AI agents call maimemo_get_today_progress to retrieve information from Maimemo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries user progress data from a study application. It performs a simple retrieval with no side effects, no code execution, and no destructive or financial operations.
