description: Attach popular brand prefixes/suffixes to a seed word and check each `.com` via Verisign RDAP. Use when the user names a word and asks for prefix/suffix `.com` variants, or wants domains generated by adding endings like -ly/-ify/-hub or beginnings like open-/get-/go-.

# affix-domains

**Affix** a seed word with common brand prefixes and suffixes, check each `.com` live, and prompt the user to register the free ones.

## Steps

1. **Generate candidates.** For seed `W`, produce `W` + each suffix and each prefix + `W` from the catalog below. Lowercase. Dedupe. Drop any combination that spells an existing English word (e.g. `getup`, `openbox`) — its `.com` is almost certainly taken and burns an RDAP call. If the user hints a style (playful, techy, marketplace…), weight the matching categories; default is every category.

2. **Check `.com` availability** via Verisign RDAP (authoritative for `.com`):
   ```bash
   for d in cand1.com cand2.com ...; do
     code=$(curl -s -o /dev/null -w "%{http_code}" --max-time 10 \
       "https://rdap.verisign.com/com/v1/domain/${d}")
     # 404 = AVAILABLE, 200 = TAKEN
   done
   ```
   For >15 candidates parallelize with `xargs -P 8`. Treat **only 404** as available; anything else means taken or ambiguous.

3. **Surface the survivors** grouped by the catalog category that produced them. One line per free `.com`.

4. **Prompt the user to register.** Ask which they want to take. Point them to Cloudflare Registrar (or their preferred one). Do not enter payment on their behalf — registration is the user's action.

## Rules

- **Live RDAP only** — never claim availability from cached knowledge or prior turns of this conversation. Domains get registered between checks.
- **`.com` only** — this skill's contract. If everything is taken, note that other TLDs are out of scope and offer a companion check.
- **No payment on the user's behalf.** Prompt them to register; they check out.
