Codex plugins do not register Claude-style slash commands. In Codex, the canonical explicit invocation is:
@checkname northstar
@checkname "North Star Labs" --trademark-uspto
If @checkname is present, treat it as an explicit request to use this skill.
Do not fall back to generic repo exploration unless the bundled checker itself
fails or the plugin is not installed/enabled in the current Codex session.
This skill helps an agent answer:
brandname.com likely available?@brandname taken on GitHub, X, Instagram, or YouTube?The goal is fast namespace triage, not legal clearance.
Run the bundled checker with structured output first:
python3 ../../scripts/checkname.py "Candidate Name" --json
You can narrow the scope:
python3 ../../scripts/checkname.py "Candidate Name" \
--variants candidate,candidate-name,getcandidate \
--tlds com,io,ai,org \
--platforms github,x,instagram,youtube,tiktok,bluesky,reddit,linkedin \
--json
If the user wants a human-readable report:
python3 ../../scripts/checkname.py "Candidate Name" --markdown
If the user wants federal trademark triage too:
python3 ../../scripts/checkname.py "Candidate Name" --trademark-uspto --json
That mode should be described as:
taken and available only when the signal is clear.uncertain as unresolved. Do not quietly convert it into available.Return:
