Security checks for vulnerabilities and agentic risk

Overview

The bundled skill uses a small local script to prepare article drafts, with clear limits and no automatic publishing or external data transfer.

Anonymize notes before processing; the script does not redact them automatically. Use a dedicated output folder because digest.md is overwritten, and review the draft before publishing. The optional unsigned Windows app is unnecessary for this workflow and requires a separate trust decision; its listed checksum alone does not establish safety.

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
