Security audit

Nutrition Label

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple local reference document/script with no evidence of credential access, network activity, persistence, or destructive behavior.

Before installing, consider whether the generic command names could interfere with other skills in your agent environment. From the inspected artifacts, the security risk is low because the skill only prints static reference text and does not access files, credentials, the network, or persistent settings.

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
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • 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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Vague Triggers

Category

Confidence
92% confidence
Finding

The skill description and command names are very broad, using generic terms like 'intro', 'quickstart', 'patterns', and 'security' without strong namespacing. In agent environments that auto-select skills from natural-language prompts, this can cause accidental invocation for unrelated requests, leading to prompt routing confusion, unexpected tool output, or interference with safer/more appropriate skills.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The command trigger set is underspecified and composed of highly common words that are likely to appear in ordinary user requests. Even though the skill is read-only and declares no network or credential use, ambiguous triggers can still make the agent invoke this skill unexpectedly, creating incorrect behavior, response contamination, or denial of access to the intended tool path.
