Security checks for vulnerabilities and agentic risk

Overview

This skill is a Chinese tile-installation and renovation helper with a local cost calculator, and I found no hidden data access, persistence, network behavior, or destructive actions.

Install this if you want Chinese-language renovation and tile-masonry guidance plus local cost estimates. Be aware it may trigger on broad renovation terms, and its prices and construction standards should be treated as estimates to verify with local professionals or regulations.

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
  • 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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The trigger list is broad enough to match common renovation and household terms such as '防水', '地漏', '空鼓', and '找平', which can appear in loosely related conversations. This can cause the skill to activate outside its intended scope and override a more appropriate skill or inject domain-specific guidance and script-routing behavior when the user did not explicitly request tile-masonry help.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

This code file contains user-facing natural language in Chinese for its description, argument help text, and usage instructions, which effectively forces a specific language. Under the policy, locale or language restrictions should either offer user choice or be explicitly documented as justified and region-specific.

Confidence
90% confidence
Finding

This markdown file contains user-facing natural language content exclusively in Chinese, and there is no indication that users may choose another language or that the locale is intentionally limited. Under the policy rule for language or locale constraints, this can be considered a forced language choice without explicit opt-in.

Finding

The file title and all instructional content are presented only in Chinese, with no indication that language selection is optional or contextually limited. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.
