Dns Records

Look up DNS records for any domain — A, AAAA, MX, NS, TXT, CNAME, SOA. Use when asked to check DNS records, find a domain's IP address, look up mail servers,...

Security Scan

The skill is internally consistent: it only performs DNS lookups via the system dig command or Python socket fallback, requires no credentials or installs, and the included code matches the SKILL.md instructions.

Purpose & Capability

Name/description (DNS record lookup) matches the requested/implemented functionality. No unrelated binaries, environment variables, or credentials are requested. The provided scripts implement only DNS queries for the claimed record types.

Instruction Scope

SKILL.md instructs running the included Python script or dig; the scripts execute dig (if present) or use socket.getaddrinfo as a fallback for A/AAAA. They do not read files, environment variables, or transmit data to external endpoints beyond standard DNS resolution. Note: only A/AAAA have a socket fallback; other types rely on dig.

Install Mechanism

No install spec (instruction-only). The package includes two identical script files (dnscheck.py and scripts/dnscheck.py); no downloads or external installs are performed. Low installation risk.

Credentials

No environment variables, secrets, or config paths are requested. The lack of credentials is proportional to a DNS lookup tool.

Persistence & Privilege

always is false and the skill does not request persistent system privileges or modify other skills/configs. It runs on demand and does not store credentials.

Assessment

This skill appears safe and does what it says: run DNS queries via dig or Python. Before installing, consider that: (1) the tool will perform network DNS queries for any domain you ask it to — those queries go to your system resolver (so the resolver operator will see the domain names); (2) dig is invoked via subprocess when available (normal for this purpose); and (3) the scripts duplicate each other and only implement simple lookups (A/AAAA have a Python fallback; MX/NS/TXT/CNAME/SOA require dig). If you need to avoid leaking queried domains to your network resolver, don't run it or run it in an environment with a privacy-preserving DNS setup.

DNS record lookup with multi-type support and JSON output.

Commands

# Full DNS check (all common record types)
python3 scripts/dnscheck.py github.com openclaw.ai

# Specific record types only
python3 scripts/dnscheck.py -t A MX example.com

# JSON output for scripting
python3 scripts/dnscheck.py --json example.com

Record Types

• A — IPv4 addresses
• AAAA — IPv6 addresses
• MX — Mail servers
• NS — Nameservers
• TXT — SPF, DKIM, verification records
• CNAME — Canonical name aliases
• SOA — Start of authority

Features

• Queries all record types by default
• Uses dig when available, falls back to Python sockets for A/AAAA
• JSON output mode for automation
• Multiple domains in one command
