Security checks for vulnerabilities and agentic risk

Overview

This HR skill is mostly coherent, but it combines broad activation triggers with write, network, session, and subagent authority for high-impact agent lifecycle actions.

Review this skill before installing in any environment where agents can modify records, sync private knowledge bases, send session messages, spawn subagents, or delete model/data assets. Use it only with explicit approval gates for retirement, deletion, permission assignment, and external API actions, and consider narrowing its activation triggers.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The trigger list is broad, multilingual, and includes generic terms like "HR," "ethics," and lifecycle-related phrases, which can cause the skill to activate in contexts where the user did not intend to invoke it. Because the skill has write, network, and subagent/session permissions, unintended activation can lead to downstream sensitive actions or data handling beyond user expectations.

Missing User Warnings

Medium
Category

Confidence
95% confidence
Finding

The skill advertises HR lifecycle actions including onboarding, assessment, and retirement, while the manifest grants file write and network/API permissions, yet the description does not clearly warn users about these capabilities or the possibility of destructive retirement-related operations. In an HR/governance context, hidden state-changing behavior is especially risky because it may modify records, propagate decisions externally, or initiate deletion/retirement workflows without informed consent.

Natural-Language Policy Violations

Low
Category

Confidence
74% confidence
Finding

The skill content and interface descriptions are presented in a mixed Chinese-English format, and trigger phrases are defined in specific languages without stating whether users may interact in other languages or choose a preferred locale. This can amount to an implicit language policy constraint that is not documented as optional or justified.
