Free domain research and availability checking. No API keys or credentials required. Uses RDAP (1195+ TLDs) with whois CLI fallback for universal coverage. Checks if domains are available, searches keywords across TLDs, performs WHOIS/RDAP lookups, checks expiry dates, and finds nameservers. Use when the agent needs to: check if a domain is available, search for domains, find who owns a domain, check domain expiration, get nameservers, bulk check domains, or do any domain research. Triggers on: 'check domain', 'is domain available', 'search domains', 'domain availability', 'who owns this domain', 'whois', 'domain expiry', 'when does domain expire', 'nameservers for', 'domain research', 'find domains for', 'domain ideas', 'bulk domain check'.

Domain Research

Free domain availability checking and WHOIS/RDAP lookup. Zero credentials. Works out of the box.

How it works: RDAP protocol (1195+ TLDs, JSON, fast) with whois CLI fallback for TLDs RDAP doesn't cover (.io, .co, .me, .sh, .gg, .so, etc). Parallel lookups for speed.

CLI Script

SCRIPT="skills/domain-research/scripts/domain-lookup.py"

No env vars, no API keys, no setup. Just run it.

Commands

Check availability

# Single or multiple domains (comma-separated)
uv run "$SCRIPT" check "example.com"
uv run "$SCRIPT" check "myproject.com,myproject.io,myproject.ai,myproject.dev"

Search keyword across TLDs

# Default: .com .net .org .io .co .ai .dev .app .xyz .me .tech .cloud + more
uv run "$SCRIPT" search "myproject"

# Custom TLDs
uv run "$SCRIPT" search "myproject" --tlds ".com,.io,.ai,.dev,.app,.co"

WHOIS / RDAP lookup

# Full registration details (registrar, dates, status, nameservers, contacts)
uv run "$SCRIPT" whois google.com
uv run "$SCRIPT" whois kortix.ai

Expiry check

# When does it expire? How many days left?
uv run "$SCRIPT" expiry kortix.ai

Nameservers

uv run "$SCRIPT" nameservers google.com

Bulk check from file

# File with one domain per line
uv run "$SCRIPT" bulk domains.txt

How it works internally

RDAP first -- queries rdap.org/domain/{domain}. HTTP 200 = taken, 404 = available. Returns structured JSON.
whois fallback -- for TLDs without RDAP support, runs whois CLI and pattern-matches response.
Parallel -- uses thread pool (8 workers) for batch checks.
Rate-aware -- bulk mode pauses between batches.

RDAP coverage (1195+ TLDs)

.com, .net, .org, .ai, .dev, .app, .xyz, .tech, .cloud, .gay, .wtf, .bot, .news, .space, .capital, and 1180+ more gTLDs.

whois fallback covers

.io, .co, .me, .sh, .gg, .so, and other ccTLDs that RDAP doesn't support yet.

Rules

No credentials needed. Just run the script.
Present results clearly. Highlight available domains. Show method used (RDAP/whois).
For keyword search, default to common TLDs unless the user specifies otherwise.
For WHOIS lookups, show registrar, dates, status, nameservers. Contacts are often redacted (GDPR).
Rate limits: RDAP has no documented limit but be reasonable. whois registries may throttle after ~50 queries/minute.
Cannot register/buy domains. This is research only. Direct the user to a registrar to purchase.

kortix-voice

kortix-ai/suna

How to work a live voice call from inside a session — start one and share the join link, follow what is being said without blocking, speak into the room, and hang up. The call IS this session, so no call id is ever passed. Load this WHENEVER the user asks to start a call, "call me", talk out loud, or asks anything about the voice channel, and whenever a turn arrives from a live call.

kortix-ai/suna

Canonical reference for a Kortix project: what Kortix can do (research and the web, browser automation, code and data execution, documents and media, websites and apps, connectors/integrations, secrets, memory, scheduling, channels, parallel subagents, model selection) and how the platform works under the hood — repo-native projects, sessions on ephemeral branches, the strict boundary between `kortix.yaml` and OpenCode config under `.kortix/opencode/`; the full `kortix.yaml` manifest (keys, `triggers:` fields incl. cron/webhook/one-off scheduling and `session_mode`, secrets contract, `apps:` deploy surface); the complete `kortix` CLI (commands, flags, the project-scoped token model, the in-sandbox `KORTIX_SANDBOX_TOKEN`); the change-request (CR) system for landing session work on `main` (an agent MUST open a CR to merge); the session sandbox runtime (which supports Docker and Docker-in-Docker); and the OpenCode runtime (agents, skills, commands, tools, plugins, MCP servers, permissions, AGENTS.md rules, model

kortix-ai/suna

Create, manage, validate, preview, and export slide decks and presentations. Build 1920x1080 HTML slide decks (the default, higher-quality path) and export to PDF or PPTX — or produce/edit a fully native, editable PowerPoint (.pptx) file directly when the user needs a plain PowerPoint deliverable. Load this skill when you need to build a slide deck, presentation, or PowerPoint file, or export/edit/validate one.
