WHAT IT DOES

What reload_helpers does on Ha Nexus Agent

AI agents invoke reload_helpers 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_helpers is rated High

Reloading helper entities triggers a system operation that re-processes configuration and restarts entity states. This is an Execute-level action as it runs an operational process with side effects (entity states may change, automations may be affected), but it is not directly destructive or financial. Misuse could cause temporary disruption to smart home automations and helper entities.

RECOMMENDED RULE

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

reload_helpers Rate-limited

reload_helpers 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.

    "reload_helpers": {
      "limits": [
        {
          "counter": "reload_helpers_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_helpers call is checked against it from then on.
