dns-lookup

dns-lookup is a skill for Claude Code, Codex from fisker086/AIOps. It costs 0 tokens per session (154 once invoked), scanned A, original, Apache-2.0.

A tool for looking up DNS records, which tell the internet where a domain's services are located and how email is routed. It can query records such as website addresses, mail servers, text entries, and name servers.

In plain words
What is it for?
Use it to inspect a domain's A or AAAA address, MX mail settings, TXT records, NS name servers, CNAME aliases, or SOA information, including through a custom DNS server.
Why use it?
It provides DNS answers without requiring separate command-line tools or manually choosing a DNS server. The lookup requires network access.

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

dns-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 9d 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.
