Security audit

tone-adjuster

Security checks for vulnerabilities and agentic risk

Overview

This is a simple tone-rewriting skill with no executable code, persistence, credential access, or hidden authority.

Installers should understand this skill may activate on common rephrasing requests and will output five versions of the user’s message. Avoid giving it sensitive text unless you are comfortable having that text processed by your agent environment.

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

Confidence

Finding

The listed trigger phrases are very broad, natural-language expressions that commonly appear in ordinary conversation, so the skill may activate when the user did not explicitly intend to invoke it. In an agent environment, unintended activation can cause the assistant to prioritize tone rewriting over the user's actual request, leading to confusing behavior or accidental transformation of sensitive workplace/customer communications.

Natural-Language Policy Violations

Low
Category

Confidence
84% confidence
Finding

All user-facing instructions, triggers, and examples in the file are Chinese-only, and the document does not state that the skill is intentionally limited to Chinese users or offer an opt-in language choice. This may violate language/locale policy when a skill implicitly forces a specific language without user selection.
