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

  • https://www.namecheap.com/domains/registration/results/?domain={domain}
  • https://www.dynadot.com/domain/search?domain={domain}

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

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