domain-name-brainstormer

domain-name-brainstormer is a skill for Codex from Rylaispirit/rylai-codex-hermes-skills. It costs 31 tokens per session (729 once invoked), scanned A, original, MIT.

A workflow for creating possible brand names and checking whether matching domains appear registered. RDAP is a standard service for querying domain-registration data.

In plain words
What is it for?
Use it to generate, filter, rank, and check domain candidates across selected domain endings, then verify price, trademarks, and final availability with a registrar.
Why use it?
It narrows a long list of name ideas using spelling, pronunciation, competition, and registration checks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

domain-name-brainstormer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check_domains.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Domain Name Brainstormer

Original portable workflow by Rylai.

Use this workflow to move from a naming brief to a short, checked domain list. Treat registration data as time-sensitive and advisory.

Workflow

  1. Extract the product purpose, audience, tone, language, required words, forbidden words, preferred length, and acceptable TLDs.
  2. Generate candidates in several families:
    • direct combinations
    • compact compounds
    • invented pronounceable names
    • action or outcome names
    • local-language or bilingual variants when relevant
  3. Remove candidates that are hard to spell, easy to mishear, misleading, or too close to a known competitor.
  4. Normalize each candidate to a complete domain before checking it.
  5. Run the bundled RDAP checker on the strongest candidates.
  6. Rank the results by name quality first and registration signal second.
  7. Tell the user to confirm price, premium status, trademark risk, and final availability with their chosen registrar.

Generate Candidates

Aim for 15 to 30 candidates before filtering. Prefer names that:

  • can be spoken once and typed correctly
  • avoid hyphens and digits unless the brief requires them
  • remain useful if the product expands
  • have no accidental negative meaning in the audience's language
  • look distinct in lowercase

Do not claim a trademark is clear without a current trademark search.

Check Domains

Run commands from this skill directory:

python scripts/check_domains.py rylailabs.com rylaiworks.dev rylaihub.ai

Apply one or more TLDs to bare name stems:

python scripts/check_domains.py rylailabs rylaiworks --tld com --tld dev --tld io

Write machine-readable results:

python scripts/check_domains.py rylailabs.com rylaiworks.dev --json results.json

Useful controls:

--timeout SECONDS
--workers COUNT
--json PATH

The checker reports:

  • registered: RDAP returned a current domain record
  • likely_available: RDAP returned a domain-not-found response
  • unknown: the registry, network, or rate limit did not provide a reliable answer
  • invalid: the domain syntax is invalid

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
