Returns ​

  • data: optional array of BetaManagedAgentsMemoryListItem

    One page of results. Each item is either a memory object or, when depth was set, a memory_prefix rollup marker. Items appear in the requested order_by/order.

    • BetaManagedAgentsMemory object { id, content_sha256, content_size_bytes, 7 more }

      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: string

        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: string

        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: number

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

      • created_at: string

        A timestamp in RFC 3339 format

      • memory_store_id: string

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

      • memory_version_id: string

        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 full history via List memory versions.

      • path: string

        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: "memory"

        • "memory"

      • updated_at: string

        A timestamp in RFC 3339 format

      • content: optional string

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

    • BetaManagedAgentsMemoryPrefix object { path, type }

      A rolled-up directory marker returned by List memories when depth is set. Indicates that one or more memories exist deeper than the requested depth under this prefix. This is a list-time rollup, not a stored resource; it has no ID and no lifecycle. Each prefix counts toward the page limit and interleaves with memory items in path order.

      • path: string

        The rolled-up path prefix, including a trailing / (e.g. /projects/foo/). Pass this value as path_prefix on a subsequent list call to drill into the directory.

      • type: "memory_prefix"

        • "memory_prefix"

  • next_page: optional string

    Opaque cursor for the next page (a page_... value), or null if there are no more results. Pass as page on the next request.
