Security audit

Add JSON-LD to your app/site

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill for adding JSON-LD to websites, with no hidden code, persistence, or credential handling found.

Before installing, know that the skill may be invoked for broad SEO or site-discoverability requests. Review generated JSON-LD before publishing, especially Person.sameAs profile links or knowledge-graph identifiers, because those values become public site metadata.

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 description says to use this skill whenever the user mentions broad topics like SEO metadata, knowledge graph, or wanting to make a personal site, blog, or portfolio more discoverable, including when they do not mention JSON-LD explicitly. These activation conditions are expansive and overlap with many general website/SEO requests, making it unclear when this skill should activate versus more general SEO or metadata guidance.
