agent-memory

Agent memory and knowledge management with 4-layer cognitive architecture

Part of the AumOS open-source agent infrastructure portfolio.

Features

• Four-layer cognitive memory model — WORKING (active context), EPISODIC (events), SEMANTIC (facts and concepts), and PROCEDURAL (how-to knowledge) — each with its own storage, retrieval, and eviction semantics
• Importance scoring with five qualitative tiers (CRITICAL through TRIVIAL) and a numeric [0, 1] score, plus time-based decay that reduces importance automatically as memories age
• Contradiction detection and resolution: ContradictionDetector identifies conflicting MemoryEntry pairs and ContradictionResolver applies configurable resolution strategies
• Provenance tracking records the source and trust level of every memory item, with reliability scores that factor into retrieval ranking
• Three storage backends — in-memory, SQLite, and Redis — all behind the MemoryStore ABC; UnifiedMemory provides a single facade across all four layers
• AutoMemorizeMiddleware and ContextBuilder work together to automatically memorize tool outputs and construct retrieval-augmented context windows for LLM calls
• Freshness validation and forced refresh policies prevent stale semantic memories from being surfaced in time-sensitive retrieval queries
