Data Enricher

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward lead-enrichment guide that uses disclosed email lookup methods and local batch output, with privacy handling worth watching.

Before installing, confirm you are comfortable sending lead domains to Hunter.io with your API key and storing enriched contact emails in a local JSON file. Keep the output file in a protected workspace, delete it when no longer needed, and ensure the Notion sync target is the intended lead database.

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
