Use Cases
- Check if your website pages are accessible
- Find broken links in your content
- Monitor external resource availability
Usage Guidance
This appears safe for its stated purpose. Be aware that it sends a request from your environment to the URL you provide, so avoid testing private/internal URLs unless you intend to expose that network request. No credentials should be needed.
Capability Tags
Capability Assessment
Purpose & Capability
The implementation matches the stated URL health-checking purpose, though the documentation claims redirect-chain reporting while the script only reports the final URL and leaves the redirects list empty.
Instruction Scope
Usage is limited to a direct command that checks one supplied URL; there are no instructions to run automatically, modify files, or perform broad scanning.
Install Mechanism
There is no install step or dependency installation; the included Python script uses only the standard library.
Credentials
The script performs outbound network access to the URL supplied by the user, which is expected for this skill. The provided capability signal says sensitive credentials are required, but the metadata, README, and code show no credential use.
Persistence & Privilege
No persistence, background process, privilege escalation, file writes, or credential storage is shown.
How to Use
