Yq Hot Topic Tracker

Security checks for vulnerabilities and agentic risk

Overview

This skill mostly matches a hot-topic research and article-writing purpose, but its scheduled reuse of the last tracked topic and automatic file editing need review before use.

Install only if you want a Chinese-oriented hot-topic tracker that searches the web and creates local article files. Before using scheduled tracking, confirm how the previous topic is remembered and make sure generated files are written to a safe location where overwrites will not matter.

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
  • 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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The description is written as a Chinese-only content-generation skill and frames the output style around Chinese new-media writing conventions, but it does not state that language choice is optional or user-configurable. Under the policy, forcing a specific language or locale without opt-in is a natural-language policy concern.

Missing User Warnings

Category

Confidence
89% confidence
Finding

The skill directs the agent to save output files and later convert them, but it does not warn the user that files will be created or potentially overwritten. Silent file creation/modification can surprise users, overwrite prior work if names collide, or leave artifacts in shared environments without informed consent.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The fact-checking step instructs the agent to revise the previously written article file in place if issues are found, again without requiring user awareness or approval for that modification. In-place editing can destroy the original draft, obscure what changed, and modify user-visible artifacts unexpectedly.

Context-Inappropriate Capability

Low
Category
Not specified by scanner
Confidence
86% confidence
Finding

The scheduled-task section says the skill may automatically continue using the 'last tracked topic' in timed scenarios, which introduces implicit state reuse beyond the primary user-input-driven workflow. That can cause the agent to act on prior user context without an explicit fresh prompt, creating privacy and consent issues if the remembered topic is sensitive or belongs to a different session/user.
