Design and implement memory architectures for agent systems. Use when building agents that need to persist state across sessions, maintain entity consistency, or reason over structured knowledge.
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
# Memory System Design Memory provides the persistence layer that allows agents to maintain continuity across sessions and reason over accumulated knowledge. Simple agents rely entirely on context for memory, losing all state when sessions end. Sophisticated agents implement layered memory architectures that balance immediate context needs with long-term knowledge retention. The evolution from vector stores to knowledge graphs to temporal knowledge graphs represents increasing investment in structured memory for improved retrieval and reasoning. ## When to Activate Activate this skill when: - Building agents that must persist across sessions - Needing to maintain entity consistency across conversations - Implementing reasoning over accumulated knowledge - Designing systems that learn from past interactions - Creating knowledge bases that grow over time - Building temporal-aware systems that track state changes ## Core Concepts …

How to install
mdr add mjunaidca/mjs-agent-skills/memory-systems@sha256:06c1188b57c8287fThe line at the top of this page pins the label git:20251222.04068a4, 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.
