Surfline (public)

Security checks across malware telemetry and agentic risk

Overview

This Surfline skill appears to be a straightforward public forecast helper with limited local caching and no evidence of hidden or harmful behavior.

Install if you are comfortable sending search terms and spot IDs to Surfline. Cached forecast data and your favorites list may remain on your machine in the documented Surfline cache/config paths unless you delete them or choose a different cache location.

Finding
The skill documentation describes scripts that perform network access, read and write files for caching and favorites, and may access environment-derived paths, yet the skill declares no permissions. This creates a transparency and policy problem: users or hosting platforms may grant the skill more trust than warranted, and automated enforcement cannot accurately constrain its behavior.
