RISK

Why neuron_send_campaign_message is rated Medium

This tool creates and sends messages to real WhatsApp users, which is a write operation that modifies state (message delivery logs, contact interaction history). While reversible in principle, the impact is high because mass messaging can violate spam regulations, damage reputation, incur costs, and affect user relationships.

From the tool's definition Tool name contains 'send' and description states 'Send a campaign message to selected eligible contacts via WhatsApp', indicating creation/transmission of outbound messages with side effects (delivery to external users).
