List all threat actors, malware families, and other entities currently on
AI agents call watchlist.list to retrieve information from OPTIX: Operational Platform for Threat Intelligence Exploration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns watchlist data without creating, modifying, deleting, or executing any actions. It is a straightforward read operation that retrieves information about monitored threat entities. The low severity reflects minimal risk from misuse—an AI agent listing watchlist contents poses no direct operational harm.
