Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: api.vercel.com.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

About this skill

What it does

The domain-check skill allows you to verify if a given domain is registered and provides basic information about its registration. It can determine if a domain exists, retrieve the registrar, and potentially show other details like creation date. This helps in tasks related to website verification, brand protection, or general online research.

When to use it

  • Website Verification: Confirm whether a specific website URL is valid before proceeding with automated actions.
  • Brand Protection: Check if someone has registered a domain name similar to your company's branding.
  • Research & Due Diligence: Gather preliminary information about a domain during online investigations or market research.
  • Lead Generation: Validate potential leads by checking the existence of their website domains.

Key capabilities

  • Domain Existence Check
  • Registrar Retrieval
  • Basic Domain Information (potentially creation date)

Example prompts

  • "Is 'example.com' a registered domain?"
  • "Who is the registrar for 'mycompanywebsite.net'?"
  • "Check the domain information for 'newproductlaunch.org'."

Tips & gotchas

The accuracy of retrieved information depends on publicly available WHOIS data, which can sometimes be incomplete or obscured by privacy services. Results may vary depending on the domain’s configuration and registrar policies.
