Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only fact-checking skill whose behavior is disclosed and aligned with checking user-provided claims.

Installers should expect this skill to perform fact-checking and bias analysis, likely using web search for user-provided claims. It is mainly Chinese-language in presentation, so users who prefer another language may need to ask the agent to respond in that language.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

Automatically triggering on any pasted text that contains statistics, claims, or assertions is ambiguous because many harmless inputs fit that pattern, including routine summaries, emails, or drafts. In an agent setting, this ambiguity can misroute user requests, invoke external-search behavior unexpectedly, and expose pasted content to processing paths the user did not clearly request.

Natural-Language Policy Violations

Confidence
78% confidence
Finding

Most of the skill content, examples, and output format are written in Chinese, which effectively biases the skill toward a specific language experience. Because the file does not explicitly offer the user a language or locale choice, this may violate a language/locale policy requiring opt-in rather than silent defaulting.
