Security checks for vulnerabilities and agentic risk

Overview

The skill is a broad automation/agent skill with read, write, and command execution authority, but its scope and safety claims are too vague for that level of access.

Review this skill carefully before installing. It asks for broad file and command execution tools and should only be used in a constrained workspace where you are comfortable with file changes and command execution. Do not rely on its sandbox, whitelist, encryption, or permission-control claims unless the host platform separately enforces them.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The description says to use the skill whenever AI model calling, intelligent dialogue, agent orchestration, or LLM applications are needed, which covers a very wide range of common AI tasks. It does not provide specific trigger phrases, scope boundaries, or negative examples beyond one narrow exclusion, so it could overlap with many unrelated skills and cause unintended invocation.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill advertises that command execution occurs in a safe sandbox and under whitelist restrictions, but the manifest exposes broad exec capability and the markdown provides no enforceable constraints or implementation details. This can mislead users and host agents into trusting potentially dangerous command execution behavior that may have full system impact.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill describes file handling, API integration, and command execution capabilities without a prominent up-front warning that these actions can modify the filesystem, invoke external services, or affect the local environment. In a skill with read/write/exec tools, weak disclosure increases the risk of unsafe invocation and unintended system or data impact.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
81% confidence
Finding

The display name, summary, and primary description are presented in Chinese, with no statement that users may choose their preferred language. For a general-purpose agent skill, this can amount to a locale/language policy issue unless the language restriction is explicit and justified.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The documentation claims encrypted communication and permission controls for protecting data, but the skill definition contains no evidence of these controls or any mechanism that would guarantee them. Unsupported security assurances create a false sense of safety and may cause users to expose sensitive data under incorrect assumptions.
