Facebook Marketplace

Security checks across malware telemetry and agentic risk

Overview

This is a Markdown-only Facebook Marketplace helper with disclosed local notes and user-approved Facebook or Messenger use.

Install only if you want Marketplace advice that may keep local notes. Before using it, decide whether to allow ~/facebook-marketplace/ persistence, avoid storing sensitive personal details, and personally confirm signed-in Facebook actions such as posting listings, sending messages, payments, reports, or appeals.

Vague Triggers

Medium

Confidence: 90% confidence
Finding: The skill defines activation triggers broadly across Facebook Marketplace, local selling, flipping, pickup, and scam topics, and instructs the agent to clarify boundaries only within the first exchanges rather than before activation. That can cause the skill to engage in conversations outside its intended scope, increasing the chance of unwanted intervention, incorrect persistence behavior, or unsafe advice being applied too broadly.
