Copy

Installs into your user profile and puts it on your PATH — no admin rights. The download is verified against its published checksum, and nothing is installed if it does not match. Open a new terminal afterwards.

Requires Go 1.25 or later.

Features

Use it from your AI agent

RegisterDomainCLI ships with an agent skill: a single SKILL.md in the format every major coding agent reads. This command installs it into the two directories that cover all of them, so your coding agent can search, register, and manage DNS on your behalf.

Linux and macOS

(set -e; TMP=$(mktemp "${TMPDIR:-/tmp}/domain-cli.XXXXXX"); trap 'rm -f "$TMP"' EXIT
curl -fsSL https://registerdomaincli.com/skill/SKILL.md -o "$TMP"
for d in ~/.claude/skills ~/.agents/skills; do
  mkdir -p "$d/domain-cli"
  install -m 644 "$TMP" "$d/domain-cli/SKILL.md"
done)

Windows (PowerShell)

$ErrorActionPreference = 'Stop'
$tmp = [System.IO.Path]::GetTempFileName()
try {
  Invoke-WebRequest https://registerdomaincli.com/skill/SKILL.md -UseBasicParsing -OutFile $tmp
  foreach ($d in "$HOME\.claude\skills", "$HOME\.agents\skills") {
    New-Item -ItemType Directory -Force -Path "$d\domain-cli" | Out-Null
    Copy-Item $tmp "$d\domain-cli\SKILL.md" -Force
  }
} finally { Remove-Item $tmp -Force -ErrorAction SilentlyContinue }
