GitHub user xodn348 released a Claude Code plugin called destiny that returns a daily fortune based on traditional East Asian astrology. After a one‑time prompt for birth date, time, city and gender, users invoke the skill with the /destiny command to receive a personalized reading. The output splits into a short daily forecast with star ratings, a hexagram, and a lucky number, plus a broader life‑arc summary.

The plugin separates deterministic computation from generative prose. A pure‑Python library named lunar-python builds the eight‑character birth chart, the day pillar, and selects the I‑Ching hexagram using plum‑blossom time divination. Those numeric results feed Claude, which crafts the narrative following centuries‑old reading conventions while avoiding hallucinated content. All calculations run locally; no external APIs or scraped data are involved.

By keeping the astrological data verifiable against traditional calendars, destiny sidesteps the common paywall model of many horoscope apps and prevents the LLM from fabricating charts. Developers can install the plugin from the Claude marketplace with a single command and immediately expose users to a culturally rich, language‑agnostic fortune service. The project demonstrates how deterministic domain logic can be paired with large‑language‑model interpretation.
