Whois Checker

Security checks for vulnerabilities and agentic risk

Overview

This skill appears to be a low-risk plain-text reference helper, though its content is mostly generic rather than genuinely Whois-specific.

Install only if you are comfortable with a basic, mostly generic reference script. It does not appear to access secrets, call the network, or modify the system, but users expecting real Whois-specific operational guidance may find the content incomplete or misleading.

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

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

Medium
Category

Confidence
88% confidence
Finding

The description repeatedly uses generic phrases like 'Reference tool for devtools' and 'Quick lookup' without explaining when this skill should activate versus other general help or reference skills. It also does not provide negative examples or a narrow invocation context, which can make routing ambiguous in manifest/markdown-based skill selection.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The manifest says this skill is a reference tool for 'Whois Checker concepts, best practices, and implementation patterns.' However, every command emits broad templated devtools text with vague phrases like 'specialized tool/concept' rather than concrete WHOIS-checker-specific reference content. This creates a semantic mismatch between the claimed subject-matter behavior and the actual code output.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The top-of-file comment asserts a specific intent: a reference tool for Whois Checker in devtools contexts. But the implemented command handlers output mostly boilerplate guidance applicable to almost any tool, without meaningful Whois Checker-specific documentation. That makes the documentation actively misleading about what the script provides.
