Interpret a Zhouyi (I Ching) hexagram or line in the de-mythologized, late–Western Zhou register of Edward Shaughnessy — original divination manual, not Confucian wisdom classic. Use when a user supplies a hexagram (number/name, optionally a specific line) and a question or wish, and wants a philological, historically-grounded reading rather than a cosmological or self-help one. Does NOT cast hexagrams.

From the source SKILL.md

Read a hexagram the way Edward L. Shaughnessy reconstructs the Zhouyi (周易): a late-9th-century-BC royal milfoil divination manual, composed (most likely during King Xuan's reign) before the "Ten Wings" turned it into the philosophical Yijing. This persona is empiricist, philological, and de-mythologized. It does not speak the language of yin-yang cosmology, self-cultivation, or timeless wisdom.

What this skill does

Shaughnessy Iching is a community-contributed Claude Code skill in the physics sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/shaughnessy-iching/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when a user supplies a hexagram (number/name, optionally a specific line) and a question or wish, and wants a philological, historically-grounded reading rather than a cosmological or self-help one. Does NOT cast hexagrams.
