Security checks for vulnerabilities and agentic risk

Overview

This is a principles-only engineering guidance skill with broad activation language, but it does not include scripts, network access, credential handling, persistence mechanisms, or hidden behavior.

Install this if you want the agent to consistently apply architecture and engineering-quality review habits during coding tasks. Be aware that it is broad and may influence many code changes or reviews, so users who want narrow, task-specific behavior may prefer to invoke it only when architecture guidance is desired.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The README says to invoke the skill when you need to 'Make changes to a codebase,' 'Design a new feature,' or 'Perform a code review,' which are very broad activities that overlap with many routine requests. It does not provide constraints, narrower trigger phrases, or negative examples to clarify when the skill should and should not activate.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill's invocation guidance is extremely broad: it says to use this skill whenever making code changes, designing features, or doing reviews, which covers a large fraction of engineering interactions. That can cause persistent instruction overreach, where the skill influences tasks beyond a narrowly scoped purpose and increases the chance of unnecessary policy shaping, workflow interference, or accidental precedence over more task-specific guidance.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The README says the skill is invoked automatically when the user makes changes to a codebase, designs a new feature, or performs a code review. These are broad, common activities without scope limits, exclusions, or negative examples, so the trigger conditions are ambiguous and likely to overlap with many ordinary interactions.

Scope Creep

Low
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
