## Tools (as reported by the server, not verified)

- `cast\_hexagram`: 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
- `lookup\_hexagram`: 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.
- `lookup\_yilin`: 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.
- `cast\_tarot`: 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.
- `divine`: 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, Japan
- `tarot\_reading`: 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 predi
- `two\_lenses`: 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. Dir
