What problem does it solve?
Korean businesses need to issue electronic tax invoices, statements, cash receipts, and send SMS/KakaoTalk/fax messages through Popbill, but wiring up the SDK, managing secrets, and separating test from production environments is error-prone. This Skill wraps the entire Popbill SDK in a guarded CLI so an AI agent can call any service method safely.
Core Features & Use Cases
- Full Popbill SDK coverage: Exposes taxinvoice, statement, cashbill, message, kakao, fax, closedown, bizinfo, easyfin-bank, account-check, and HomeTax collection services through one generic
call command.
- Safety-gated mutations: Issuing, sending, canceling, or deleting requires an explicit
--yes-i-understand flag, and production mutations additionally require --no-test --allow-production.
- Secret management: Resolves LinkID, SecretKey, and corp number from environment variables, agent vaults, or a permission-checked
~/.config/k-skill/secrets.env file without ever printing secret values.
- Use Case: A freelancer asks the agent to register and issue a test electronic tax invoice; the agent builds the payload from the provided template, gets user approval, and runs the call against the Popbill test environment.
Quick Start
Ask the agent to run the popbill config-check command to verify your Popbill secrets, then request a closedown lookup or a test tax invoice issuance with your approval.
