AC nts-bizno-cli
Verify Korean business registration numbers (사업자등록번호) via the official NTS (국세청) public API. Operating-status lookup (계속/휴업/폐업), full authenticity check (b_no + 개업일 + 대표자명), local checksum validation without API calls, and bulk file processing. Use when onboarding Korean businesses, validating B2B partners, building KYB pipelines, deduplicating supplier lists, or pre-filling 세금계산서/견적서/계약서 forms with NTS-confirmed data. Pairs with unified-invoice (form fill), opendart-cli (corporate filings), and juso-address-cli (address resolution) to complete the Korean B2B onboarding toolchain.
As a process C 59/100 · Has gaps — weak spots: result and completion, when it triggers, progress reporting
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 59/100
- 0Result and completion. Does not say what the result is
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 50Failures and branches. 0 branches, has a failure section
- 60Tools and files. Uses tools (bash, web) that frontmatter does not declare
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Steps. 24 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1717 tokens
- 100Running it twice. No mutating operations
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
