Tools are mostly distinct, with each focusing on specific prayer times (Mincha, Shabbat, Shema, etc.). However, the comprehensive 'daily_times' tool subsumes many of the others, potentially causing an agent to select it instead of a more specific tool.
All tools follow a consistent 'zmanim_get_<descriptive_noun>' pattern in snake_case. This makes it easy for an agent to understand the purpose and predict tool names.
Six tools cover the major categories of Jewish daily prayer times (general, Mincha, Shabbat, Shema, sunrise/sunset, Tefila) without being excessive or sparse. The count is well-scoped for this domain.
The set covers most core daily zmanim needs. However, it lacks tools for holiday-specific times (e.g., Yom Kippur) or fast day times, which would be expected for a comprehensive zmanim server.
