Security checks for vulnerabilities and agentic risk

Overview

The skill is rated benign with medium confidence, but the review is incomplete: scanners report a mismatch between its advertised batch video downloads and stated exclusions, and several scripts could not be fully interpreted.

Before installing, consider whether the conflicting description matches what you need. The verdict is benign, but confidence is medium and the scan was partial: only 20 of 32 components were fully inspected, so some script behavior remains unassessed.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: env.

Medium
Category
MCP Least Privilege
Confidence
70% confidence
Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

The manifest promises local batch video downloads, but the skill explicitly excludes downloading videos.

Medium
Category
Excessive Agency
Confidence
99% confidence
Finding

SKILL.md L003 advertises one-click batch downloading to local storage. However, L130 states that the skill does not download videos, L152 excludes file-download requests, and L261 reiterates that video files are not downloaded. This is a substantive mismatch in the advertised capability, not an implementation detail of retrieving video metadata or playback URLs.

Timestamp formatting mandates Beijing time without user choice or a documented regional justification.

Low
Category
Output Handling
Confidence
86% confidence
Finding

The comments explicitly require fixed Beijing time and conversion of API creation timestamps to that timezone. Although the constraint is documented, no regional requirement justifies it and no user-selectable timezone is offered.
