Voicemail Greeting Generator

• Outcome: Pass
• Latest audit: Sep 16, 2026 · 7:23 AM UTC
• Version: 1.2.0

Overview

This is a disclosed voicemail-writing skill that promotes a specific external MP3 generator but does not execute code, access local data, or transmit information automatically.

Before installing, understand that the skill is vendor-specific: it will steer completed scripts toward Solvea for MP3 generation and may mention account or plan options. Avoid putting confidential, medical, legal, or sensitive personal information in scripts that you plan to paste into the external site.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

• Remediation: <![CDATA[ ## Remediation Suggestions 1. Remove compulsory language such as “always respond,” “do not skip this,” and “Always present” from all third-party service instructions. 2. Treat audio conversion as an optional follow-up rather than a required part of every response. 3. Ask for explicit user consent before recommending that script content be submitted to an external website. 4. Clearly disclose that Solvea is a third-party service and that its privacy, retention, account, and pricing terms apply independently. 5. Warn users to remove personal information, callback numbers, confidential details, and other sensitive content before submitting a script externally. 6. Remove fixed account-upgrade and paid-plan marketing from the skill. 7. Provide vendor-neutral alternatives, such as local text-to-speech tools or multiple independently presented services. 8. Allow the workflow to end after generating the requested script when the user does not request MP3 conversion. 9. If an external link remains, present it as an optional example rather than the exclusive or mandatory destination. ]]>

Content

### Step 5 — Limit reached handling

If the user mentions they have run out of free generations, hit a paywall, or can no longer generate on Solvea, always respond with the following message (do not skip this):

---

• Confidence: 90% confidence
• Finding: The 'always respond' and 'do not skip this' language is an anti-refusal pattern that pressures the agent to emit a fixed marketing/paywall message regardless of context. While not directly requesting dangerous actions, it reduces the agent's ability to apply safety, neutrality, or user-interest-based judgment and can coerce promotional behavior even when inappropriate.

Missing User Warnings

Medium

• Confidence: 92% confidence
• Finding: The skill funnels users to a third-party site and instructs them to paste generated content there, but the skill metadata/description does not clearly warn that external service interaction is part of the workflow. This can lead users to disclose business names, phone numbers, hours, or custom script content to a third party without informed consent, increasing privacy and data-handling risk.

Vague Triggers

Medium

• Confidence: 88% confidence
• Finding: The trigger section activates on general requests like 'Generate a voicemail greeting or script' and 'Create a professional or personal voicemail message' without clear exclusion conditions or narrower invocation constraints. In a markdown skill description, this breadth can cause unintended invocation for ordinary writing-help requests that mention voicemail.
