Security audit

Fable Explainer

Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-only teaching skill for explaining concepts with stories, with no evidence of hidden execution, data access, persistence, or destructive behavior.

This skill is safe to treat as a storytelling explanation prompt. Before installing the optional knowledge-rag companion, review that separate package and its publisher because it is referenced by name without a pinned version or digest. Expect the skill to answer primarily in Chinese and to favor fables or analogies for some broad learning requests.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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

Finding

The metadata description is written entirely in Chinese and presents the skill behavior in Chinese without any indication that the language should follow the user's preference. In multilingual environments, this can lead to unsolicited language switching, degraded usability, and misrouting or confusion if the system assumes the skill should answer in Chinese regardless of the user's language.

Vague Triggers

Medium

Confidence

Finding

The trigger examples are broad enough to match ordinary conversational requests like '帮我想想这个' or '给我讲讲这个概念', which can cause the skill to activate when the user did not explicitly ask for this teaching style. In a skill-routing environment, that overbroad activation can override user intent, interfere with other skills, and unexpectedly reshape responses into stories or analogies.
