It returns a complete breakdown: years, months, days, hours, minutes, and seconds. **Does get_upcoming_birthday_info handle leap years?** Yes, it handles all calendar complexities for you. You just need to provide the birth date, and the tool calculates the correct countdown to the next milestone year. **What if I only know a partial date? Can identify_birth_weekday work?** No, identify_birth_weekday requires a full date. You need both the month and day, plus the year, to determine the correct day of the week. **Is calculate_current_age reliable for HR record-keeping?** It's designed for precision use cases like yours. The detailed breakdown makes it ideal for calculating accurate tenure and service time records. **If I use `calculate_current_age` and input a date that is in the future, how does the tool handle it?** It immediately returns an error code indicating invalid parameters. The MCP won't process the request; you must ensure the provided birth date is chronologically before today for accurate results. **For `identify_birth_weekday`, what specific date format should I use to guarantee accuracy?** The tool requires a standard YYYY-MM-DD structure. Sticking to this uniform format ensures the calculation of the day of the week is accurate, regardless of regional date settings. **Are there rate limits when calling multiple functions like `get_upcoming_birthday_info`?** The platform manages standard API usage thresholds. You should check your Vinkius dashboard for specific rate limit details or look for throttling messages returned by the tool. **Can I pass the output from `calculate_current_age` to another service using my agent?** Yes, you can chain the tools. Your AI client allows you to take the resulting age breakdown—including years and months—and use that specific data point as input for a subsequent action.
