Security audit

Json Processor

Security checks for vulnerabilities and agentic risk

Overview

This is a simple JSON-processing skill that discloses its jq dependency and does not show hidden execution, data access, persistence, or unsafe behavior.

Review the jq package-manager install step before using it, especially on shared or locked-down machines. Also note that the documentation is primarily in Chinese and includes private-contact donation/custom-service language.

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
