Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local self-critique workflow, with the main caution being to cap or disable the debate loop when you are done.

Before installing, confirm the target directory, review or translate the generated Turkish prompt files if needed, and keep max_iterations set to a reasonable number. Only add the heartbeat snippet if you actually want recurring agent self-critique, and set active to false when finished.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
Findings (2)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The script's echoed setup messages and embedded markdown instructions are written in Turkish throughout, which imposes a specific language on users. Under the policy, language constraints should either be optional for the user or clearly justified as region-specific; neither is present here.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill explicitly instructs the agent to alternate personas and continue critique loops 'until you stop them,' but it does not warn users that this can lead to effectively unbounded iterative execution if no stop condition is enforced. In an agent environment, this can waste tokens, time, and compute, and may cause the agent to get stuck in self-perpetuating debate behavior instead of completing the primary task.
