Security checks for vulnerabilities and agentic risk

Overview

This skill is a lightweight workflow prompt for keeping agents aligned, with one disclosed but potentially surprising workspace note update.

Install only if you want a Chinese-language workflow prompt for keeping agent work aligned. Before using it, decide whether agents may update HEARTBEAT.md automatically; otherwise, require them to show the proposed status text and wait for your approval before writing the file.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • 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
Findings (2)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The description and all operative instructions are written entirely in Chinese, which effectively constrains use to a specific language without any opt-in or alternative language path. Under the policy, language restrictions should either be optional for the user or clearly justified as region-specific.

Missing User Warnings

Confidence
95% confidence
Finding

The skill instructs the agent to update HEARTBEAT.md on session exit without any warning, consent check, or scope restriction for modifying files in the user's workspace. This can lead to unauthorized or unexpected file writes, which is risky in agent environments where documentation instructions may directly influence tool use and persistence.
