65 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

Bulk domain availability checker. Use when the user wants to check whether one or many domain names are available for registration (e.g., "is acme.com free", "check these 50 domains", "find an available .io for my brand"). Supports any TLD (.com/.net/.io/.ai/.dev/.app/...), parallel checking, three input modes (CLI args / file / stdin), bare-name + TLD-list expansion, and table/JSON/CSV output. Python stdlib only — no pip installs, no API keys.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'domain-checker' ] || [ -L ~/.agents/skills/'domain-checker' ]; then echo 'A skill folder named domain-checker already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/georgekhananaev/claude-skills-vault' "$d" && git -C "$d" checkout --quiet '89eb25139ef7281a187d82f9eebf1ff4770d3af6' -- '.claude/skills/domain-checker' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/domain-checker' ~/.agents/skills/'domain-checker' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'domain-checker' ~/.claude/skills/'domain-checker' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
