Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward local article formatter that reads a user-provided Markdown file and writes derived platform-specific Markdown outputs, with no hidden network, credential, persistence, or destructive behavior found.

Install only if you are comfortable with a local tool reading the article file you provide and writing generated Markdown files into the chosen output directory. Use a dedicated output folder if you want to avoid overwriting similarly named files.

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

MCP Least Privilege
Confidence
82% confidence
Finding
The skill appears to perform file-based transformations and the static analysis detected file read/write capabilities, but the manifest does not declare any explicit tool scope such as permissions or allowed-tools. This creates an overbroad trust boundary: a host may permit filesystem access implicitly or users may be unable to review the skill's required capabilities, increasing the risk of unintended file access or overwrite if the implementation is later added or changed.

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
This code uses Chinese-only natural-language strings for the program description, argument help, errors, and success output. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale restriction is explicitly justified, which is not present here.

Natural-Language Policy Violations

Low
Confidence
96% confidence
Finding
This shell script presents all user-facing messages in Chinese, including installation status, usage, and documentation instructions. Because the file provides no language selection, opt-in, or justification for a locale-specific constraint, it violates the language/locale policy criteria.
