Tvs Analyze

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward code-analysis helper with an optional dependency-graph command, and I found no hidden, destructive, exfiltrating, or persistent behavior.

Before installing, understand that this skill is optimized for Chinese-language explanations and may suggest running a local Node script to generate dependency graphs. Only run that command in a trusted project after checking the referenced script, but the inspected package itself contains only markdown instructions.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • 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
Findings (2)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The instruction says all text, node names, and arrow labels in diagrams '必须用中文', which imposes a specific language regardless of the user's preference. This is a natural-language policy issue because the skill does not offer a language choice or document a justified locale restriction.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The skill explicitly instructs invoking a local shell command to run a Node.js script, which expands the skill from passive code explanation into operational command execution. In an agent setting, this creates a real risk that untrusted repositories or manipulated environments could cause the agent to execute unintended code or normalize unnecessary tool use during analysis.
