What problem does it solve?
You know what you are building but every good .com is taken and manual WHOIS checking across extensions is tedious.
Who is it for?
Solo builders at project kickoff, rebrand, or pre-launch who want available domains across several TLDs in one agent session.
Skip if: Teams that already own a registered domain and trademark-cleared brand, or anyone who only needs DNS or hosting setup without naming work.
When should I use this skill?
Starting a new project or company, launching a product, creating a personal brand, rebranding, registering a side-project domain, or finding alternatives when your first choice is taken.
What do I get? / Deliverables
You leave with a prioritized list of available (or realistically alternative) domains, extension options, and naming rationale ready for registration and brand rollout.
- Ranked domain name shortlist with extension notes
- Availability-oriented alternatives when top picks are taken
- Brief branding rationale per recommended name
