It performs no mutations, deletions, or external operations. The data returned is informational (league associations) with no capability to modify, delete, or execute actions. Low severity because disclosure of league membership is minimal risk in a public sports API context. From the tool's own definition: "Tool description explicitly states 'List the NFL leagues' - a retrieval operation with no modification or side effects. The verb 'List' is a classic read-only query pattern." ## Use case AI agents call sleeper_get_user_leagues to retrieve information from Sports Hub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
