Perf Analyzer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple Perf Analyzer reference helper that outputs static documentation and does not show credential access, network access, persistence, or hidden behavior.

Installing this appears low risk. Expect a command-style reference helper that prints Perf Analyzer guidance; review the publisher and source if provenance matters, and be aware that its activation wording is broad enough that it may be invoked for general perf/devtools questions.

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

Finding

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

Finding

The description says the skill is a "Reference tool for devtools" and offers "quick lookup" for concepts and patterns, but it does not explain when this skill should activate versus other general help or reference skills. Because this is a markdown skill file, the lack of explicit trigger scope or exclusion conditions makes invocation boundaries somewhat ambiguous.
