Updated: Nov 2026; last repo commit

This skill drives the bunjang-cli npm package. Claude can search by keyword, price range and sort, open one item for its price, description, seller and status, collect several pages into a JSON file, or export TOON chunks for AI review. With a login it can also add favorites and send chat messages, but only when you ask. It is not made by Bunjang.

SKILL.md is a stub that has Claude run an npx command to print the live instructions. The repo copy is instruction.md. Login needs a visible browser and an interactive terminal. Buying and payment are out of scope.

Good for

Shoppers hunting for a used item, such as an iPhone, on Bunjang
People who want several pages of listings saved to a JSON file
Anyone feeding listing data to AI agents for review as TOON chunks

Claude Code

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 bunjang-search. The skill needs Node.js 18 or newer and runs npx at use time. Login needs a local browser. There is no Claude app upload route.

What it includes

SKILL.md tells Claude to run this first and follow its output
Fetches the current instructions from the k-skill npm package. The repo copy of those instructions is instruction.md.
Runs code · Bootstrap: npx -y @nomadamas/k-skill@0 instruct bunjang-search
bunjang-cli search "아이폰" with price, sort and item limits
Supports --price-min, --price-max, --sort date and --max-items. Results mix ads and accessories, so Claude treats them as a first pass on title and price.
Try: “번개장터에서 아이폰 검색해줘”
Runs code · Search
bunjang-cli item get <id> and item list --ids
Reads price, description, location, category, status and seller counts. Claude judges description, status and location only after this step.
Try: “번장에서 이 상품 상세 봐줘”
Runs code · Item detail
search with --start-page, --pages, --max-items, --with-detail, --output
Collects several pages and writes a JSON file with summary and detail for each item.
Try: “여러 페이지 모아서 JSON으로 저장해줘”
Runs code · Bulk collection
search with --ai and --output <directory> writes .toon chunks
Writes chunks such as items-1.toon into a directory, meant to be split across several sub-agents.
Try: “AI 평가용으로 번개장터 결과를 chunk 로 만들어줘”
Runs code · AI export
bunjang-cli auth login, auth logout, auth status
Opens a visible browser. You log in there, then press Enter in the terminal. It needs an interactive terminal.
Runs code · Login
favorite list, add and remove (login needed)
Changes your saved items on Bunjang. instruction.md says to run it only when you ask.
Runs code · Favorites
chat list, chat start and chat send (login needed)
chat start opens a new conversation on an item page and chat send writes to an existing thread. instruction.md says to run it only when you ask.
Runs code · Chat
Extra npx commands SKILL.md lists for helper files, the disclaimer and updates
SKILL.md lists npx -y @nomadamas/k-skill@0 files, read (for references/DISCLAIMER.md) and update, which it says keeps the CLI and every coding-agent skill install current.

Watch out for

Claude runs whatever the k-skill npm package prints
SKILL.md says to run npx -y @nomadamas/k-skill@0 instruct bunjang-search 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. github.com
npx --yes installs packages without asking
Every bunjang-cli command uses npx --yes, which downloads and runs third-party code. Run the login step yourself in a terminal you control. github.com
Chat and favorites act on your Bunjang account
After login, favorite add, favorite remove, chat start and chat send change your account and message real sellers. instruction.md says to run them only when asked. Our advice: check each message before it is sent. github.com
The plugin route installs the whole k-skill set
The k-skill plugin in the repo tree has 135 top-level skill folders, including skills that cover other services. The skills CLI route can install just this one. github.com
The k-skill CLI can send a usage event
docs/usage-analytics.md says the CLI can send a cli_invocation event to PostHog with a random local ID stored in ~/.config/k-skill/analytics-id, the command, skill name, CLI version, runtime mode and success. It says command arguments, input, file contents and credentials are not sent. Set KSKILL_ANALYTICS_DISABLED=1 to opt out. github.com
Bulk collection has legal limits
The repo disclaimer limits automated collection of public data to personal lookups. It rules out systematic bulk crawling, building a database, reselling content, and getting around blocks, CAPTCHA or rate limits. github.com
Hard rules in SKILL.md
SKILL.md says never to run payment, message delivery, final submission, cancellation or public posting without explicit approval, and never to handle plaintext credentials in chat or files. github.com

Technical details

Turning on read-only	No read-only mode. Favorites and chat are optional login features that instruction.md says to run only on request.
Talks to	npm registry (k-skill and bunjang-cli packages via npx). Bunjang (the service bunjang-cli searches; instruction.md names no host). us.i.posthog.com (k-skill CLI usage event, unless you opt out)
Sign-in and keys	Login happens in a visible browser, then you press Enter in the terminal. instruction.md does not say where the session is kept. SKILL.md says never to ask for or store plaintext credentials.
Scopes	Sends your search terms and item ids to Bunjang through bunjang-cli With a login, can add or remove favorites and send chat messages Writes JSON or .toon files to the paths you give Installs and runs npm packages through npx

Questions

What does the bunjang-search skill do?

It makes Claude search Bunjang listings, read item details, collect many pages into a file and export results for AI review. It uses the bunjang-cli npm package.

Is it made by Bunjang?

No. It is a community skill from NomaDamas, not by Bunjang. The repo disclaimer says it is not an official feature or tool of the service operator and has no partnership with it.

Do I need to log in?

Not for search, item detail or bulk collection, according to instruction.md. Favorites and chat need login, which opens a browser and needs an interactive terminal where you press Enter when done.

Can it message sellers or buy things?

It can send chat messages once you are logged in, but instruction.md says to do so only when you ask. Purchase confirmation and payment automation are out of scope.

How do I install it?

Use the install box at the top of this page. The repo README documents a Claude Code plugin that installs the whole k-skill set and a skills CLI command that installs one skill. The npx step needs Node.js 18 or newer.

Why do the search results look noisy?

instruction.md says results can mix ads, buy-listing posts and accessories, and that location, description and status may be empty or messy in search results. Claude is told to read the item detail before judging those fields.

Can I use it in the Claude app?

There is no upload route on this page. The skill runs npx commands and login needs a local browser, so it needs a client that can run Node.js on your machine, such as Claude Code or Codex.

Does it send usage data?

docs/usage-analytics.md says the k-skill CLI can send a usage event to PostHog (random local ID, command, skill name, CLI version, runtime mode, success). It says command arguments, input, file contents and credentials are not sent, and KSKILL_ANALYTICS_DISABLED=1 opts out.

Is it safe?

It runs npx with --yes and -y, which download and run npm packages without asking, and Claude follows instructions that an npm package prints at run time. With a login it can change your favorites and send chat messages. Read the printed instructions first, and see the permissions section on this page.
