domain-info-get-{domain}

domain-info-get-{domain} is a skill for Claude Code from bobadilla-tech/requiems-api-skills. It costs 17 tokens per session (519 once invoked), scanned A, original, MIT.

An API skill that looks up a domain name’s availability and DNS records. DNS is the system that connects names such as example.com to internet services such as web servers and mail servers.

In plain words
What is it for?
Use it to inspect a domain’s A, AAAA, MX, NS, TXT, and CNAME records through the domain-info endpoint. It can help check domain availability and understand how a domain is configured.
Why use it?
It avoids having to query several DNS record types and interpret the results yourself. It reports whether the domain appears unregistered and returns records such as IPv4, IPv6, mail, name-server, and text records.

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.

Security

Grade A, and why

domain-info-get-{domain} 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 12d ago.

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 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.
