What is namebeta-lookup?

A lookup tool for checking whether domain names are registered or available across NameBeta’s list of domain endings. For registered domains, it also checks whether a website is running at the address.

Use it to research names for a brand or product, list available domains, and distinguish registered domains with deployed websites from those that are parked or unreachable.

It gives you domain availability and basic website status in one check instead of checking each ending and website separately.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00083	$0.00601
Opus 5.5	$0.00033	$0.00240
Sonnet 5.5	$0.00017	$0.00120
Haiku 4.5	$0.00008	$0.00060

Security

Grade A, and why

namebeta-lookup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/probe-sites.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

NameBeta 关键词查询

用户在对话里丢一个关键词、品牌或产品名时：先查 NameBeta 后缀清单，再检查已注册域名有没有网站。

注册了你还得给我检查一下是否部署网站了

Workflow

Call lookup_domain with the user's exact keyword. Do not expand, synonym, or long-tail it.
Report list totals: suffix count, registered vs available, taken domains (created / expiry / registrar), full available list.
If any list suffix (or extra split) is registered or for-sale: probe every one. Availability alone is not enough.
Put the suffix tables and the site-probe table in the canvas. Summarize .com plus deployed vs parked vs unreachable in chat.
If nothing is registered, say so and skip the probe. Do not invent site status.

Probe registered domains

Run the bundled script from the skill directory (HTTPS first, then HTTP; 10s timeout; follows redirects):

node scripts/probe-sites.mjs domain1.com domain2.net

If the skill lives in this repo as a project skill:

node .cursor/skills/namebeta-lookup/scripts/probe-sites.mjs domain1.com domain2.net

Pass every taken / for-sale hostname from the NameBeta list, plus taken extra splits.

Do not treat DNS A records, registrar nameservers, or a 200 parking page as "deployed". Read deployed and kind from the script JSON.

`kind`	Report as
`live`	已部署
`parked`	未部署（停放/待售）
`coming_soon`	未部署（即将上线）
`empty`	未部署（空白页）
`redirect`	能打开，跳转到 {finalHost}
`unreachable`	打不开
`error`	打不开（HTTP {status}）

deployed is true only for live.

Canvas / chat

Include a 已注册 / 站点探测 table: domain, 能不能打开 (HTTP status or error), 站点情况 (kind + title or final URL).

Source link: the NameBeta search URL from the tool result.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
