Polish Company Verification as a Claude Skill

说明与用途

作者为 Claude Code 创建了一个技能，用于自动化波兰公司验证。它使用 skanfirmy.pl API 检查增值税状态、银行账户和政府登记数据，无需 API 密钥。

问题

Verifying Polish companies (VAT status, bank account whitelist, court register data) requires checking multiple government sources, which is time-consuming and error-prone when done manually or via ad-hoc prompts.

结果

A reusable, keyless Agent Skill that enables Claude to verify Polish company details (VAT, Bank Whitelist, KRS, REGON) and EU VAT numbers automatically, reducing manual lookup time and ensuring correct endpoint selection.

工作流

• Clone the skanfirmy-mcp repository from GitHub.
• Create the ~/.claude/skills directory if it does not exist.
• Copy the 'skill' folder from the repository to ~/.claude/skills/verify-polish-company.
• Restart Claude Code to load the new skill.
• Ask Claude in plain language to verify a company (e.g., 'is NIP 5260250995 an active VAT payer?').
• Claude automatically executes the appropriate GET request to skanfirmy.pl and returns the verification results.

证据

A Skill is just a folder with a SKILL.md file... Claude reads the description, and when a task matches, it loads the body and follows it.

No API key, no signup, nothing to run beyond ordinary HTTP.

The data comes straight from official sources: the Ministry of Finance for the VAT white list, the Ministry of Justice for the court register, the statistics office (GUS) for REGON, and the European Commission for VIES.
