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)
