No plugin, no config, no setup. Hit Copy for your agent on any example, paste it into Claude Code, Codex, Cursor or zcode, and start chatting. You will have the map you want in five minutes.
The button hands over a brief pointing at llms.txt
— the delta from what your agent already assumes — plus the full
attribute schema, so it stops guessing.
Something bigger? Install the skill once:
npx -y skills add NikaGeospatial/onlymap-js --skill onlymapjs \
--agent claude-code --agent codex --agent cursor --agent zcode
OmMap.validate(html) hands the agent
structured errors, each carrying the fix.
OmMap.snapshotIR(html) shows what the
manifest really resolves to, with no GPU involved.
Agents guess with other map libraries. Here they can verify.
