WHAT IT DOES

What assign_patrol_route does on Sbox

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

RISK

Why assign_patrol_route is rated Medium

This tool creates or modifies game entity data (NPC behavior configuration) without irreversibly deleting anything or executing arbitrary code. It assigns a patrol route to an NPC, which is a configuration write operation.

From the tool's definition The tool description states it will 'Wire a placed route... into an NpcBrain', which modifies the configuration/state of an NPC entity by assigning a patrol route to it. This is a reversible state change to game objects.

RECOMMENDED RULE

The rule that runs assign_patrol_route safely

assign_patrol_route Rate-limited

assign_patrol_route stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
