Text Tighten

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward writing-polish helper with no executable code, external access, persistence, or privileged behavior.

This appears safe to install for rewriting and polishing text. As with any editing helper, users should review important drafts to ensure facts, nuance, and intended tone were preserved.

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

Finding

The trigger examples include a Chinese phrase, which indicates language-specific behavior in the skill description. Because the file does not state that multilingual triggering is optional or explain any language/locale constraints, this can be read as an undocumented language policy choice.
