Retrieves all episodic memory entries for a product. Use to review past investigation history.
AI agents call listMemories to retrieve information from Bedrock Agent Core Operations Hub without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
listMemories performs a straightforward query operation to fetch historical investigation data. It retrieves information without creating, modifying, or deleting data, and does not trigger external operations or financial transactions. The 'Retrieves' verb and 'review' use case clearly indicate a Read category tool with minimal risk.
From the tool's definition Tool description states 'Retrieves all episodic memory entries' and 'Use to review past investigation history' - both indicate read-only data retrieval with no modification or side effects.
