WHAT IT DOES

WHY IT NEEDS A POLICY

Why create-contact-import needs a policy

This tool creates or uploads contact data in bulk, which is a reversible write operation. While it modifies the system state (adds contacts), it does not delete data irreversibly or move money, placing it in the Write category. Severity is high because bulk contact imports could be used to pollute a contact database or enable spam/phishing campaigns if the AI agent is compromised or misaligned.

From the tool's definition Tool name 'create-contact-import' and description 'Bulk import contacts' indicate creation of contact records in bulk. This is a write operation that creates/modifies data in the Mailtrap system.
