Unit Test Coverage Helper

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only helper for unit test coverage work, with broad trigger wording but no hidden execution, persistence, credential use, or destructive behavior.

Installers should be aware that this skill may trigger for broad software-quality wording, so it is best used when the user specifically wants help adding unit tests or improving coverage in an existing codebase.

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

Vague Triggers

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The trigger sentence is broad enough to match ordinary user requests about testing or practical workflows, which can cause the skill to activate outside its intended scope. Over-broad activation increases the chance of prompt routing mistakes, irrelevant instruction injection into unrelated tasks, and user confusion about why this skill was selected.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The invocation guidance lists generic keywords and trigger phrases without meaningful scope boundaries, making the skill eligible for a wide range of common software-help queries. In an agentic environment, this can lead to inappropriate skill selection, unnecessary instruction precedence, and accidental suppression of more suitable or safer specialized skills.

Vague Triggers

Confidence
95% confidence
Finding

The trigger sentence is broad enough to match many ordinary requests about testing or practical workflows, which can cause the skill to activate outside its intended scope. Over-broad invocation increases the chance of prompt hijacking-by-routing, where this skill is selected for general software requests and influences behavior in contexts not specifically about unit-test coverage improvement.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The trigger phrases are broad, natural-language requests that can easily match ordinary user speech unrelated to explicitly invoking this skill. That can cause unintended auto-activation, leading the agent to route requests into this skill when the user did not mean to, increasing the chance of incorrect tool use or context leakage across workflows.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The manifest description uses broad activation language such as 'software-and-data' and generic requests for workflows, analysis, or implementation support. This can cause the skill to be invoked for common engineering requests outside its intended scope, creating prompt-routing confusion and increasing the chance that unrelated tasks receive testing-focused instructions or artifacts.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The trigger keywords include generic terms like 'testing', 'regression', and 'quality' without qualifiers. These high-frequency words are likely to match many unrelated user requests, leading to overbroad activation and unintended delegation to this skill.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The example trigger sentences are phrased so generally that they provide weak gating signals for invocation. In systems that learn or pattern-match from examples, vague examples broaden the activation surface and can make the skill fire on ordinary requests that only loosely resemble the intended unit-testing use case.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill description enables use for a wide set of common topics like software-and-data, testing, and regression without clear boundaries. In an agentic environment, this ambiguity increases the chance of misrouting general requests into this skill, which can override more appropriate skills or produce off-target outputs.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The trigger keywords are broad and overlap with ordinary software-development conversations, making accidental activation likely. This can cause the agent to invoke the skill in contexts where it is not the best fit, leading to irrelevant guidance, prompt-scope confusion, or unintended handling of user requests.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The default prompt uses broad, everyday-language terms like 'help me' plus common software topics, which can cause the skill to be invoked in situations beyond the author's intended scope. Because implicit invocation is enabled, this increases the chance of over-triggering on general development requests and unintentionally inserting the skill into unrelated workflows.

Vague Triggers

Category
Not specified by scanner
Confidence
90% confidence
Finding

The invocation examples are generic and do not define clear boundaries for when the skill should or should not be used. Ambiguous examples make accidental triggering more likely, which can misroute user requests and apply this skill's workflow in contexts where it is not appropriate.
