MySQL to PostgreSQL Migration

Security checks for vulnerabilities and agentic risk

Overview

This is a static MySQL-to-PostgreSQL migration guide with no executable code or hidden privileged behavior.

Install this only if you are comfortable using a Chinese-language migration reference. Review suggested SQL replacements and sequence creation against your schema before applying them, because database migration changes can affect production data even when the skill itself is only guidance.

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

Finding

The skill title and the main instructional content are presented in Chinese, with no indication that the user can choose another language or that the skill is intentionally limited to a Chinese-speaking audience. This creates a natural-language locale policy issue because it effectively imposes a language preference without opt-in.
