`ownership_card`Which companies a domain depends on, from public records only: registrar with expiry and renewal price (registry RDAP), DNS host (nameservers), website host (A/CNAME and builder verification records), inbox (MX), and services that send mail as the domain (SPF includes, DKIM and bounce records), plus the DMARC policy. Each line shows its evidence. Use for handoffs (“which accounts do I open when it breaks?”), before moving hosts, or to audit a setup. Read-only, no sign-in.

`plan_app_move`An ordered, repeat-safe plan for moving an app built in an AI app builder (Lovable, Bolt, Replit, Base44…) to the user’s own host (Vercel, Netlify, Cloudflare Pages, GitHub Pages) on their domain: export the code, keep the data and sign-ins, deploy and copy environment variables, update auth redirect URLs, add the domain, switch DNS (the builder’s records still live that must go, and the new ones, checked against public DNS), verify, then disconnect the builder. If you can read the project, pass dependency names from package.json and variable NAMES from .env.example: never pass values or secrets. Read-only: it changes nothing. Show the steps and ask before running any command; commands prompt for secret values themselves. Call again after the DNS change to confirm, or use plan_dns_setup.

`plan_dns_setup`The DNS records a domain needs for a website host or AI app builder (Lovable, Bolt, v0, Replit, Base44, Framer, Webflow, Bubble), an inbox provider, and/or the service an app sends email through (SPF, DKIM, DMARC), each checked against live public DNS (in place, missing, or needs change), plus where the domain’s DNS is hosted and records to remove. SPF records from different providers are merged into one. Read-only: it never changes DNS. Use after the user buys a domain, or when their site or email on a custom domain isn’t working.

`plan_launch_steps`The DNS plan for a domain (website host or AI app builder, inbox, app-email service) as ordered, repeat-safe steps with commands the user’s own tools can run: Vercel CLI, Cloudflare’s API with a token from the CLOUDFLARE_API_TOKEN environment variable, Resend’s API with RESEND_API_KEY; a manual list for other DNS hosts. Only records not yet in place get a command, so call it again after each change. Read-only: TLDMath runs nothing. Follow the guardrails in the result: show each change and ask first, never ask for keys in the chat, no deletes without the user naming the record.

`recommend_names`Given a short project description, recommend 3-5 TLDs (best fit first, with reasons) and 10 brandable names, each screened for availability on the top 3 TLDs (or up to 3 the user picks) with the cheapest standard 2-year cost. Optional: a naming style, a word every name must contain (anywhere, at the start or at the end), and a maximum length. Nothing is stored. Run check_domain on a pick for live per-registrar prices.
