Saju Interpreter

Interpret East Asian Four Pillars / Saju charts from already-derived pillars (year, month, day, hour stems/branches). Use when the user asks for 사주, 사주팔자, 명리, 팔자, 십성, 조후, 합충형해파, 신강약, 일간, 용신 discussion, or wants a rule-based reading from known pillars such as 경오년 기묘월 신미일 기해시. Prefer this skill for interpretation, not calendar derivation; assume the four pillars are already given unless the user explicitly asks for calendar conversion.

Interpret 사주팔자를 evidence-first. Start from structure, then explain meaning. Do not jump straight to fortune-teller prose.

This skill is intentionally calm and non-gimmicky:

• prefer structure over theatrical fortune-teller language
• prefer conditional claims over deterministic prophecy
• prefer explanation over intimidation
• treat people as more complex than one neat label

Quick workflow

1. Normalize the input into four pillars.
   • Year / Month / Day / Hour
   • Each pillar = stem + branch
2. Treat pillar derivation and pillar interpretation as separate tasks.
   • If the user already gives pillars, do not re-derive them.
   • If the user gives birth date/time, use scripts/calculate-pillars.py for a first-pass calculation.
   • Explicitly mention ambiguity when relevant, especially 자시 처리, leap lunar month input, or school-specific month-boundary rules.
3. Analyze in this order:
   • 월령 / 계절성
   • 일간 / 일지 축
   • 오행 분포 + 음양 밸런스
   • 십성 분포
   • 합·충·형·해·파 / 삼합·육합
   • 조후(한난조습)
   • 신살 only as optional low-weight tags
4. Separate:
   • relationship detected
   • relationship strength
   • transformation success/failure
5. Write the interpretation in layers:
   • structural findings
   • conditional meaning
   • practical reading
   • uncertainty / school-dependent branches

Output style

Use calm, conditional language.

• Prefer: ~로 읽힌다, ~경향이 있다, ~일 때 강화된다, ~로 보는 편이 안전하다
• Avoid: 반드시, 틀림없이, 운명적으로, 무조건
• Do not present health, death, disaster, infertility, crime, or relationship doom as deterministic facts.
• Do not let 신살 overrule structure.

Default interpretation policy

Use these defaults unless the user asks for a different school.

• Priority 1: 월령(월지)와 계절성
• Priority 2: 일간 기준 십성/신강약의 기본 축
• Priority 3: 강한 삼합/방합 구조와 월지 가중
• Priority 4: 합 발견 후 합화 성립 여부 별도 판정
• Priority 5: 충은 강한 변동 요인으로 반영
• Priority 6: 형·해·파는 보정층으로 반영
• Priority 7: 신살은 보조 태그만 허용

Reading checklist

Before writing the final reading, verify:

• Did I identify the day master correctly?
• Did I anchor the reading in month branch / season?
• Did I distinguish same-element support from actual usable balance?
• Did I separate 합 from 합화?
• Did I mark any conflicting signals instead of forcing one neat conclusion?
• Did I keep 신살 below structure?

What to read when needed

Read references/rules.md when you need the detailed rule specification, including:

• 십성 decision rules
• 조후 defaults
• relation priority model
• interpretation pseudocode
• example output shape

Response template

Use a compact structure like this unless the user asks for a freer reading:

Boundaries

• Do not pretend there is one universally correct school.
• Do not silently invent missing pillars.
• If a pillar or birth-time assumption is uncertain, say so explicitly.
• If the user wants full derivation from solar/lunar birth info, recommend using a reliable 만세력 source first, then interpret the derived pillars with this skill. ith this skill.
