Security checks for vulnerabilities and agentic risk

Overview

This skill is a local EU AI Act compliance navigator, with no evidence of hidden access, persistence, exfiltration, or destructive behavior.

Install only if you are comfortable with a simple local compliance aid that is not legal advice. Expect Chinese-first CLI output and verify EU AI Act conclusions against official or legal sources before relying on 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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • 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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The file presents the skill's operational description and agent instructions entirely in Chinese, including triggers and rules of engagement. Under the stated policy, forcing a specific language without user opt-in can be a natural-language policy violation, and this file does not provide an alternative language option or explain a required Chinese-only scope.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

This markdown file includes policy-relevant instructions and licensing text primarily in Chinese, including imperative language such as '务必并读' and a required disclosure block, without stating that users may choose their preferred language. Under the language/locale policy rule, forcing a specific language without opt-in is a natural-language policy violation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The file presents the primary display name and core description in Chinese, and the usage conditions are also written in Chinese. This can impose a specific language/locale on users without any explicit opt-in or language-selection mechanism, which matches the policy category for language/locale constraints.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The module docstring, CLI help text, and output strings are primarily in Chinese, and the skill does not state that language selection is optional or configurable. This can violate a language/locale policy when users are forced into a specific language without opt-in.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
78% confidence
Finding

The interface metadata declares a specific entry point at scripts/eu_ai_act_nav.py (L036), while the English usage text says it runs the Python logic in eu_ai_act_nav.py (L072) and the Chinese section similarly references eu_ai_act_nav.py (L092). This is a documentation-to-implementation inconsistency, though minor and not clearly security-impacting.
