Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed WeChat article-generation helper with no evidence of hidden access, persistence, destructive behavior, or data exfiltration.

Install only if you want a Chinese/WeChat-focused writing helper. Be aware that the package declares requests and openai dependencies, so future or fuller versions may need network/API access for real AI generation, but the inspected version does not show hidden or unsafe behavior.

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

Findings (4)

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
89% confidence
Finding

The natural-language content of the skill is presented only in Chinese, and the file does not indicate that the skill is region-specific or that users can opt into this language. Under the stated policy, forcing a specific language without user choice can be a locale-policy violation.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

The skill name and description are explicitly tied to the Chinese/WeChat ecosystem, which suggests a locale-specific experience. Because the manifest does not indicate that users can choose language/locale or that the regional constraint is intentional and documented, this may violate language/locale policy requirements.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
89% confidence
Finding

This is a manifest file, so vague-trigger review applies. The description broadly advertises an 'AI WeChat public account article auto-generation tool' with 'one-click' article generation and optimization, but provides no specific activation phrases, scope limits, or exclusion conditions, which could make invocation matching overly broad in systems that rely on manifest descriptions.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The natural-language description and function docstring indicate the skill is specifically a WeChat public-account article generator written for Chinese output, with no indication that users can choose another language or locale. This creates a language/locale constraint without user opt-in, which matches the policy-violation category for natural-language restrictions.
