What it does
Domain Hunter is an agent skill from ReScienceLab/opc-skills. Search domains, compare prices, find promo codes, get purchase recommendations. Use when user wants to buy a domain, check domain prices, find domain deals, compare registrars, or search for .ai/.com domains.
Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `.claude-plugin/plugin.json`, `examples/auto-video-editing-domain.md` and `references/registrars.md`).
It works with Cloudflare. The repository describes itself as: Agent Skills for Solopreneurs. The licence is Apache-2.0.
When your agent uses it
- User wants to buy a domain
- Check domain prices
- Find domain deals
- Compare registrars
Example prompts
- “/domain-hunter”
Requirements
- Python 3
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 8295f4a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
spaceship.com
Also links to:
namecheap.comdynadot.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Domain Hunter loads about 958 tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 267 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 15Use 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 10Major 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)
