⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 24, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
Verified the local credential store the skill drives actually works: saved fake keys through jangbu_mcp.credentials, which wrote ~/.jangbu/credentials.env at 0o600 permissions, masked the values in the status readout (abcd...5678), and rejected an unsupported key. Confirmed the BYOK safety claims by reading the source — credentials.py makes zero network calls and codef.py only ever contacts the official CODEF endpoints with the user's own keys. Scored output unmeasured because the real end-to-end task (an actual CODEF connection and Hometax pull) sits behind a free-account signup wall and needs the jangbu MCP server registered in the session, neither of which was available; it is a config guide, so 'setup' is the honest verdict regardless.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 5/10
- Docs & honesty 5/5
What Jangbu Connect does
An interview-style setup guide that walks a Korean user through signing up for the CODEF proxy API and storing their own Client ID/Secret locally (macOS Keychain, falling back to ~/.jangbu/credentials.env) to enable automated Hometax, bank and card data collection. Strictly BYOK: the skill never issues or transmits credentials off-machine. Triggers on requests to connect CODEF or configure automatic collection of Korean tax/financial data.
How to install Jangbu Connect
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.

Frequently asked questions
- Is the Jangbu Connect skill free?
- Yes. The skill itself is free from kimlawtech/korean-jangbu-for. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Jangbu Connect work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 24, 2026. Verdict: Works with setup.

- What is the Jangbu Connect SkillProof Score?
- 8.0/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 5/5.
- How do I install Jangbu Connect?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Jangbu Connect with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
