Claude Code plugin that computes East Asian birth charts (Four Pillars, I-Ching) deterministically via lunar-python, then uses Claude only for prose interpretation.
Key Takeaways
Install via /plugin install destiny@destiny-marketplace; birth data collected once, saved to ~/.destiny/profile.json; every subsequent /destiny call is zero-input.
Deterministic layer covers eight-character birth chart, today’s day pillar, five-element/Ten Gods relationships, branch harmonies/clashes, and plum-blossom I-Ching hexagram – all from classical lookup tables and lunar-python.
True solar time correction uses birthplace longitude offset (1 degree = 4 min); Korean DST edge case (1987-88) handled automatically.
Same person + same day always produces identical script output; only Claude’s prose phrasing varies between calls. No external APIs, fully local.
Supports six languages (/destiny in english|korean|japanese|chinese|spanish) and variant commands (today, life, reset, quick, born).
