Security checks for vulnerabilities and agentic risk

Overview

This skill coherently recommends a next book using limited relevant context and has no executable code, persistence, or hidden high-impact behavior.

Before installing, note that the skill may answer in Chinese by default and may use relevant long-term memory or reading-history tool data if available. Its own instructions limit that use and tell the agent not to expose unrelated memories or save new memory without explicit permission.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The response contract hard-codes Chinese output (e.g. '最推荐:《书名》— 作者') without any requirement to detect or honor the user's language preference. This can cause the skill to answer in an unexpected language, reducing usability and potentially leading users to misunderstand recommendation rationale, caveats, or uncertainty disclosures.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill metadata hard-codes Chinese in both the short description and default prompt, which can override or bias the agent's response language without an explicit user request. This can cause user-confusion, mismatched expectations, and prompt-level policy drift, especially in multilingual contexts where the user did not opt into Chinese output.
