AI agents call suggest_links to retrieve information from Engram without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries existing memory data to provide suggestions. It retrieves and analyzes information to recommend relationships but does not create, modify, delete, or execute any operations. No data is changed, no external operations are triggered, and the impact is purely informational.
From the tool's definition Tool description states it 'Analiza memorias y sugiere posibles enlaces sin crearlos' (analyzes memories and suggests possible links without creating them).
