AI agents call list_recent_briefs to retrieve information from QuReDec 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 existing decision briefs without modifying, executing, or deleting anything.
