This is a proper memory architecture for Claude, not just a flat file. You get four stores (episodic, semantic, procedural, vault) with natural language triggers like "remember this" or "forget that." It handles decay scoring so old memories fade unless accessed, runs reflection cycles where Claude does internal monologue about what happened, and tracks everything through git for audit. The reflection system is interesting: Claude requests token budgets, writes stream-of-consciousness self-examination, and updates its self-image over time. Built for multi-agent setups with shared read and gated write. If you're tired of agents forgetting context or want something closer to how humans actually remember things, this replaces the basic MEMORY.md approach with something architectural.
