Proposal Writer Pro

Security checks for vulnerabilities and agentic risk

Overview

This is a content-only sales proposal writing skill with no evidence of hidden execution, data access, persistence, or exfiltration behavior.

Before installing, treat it as a sales-writing aid: review generated claims, ROI figures, customer references, legal terms, and follow-up messages for accuracy and compliance with your organization's policies. No hidden technical authority was evident in the inspected artifacts.

A.I.G

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 90% confidence
Finding: The display name and description are written entirely in Chinese, presenting the skill as a Chinese-language assistant without indicating that users can choose another language. This can violate language/locale policy when a skill appears to impose a language preference absent explicit opt-in or justification.
