Discover existing teams in ~/.claude/teams/
AI agents call teammate_discover_teams to retrieve information from Claude Flow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only discovery operation on local team configurations. It retrieves information about existing teams but does not create, modify, or delete anything. The blast radius of misuse is minimal—an attacker could learn about team structure but cannot alter it or execute arbitrary operations. Classified as Read with low severity.
