WHAT IT DOES

What delete_script does on Ha Nexus Agent

AI agents call delete_script to permanently remove resources in Ha Nexus Agent, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_script is rated Critical

Deletion of scripts is a destructive action that cannot be undone. Once deleted, the script is removed from the Home Assistant configuration. This has high blast radius in a smart home context where scripts may control critical automations (lighting, locks, climate, security). An errant AI agent could disable essential home automation by deleting scripts, causing operational disruption or safety issues.

From the tool's definition 'Delete a script by id. Auto-reloads scripts afterwards.' — the tool explicitly deletes scripts, an irreversible operation that destroys automation logic in the smart home.

RECOMMENDED RULE

The rule that runs delete_script safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ha Nexus Agent, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_script, this is the rule to start with:

delete_script Hidden

delete_script is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.

The button opens the PolicyLayer dashboard: create your workspace, connect Ha Nexus Agent, apply this rule, and every delete_script call is checked against it from then on.
