AgentMailer Inbox

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed AgentMailer inbox-management integration with expected external service access and user-control safeguards for creation and deletion.

Install only if you intend to let your agent manage AgentMailer inbox identities. Review the connected AgentMailer account permissions, because the skill can create and update inboxes and can deactivate an exact inbox after confirmation.
