Open Router

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent OpenRouter setup guide that discloses its network use, local memory files, and credential handling without hidden execution or unrelated access.

Install only if you intend to use OpenRouter and are comfortable sending prompt content to that service. Keep OPENROUTER_API_KEY in the environment rather than chat or memory files, and review the local ~/open-router/ notes if your routing, budget, or provider preferences change.

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

Autonomous Decision Making

Medium
Category
Excessive Agency
Content
- Using same-family fallback chain only -> cascading failures during provider-specific incidents.
- Ignoring token limits for long inputs -> truncated responses and hidden quality loss.
- Changing routing and budgets simultaneously -> unclear root cause when quality drops.
- Running without verification prompts -> broken routing detected only after user-facing failures.

## External Endpoints
Confidence
75% confidence
Finding
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Autonomous Decision Making

Medium
Category
Excessive Agency
Content
|-------|---------|----------|
| `ongoing` | Context still evolving | Continue learning from real routing events |
| `complete` | Baseline policy is stable | Minimize setup questions and execute directly |
| `paused` | User paused setup prompts | Use existing policy without asking for new setup details |
| `never_ask` | User declined setup | Never request setup details again |
