## Why add_grid_consumption is rated Medium

This tool creates or modifies energy dashboard settings (write operation) rather than reading data, executing arbitrary commands, or destroying data. The severity is medium because misconfiguration of energy monitoring flows could cause incorrect energy reporting but does not directly compromise security or enable destructive actions.

From the tool's own definition: "The tool 'add_grid_consumption' creates or modifies the Energy Dashboard's grid source configuration by adding a 'flow_from' entry. This is a state-mutating operation that updates dashboard configuration."

## Use case

AI agents use add_grid_consumption to create or update resources in Ha Nexus Agent, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ha Nexus Agent environment.
