Domain checker

Run the bundled Python 3 checker. No packages, credentials or browser needed. Resolve scripts/check_domains.py relative to this SKILL.md, regardless of the current working directory.

python3 <skill-dir>/scripts/check_domains.py example.com example.dev example.ai --json

Pass complete domains, not bare brand names or URLs. For a name across several extensions, expand them into explicit domains. The helper supports domains directly under a TLD, including .com, .dev, .ai and .cloud; multi-label suffixes such as .co.uk are outside its scope.

The script discovers registry endpoints from IANA and runs up to 4 requests concurrently. Use small batches. It sends domain queries to public registries, not registrar shopping carts.

JSON output is an array of {domain, status, detail} objects. Without --json, output is a short list and elapsed time.
