Work Productivity Skill Vetter Workflow Helper

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only workflow helper with no executable payload, but its automatic activation wording is broader than necessary.

Installers should be aware that the skill may activate too easily for generic security or GitHub-related requests. Prefer explicit invocation for skill-vetting tasks, and narrow the trigger keywords if maintaining this package.

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
97% confidence
Finding

The skill description is broad enough to match generic terms like 'security' and 'first', which can cause unintended activation for unrelated requests. In an agent routing context, overbroad triggers can misroute sensitive tasks, override more appropriate skills, and expose users to incorrect or incomplete workflows for security-relevant decisions.

Vague Triggers

High
Category
Not specified by scanner
Confidence
99% confidence
Finding

The keyword list includes common words such as 'security', 'first', 'before', 'github', and 'bug fix', which are too generic to safely identify this specialized workflow. This makes accidental invocation likely across many unrelated prompts, especially in environments where skill selection is automatic, leading to unreliable routing and potentially unsafe advice in contexts the skill was not designed to handle.

Vague Triggers

Confidence
98% confidence
Finding

The trigger keywords include very broad generic terms such as "security", "first", "before", and "github", which are likely to appear in many unrelated conversations. This can cause accidental invocation of the skill outside its intended context, leading to inappropriate workflow takeover, user confusion, and possible interference with more suitable skills or safety controls.

Vague Triggers

Category

Confidence
97% confidence
Finding

The trigger sentence is broad enough to match common user phrasing such as asking for practical help or workflow support, which can cause the skill to activate outside its intended scope. Overbroad activation increases the chance that a security- or vetting-branded skill intercepts unrelated conversations and steers behavior, creating misrouting and trust-boundary problems rather than direct code execution risk.

Vague Triggers

High
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger remains ambiguous because it uses vague language and truncated phrasing that does not clearly delimit when the skill should or should not run. In practice this can cause accidental invocation on unrelated requests, exposing users to incorrect workflow guidance and making routing behavior easier to manipulate through prompt wording.

Vague Triggers

Category

Confidence
97% confidence
Finding

The trigger phrases are broad and include common terms like 'security', 'first', 'github', and generic help wording, which can cause the skill to activate for unrelated user requests. In a security-oriented workflow helper, unintended invocation is risky because users may receive vetting or workflow guidance when they did not explicitly ask for this skill, increasing the chance of inappropriate actions, confusion, or over-collection of context.

Confidence
95% confidence
Finding

The trigger phrases are broad enough to match generic terms like "security," "first," "github," and "bug fix," which can cause the skill to activate in contexts far outside its intended scope. In an agentic system, this increases the risk of incorrect routing, accidental invocation, and overexposure of a workflow that may influence security-related decisions without sufficient user intent.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The example trigger sentences are malformed and do not clearly demonstrate the intended invocation boundary, so they fail to constrain usage and may reinforce overly broad matching behavior. Poor examples increase the chance that developers or routing systems interpret vague fragments as valid triggers, compounding accidental activation risk.

Vague Triggers

Category

Confidence
93% confidence
Finding

The skill description defines usage conditions too broadly, covering general requests for workflow, checklist, analysis, implementation support, and several common keywords without clear boundaries. In an agent-routing environment, this ambiguity increases the chance that the skill is selected for unrelated tasks, producing misleading outputs or bypassing more appropriate specialized skills.

Vague Triggers

Category

Confidence
93% confidence
Finding

The default prompt uses broad, everyday phrasing such as general requests for help, workflow, checklist, analysis, or implementation support, making the skill eligible for activation in many ambiguous situations. In combination with implicit invocation, this increases the risk of over-triggering, prompt hijacking of routing behavior, and accidental use in contexts where the user did not intend to engage this skill.

Vague Triggers

Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill enables implicit invocation while providing no narrowly defined activation constraints, which can cause the agent to invoke this skill in loosely related contexts without explicit user intent. Because the skill is framed around security, vetting, and workflow help, overbroad automatic routing could expose sensitive user context to the skill or cause unintended security-relevant actions and recommendations.

Natural-Language Policy Violations

Category

Confidence
81% confidence
Finding

The file descriptions state that the skill instructions and guides exist in English and Chinese variants, but do not indicate how the user's preferred language is selected or whether the user can choose. This can conflict with a language/locale policy if the skill defaults to a language without explicit user opt-in.

Natural-Language Policy Violations

Confidence
77% confidence
Finding

The file is a Chinese README, but key user-facing content is presented in English, including the main requirement description. This can amount to an implicit language constraint or inconsistent locale behavior without giving users an explicit language option or justification.
