WHAT IT DOES

What diary_read does on Enhanced Knowledge Graph Memory Server

AI agents call diary_read to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why diary_read is rated Low

This tool retrieves and queries existing diary entries with optional filtering. It performs no write operations, does not execute external code, does not delete data, and has no financial implications. The operation is purely informational and read-only, making it a Read category risk with low severity due to minimal blast radius if misused—the worst outcome being unauthorized access to historical information.

From the tool's definition Tool description states 'Read recent diary entries' and 'Returns entries in reverse chronological order.' The verb 'read' and the retrieval-only operation indicate no modifications, deletions, or side effects.
