RISK

Why neuron_update_newsletter is rated Medium

The tool modifies existing newsletter metadata (name and description) in a WhatsApp Channel system. This is a Write operation because it creates or modifies data reversibly—the changes can be undone by updating the fields again.

From the tool's definition Tool name contains 'update' and description states 'Update the name or description of an existing WhatsApp Channel newsletter. Only provided fields are changed.' This is a reversible modification of data.
