Singapore Location Helper

Security checks for vulnerabilities and agentic risk

Overview

This is a Markdown-only Singapore housing-location guide with no executable behavior or hidden system access.

Installers should know the skill is written for Chinese-speaking users and its rental/transport figures should be independently checked because market data changes, but it does not appear to ask for sensitive permissions or perform actions on its own.

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

Not specified by scanner
Confidence
87% confidence
Finding

The README presents all user-facing descriptions, examples, and usage guidance exclusively in Chinese. Under the policy rule for language or locale constraints, this can be a natural-language policy violation because the skill appears to force a specific language without documenting user choice or opt-in.

Natural-Language Policy Violations

Confidence
95% confidence
Finding

The manifest description is entirely in Chinese, which imposes a specific language on users without any indication that other languages are supported. The policy requires flagging language or locale constraints when the skill does not offer user opt-in or a documented justification.

Confidence

Finding

The README content and usage guidance are presented in Chinese throughout, with no option for the user to choose another language. This is a natural-language policy concern because the skill appears to require a specific language rather than offering a user-selected locale.
