Memory Scoping overview

Memory Scoping as a cross-cutting topic — the hierarchy of scopes at which agent memories are stored, retrieved, and isolated. Covers session-only memory (context window, dies with session), project-scoped memory (persists per-project across sessions), user-scoped memory (follows the user across projects), org-scoped memory (shared across team members), and cross-agent memory (shared across different agent products). Each scope level introduces new challenges: project-scoped memory needs project identification, user-scoped needs user identity, org-scoped needs access control, and cross-agent needs format interoperability. Claude Code implements project + user scopes, Mem0 adds agent + org scopes, and agentmemory targets cross-agent sharing.
