Agent readability score
Strengths
- Tool names clearly indicate their primary function (e.g., 'solar_to_lunar' for date conversion).
- Parameters are explicitly defined with required fields and data types.
Weaknesses
- Descriptions focus on 'what' the tool does rather than 'when' to use it (e.g., 'supports 2025/2026' without explaining use cases).
- Potential overlap between 'query_holiday' and 'list_holidays' for holiday-related queries.
- No explicit documentation of error handling or constraints (e.g., invalid date ranges).
query_holiday— Description does not clarify if it returns only specific date info or full holiday schedules.list_holidays— Overlaps with 'query_holiday' in holiday-related functionality without clear differentiation.solar_to_lunar— Description lacks context on whether it handles date validation or edge cases (e.g., invalid lunar dates).
