Refresh and get current status of all locks
AI agents call sync_all_locks to retrieve information from Home Controller without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves the current state of smart locks without modifying their configuration or state. Even though it polls/refreshes lock status, the action is read-only and informational. No locks are unlocked, locked, or altered. The blast radius of misuse is minimal—an adversary learns lock states but cannot manipulate physical security directly through this tool alone.
From the tool's definition Tool name 'sync_all_locks' and description 'Refresh and get current status of all locks' indicate a status query operation.
