DNS and domain information lookup. Use for checking DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA), WHOIS data, and domain availability. Helps with domain research, troubleshooting DNS issues, and finding if a domain is registered or free.

Live production incident investigation mode for infrastructure engineers. Use only when the user explicitly asks you to handle, investigate, or respond to an incident, or explicitly invokes the incident-response skill. Do not trigger only because the user reports a production issue, alert, error, stack trace, slow service, failed workload, or other incident-like signal.
Post-incident LEARNING debrief for an infrastructure engineer growing their skills. Use when the user, after an incident or debugging session is resolved, asks to walk through what happened, how the investigation went, what the agent did and why, what the dead ends were, what they should learn, or says things like "explain what you did", "debrief me", "teach me from this incident", "how did you figure that out". Also use when the user points to a recent incident-log-*.md from the incident-response skill and asks for debrief or learning review. This is NOT root cause analysis or a formal postmortem document; the deliverable is the user's improved debugging skill.
Interpret, explain, write, and update Finicky v4 configuration for macOS URL routing. Use when working with ~/.finicky.js or ~/.finicky.ts, reading an existing Finicky setup, authoring rewrite or handler rules, choosing browsers or profiles, debugging rule order, or migrating routing logic into Finicky.

Query DNS records, WHOIS information, and check domain availability.
./scripts/dns-records.sh <domain>
Returns all common DNS record types (A, AAAA, MX, TXT, NS, CNAME, SOA).
./scripts/dns-record.sh <domain> <type>
Query a specific record type:
A - IPv4 addressAAAA - IPv6 addressMX - Mail serversTXT - Text records (SPF, DKIM, etc.)NS - Name serversCNAME - Canonical name (alias)SOA - Start of authorityCAA - Certificate authority authorizationSRV - Service recordsPTR - Reverse DNSExample:
./scripts/dns-record.sh google.com MX
./scripts/dns-record.sh example.com TXT
./scripts/whois.sh <domain>
Returns WHOIS registration data including:
./scripts/available.sh <domain>
Checks if a domain is registered or available for purchase.
./scripts/bulk-available.sh <domain-list-file>
# or
echo -e "example1.com\nexample2.com" | ./scripts/bulk-available.sh
Check multiple domains at once.
./scripts/report.sh <domain>
Comprehensive report including:
# Check all DNS records for a domain
./scripts/dns-records.sh github.com
# Check if a domain is available
./scripts/available.sh my-cool-startup.com
