Sleep Quality Improver

Security checks for vulnerabilities and agentic risk

Overview

This sleep-wellness skill is coherent and non-executable, with a language-localization safety note but no evidence of malicious or overbroad behavior.

Reasonable to install for general sleep-habit coaching. Users should treat it as wellness guidance only, seek medical help for persistent or severe sleep problems, and be aware that some crisis/disclaimer wording and examples are Chinese-localized rather than clearly language-adaptive.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill hard-codes crisis escalation and disclaimer content in Chinese without indicating that the response should match the user's language or offer alternatives. In a safety-critical moment, users who do not read Chinese may not understand self-harm escalation instructions, which can delay access to urgent help and undermine the model's duty of care.

Natural-Language Policy Violations

Low
Category

Confidence
90% confidence
Finding

The skill description includes substantial user-facing example content in Chinese, but the README does not state that the skill is Chinese-language only or offer users a language/locale choice. Under the policy rule, forcing or implicitly assuming a specific language without opt-in can be a natural-language policy issue.
