domain-hunter FAQ

How does the skill check if a domain is available?

It uses three methods: WHOIS lookup (most reliable), registrar search pages, or bulk checks via Namecheap/Dynadot. Only domains confirmed as available are presented.

Will I find promo codes for premium TLDs like .ai?

Rarely. Premium TLDs have high wholesale costs, so registrars typically don't offer promo codes. The skill will search but may return none available.

What's the difference between registration and renewal prices?

Registration price is the first-year cost, renewal price is what you pay in subsequent years. They often differ significantly, so the skill compares both.

Does Cloudflare offer domain registration?

Yes. Cloudflare offers at-cost pricing with no markup and free WHOIS privacy, making it competitive for many TLDs.

Are there minimum registration periods?

Yes, .ai domains require a 2-year minimum registration. The skill notes these requirements in recommendations.

Domain Hunter Skill

Help users find and purchase domain names at the best price.

Workflow

Step 1: Generate Domain Ideas & Check Availability

Based on the user's project description, generate 5-10 creative domain name suggestions.

Guidelines:

  • Keep names short (under 15 characters)
  • Make them memorable and brandable
  • Consider: {action}{noun}, {noun}{suffix}, {prefix}{keyword}
  • Common suffixes: app, io, hq, ly, ify, now, hub

CRITICAL: Always check availability before presenting domains to user!

Use one of these methods to verify availability:

Method 1: WHOIS check (most reliable)

# Check if domain is available via whois
whois {domain}.{tld} 2>/dev/null | grep -i "no match\|not found\|available\|no data found" && echo "AVAILABLE" || echo "TAKEN"

Method 2: Registrar search page Open the registrar's domain search in browser to verify:

open "https://www.spaceship.com/domains/?search={domain}.{tld}"

Method 3: Bulk check via Namecheap/Dynadot

IMPORTANT:

  • Only present domains that are confirmed AVAILABLE
  • Mark any uncertain domains with "(unverified)"
  • Present suggestions to user and wait for confirmation before proceeding
  • Ask user to pick their preferred options or provide feedback
  • Only move to Step 2 after user approves domain name(s)

Step 2: Compare Prices

Use WebSearch to find current prices:

WebSearch: "cheapest .{tld} domain registrar 2026 site:tld-list.com"
WebSearch: ".{tld} domain price comparison tldes.com"

Key price comparison sites:

  • tld-list.com/tld/{tld}
  • tldes.com/{tld}
  • domaintyper.com/{tld}-domain

Step 3: Find Promo Codes

Use Twitter skill to search registrar accounts:

cd <twitter_skill_directory>
python3 scripts/search_tweets.py "from:{registrar} promo code" --type Latest --limit 15
python3 scripts/search_tweets.py "{registrar} promo code coupon" --type Latest --limit 15

Use Reddit skill to search domain communities:

cd <reddit_skill_directory>
python3 scripts/search_posts.py "{registrar} promo code" --limit 15
python3 scripts/search_posts.py "{registrar} coupon discount" --subreddit Domains --limit 10

Major registrar Twitter handles:

  • @spaceship, @Dynadot, @Namecheap, @Porkbun, @namesilo, @Cloudflare

Step 4: Recommend

Present final recommendation in this format:

## Recommendation

**Domain:** example.ai
**Best Registrar:** Spaceship
**Price:** $68.98/year (2-year minimum = $137.96)
**Promo Code:** None available for .ai
**Purchase Link:** https://www.spaceship.com/

### Price Comparison
| Registrar | Year 1 | Renewal | 2-Year Total |
|-----------|--------|---------|--------------|
| Spaceship | $68.98 | $68.98  | $137.96      |
| Cloudflare| $70.00 | $70.00  | $140.00      |
| Porkbun   | $71.40 | $72.40  | $143.80      |

Important Notes

  1. Premium TLDs (.ai, .io) rarely have promo codes - wholesale costs are too high
  2. .ai domains require 2-year minimum registration
  3. Cloudflare offers at-cost pricing with no markup
  4. Renewal prices often differ from registration - always check both
  5. WHOIS privacy is free at most registrars (Cloudflare, Namecheap, Porkbun)
