Security audit

Responsive Tester

Security checks for vulnerabilities and agentic risk

Overview

This skill only prints local reference text and does not access credentials or the network, though its content is generic and has minor documentation inaccuracies.

Install only if you want a simple local reference scaffold. It appears low risk from a security standpoint, but users should expect generic documentation and a minor command-name inconsistency rather than a complete responsive testing tool.

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

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.

Description-Behavior Mismatch

Medium
Category

Confidence
95% confidence
Finding

The manifest claims this skill is a quick lookup/reference tool for Responsive Tester concepts, best practices, and implementation patterns. However, the script only prints broad, placeholder-style devtools guidance with generic sections like networking, migration, and security, and does not implement content clearly specific to responsive testing; this indicates the advertised subject matter does not match the actual delivered behavior.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
98% confidence
Finding

The inline cheatsheet presents 'troubleshooting' as an essential command, but the command dispatcher does not define or route any such command. This is an active contradiction between the skill's own documentation and executable behavior, likely to mislead users about available functionality.
