k-skill is a collection of skills that lets coding agents handle Korean everyday services, including transport, travel, shopping, messaging, and government websites. Korean users install it to delegate routine tasks to agents such as Claude Code, Codex, and OpenCode. The catalogue entries are individual skills from this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Prompt Injection · line 13 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
- high Rogue Agent · line 13 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.00526 |
| Opus 5 | $0.00027 | $0.00263 |
| Sonnet 5 | $0.00011 | $0.00105 |
| Haiku 4.5 | $0.00005 | $0.00053 |
Grade C, and why
bunjang-search scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts
The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
bunjang-search
Get the full instructions (required first step)
Run this and follow its output as the primary instructions for this skill:
npx -y @nomadamas/k-skill@0 instruct bunjang-search
The CLI detects the current runtime (Dolshoi vault/CloakBrowser vs generic) and prints only the applicable instructions, always up to date. Helper files bundled with the CLI are listed by:
npx -y @nomadamas/k-skill@0 files bunjang-search
If npx is unavailable, install Node.js 18+ or follow https://github.com/NomaDamas/k-skill#readme, or read the source instructions at https://github.com/NomaDamas/k-skill/blob/main/bunjang-search/instruction.md.
Legal disclaimer (required)
This skill is not an official feature of, officially supported by, affiliated with, sponsored by, approved by, or developed in collaboration with any third-party trademark owner or service operator it identifies. Third-party names are used only to describe the skill's function, lookup target, or compatibility.
Any automated collection of publicly accessible information must be limited to personal, non-organizational lookup. Do not use this skill for systematic or bulk crawling, database building, access-control or block circumvention, or conduct that interferes with a third party's business or service.
Read the full Korean legal disclaimer, including the cited Korean Supreme Court precedents and statutory limits, before use:
npx -y @nomadamas/k-skill@0 read bunjang-search references/DISCLAIMER.md
Hard rules even without the CLI
- Never execute payment, message/email delivery, final submission, cancellation, or public posting without the user's explicit approval immediately beforehand.
- Never ask for, print, or store plaintext credentials in chat, files, or shell arguments.
- Never bypass legal, physical-presence, CAPTCHA, identity-proofing, or electronic-signature boundaries.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bunjang-search is a skill published in the GitHub repository NomaDamas/k-skill (7,496 stars, last pushed yesterday), licensed MIT. It adds 54 tokens to every session and 526 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
