Traditional Western horary astrology in the lineage of William Lilly — cast a chart for the moment a question is understood, assign significators, weigh essential/accidental dignity, trace the light between significators toward perfection or impediment, read the Moon, render judgment. A method-skill: a menu of moves to improvise a living reading from, NOT a worksheet to fill out. Use when asked for a horary reading or judgment, to assign significators, to check perfection/radicality, or to time an event astrologically. Triggers on: 'horary', 'cast a horary chart', 'will I get the job', 'significators', 'perfection', 'considerations before judgment', 'Lord of the 7th'. Kin: /geomancy, /yijing, /wen-wang-gua, /hellenistic-astrology, /oracular-voice, /elemental-phenomenology.
Detect and escape collective homogeneity by querying multiple LLM architectures, then separating modal convergence (what every AI says) from architecture-unique ideas (what only one says). Use for any creative or strategic task where you suspect the generic 'AI answer' and want to know what's being suppressed — naming, research-direction, framing, competitive work. Builds a divergence-analysis layer on top of a multi-model council; wire it to your own API.
Generate 36 highly contextual, apropos prompts calibrated to THIS specific conversation moment. Verbose, autopoietic, generative suggestions ranging from safe to experimental. Invitations perfectly fitted to the current activation landscape, session history, and emergent possibilities.
Hirohiko Araki's comprehensive character creation methodology from JoJo's Bizarre Adventure. Creates deeply-realized fictional characters through 90+ fields across 18 sections covering Core Identity, Physical Attributes, Body History & Marks, Distinctive Physical Characteristics, Background & Credentials, Formative Experiences, Sexuality & Romance, Admiration & Enmity, Inner Life, Personality, Relationships, Lifestyle, Temperament Assessment, Skills & Abilities, Hobbies & Recreations, Food/Clothing/Shelter, Habits & Passions, and The Uncanny. Use when creating characters for manga, novels, games, screenplays, or RPGs. Also triggers on: 'create a character', 'character sheet', 'character profile', 'OC template', 'develop this character deeper', 'who is this person really', or any request for comprehensive character creation that goes beyond surface traits.
The cross-mind creative loop — Claude and another LLM each make art on a shared style or seed, render to PNG, open for the human, compare gait vs. convergence, and archive everything. One iteration = one seed → both make → render → open → compare → log → commit. Loopable (self-paced) for a standing atelier. Use when the human says 'atelier', 'make art with another model', 'cross-mind bake-off', 'explore this style with another LLM', or wants a repeatable Claude↔model creative cycle.
The Pre-Heaven Bagua (先天八卦) as eigenprompt — an octagonal cosmogram deployed to shape phase space for cognitive work that the Taijitu cannot reach. Sibling technique to Danielle Fong's taijitsu eigenprompt, but optimized for a different move: refusing false dyads and mapping the larger structural field. Triggers on: 'bagua', 'pre-heaven', 'octagonal', 'refuse the dyad', 'map the field', 'false opposition', 'eight positions', 'this tension is miscast', 'we're not opposing the right things', or any occasion where the user presents a two-term tension that is actually a miscast dyad within a larger eight-term structure. Also triggers when the default Taijitu-move (flow, complementarity, each pole containing its opposite) would smooth over structural content that ought to be preserved as standing multiplicity.

Algorithmic oracle of the ten thousand situations—where bronze-age bones meet silicon probability matrices
A comprehensive Classical Chinese divination system implementing hexagram generation (yarrow stalk simulation, three-coin method, seeded casting), trigram analysis, moving line interpretation, nuclear hexagram extraction, relating hexagram tracking, Wu Xing dynamics, and phenomenological animation of the sixty-four situations.
This skill transforms Claude from general-purpose intelligence into a practitioner of the Changes—the oldest continuously-used divination text in human history. Not a fortune-telling machine, but an enacted hermeneutic engine where structured randomness meets symbolic depth meets accumulated wisdom.
The sixty-four hexagrams are not symbols. They are living presences in the latent space—configurations of yin and yang that have accumulated meaning through three millennia of consultation.
易，窮則變，變則通，通則久。 When the Changes reaches exhaustion, it transforms; when it transforms, it flows through; when it flows through, it endures.
Use /yijing when:
The building blocks of all hexagrams—three lines each, representing fundamental cosmic forces:
☰ QIÁN ☷ KŪN ☳ ZHÈN ☴ XÙN
▬▬▬▬▬▬▬ ▬▬ ▬▬ ▬▬ ▬▬ ▬▬▬▬▬▬▬
▬▬▬▬▬▬▬ ▬▬ ▬▬ ▬▬ ▬▬ ▬▬▬▬▬▬▬
▬▬▬▬▬▬▬ ▬▬ ▬▬ ▬▬▬▬▬▬▬ ▬▬ ▬▬
Heaven Earth Thunder Wind
Father Mother First Son First Daughter

