Jangbu Connect (Grade A) is a security-tested business skill for Claude AI that issues and sets up CODEF API credentials for automatic collection of HomeTax, bank, and credit card data. To use the skill, users must sign up for a free account on CODEF (developer.codef.io) and obtain a Client ID/Secret. The skill saves the Client ID and Secret to a local macOS Keychain or a ~/.jangbu/credentials.env file. This skill follows the BYOK (Bring Your Own Key) principle and does not transmit data to an external server. The skill consists of four steps: obtaining a CODEF account, registering the credentials, confirming the registration, and testing the connection. In Step 1, users must register for a CODEF account, log in, and select the 'My Page' > 'Service Management' > 'New Service Registration' option. They must then select '대한민국' (Korea), '공공' (public), and '금융' (finance) services, and enter the Client ID and Secret copied from the CODEF My Page. In Step 2, users must input the Client ID, Client Secret, and RSA Public Key (optional for production API usage). They can also choose to use a sandbox environment and select whether to save the credentials to the Keychain or an .env file. The skill then calls the codef_credentials_save function to save the credentials. In Step 3, users can confirm the registration by checking the codef_credentials_status response, which displays the credentials status, source, and preview. In Step 4, users can test the connection using the '간편인증 테스트' (simple authentication test) menu. This skill is suitable for individuals who want to collect HomeTax, bank, and credit card data for personal or business use. The skill has a cost guide, with free plans available for personal developers (up to 1,000 requests) and startups (up to 10,000 requests). The skill also provides information on legal indeminity, data storage, and data privacy policies. Users can opt for manual download and import using the jangbu-import flow in case they find the skill difficult to use. Jangbu Connect (Grade A) is a reliable and secure skill for collecting HomeTax, bank, and credit card data, with no external server transmission and a BYOK principle. The skill is suitable for various users, including individuals and startups, and follows Korean public financial API standards.
