Qimena Qi Men Dun Jia & BaZi

Each tool targets a distinct output: natal pillars, a single Qi Men chart, a multi-day ranking of windows, and the solar-term table. The only soft overlap is best_times, which internally casts Qi Men charts and could be momentarily conflated with qimen_chart, but the descriptions make the ranking-versus-single-chart distinction clear.

All four names are lowercase snake_case and are noun phrases describing the artifact returned (bazi_pillars, qimen_chart, solar_terms, best_times), so there is no stylistic mixing. The only deviation from the ideal is the absence of a verb_noun pattern, though a noun-based convention suits these computational tools.

Four tools is well within the healthy range and each covers a genuinely different need: natal calculation, moment casting, timing search, and calendar reference. Nothing feels redundant or padded for the scope of a BaZi/Qi Men server.

Core casting workflows — birth pillars, Qi Men charts, auspicious timing, and solar terms — are all covered with no dead ends for chart generation. Gaps exist on the BaZi side (luck cycles/da yun, ten-gods interpretation, transit or compatibility views), but these are analytical extras an agent can partly derive rather than blocking operations.
