## Why neuron_send_sticker is rated Medium

This tool sends a sticker message via WhatsApp, which is a write/communication action. It creates an outbound message but does not delete data, execute code, or involve financial transactions. Misuse potential is low—at worst it could send unwanted sticker messages to contacts.

From the tool's own definition: "Send a WebP sticker image via WhatsApp"

## Use case
