What kr-whois-lookup does

The skill queries the public data portal WHOIS API through k-skill-proxy. It looks up public registration details for .kr domains, IP addresses, and autonomous system numbers. The tool operates strictly in read-only mode.

The agent gets its full instructions by executing npx -y @nomadamas/k-skill@0 instruct kr-whois-lookup. The CLI detects the runtime, such as Dolshoi vault or CloakBrowser, and prints the applicable steps. Running the command requires Node.js 18+.

Safety rules strictly forbid storing plaintext credentials in chat or shell arguments. Executing payments, sending messages, or submitting forms without explicit approval beforehand is blocked.

What it helps with

  • inspect WHOIS registration records for .kr domains
  • retrieve ownership details for an IP address via k-skill-proxy
  • look up public autonomous system data by AS number

Example prompts for the agent

  • Look up WHOIS details for domain example.kr
  • Check public registration info for this IP address via k-skill-proxy
  • Find the registered AS details for this network

# kr-whois-lookup

<!-- k-skill:cli-stub — generated by scripts/generate-skill-stubs.js; edit skill.json / instruction.md instead -->

## Get the full instructions (required first step)

Run this and follow its output as the primary instructions for this skill:

```bash
npx -y @nomadamas/k-skill@0 instruct kr-whois-lookup
```

The CLI detects the current runtime (Dolshoi vault/CloakBrowser vs generic) and prints only the applicable instructions, always up to date. Helper files bundled with the CLI are listed by:

```bash
npx -y @nomadamas/k-skill@0 files kr-whois-lookup
```

Keep the CLI and every coding-agent skill install current (including Vercel Agent Skills) with:

```bash
npx -y @nomadamas/k-skill@0 update
```

If `npx` is unavailable, install Node.js 18+ or follow https://github.com/NomaDamas/k-skill#readme, or read the source instructions at https://github.com/NomaDamas/k-skill/blob/main/kr-whois-lookup/instruction.md.

## Hard rules even without the CLI

- Never execute payment, message/email delivery, final submission, cancellation, or public posting without the user's explicit approval immediately beforehand.
- Never ask for, print, or store plaintext credentials in chat, files, or shell arguments.
- Never bypass legal, physical-presence, CAPTCHA, identity-proofing, or electronic-signature boundaries.