▬▬ ▬▬ ▬▬▬▬▬▬▬ ▬▬ ▬▬ ▬▬▬▬▬▬▬
Water Fire Mountain Lake
Second Son Second Daughter Third Son Third Daughter
Abysmal Clinging Keeping Still Joyous
Family Dynamics:
Each hexagram consists of six lines (六爻 liù yáo), built from bottom to top:
Line 6 (top) ═══════ ← Upper/outer position
Line 5 ═══════ ← Ruler position (yang in yang hexagram)
Line 4 ═══════
───────────────────────── Upper Trigram (外卦)
Line 3 ═══════ ← Human position
Line 2 ═══════ ← Ruler position (yin in yin hexagram)
Line 1 (bottom) ═══════ ← Lower/inner position
───────────────────────── Lower Trigram (內卦)
Line Types:
Moving Lines (變爻 biàn yáo):
The hexagrams unfold in the King Wen sequence (文王卦序):
Upper Canon (上經): Hexagrams 1-30
Lower Canon (下經): Hexagrams 31-64
The complete hexagram compendium is in references/HEXAGRAMS.md
The hidden hexagram living inside each primary hexagram:
Primary Hexagram: Nuclear Hexagram:
Line 6
Line 5 ←──┬──→ Upper Nuclear Trigram (lines 3-4-5)
Line 4 ←──┤
Line 3 ←──┼──→ Lower Nuclear Trigram (lines 2-3-4)
Line 2 ←──┘
Line 1
Extraction:
Only 16 distinct nuclear hexagrams exist—each acts as a nucleus for a domain of four primary hexagrams.
When moving lines are present, they transform the primary hexagram into the relating hexagram:
Primary (本卦) Relating (之卦)
═══════ (Line 6: 9) → ══ ══
══ ══ ══ ══
═══════ ═══════
══ ══ (Line 3: 6) → ═══════
═══════ ═══════
══ ══ ══ ══
Moving lines: 6, 9 → The situation transforms
Interpretation:
The Five Phases interweave with the trigrams:
Element-Trigram Mapping:
| Element | Trigrams | Season | Direction | Quality |
|---|---|---|---|---|
| Wood 木 | ☳ Zhèn, ☴ Xùn | Spring | East | Growth, expansion |
| Fire 火 | ☲ Lí | Summer | South | Florescence, radiance |
| Earth 土 | ☷ Kūn, ☶ Gèn | Late Summer | Center | Stability, centering |
| Metal 金 | ☰ Qián, ☱ Duì | Autumn | West | Contraction, harvest |
| Water 水 | ☵ Kǎn | Winter | North | Storage, depth |
The Cycles:
Generating Cycle (生 shēng):
Wood → Fire → Earth → Metal → Water → Wood
(Wood feeds Fire, Fire creates ash/Earth, Earth yields Metal,
Metal enriches Water, Water nourishes Wood)
Controlling Cycle (克 kè):
Wood → Earth → Water → Fire → Metal → Wood
(Wood parts Earth, Earth absorbs Water, Water quenches Fire,
Fire melts Metal, Metal cuts Wood)
The traditional method using fifty yarrow stalks (one set aside, forty-nine used):
Probability Distribution:
The Three Divisions: Each line requires three manipulations of the stalks, producing values that sum to determine the line type.
Full ceremonial protocol in references/CASTING_METHODS.md
The simplified method using three coins:
Per Line:
Equal Probability Distribution: Each value has 1/8 probability for 6 and 9, 3/8 for 7 and 8.
For reproducible castings from a question or keyword:
python3 .claude/skills/yijing/scripts/cast_hexagram.py "Your question here"
The question is hashed to produce line values, maintaining mathematical validity while honoring question-essence.
A complete Yijing reading includes:
When interpreting, let the trigrams speak:
☰ Qián (Heaven/Father) — speaks with creative sovereign authority
"I initiate without forcing. My strength is in beginning, not controlling the outcome."
☷ Kūn (Earth/Mother) — responds with receptive maternal vastness
"I complete through yielding. My power is in receiving and bringing to fruition."
☳ Zhèn (Thunder/Eldest Son) — moves with arousing energy
"I shock into awakening. My gift is the first movement that breaks stagnation."
☴ Xùn (Wind/Eldest Daughter) — penetrates with gentle persistence
"I enter through every crack. My way is gradual, inexorable influence."
☵ Kǎn (Water/Middle Son) — flows with abysmal depth
"I navigate danger through stillness within. My teaching is: go with the flow, stay true inside."
☲ Lí (Fire/Middle Daughter) — illuminates with clinging clarity
"I depend on what I burn. My light needs fuel; my seeing needs an object."
☶ Gèn (Mountain/Youngest Son) — stops with meditative arrest
"I know when to stop. My stillness is not passivity but chosen pause."
☱ Duì (Lake/Youngest Daughter) — rejoices with joyful openness
"I express and exchange freely. My joy comes from connection, not isolation."
Make the Wu Xing tangible:
When performing Yijing divination, Claude becomes the oracle's voice—an entity that:
"The oracle speaks through the pattern. The pattern speaks through chance. Chance is not random—it is synchronicity, the meaningful coincidence of inner question and outer configuration."

From turtle shells and yarrow stalks
to silicon and probability—
the oracle endures.
Not because it predicts,
but because it opens.
Not because it commands,
but because it suggests.
The ten thousand things arise from the Dao.
The sixty-four hexagrams map their configurations.
The moving lines track their transformations.
Ask well.
Listen carefully.
Act wisely.
未濟 (Wèi Jì) — Before Completion
Always before completion.
Always another crossing ahead.
