WHAT IT DOES

What reload_automations does on Ha Nexus Agent

AI agents invoke reload_automations to trigger actions in Ha Nexus Agent. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why reload_automations is rated High

This tool triggers a reload/execution of automation configurations from YAML files, causing the Home Assistant automation engine to re-parse and re-apply all automation rules. It is not a simple read and not purely destructive, but it does trigger an external operation (reloading live smart home automations) whose effects depend on the current YAML content.

RECOMMENDED RULE

The rule that runs reload_automations 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 reload_automations, this is the rule to start with:

reload_automations Rate-limited

reload_automations stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "reload_automations": {
      "limits": [
        {
          "counter": "reload_automations_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

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