Math Screenshot To Giscus

Security checks for vulnerabilities and agentic risk

Overview

This skill is a focused Markdown conversion helper for Chinese math content, with only low-impact local file output guidance and no hidden execution or persistence.

Installers should treat this as a specialized Chinese math-to-giscus formatting helper. Before using file delivery, confirm the output path and avoid overwriting existing files; use any GitHub rendering checks only on content and repositories you control.

A.I.G

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

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The skill explicitly recommends writing converted content to a local file via write_file(...) and frames it as the preferred delivery path, but it does not require user confirmation, warn about file creation/overwrite, or constrain the destination to a safe temp/output path. In an agent setting, this can lead to unintended local file creation or overwriting if the working directory or filename is influenced by context or user input.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
85% confidence
Finding

The description specifies handling of mathematical textbook screenshots or text in Chinese and the entire skill guidance is written as if the workflow is fixed to Chinese-language content. There is no indication that users may choose another language or that the Chinese-only scope is a documented regional/compliance constraint.
