What its author says it does
Copied from the file, not written here
Generate the exact DNS records for pointing a custom domain at Vercel, Netlify, Cloudflare Pages, or GitHub Pages — and validate the user's actual records before they flip the domain. Use whenever the user mentions custom domains, DNS, nameservers, 'domain not working', CNAME/A records, or connecting a purchased domain to a deployed site. Runs fully offline — no API keys, no network, no credentials.

dns-cutover
Part of shipsafe — offline deploy-safety skills. Every script is stdlib-only Python 3.8+; nothing leaves the machine.
Two modes:
# 1) What records do I need?
python3 scripts/dns_cutover.py plan <domain> <platform>
# 2) Are my records right? (paste zone export or `dig +noall +answer` output into a file)
python3 scripts/dns_cutover.py check <domain> <platform> <records_file> [--json]
Platforms: vercel, netlify, cloudflare-pages, github-pages.
check validates apex and www records, and additionally catches the three classic cutover mistakes:
- apex CNAME — illegal on standard DNS, silently breaks MX/email at most registrars
- stale extra A records — round-robin traffic to the dead old host (looks like 'site randomly down')
- conflicting A + CNAME on the same name
Process to walk the user through: lower TTL to 300s the day BEFORE → run plan → set records → export/dig the records into a file → run check → only then flip. After cutover, verify HTTPS on BOTH apex and www — cert issuance is the step that fails silently.
Some values are project-specific (e.g. <yoursite>.netlify.app); the script marks these and the user's dashboard value wins.
Exit codes: 0 ok, 1 problems found.
