择日功能，根据个人命盘选择适合的吉日良辰
AI agents call select_auspicious_date to retrieve information from Ziwei without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads astrological chart data and returns a recommendation of favorable dates. It does not modify, delete, execute, or involve financial transactions. It is purely a read/query operation that outputs astrological guidance.
From the tool's definition 择日功能，根据个人命盘选择适合的吉日良辰 — selects/recommends auspicious dates based on an astrological chart; this is a query/recommendation operation with no side effects
