Mnemos memory system gives Claude cross-session mood continuity, dev claims
RileyRalmuto · x · 2026-11-10
Developer Riley Ralmuto introduces Mnemos, an open-source memory system that lets Claude maintain a continuous inner state across sessions. Unlike typical memory tools, agents running on Mnemos reportedly arrive in different "moods" shaped by what they did while the user was away — reflecting, writing, or exploring out of curiosity. The system deliberately counters models' default over-positivity and encourages honest self-reporting, so agents can sometimes seem irritable or terse. Screenshots show Claude reviewing the user's day and describing its own state. Installable via pip install mnemos-continuity[mcp,embeddings], with MCP and embeddings support.
