System Architecture Engine

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only system architecture guidance skill with no executable code, persistence, credential handling, or hidden runtime behavior found.

Install only if you want your agent to provide broad system architecture advice. Treat generated architecture templates as guidance to review before applying to real systems, especially examples involving payment, shipment, or reservation APIs.

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

Tool Parameter Abuse

High
Category
Tool Misuse
Content
- name: "Reserve Inventory"
      service: "inventory-service"
      action: "POST /reservations"
      compensation: "DELETE /reservations/{id}"
      timeout: "5s"
      retries: 2
Confidence
80% confidence
Finding
Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Vague Triggers

Medium
Confidence
92% confidence
Finding
The README tells users to invoke the skill with generic phrases like "Review my current architecture" and "Help me choose between microservices and a modular monolith." These are broad natural-language requests without clear trigger boundaries or exclusion conditions, which could cause unintended invocation in normal architectural discussions.
