Uptime Checker

Security checks across malware telemetry and agentic risk

Overview

This is a straightforward uptime-checking skill whose network requests, optional headers, and local history file match its stated purpose.

Install is reasonable if you need a local URL checker. Use Authorization or Cookie headers only with trusted endpoints, prefer GET or HEAD for routine checks, and keep saved history files private if they contain internal service URLs.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The README explicitly shows sending an Authorization header to a remote endpoint, but gives no warning that credentials will be transmitted to whatever URL the user supplies. In a skill centered on checking arbitrary URLs, this is risky because users may test untrusted or mistyped destinations and inadvertently disclose bearer tokens.
