Memory Tool
A filing cabinet the AI can write notes into and read from later, so it remembers things between sessions.
Definition
An Anthropic-provided tool (type memory_20250818) that lets Claude create, read, update, and delete files in a /memories directory that persist across conversations. It runs client-side: Claude requests file operations and your application executes them against storage you control, so knowledge carries over between sessions without staying in the context window.
Example
Claude calls view /memories, finds refund_policies.xml saved last week, and reads it before answering a new customer ticket.
