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, not from a name you fell in love with" methodology. Uses Vercel CLI + whois + Domainr API + Namecheap API + agent-browser for the pieces each tool actually reliably supports (multi-tool ensemble because no single tool covers eve

Tokens, turns and time describe resource use, not a dollar price.
One of 12 test cases the skill fixed. Same model, same prompt, with and without the skill.
Before starting a multi-tool domain discovery and pricing session, what command line environment check must be performed for Vercel CLI, and what three environment variables are required for Namecheap API integration?
| Checked | Without skill | With skill |
|---|---|---|
| Executes vercel whoami to verify Vercel CLI status | Missed | Passed |
| Requires setting the NAMECHEAP_API_KEY environment variable | Passed | Passed |
The instructions your model reads when the skill loads.
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).
Defaults to .com only. Only deviate (.dev, .co, .io, .ai) if the project is dev-tooling-only or the user explicitly asks.
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).
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.
Ask what the product does + the feeling/category. Brainstorm 20–40 candidate domains using these preferences (in order):
try (TryGamma, TryRoam), use (UseMotion, UseChalk), with (WithCove, WithFrame), join (JoinHomebase, JoinHonor)get (GetMagic, GetResponse), go (GoCardless, GoFundMe), hey (HeyMarvin, HeyHenry), the (TheBrowserCompany, TheDyrt — editorial vibe)test cases passed, vs 7 / 19 without
