Offer Comparison

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward job-offer compensation comparison guide with no hidden code, persistence, credential use, or unrelated data access.

Before installing, expect to provide sensitive compensation details and review any assumptions used for private equity discounts or stay horizon. The packaged skill does not include the referenced helper script, so programmatic output may require a separate local script or manual calculation.

A.I.G

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
The description says to use the skill when asked to 'compare job offers' or 'which offer pays more over time,' which are broad phrases that could overlap with ordinary conversation. The file does not provide negative examples or tighter constraints on when the skill should not activate, increasing the risk of unintended invocation.
