Claude Platform — April 23, 2026

Memory for Claude Managed Agents lands in public beta under the standard managed-agents-2026-04-01 header. Memory stores are workspace-scoped collections of text documents that mount into agent sessions at /mnt/memory/ — the agent reads and writes them with the same file tools it uses for the rest of the filesystem. Every change creates an immutable memory version (audit trail + point-in-time recovery), and a redact endpoint scrubs content out of historical versions for compliance workflows. Read-only mounts matter for security: prompt injection on a read-write store can poison later sessions.

Memory for Claude Managed Agents — public beta

Why: Each Managed Agents session started with a fresh context, so user preferences, project conventions, prior mistakes, and domain knowledge were lost when the session ended.

What: Releases public-beta memory stores for Managed Agents — workspace-scoped collections of text documents the agent reads and writes via filesystem tools, mounted under /mnt/memory/.

How: Beta header managed-agents-2026-04-01; POST /v1/memory_stores to create, then attach via the session's resources[] with type: memory_store and access: read_write or read_only.
