Security checks for vulnerabilities and agentic risk

Overview

This skill is a small local debate-loop helper that is visible and purpose-aligned, with some setup usability cautions but no evidence of malicious behavior.

Install into a dedicated directory, review the generated Turkish prompts before using them, and set max_iterations to a small value before adding the heartbeat snippet so the self-critique loop cannot consume more agent time than intended.

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

Vague Triggers

Finding

The skill defines the personas as taking turns critiquing each other 'until you stop them,' which leaves loop termination dependent on an external actor rather than a clear bounded condition. In an autonomous or semi-autonomous agent environment, this can cause unbounded iteration, wasted resources, and failure to converge or hand control back safely, especially since the skill also encourages stateful turn-switching and continued execution.

Natural-Language Policy Violations

Finding

The script's natural-language output and embedded prompt content are written in Turkish throughout, including setup messages and role instructions. This imposes a specific language on users without any opt-in, language selection, or documented reason that the skill is region-specific.
