cf-domain-hunter

English | 中文

A standard skill that finds, verifies, and prices domain names using the free Cloudflare CLI (cf) — no API keys, no web scraping, no third-party services. Works with Claude Code, Pi, Codex, and other skill-compatible agents.

Every availability result is an authoritative real-time registry check with Cloudflare's at-cost pricing. Only verified-available domains are ever presented to the user.

Features

• 🔍 Suggest — generate brandable, short domain candidates from a business description (double-pinyin friendly for Chinese users)
• ✅ Verify — authoritative availability check via cf registrar registrations check (real registry, not cache)
• 💰 Price — Cloudflare at-cost USD pricing for registration and renewal
• 🛡️ Dependency guard — detects missing cf CLI or missing login and walks the user through setup before any query

Requirements

• Any skill-compatible agent (Claude Code, Pi, etc.)
• Cloudflare CLI (cf) installed and logged in:

npm install -g cf
cf auth login

Domain availability/pricing endpoints are account-scoped. Without login they return [9106] Authentication failed — the skill detects this and guides you through cf auth login automatically.

Installation

Option 1: One command with the skills CLI (recommended)

The skills CLI installs directly from GitHub and auto-detects your agent (Claude Code, Pi, Codex, Cursor, and 80+ more):

# Project-level (this project only):
npx skills add https://github.com/ifyour/cf-domain-hunter
# User-level (all projects):
npx skills add -g https://github.com/ifyour/cf-domain-hunter

Option 2: Natural language

Just send your agent the repo link and ask:

Install the skill from https://github.com/ifyour/cf-domain-hunter

The agent will run the install command for you and pick the right skills directory.

Usage

1. Natural language (auto-trigger)

Just describe what you want — the agent matches the skill by its description:

Find some domains for an after-school learning video business for elementary school students, double-pinyin preferred

Find me 10 available domains for a kids' cartoon learning site, under $15/year

2. Explicit skill command

/cf-domain-hunter domains related to free image hosting, check both .com and .xyz

(Claude Code uses /cf-domain-hunter … syntax; other hosts may differ.)

Arguments after the command are appended to the skill as your request.

3. Manual reference

Mention the skill name in your prompt: "Use the cf-domain-hunter flow to check if katong.tv is available for registration".

What you get

## Recommendation

**Domain:** katong.tv
**Price:** $25.00/year (same registration and renewal)
**Registrar:** Cloudflare (at-cost, free WHOIS privacy)
**Verified:** ✅ registrable: true

### Available Candidates (verified in real time)
| Domain | Year 1 | Renewal |
|--------|--------|---------|
| katong.tv | $25.00 | $25.00 |
| xiaoxuetv.com | $10.46 | $10.46 |

### Unavailable
- donghua.com — already registered
- xueke.vip — premium-priced domain

How it works

Step	Command	Notes
0. Dependency check	cf auth whoami	Stops and guides install/login if missing
1. Generate ideas	—	10–20 short, brandable candidates
2. Suggestions (optional)	cf registrar registrations search	Cached, non-authoritative
3. Verify (required)	cf registrar registrations check	Real-time registry, max 20 domains/request, returns pricing
4. Recommend	—	Only registrable: true domains, waits for your confirmation

Notes & Limitations

• Registration itself is done via the Cloudflare dashboard (https://dash.cloudflare.com/?to=/:account/domains/register) — the check/verify flow is fully CLI-based
• domain_premium domains cannot be registered via the API (dashboard only, higher price)
• Max 20 domains per check request
• Pricing is Cloudflare's at-cost USD price — usually the cheapest retail option, so no separate price comparison is needed
