WHAT IT DOES

What discord_set_role_position does on Discord

AI agents use discord_set_role_position to create or update resources in Discord — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Discord environment.

WHY IT NEEDS A POLICY

Why discord_set_role_position needs a policy

Repositioning a role in the server hierarchy is a reversible modification (Write), but carries high severity because role position determines permission precedence — moving a role higher can grant it elevated permissions over other roles and members, potentially enabling privilege escalation across the entire server.
