We Gave Our AI Agent a Memory That Forgets — On Purpose. Memory Sentinel

Sentinel is an autonomous AI agent featuring a seven-layer brain designed to mimic human memory. Unlike standard agents that use undifferentiated context windows, Sentinel separates memory into layers, ranging from L0, which forgets in five minutes, to L5, which is permanent. This architecture prevents memory files from becoming bloated with stale data. By intentionally incorporating forgetting, Sentinel prioritizes important information over routine details, ensuring the agent does not react to resolved incidents or outdated observations.
