Each tool targets a distinct analysis layer: raw natal chart, calendar lookup, element distribution, hot/cold climate, classical structure, and yongshin candidates. Any apparent overlap, such as saju_chart's five-element ratios or yongshin_candidates drawing on eumyang_johu/gyeokguk, is clearly differentiated by the descriptions and intended use cases.

All tool names are lowercase snake_case and mostly follow a romanized-Korean plus English-descriptor pattern, as seen in manse_calendar, ohaeng_balance, saju_chart, and yongshin_candidates. eumyang_johu and gyeokguk are pure romanized terms without an English suffix, which is a minor deviation but still not confusing.

Six tools is a well-scoped size for a saju-analysis server. Each tool covers a distinct facet of the domain—chart, calendar, five elements, climate, structure, and favorable elements—without unnecessary redundancy.

The set covers the core Four Pillars workflow: natal chart construction, calendar lookup, five-element balance, johu, gyeokguk, and yongshin candidates. The main gaps are the lack of a tool that resolves yongshin candidates into a single final decision and the absence of a dedicated daeun/sewoon fortune-cycle tool, though these seem like deliberate scope limits rather than critical omissions.
