Threat Modeling Expert

Security checks for vulnerabilities and agentic risk

Overview

This is a narrow threat-modeling guidance skill with no executable code, persistence, credential use, or hidden data handling.

Install this if you want structured help with threat modeling. Provide only architecture details you are authorized to review, and avoid including sensitive system details unless your workspace has appropriate access controls.

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

Vague Triggers

Finding
The phrase 'Use PROACTIVELY for security architecture reviews, threat identification, or building secure-by-design systems' encourages broad, unsolicited activation based on loosely defined contexts. In an agent environment, this can cause the skill to trigger when not explicitly requested, leading to unnecessary processing of potentially sensitive architecture information or scope overreach.
