Return all memory entries tagged with a specific topic, newest first.
AI agents call get_topic_memory to retrieve information from Metis Public Health without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing memory entries filtered by topic tag. It performs a read-only operation that returns data without side effects, altering state, or executing external actions. The word 'Return' confirms data retrieval. No data is created, modified, deleted, or executed.
