freee-api-skill 是做什么的？
A skill that integrates with freee-mcp / freee-sign-mcp, providing detailed API references and usage guides for accounting, HR/payroll, invoicing, project time tracking, sales, IT management, and electronic signatures (e-contracts). Use this skill when you need to look up operations or API specifications related to freee features such as expense applications, transaction registration, attendance time stamps, pay slips, quotes, trial balances, journal entries, employee management, time entry, sales data management, SaaS account management, equipment management, and e-contract document management. If a user asks about data manipulation, accounting, HR/payroll, invoicing/quotes, project time tracking, sales, IT management, or electronic contracts—even without explicitly mentioning "freee"—consider using this skill. The electronic signature feature requires separate configuration of freee-sign-mcp.
