Document Similarity

Security checks for vulnerabilities and agentic risk

Overview

This skill uploads user-selected documents to PDFAPIHub to compare visual similarity, and that cloud processing is clearly disclosed.

Install only if you are comfortable sending the compared documents or public URLs, plus your PDFAPIHub API key, to PDFAPIHub. Do not use it for confidential files unless the provider's privacy and retention terms are acceptable to you.

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

Vague Triggers

Confidence
87% confidence
Finding

This is a manifest file, so vague-trigger review applies. The description states what the skill does but provides no specific trigger phrases, scope boundaries, or exclusion conditions, which can make activation criteria ambiguous in systems that rely on manifest text for routing.
