HTMLPix API

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward HTMLPix API reference and integration helper; its network examples are expected for using that API.

Before installing, users should understand that using the skill may lead the agent to prepare or run HTMLPix API requests with their HTMLPIX_API_KEY and send selected template code, variables, or generation prompts to HTMLPix. Keep the API key server-side as the skill advises and avoid sending secrets or private data in template variables or prompts unless intended.

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
