Returns

class BetaManagedAgentsMemory { 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.

Create a memory

require "anthropic"

anthropic = Anthropic::Client.new(api_key: "my-anthropic-api-key")

beta_managed_agents_memory = anthropic.beta.memory_stores.memories.create("memory_store_id", content: "content", path: "xx")

puts(beta_managed_agents_memory)
