SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires zod, moment-timezone, moment, tyme4ts, iztro, astronomy-engine, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill provides a fully offline, deterministic engine for calculating complex astrological and metaphysical charts, ensuring that AI agents can provide accurate, sourced readings without relying on unreliable LLM-based math.

Core Features & Use Cases

  • Multi-System Calculation: Computes Western natal charts, Four Pillars (BaZi), and Zi Wei Dou Shu charts with high precision.
  • Evidence-Based Interpretation: Generates sourced readings for career, wealth, and relationships based on traditional rules, not ungrounded predictions.
  • Use Case: When a user asks for a career analysis or a natal chart, the agent uses this Skill to perform the technical calculations and retrieve sourced facts, ensuring the final response is grounded in verifiable data.

Quick Start

Use the calculate-birth-charts skill to generate a full natal chart and career analysis for a birth date of 1990-06-15 at 14:30 in Shanghai.

Frequently Asked Questions about calculate-birth-charts

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I calculate natal charts and BaZi offline without relying on LLM math?▼

You can calculate natal charts and BaZi offline by using a deterministic bundled CLI engine. This ensures astronomical and calendar-based computations are precise, sourced, and do not rely on unreliable LLM-based math.

Can I generate Zi Wei Dou Shu charts with planetary positions and house systems?▼

Yes, you can generate Zi Wei Dou Shu charts alongside Western natal charts and Four Pillars. The engine computes complex metaphysical analysis including precise planetary positions and house systems from birth data.

How do I perform a career analysis from a birth date using deterministic astrology?▼

Provide a birth date, time, and location to the engine to perform career analysis. It calculates the natal chart and retrieves sourced interpretation facts based on traditional astrological rules.

Does this birth chart calculator require an internet connection to compute planetary positions?▼

No, the birth chart calculator operates fully offline. It uses bundled deterministic libraries like astronomy-engine and tyme4ts to perform all astronomical and calendar-based computations locally.

What is the best way to get evidence-based relationship readings from a natal chart?▼

The best way is to use a deterministic calculation engine that generates sourced readings. It retrieves interpretation facts for relationship topics based on verifiable traditional rules rather than ungrounded predictions.

Why use a deterministic CLI for BaZi and Zi Wei Dou Shu calculations instead of standard LLM generation?▼

A deterministic CLI ensures high-precision calculations for BaZi and Zi Wei Dou Shu charts. Standard LLM generation often produces unreliable math, whereas this engine guarantees accurate, sourced metaphysical data.
