-### Body Parameters
+## Body parameters
 
 - `content: string or null`

from line 106

 
   Hierarchical path for the new memory, e.g. `/projects/foo/notes.md`. Must start with `/`, contain at least one non-empty segment, and be at most 1,024 bytes. Must not contain empty segments, `.` or `..` segments, control or format characters, and must be NFC-normalized. Paths are case-sensitive.
 
-### Returns
+  minLength: 2, maxLength: 1024
 
-- `BetaManagedAgentsMemory object { id, content_sha256, content_size_bytes, 7 more }`
+## Returns
 
+- `BetaManagedAgentsMemory object`
+
   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`

from line 126

 
     Size of `content` in bytes (the UTF-8 plaintext length). Always populated, regardless of `view`.
 
+    format: int32
+
   - `created_at: string`
 
     A timestamp in RFC 3339 format
 
+    format: date-time
+
   - `memory_store_id: string`
 
     ID of the memory store this memory belongs to (a `memstore_...` value).

from line 148

 
   - `type: "memory"`
 
-    - `"memory"`
-
   - `updated_at: string`
 
     A timestamp in RFC 3339 format
 
+    format: date-time
+
   - `content: optional string or null`
 
     The memory's UTF-8 text content. Populated when `view=full`; `null` when `view=basic`. Maximum 100 kB (102,400 bytes).
