domain-name-brainstormer — Claude Code skill: name ideas, TLD checks
A skill that generates domain name ideas and checks whether they are free across .com, .io, .dev and .ai.
npx skills add nexu-io/open-design --skill domain-name-brainstormer -a claude-codeWhat domain-name-brainstormer does
It helps at the naming stage: the agent throws out a batch of domain candidates, then checks availability in several zones — .com, .io, .dev, .ai. Handy when the product name isn't settled and clicking through registrars by hand is a chore.
The entry itself is a catalogue record from OpenDesign, curated from the ComposioHQ upstream bundle. There are no scripts or assets here. The full workflow lives in that upstream bundle, so install it into your agent's skills directory. Once installed, invoke the skill by name or with a trigger phrase such as “domain name” or “startup name”.
How the availability check runs and what requests it sends out is not something this record spells out. Worth a look before pointing it at real product names, and check how your platform handles installing bundles from an external repository.
What it helps with
- throw together domain candidates for a new product
- check whether a domain is free in .com, .io, .dev and .ai
- pick a startup name that isn't taken yet
- filter out taken options before buying a domain
Example prompts for the agent
- Brainstorm domain names for a food delivery service and check them in .com and .io
- Use the domain-name-brainstormer skill to suggest 10 options for a product called
orbitand check .dev and .ai - I need free domains for an analytics startup, give me ideas and check availability
