## What it does

The skill walks from budget to purchase. You name what you would pay for a good .com, then it brainstorms 20–40 candidates, checks availability, cross-checks with whois, pulls registrar quotes, sweeps the aftermarket, and screens trademarks plus social handles. It defaults to `.com` only — it moves to `.dev`, `.io` or `.ai` when the project is dev-tooling-only or you ask for it.

Each tool covers its own part: `vercel domains check` and `vercel domains price` for availability and quotes, `whois` as ground truth on registration, Domainr and Namecheap for cross-checks. One catch worth knowing: `vercel domains check` is solid for `.com` and most gTLDs but errors out on `.ai`, `.dev`, `.io` and `.app`, so those skip straight to `whois`. In whois the skill tells you to look for registered signals before available ones — a parked page can carry for-sale wording, and a taken name then reads as free.

Check your environment first: Vercel CLI with `vercel login` done, the `whois` utility, and keys in environment variables for Domainr and Namecheap. Both of those are optional, and without them the matching cross-check steps are skipped.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add coreyhaines31/makerskills --skill domain -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/domain/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/domain/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add coreyhaines31/makerskills --skill domain -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/domain/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add coreyhaines31/makerskills --skill domain -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/domain/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install coreyhaines31/makerskills domain
```

2. **Manually: put the files in place**
- File: `.github/skills/domain/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add coreyhaines31/makerskills --skill domain -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/coreyhaines31/makerskills --path skills/domain
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/domain/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add coreyhaines31/makerskills --skill domain -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/coreyhaines31/makerskills/tree/HEAD/skills/domain/SKILL.md

## When to use it
- pick a project name from domains that are actually unregistered
- find the aftermarket price of a taken .com
- screen a domain against USPTO trademarks
- check whether the social handles are free
- filter out candidates above your budget before you get attached

## Example prompts
- /domain — help me name a new project
- check availability for these .coms and show me prices
- is there a trademark on this name, and are the socials free

name: domain
description: "When you want to brainstorm and check available .com domains for a new project — brand naming, aftermarket pricing (HugeDomains / Afternic / Sedo / Dan), USPTO trademark screening, and social handle availability. Built on Laura Roeder's \"work backwards from availability\" method. Combines Vercel CLI, whois, Domainr, Namecheap, and agent-browser, each for what it reliably does. Workflow: budget → brainstorm → availability check → whois cross-check → price → aftermarket sweep (plus liveness probe and drop-watch) → bucket → negotiate → trademark + socials → buy. Triggers on \"/domain,\" \"find a domain,\" \"check domain availability,\" \"brainstorm a domain,\" \"what .com is available for X,\" \"domain hunt,\" \"name my project,\" \"is X.com available,\" \"aftermarket price on X.com,\" \"trademark check for X.\""

# /domain — Brainstorm + check available .com domains

Multi-tool workflow to find a great, affordable, available .com for a new project. Built on Laura Roeder's rule: **work backwards from what's actually available — don't fall in love with a name first** ([source](https://lauraroeder.com/how-i-nabbed-the-com-for-my-bootstrapped-startup-without-spending-a-million-bucks-6dc35c4606e9)).

Defaults to `.com` only. Only deviate (.dev, .co, .io, .ai) if the project is dev-tooling-only or the user explicitly asks.

## Step 0 — Environment checks

Verify these before proceeding (surface install commands if missing, don't try to install silently):

| Tool | Check | Install if missing |
|---|---|---|
| Vercel CLI | `vercel whoami` | `npm i -g vercel && vercel login` |
| whois | `which whois` | `brew install whois` (macOS) |
| Domainr API key | `[ -n "$DOMAINR_API_KEY" ]` | Get free key at rapidapi.com/domainr/api/domainr, add to `~/.zshenv` |
| Namecheap API | `[ -n "$NAMECHEAP_API_KEY" ] && [ -n "$NAMECHEAP_API_USER" ] && [ -n "$NAMECHEAP_CLIENT_IP" ]` | Enable API at ap.www.namecheap.com/settings/tools/apiaccess/, add 3 env vars, whitelist your IP |

Domainr + Namecheap are optional — the workflow degrades gracefully without them (skips the corresponding cross-check steps).

## Step 1 — Set the budget

Ask: **what would you pay for a great .com on this project?** Anchor defaults:

| Budget | What it buys |
|---|---|
| **$0** | Only unregistered domains (rare for anything good) |
| **$250–$1k** | Aftermarket sweet spot (HugeDomains is the standout — Laura found "a ton of great .com's available for less than $1k") |
| **$1k–$2k** | Laura's Paperbell.com range — plenty of brandable options |
| **$2k+** | Premium |

**Filter all candidates to under-budget BEFORE falling in love.**
