Hacker News

Security checks for vulnerabilities and agentic risk

Overview

This skill provides public Hacker News search and browsing instructions using official/public APIs, with no hidden persistence, credentials, or local data access.

Installing this skill means the agent may query public Hacker News and Algolia endpoints with the search terms you ask it to use. Avoid putting private or sensitive information into HN search queries, but the artifact itself does not request credentials or local file access.

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
