Security checks for vulnerabilities and agentic risk

Overview

This is a static Chinese book-recommendation skill for emotional support; it has locale and medical-care limitations but no hidden code, persistence, or data-access behavior.

Install this as a Chinese-language bibliotherapy-style recommendation aid, not as medical or mental-health treatment. In crisis, medical emergency, self-harm, or severe psychiatric distress, rely on local emergency services or qualified professionals; the listed hotlines are China-specific.

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

Findings (3)

Natural-Language Policy Violations

Medium

Confidence: 94% confidence
Finding: The entire skill file is written only in Chinese and presents crisis-handling instructions and hotline information specific to China, but it does not state that the skill is limited to Chinese-speaking users or China-based contexts. This can violate language/locale policy expectations because users are not given a language choice or an explicit opt-in to region-specific handling.

Missing User Warnings

Medium

Confidence: 95% confidence
Finding: This file provides book recommendations for anxiety, depression, grief, health problems, and other high-vulnerability situations, but it does not include any disclaimer that the material is not professional medical or mental health advice. It also lacks crisis escalation guidance for users with self-harm, suicidality, severe depression, or acute psychiatric or medical distress, which could lead vulnerable users to rely on a static reading list when urgent professional support is needed.

Natural-Language Policy Violations

Medium

Confidence: 93% confidence
Finding: This markdown file contains only Chinese-language instructions and examples, which effectively imposes a specific language on users or downstream skill behavior. The policy allows locale constraints only when they are explicitly offered as a user choice or clearly documented and justified, which is not present here.
