What is domaininfo?
domaininfo is a robust utility designed for the Openclaw Skills ecosystem that automates the gathering of domain intelligence. It streamlines technical reconnaissance by aggregating data from WHOIS, DNS queries, and security headers into a consolidated, easy-to-read report.
This skill prioritizes security and efficiency, implementing strict input validation and timeout-bounded external calls. It is particularly valuable for developers and security researchers who need to verify domain ownership, inspect email authentication records like SPF and DMARC, or check the validity of TLS certificates without manual overhead.
domaininfo Use Cases
- Investigating domain ownership and registrar details using WHOIS lookup.
- Verifying email deliverability configurations by checking SPF, DMARC, and DKIM records.
- Performing quick security audits of TLS/SSL certificate issuers and expiration dates.
- Automating website visual verification via optional browser-based screenshots.
- Resolving domain hostnames to IP addresses with associated country-level geolocation.
How domaininfo Works
- Domain Extraction: Validates the input by stripping prefixes (http/https/www) and extracting domains from email addresses.
- WHOIS & DNS Querying: Executes safe shell commands with 10-second timeouts to retrieve registrar and A/AAAA/NS/MX records.
- Geolocation Mapping: Resolves hostnames to IPs and queries country codes to identify the server's physical location.
- Security Auditing: Performs TXT record lookups for email security protocols and inspects certificate chains via openssl.
- Optional Visualization: If environment-compatible tools like Playwright are detected, it captures a high-resolution screenshot.
- Unified Reporting: Aggregates all collected data into a single, comprehensive response to ensure a clean user experience.
domaininfo Setup
Ensure your environment has the necessary networking utilities installed. This skill leverages standard CLI tools for its core logic within the Openclaw Skills framework.
# Ensure required networking tools are available
sudo apt-get install whois dnsutils openssl
# Optional: To enable screenshot functionality, ensure Playwright is configured
npm install playwright
domaininfo Data Schema & Taxonomy
The skill organizes its output into a structured report following this metadata taxonomy:
| Category | Data Points Captured |
|---|---|
| WHOIS | Registrar name, registration dates, and status. |
| DNS Records | A, AAAA, Name Servers (NS), and Mail Exchangers (MX). |
| Email Security | SPF records (v=spf1), DMARC policies, and DKIM selectors. |
| Network | IP address geolocation (ISO country codes). |
| Security | TLS Certificate issuer and expiry date. |
| Assets | PNG screenshot of the landing page (optional). |
domaininfo Advanced Features
- Strict Buffer-First Execution: Guarantees zero partial output; the report is only delivered once all data points are collected.
- Smart Extraction: Automatically handles dirty input including full URLs and email addresses to find the root domain.
- Conditional Screenshotting: Dynamically detects the presence of the OpenClaw browser tool or Playwright before attempting visual captures.
- Security Hardening: Includes built-in command injection prevention and regex-based input sanitization.
- Internal Caching: Optimized IP-to-country lookups to prevent rate-limiting on external geolocation APIs.
