PostLake analytics

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward PostLake analytics helper that tells the agent how to read analytics from the documented PostLake API using a user-provided API key.

Install this only if you want the agent to query PostLake analytics. Use a read-only, scoped POSTLAKE_API_KEY if available, and avoid giving the agent broader PostLake permissions than analytics reporting requires.

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
