Create a memory store

Parameters
--name: string

Body param: Human-readable name for the store. Required; 1–255 characters; no control characters. The mount-path slug under /mnt/memory/ is derived from this name (lowercased, non-alphanumeric runs collapsed to a hyphen). Names need not be unique within a workspace.

minLength1
maxLength255
--description: optional string

Body param: Free-text description of what the store contains, up to 1024 characters. Included in the agent's system prompt when the store is attached, so word it to be useful to the agent.

maxLength1024
--metadata: optional map[string]

Body param: Arbitrary key-value tags for your own bookkeeping (such as the end user a store belongs to). Up to 16 pairs; keys 1–64 characters; values up to 512 characters. Not visible to the agent.

--beta: optional array of AnthropicBeta

Header param: Optional header to specify the beta version(s) you want to use.

Returns
beta_managed_agents_memory_store: object{ id, created_at, name, 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.
