Schema Markup

Security checks for vulnerabilities and agentic risk

Overview

This skill provides structured-data guidance and examples; its activation wording is broad, but the artifact shows no hidden code, persistence, credential use, or unsafe behavior.

Before installing, note that this skill may activate for broad schema-related wording and may read local project-context files when present to tailor recommendations. Its behavior is otherwise limited to schema markup guidance, examples, and validation advice.

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

Finding

The manifest description contains an unusually broad list of trigger phrases, including generic terms like "schema," "FAQ schema," and "missing structured data," which can cause the skill to activate in contexts where the user did not actually request this capability. Over-broad activation increases the chance of irrelevant tool routing, context leakage into the wrong workflow, and user confusion, even though the skill content itself is not overtly malicious.
