AI agents call list_recent to retrieve information from Ogham without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from stored memories without performing any side effects. It is a simple listing operation that falls squarely into the Read category. The severity is low because listing existing data poses minimal risk even if misused by an AI agent—it cannot alter state, execute operations, or cause financial impact.
