Security audit

Postsyncer

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward PostSyncer guide that uses an API key and can create social posts, which matches its stated purpose.

Install only if you trust PostSyncer and the postsyncer CLI you will run. Use a revocable, least-privileged API key if available, and review workspace IDs and post text before letting an agent create or schedule posts.

Missing User Warnings

Low
Confidence
87% confidence
Finding
The skill instructs the user to create a social media post via an external SaaS platform but does not explicitly warn that the provided text will be transmitted to a third-party service and may be published to linked accounts. In an agent context, that omission can cause users to share sensitive or unintended content without realizing it leaves the local environment and may become publicly visible.
