Rtk Token Saver

Security checks for vulnerabilities and agentic risk

Overview

The skill is a transparent developer-tool workflow for reducing noisy command output, with no bundled executable code or hidden install behavior.

Before using this skill, make sure the local rtk CLI itself is a trusted tool, especially before wrapping commands that may involve credentials or high-impact systems. Use native commands when exact output is needed or when handling secrets.

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

Unvalidated Output Injection

High

Category: Output Handling
Confidence: 80% confidence
Finding: Model output is used without validation or sanitization. Unvalidated output injected into downstream contexts (SQL, shell, HTML) enables injection attacks and arbitrary code execution.
