Unit Test Coverage Helper

Security checks for vulnerabilities and agentic risk

Overview

This is a low-risk unit-test workflow skill with somewhat broad activation wording but no hidden execution, credential access, persistence, or data exfiltration behavior.

Installers should know this skill may activate on broad testing or quality requests, so it may be noisier than a tightly scoped unit-test helper. Its behavior is otherwise ordinary for coding assistance: review generated tests and commands before applying them to your repository.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The trigger phrases are broad enough to match ordinary user requests such as 'help me' or 'I need a practical workflow,' which can cause this skill to activate outside its intended scope. In an agent system, overly broad routing can override more appropriate skills, leading to incorrect behavior, prompt-scope confusion, or unintended execution paths.

Vague Triggers

Medium
Category

Confidence
96% confidence
Finding

The trigger phrases are very broad and include generic testing and software terms, which can cause the skill to activate in contexts where the user did not explicitly request this workflow. Over-broad activation increases the chance of unintended tool/skill invocation, misrouting user requests, and allowing this skill to influence conversations outside its intended scope.

Vague Triggers

Confidence
95% confidence
Finding

The description and usage guidance are broad enough to match many ordinary software requests, which can cause this skill to activate outside its narrow intended scope. Over-broad activation increases the chance of prompt hijacking at the routing layer, incorrect tool selection, or irrelevant instructions being injected into unrelated coding tasks.

Vague Triggers

Category

Confidence
96% confidence
Finding

The trigger keywords are generic terms like 'software-and-data', 'testing', and 'quality', which overlap heavily with normal development conversations. In a multi-skill agent, this can make the skill fire too often, creating misrouting and unnecessary exposure of the skill's instructions in contexts where they do not belong.

Confidence

Finding

The skill description and activation criteria are broad enough to match many ordinary testing-related requests, which can cause the skill to be invoked outside its narrowly intended purpose. Over-broad routing is dangerous because it can override more appropriate skills, increase unintended data exposure to the wrong workflow, and produce irrelevant or lower-quality guidance.

Confidence
95% confidence
Finding

The keyword list contains vague, high-collision triggers such as broad testing and quality terms that are likely to match many unrelated conversations. In a skill-routing system, this can lead to accidental invocation, misrouting, and context capture by a skill that was not the best fit for the user’s request.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The default prompt is framed as a generic help trigger for broad testing-related requests, while the policy also allows implicit invocation. That combination can cause the skill to activate in many ordinary software conversations, increasing the chance of unintended routing, over-collection of context, or the skill influencing tasks outside a narrowly scoped user request.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The trigger sentence is so generic that ordinary user requests about unit tests or practical workflows may invoke this skill unintentionally. Overly broad activation increases the chance of prompt-routing mistakes, causing the agent to apply this skill outside its intended scope and potentially override more appropriate, safer, or more specialized handling.

Natural-Language Policy Violations

Confidence

Finding

The file advertises separate English and Chinese instruction and guide files, but the README does not explain how language is selected or whether the user can choose their preferred language. This can create a locale-handling ambiguity that may result in the skill forcing a language without explicit user opt-in.
