Returns

class BetaManagedAgentsMemory: …

A memory object: a single text document at a hierarchical path inside a memory store. The content field is populated when view=full and null when view=basic; the content_size_bytes and content_sha256 fields are always populated so sync clients can diff without fetching content. Memories are addressed by their mem_... ID; the path is the create key and can be changed via update.

id: str

Unique identifier for this memory (a mem_... value). Stable across renames; use this ID, not the path, to read, update, or delete the memory.

content_sha256: str

Lowercase hex SHA-256 digest of the UTF-8 content bytes (64 characters). The server applies no normalization, so clients can compute the same hash locally for staleness checks and as the value for a content_sha256 precondition on update. Always populated, regardless of view.

content_size_bytes: int

Size of content in bytes (the UTF-8 plaintext length). Always populated, regardless of view.

formatint32

created_at: datetime

A timestamp in RFC 3339 format

formatdate-time

memory_store_id: str

ID of the memory store this memory belongs to (a memstore_... value).

memory_version_id: str

ID of the memory_version representing this memory's current content (a memver_... value). This is the authoritative head pointer; memory_version objects do not carry an is_latest flag, so compare against this field instead. Enumerate the history via List memory versions.

path: str

Hierarchical path of the memory within the store, e.g. /projects/foo/notes.md. Always starts with /. Paths are case-sensitive and unique within a store. Maximum 1,024 bytes.

type: Literal["memory"]

updated_at: datetime

A timestamp in RFC 3339 format

formatdate-time

content: Optional[str]

The memory's UTF-8 text content. Populated when view=full; null when view=basic. Maximum 100 kB (102,400 bytes).
