RISK

Why contacts_add_channel is rated Medium

This is a Write operation because it creates new associations and modifies existing contact records by adding channel information. Severity is medium because unauthorized misuse could compromise contact information integrity and create false associations between identities, but it's reversible and doesn't involve financial transactions or irreversible destruction.

From the tool's definition Tool performs 'Link a new channel identity' which creates or modifies contact records by adding email, phone, LinkedIn, or other channel identifiers to existing contacts. This is reversible data modification, not retrieval or deletion.
