugins-skills/os-lab-memory@sha256:ce8e9f65227aaba5The line at the top of this page pins the label git:20261015.fe76d7e, 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.
