## What it does

The skill generates 5-10 domain ideas from a project description, then checks availability through WHOIS, a registrar search, or bulk checks at Namecheap and Dynadot. It presents confirmed available options and waits for the user to choose one.

It then uses WebSearch and comparison services to check current registrar pricing, including registration and renewal costs. Promo-code research calls the Twitter and Reddit skills through `search_tweets.py` and `search_posts.py`. Those skills are required for that part, so check they are installed first.

The final recommendation lists the domain, registrar, price, promo code, and a comparison of terms. It accounts for the 2-year minimum registration for .ai domains, while promo codes are rare for premium extensions.

# 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)**
```bash
# 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:
```bash
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:

```bash
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:

```bash
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/
