1. LangChain Publishes Guide on Building Continuous Agent Memory

LangChain. A new LangChain blog post walks through building a self-improving memory loop for AI agents using LangSmith’s Observability, Engine, and Context Hub tools. The system captures execution traces, analyzes them to identify patterns and failures, then writes learnings back into long-term memory — covering semantic, episodic, and procedural memory types. The piece positions LangSmith’s toolchain as a way to automate this feedback cycle so agents improve over time without manual intervention. Source
