Domain checker

Run the bundled Python 3 checker without packages, credentials or a browser. Resolve scripts/check_domains.py relative to this SKILL.md, regardless of the working directory.

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

Use complete domains, not bare brand names or URLs; expand each name/TLD combination. Only domains directly under a TLD are supported (e.g. .com, .dev, .ai, .cloud), not multi-label suffixes such as .co.uk.

The script discovers endpoints through IANA and queries public registries, not registrar shopping carts. Use small batches; concurrency is capped at 4 requests.

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