Social Video Resizer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Chinese-language guide for resizing social videos and does not show hidden data access, persistence, or unsafe automation.

Install this if you are comfortable using a Chinese-language workflow for social video resizing. Review generated ffmpeg commands before running them on important source files, and verify current platform upload limits in the platform backend before publishing.

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

Natural-Language Policy Violations

Medium

Confidence: 94% confidence
Finding: The manifest description is entirely in Chinese and presents the skill behavior in that language without indicating that language is selectable. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is explicitly justified.

Natural-Language Policy Violations

Medium

Confidence: 95% confidence
Finding: The entire guide is written in Chinese, including headings, instructions, and usage notes, with no indication that language choice is optional or that the skill is intended only for a Chinese-language context. Under the policy rule, forcing a specific language without user opt-in is a natural-language policy violation.

Low

Confidence: 95% confidence
Finding: This markdown file contains all user-facing instructions in Chinese, and there is no indication that users may choose another language or that the skill is intentionally limited to a Chinese-speaking audience. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.
