cheap-gas-nearby asks where you are, turns a neighborhood, station or landmark name into coordinates with Kakao Map, then looks up fuel prices from Opinet, the Korea National Oil Corporation's price service. It lists three to five of the cheapest stations with price, distance, address and whether they are self-service. It covers Korea only, and its instructions are written in Korean. The default path goes through a proxy server, so you do not need your own Opinet key.

Good for

Drivers in Korea who want the lowest gasoline or diesel price near them
Anyone who searches by neighborhood, station or landmark name instead of coordinates
k-skill users who want the Korea-focused skill set in Claude Code or Codex

Install cheap-gas-nearby

Claude Code

Copy this prompt.

Install the cheap-gas-nearby skill in Claude Code. Run this command:

/plugin marketplace add NomaDamas/k-skill
/plugin install k-skill@k-skill

Then check that it loaded and tell me how to use it.

Paste it into Claude Code. It shows the change and asks before running it.

Requires Node.js 18 or newer.

Pick one route. The plugin route installs the k-skill plugin, which covers the whole repo: 135 top-level skill folders (counted from the repo tree), with no hooks or MCP config files in the tree. The skills CLI and folder routes install only cheap-gas-nearby. The skill needs Node.js 18 or newer and runs npx at use time, so there is no Claude app upload route.

What's in the skill

When it loads

What it includes

Never guesses where you are
The skill must ask for your current location before any search. It accepts a neighborhood, station name, landmark or latitude and longitude, and asks again if the place is unclear.
Try: “서울역 근처 휘발유 제일 싼 주유소 알려줘.”
Read · Ask for your location first
Turns a name into coordinates
Looks the place up on Kakao Map, skips this step if you give latitude and longitude, and converts WGS84 coordinates to KATEC for Opinet.
Network · Resolve the place with Kakao Map
Radius search sorted cheapest first
Calls the Opinet nearby-stations endpoint with a radius of up to 5000 m, sorted by price. Gasoline (B027) is the default, and diesel (D047) if you say so.
Network · Search Opinet by price
Adds address, phone, self-service and services
Calls the Opinet detail endpoint for the top results to add road address, phone number, self-service, car wash, repair and quality certification.
Network · Fetch station details
3 to 5 stations with price, distance and address
Summarizes the stations with name, price, distance, address, self-service and extras when available.
Read · Short answer
npx -y @nomadamas/k-skill@0 instruct cheap-gas-nearby
SKILL.md says to run this first and follow its output. It also lists helper files with the `files` command and updates with `update`.
Runs code · Fallback to the k-skill CLI

Permissions

High risk

Your location and fuel type go to a server run by the k-skill authors, and the skill runs an npx command first. Use it only if you are fine sharing a neighborhood-level location with those services.

Delete things
Read-only mode

Watch out for

Claude runs whatever the k-skill npm package prints
SKILL.md says to run npx -y @nomadamas/k-skill@0 instruct cheap-gas-nearby and follow its output as the primary instructions. Claude therefore acts on text that comes from an npm package at run time, and the @0 tag floats across 0.x releases, so the instructions can change without any change to SKILL.md. Read the output before Claude acts on it. SKILL.md also lists npx -y ... files and update commands. github.com
Your location goes to a proxy and to Kakao
The default path sends requests through https://k-skill-proxy.nomadamas.org, and place lookups use m.map.kakao.com and place-api.map.kakao.com. The README links a privacy policy for the proxy. github.com
The CLI can send a usage event
The k-skill CLI can send a cli_invocation event to PostHog with a random local ID, the command, skill name, CLI version, runtime mode and success flag. The docs say it does not send command arguments or file contents. Set KSKILL_ANALYTICS_DISABLED=1 to opt out. github.com
The plugin route installs the whole k-skill set
The plugin manifest lists 135 skill folders. Use the skills CLI tab if you want only this skill. github.com

Technical details

Turning on read-only	No read-only mode. The skill only runs lookups, but the stub also runs an npx command.

Scopes	Sends your place name and coordinates to the k-skill proxy and Kakao Map Runs npx -y @nomadamas/k-skill@0 instruct cheap-gas-nearby

Questions

What does cheap-gas-nearby do?

It finds the cheapest gas stations near a place you name in Korea. It uses Kakao Map to locate you and Opinet fuel prices, and shows three to five results with price, distance and address.

Does it work outside Korea?

It is built for Korea. The price source is Opinet, Korea's fuel-price service, and place search uses Kakao Map.

Does it need an API key?

Not for the default path. The instructions say it goes through the k-skill proxy, so you do not prepare an OPINET_API_KEY. If the proxy is down or has no key set, the search fails, which instruction.md lists as a failure mode.

Does it find my location automatically?

SKILL.md says it must ask for your current location first and not guess it. You can answer with a neighborhood, station name, landmark or coordinates.

Which fuels can it search?

Gasoline by default and diesel if you say so. The Opinet product codes in instruction.md also include premium gasoline, kerosene and LPG.

How do I install it?

Use the install box at the top. In Claude Code the plugin installs all of k-skill, while the skills CLI and folder tabs install only this skill. Codex has the skills CLI and folder tabs. You need Node.js 18 or newer for npx. The box has no Claude app upload because the skill runs a command on your machine.

Is it safe?

It runs an npx command from the k-skill package and sends your request to a server run by the k-skill authors. The stub also says never to pay, send messages or submit anything without your approval. See the permissions section.
