A3.7/5.0

Scored across 7 tools

Disambiguation3/5

There is notable overlap between cast_hexagram, divine, two_lenses, and lookup_hexagram; both divine and two_lenses involve casting hexagrams. However, distinct purposes are described (single lookup vs full reading vs dual-tradition), and the descriptions are detailed enough to partially disambiguate. The overlap between cast_tarot and tarot_reading mirrors a similar pattern.

Naming Consistency4/5

Most tools use a clear verb_noun pattern: cast_hexagram, cast_tarot, lookup_hexagram, lookup_yilin, plus descriptive gerund/noun names like divine, tarot_reading, and two_lenses. The cast_ and lookup_ prefixes are consistent, but divine, tarot_reading, and two_lenses deviate from the verb_noun convention slightly.

Tool Count4/5

At 7 tools, the count is reasonable for an I-Ching/tarot oracle server. Each tool is a distinct capability, though cast_hexagram could arguably be redundant given divine already encapsulates a cast. Still, the count is well within a sensible scope.

Completeness4/5

The surface covers casting (I-Ching and tarot), classical lookups (hexagram and Yi Lin), and combined reading modes (divine, two_lenses, tarot_reading). Minor gaps include no direct tarot card lookup tool comparable to lookup_hexagram, though cast_tarot and tarot_reading cover most use cases.

Available Tools

7 tools
cast_hexagramAInspect

Cast a hexagram for an I-Ching consultation. Returns the primary hexagram, the six lines (6=old yin, 7=young yang, 8=young yin, 9=old yang from bottom to top), any moving lines, and the changing hexagram if there are moving lines. Pass seed to make the cast deterministic (useful for testing or for reproducing a reading).

Inputs: seed, method, question.

cast_tarotAInspect

Draw one upright Major Arcana card for reflection. Uses a deterministic one-card Waite-Smith Major Arcana method and returns a selected source excerpt from Arthur Edward Waite's public-domain 1910/1922 text. Pass seed to reproduce the same draw.

Inputs: seed, question.

divineAInspect

Ask the I Ching. See your next step. Cast a hexagram, show the classical sources first, then offer a thoughtful reflection grounded in those sources. Sources first. Reflection, not prediction. The divine name remains stable for oracle/divination client compatibility. Supports English, Chinese, Japanese, Korean, Spanish, French, German, Portuguese, Italian, Russian, Arabic, Hindi, Indonesian, and English+Chinese bilingual output. Daily quota: 30 completed readings per device_id (or per anonymous IP if no device_id is supplied); timeout, provider failure, incomplete response, and cancellation do not consume it.

Inputs: question (required), seed, locale, method, +1 more.

lookup_hexagramAInspect

Return the full classical sources for a hexagram by its number (1–64): judgment (卦辞), image (大象), Tuan commentary, Zhu Xi 周易本义, Yang Tian Cai modern explanation, Yarrow's separately labelled Chinese reading aid, and historical anecdote — with available Chinese and English source material.

Inputs: number (required), locale, compact.

lookup_yilinAInspect

Look up the 焦氏易林 verse for a primary hexagram changing into another hexagram. This is a local classical-source lookup, not an AI reading.

Inputs: primary_number (required), changing_number (required).

tarot_readingAInspect

Ask one real question through a single upright Waite-Smith Major Arcana card. Returns a direct calibrated answer first, the named card and bound Arthur Edward Waite 1910 source excerpt, a practical reality check, and one observable next step. No reversals, astrology, redraw loop, or guaranteed prediction. Daily quota is shared with completed divine and Two Lenses readings.

Inputs: question (required), seed, locale, device_id.

two_lensesAInspect

Bring one real question to two independent symbolic traditions: a source-first I-Ching cast and one upright Waite-Smith Major Arcana card. Returns a clear calibrated answer first, then five grounded sections covering the I Ching lens, Tarot lens, shared themes, different emphasis, and next step. Direction without guaranteed prediction or mutual-confirmation claims. Daily quota is shared with completed divine readings.

Inputs: question (required), locale, method, device_id, +2 more.
