class BetaManagedAgentsDeletedMemoryStore { Type = "memory_store_deleted"; ID; }

Confirmation that a memory_store was deleted.

JsonElement Type = "memory_store_deleted"
required string ID

ID of the deleted memory store (a memstore_... identifier). The store and all its memories and versions are no longer retrievable.

class BetaManagedAgentsMemoryStore { Type = "memory_store"; ID; ArchivedAt; /* 5 more */ }

A memory_store: a named container for agent memories, scoped to a workspace. Attach a store to a session via resources[] to mount it as a directory the agent can read and write.

JsonElement Type = "memory_store"
required string ID

The unique ID of the memory store (memstore_...). Use it to attach the store to a session.

required DateTimeOffset? ArchivedAt

When the memory store was archived, in RFC 3339, or null if it hasn't been.

Archiving can't be undone. An archived store can't be attached to new sessions. You can't create or update its memories or update the store. You can still read and delete its memories, redact their versions, and delete the store.

See the memory guide to learn more about archiving.

formatdate-time
required DateTimeOffset CreatedAt

When the memory store was created, in RFC 3339.

formatdate-time
required string Description

Free-text description of what the store contains, up to 1,024 characters. Included in the agent's system prompt when the store is attached, so word it to be useful to the agent. Empty string when unset.

required IReadOnlyDictionary<string, string> Metadata

Key-value pairs for your own use, such as the end user that the store belongs to.

A store has at most 16 pairs. Keys are 1 to 64 characters long and values at most 512 characters. You can't filter lists by metadata.

required string Name

Human-readable name for the store. 1–255 characters. The store's mount-path slug under /mnt/memory/ is derived from this name.

required DateTimeOffset UpdatedAt

When the memory store was last changed, in RFC 3339.

Changing its name, description, or metadata updates it. Archiving the store does too. Changes to the store's memories don't.
