Security checks for vulnerabilities and agentic risk

Overview

The skill fetches public trending topics as described, without accessing credentials, uploading private files, or running background services.

No cloud account or credentials are needed. Public providers receive ordinary network requests; use --offline to avoid them. Live provider content was not verified, so treat returned titles and links as untrusted. Check sample-data warnings and choose --output carefully because it can overwrite files.

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
