Security checks for vulnerabilities and agentic risk

Overview

This is a coherent SEO content-briefing skill with disclosed web and SEO-tool research behavior and no executable code or persistence.

Before installing, be aware that this skill may use web research and available SEO provider tools to inspect target sites and competitors. Avoid providing confidential client information unless you have permission to use it, and review generated case-study details before publication.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

Vague Triggers

Confidence

Finding

The invocation phrases include very generic terms such as "outline for," "content plan," and "write a brief," which can match many ordinary writing or planning requests outside SEO briefing. This can cause the skill to activate in contexts where the user did not intend competitive SEO analysis, leading to scope hijacking, unnecessary data fetching, or inappropriate structured output.

Missing User Warnings

Confidence

Finding

The case study guidance normalizes including client situation and results while only suggesting anonymization 'if needed,' which can lead an agent to disclose identifiable client details, commercially sensitive information, or regulated personal data in generated briefs. In a content-generation skill, this increases the chance that users are encouraged to publish or request case studies that mishandle confidential information.

Finding

Throughout the templates, the document repeatedly states that FAQPage should not be added for Google visibility and that no AI or ranking benefit is confirmed (for example L021, L037, L070, L088, L100). The homepage line "FAQ (for GEO) | AI search visibility" directly conflicts with that documented position by asserting an AI-visibility purpose for FAQ content.
