Domain Hunter

resciencelab/opc-skills

Checks domain availability via WHOIS, compares prices across registrars like Spaceship and Cloudflare, and hunts down promo codes by scraping Twitter and Reddit. Generates brandable domain ideas based on your project description and won't show you anything that's already taken. The workflow is thorough: it verifies availability first, then price shops across comparison sites like tld-list.com, then digs through social media for discount codes before giving you a final recommendation with a price table. Honest about the reality that premium TLDs like .ai rarely have promos because wholesale costs are already high. Saves you the tedium of checking ten different registrars manually.

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

  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)
