What submit_config_flow_step does on Ha Nexus Agent
AI agents invoke submit_config_flow_step 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.
Why submit_config_flow_step is rated High
This tool drives a configuration flow forward by submitting user input, triggering state changes in Home Assistant's configuration system. It's not purely a read operation, nor does it irreversibly delete data — it executes a step in a multi-stage setup/configuration process whose effects depend on the submitted arguments (e.g., credentials, device selection, integration settings).

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