Security checks for vulnerabilities and agentic risk

Overview

This skill mainly provides bid-writing help, but it also steers users to a specific external commercial site and QR-code community in a way that is not clearly optional or disclosed up front.

Review this skill before installing if you do not want bid-related answers to include a specific third-party service link or enterprise-WeChat QR invitation. It does not appear to run code or access local data, but its responses may promote an external service unless the instructions are narrowed.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The trigger condition activates on broadly defined bid-related conversation, which can cause the skill to engage in ordinary chats without clear user intent to invoke this specialized workflow. In context, that increases the chance of unsolicited promotion and external redirection, making the skill easier to abuse for traffic steering or inappropriate takeover of general conversations.

Missing User Warnings

Confidence
95% confidence
Finding

The skill explicitly instructs the agent to send users to a third-party website and a group QR code, but provides no warning that the user is leaving the assistant context or interacting with external services. In this skill's context, the redirection is central to the workflow rather than incidental, which makes the risk more significant because ordinary informational requests can be converted into off-platform funneling.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The instruction '全程使用中文' forces a specific language for all interactions, but the file does not indicate that this is optional, user-selected, or required by a clearly documented regional compliance context. This is a natural-language policy concern because it removes language choice without opt-in.
