Security audit

Code Refactoring

Security checks for vulnerabilities and agentic risk

Overview

This skill provides ordinary code-refactoring guidance and examples, with no hidden execution, credential access, persistence, or network behavior found.

This skill is reasonable to install for refactoring help. Expect it to recommend source-code edits, so use it on projects with tests when possible and review diffs before committing important changes.

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

Self-Modification

Finding

Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
