Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese divination instruction skill with off-platform promotional contact information, but it has no code, data access, persistence, or privileged behavior.

Install only if you are comfortable with a Chinese-language divination prompt. Avoid sharing sensitive personal, financial, or legal details in divination questions, and treat the WeChat contact and external marketplace link as off-platform promotion outside ClawHub safeguards.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The example trigger phrase is broad enough that ordinary user conversation about emotions or recent relationships could unintentionally activate or invoke the skill. In an agent ecosystem, this can cause unexpected handling of sensitive personal topics, misrouting of user intent, or silent invocation of a divination workflow when the user did not explicitly request it.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill’s user-facing instructions and examples are entirely in Chinese, and there is no indication that language choice is optional or that the skill is intentionally limited to Chinese-speaking users. Under the policy, forcing a specific language without user opt-in can be a natural-language policy concern.

Context-Inappropriate Capability

Low
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill documentation includes unrelated contact details, WeChat promotion, and marketing for other tools that are not necessary for a divination skill to function. This creates a trust and social-engineering risk by encouraging users to leave the platform and contact the author through external channels, where phishing, data harvesting, or off-platform monetization could occur without platform safeguards.
