RISK

Why neuron_send_contact_card is rated Medium

This tool sends (creates and transmits) a vCard contact card message through WhatsApp. It modifies the messaging state by adding a new message to a conversation, which is reversible (messages can be deleted). This qualifies as Write rather than Execute because it performs a specific, bounded action (sending a formatted card) rather than arbitrary code execution.

From the tool's definition Tool name 'neuron_send_contact_card' and description 'Send a vCard contact card via WhatsApp with name, phone, and optional organization' indicates creation/transmission of a contact card message.
