Claude Managed Agents Memory: Cross-Session Guide

Anthropic just shipped Memory for Managed Agents as a public beta on the Claude Platform. It plugs a real filesystem into your hosted agent so it can write notes during one session and read them back in the next. If you have ever asked yourself “how do I make my Claude agent remember this user tomorrow?” — this is the answer, and it ships without you running a vector DB or a Redis.

In this guide you will create a memory store, pre-load it with reference docs, attach it to a session, watch the agent write its own memories, then start a fresh session and see those memories survive. End-to-end in under 20 lines of Python.
