Security checks for vulnerabilities and agentic risk

Overview

The skill describes a narrowly scoped file-proof workflow with explicit user control over permanent public records.

Limit the local server to the folder containing the intended files and review the pinned npm package before running it. Anchors are public and irreversible; keep the private draft securely with the original file. This review assessed the instructions, not the unbundled server implementations or their privacy guarantees.

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
