Oil Price Monitor

Security checks for vulnerabilities and agentic risk

Overview

This fuel-price reminder skill is mostly coherent, but it asks for recurring monitoring and memory storage without clear user consent, limits, or an unsubscribe path.

Install only if you want a China domestic fuel-price reminder and are comfortable enabling recurring checks. Before using scheduled reminders, require explicit opt-in, choose a check frequency and end date, and make sure the memory entry and cron task can be reviewed and removed.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
83% confidence
Finding

The skill title, triggers, usage examples, and reply templates are all presented only in Chinese and implicitly assume a single language/locale. Under the policy, forcing a specific language without user opt-in or documented justification can be a natural-language policy violation.

Missing User Warnings

Medium
Category

Confidence
92% confidence
Finding

The description presents automatic monitoring and reminders as core behavior but does not warn that the skill may perform recurring checks or send user-impacting notifications. Lack of disclosure undermines informed consent and may surprise users with automated actions based on their prior interactions.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The trigger condition '用户询问油价' is broad enough that ordinary conversation about fuel prices could invoke the skill unexpectedly. Overbroad activation can cause unintended tool use, incorrect context switching, or surprising behavior for users, especially when combined with external search and reminder features.

Vague Triggers

Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill enables scheduled monitoring '调价窗口前 1-2 天自动监测' without clear user opt-in, duration limits, or scope restrictions. This can lead to persistent background actions and reminders that the user did not knowingly authorize, creating consent and operational safety issues.

Skill Enumeration

Confidence
80% confidence
Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

Referencing MEMORY.md to record that a user '关注油价' introduces persistence of user preference data without any privacy notice, retention policy, or consent language. Even seemingly low-sensitivity preference tracking can become problematic if users are unaware that their interests are being stored across sessions.
