Burst Sms

Security checks across malware telemetry and agentic risk

Overview

This Burst SMS skill is coherent, but it gives an agent broad ability to send messages and change contact lists without clear confirmation safeguards.

Review before installing on any production Burst SMS account. Use only with explicit approval for every send, deletion, opt-out, bulk edit, cancellation, or raw proxy request, and verify recipients, message content, affected lists, cost, and compliance impact before execution.

Vague Triggers

Medium

Confidence: 88% confidence
Finding: The skill description is broad enough to match many generic requests involving SMS data, records, or workflows, which can cause an agent to invoke it in situations where user intent is ambiguous. Because this skill exposes both read and high-impact write operations, overbroad routing increases the chance of unintended outbound messaging or modification of contact/list data.

Missing User Warnings

Medium

Confidence: 94% confidence
Finding: The documentation advertises capabilities such as sending SMS, deleting lists, removing contacts, and opting out contacts without any warning that these are externally visible or destructive actions. In an agentic context, that omission can lead to accidental mass messaging, data loss, or irreversible customer-impacting changes if the model treats these actions as routine operations.
