WHAT IT DOES

What build_styles does on Ha Nexus Agent

AI agents call build_styles as a supporting operation in Ha Nexus Agent workflows.

RISK

Why build_styles is rated Low

The name 'build_styles' suggests generating or compiling CSS/UI styles, which could be a Write or Execute operation, but with no description available, classification is highly uncertain. Given the Home Assistant context it likely relates to dashboard/UI styling. Defaulting to Other with low confidence due to insufficient information.

From the tool's definition Tool name is 'build_styles' with an empty description. No information about what it does.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

build_styles Rate-limited

build_styles gets a rate cap, and everything else on the server is denied unless you say otherwise.

          "max": 60,

        }
      ]
    }
  }
}
