Text Transform

Security checks for vulnerabilities and agentic risk

Overview

This skill sends text to a disclosed external text-processing service, with clear instructions to ask before sending user-provided or private content.

Install only if you are comfortable sending selected text to text.agentutil.net. Do not use it on private files, messages, secrets, or regulated data unless you intentionally approve that text being processed by the external service.

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
