Scored across 39 tools
Most tools have clearly distinct purposes, with the explore_* and ephemeris_* pairs explicitly separated by visual vs raw-data output. A few could be confused (explore_transit_timeline vs ephemeris_transits, explore_bi_wheel modes vs individual return/progression tools), but descriptions handle most ambiguity well.
The naming follows recognizable prefix families (explore_, ephemeris_, auth_, dev_, electional_, acg_), but the internal pattern is mixed: some are verb_noun, some noun_noun, some noun_verb, and some adjective_noun. It is readable and predictable by domain, but not consistent enough for a 4.
At 39 tools, the surface is heavy, and the recurring visual/data duplication (explore_natal_chart vs ephemeris_natal_chart, explore_moon_phase vs ephemeris_moon_phase, etc.) inflates the count beyond what the core domain requires. Even for a multi-tradition astrology API, this exceeds the reasonable 15-25 range.
The tool set covers natal, transits, returns, progressions, synastry, relocation, electional, Vedic, BaZi, Human Design, ACG, moon phases, eclipses, geocoding, and timezone lookup very thoroughly. Minor gaps like a dedicated lunar return or composite chart tool exist, but the generic dev_read_api covers those endpoints as a workaround.
