Agent Phone SMS

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Anima phone/SMS setup guide with expected external API use and paid-service guidance, not hidden or destructive behavior.

Install only if you intend to use Anima for agent phone/SMS/voice. Approve signup, billing upgrades, recipients, message bodies, and calls explicitly, and avoid placing transcripts, OTPs, or API keys into chat memory or non-Anima services.

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
