EpicTexting: Send SMS from Your AI Agent (Twilio)
Security checks for vulnerabilities and agentic risk
Overview
This skill provides SMS sending and message lookup with explicit approval before every send and clearly disclosed account access.
Review recipients and text before approving each send, and consider SMS charges. The [provider](https://www.epictexting.app/) says it stores your Twilio credentials, so review that access before connecting. The hosted service implementation is outside the bundled artifact review.
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
Vulnerability Patterns
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
