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
-
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.
-
Check .com availability via Verisign RDAP (authoritative for .com):
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.
-
Surface the survivors grouped by the catalog category that produced them. One line per free .com.
-
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.
