SQL Migration Linter

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local SQL migration linter that reads user-selected SQL files and does not show hidden, destructive, network, credential, or persistence behavior.

Install only if you are comfortable with the linter reading SQL files under the paths you pass to it. Avoid pointing it at broad directories unless you intend all nested .sql files there to be inspected.

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

This code traverses directories recursively with rglob("*.sql") and reads each discovered file, which is a data-access operation on user files. While the CLI arguments imply linting SQL files, there is no explicit user-facing warning, print, or comment near the recursive scan to disclose that an entire directory tree may be read.
