This Skill defines a universal fortune-telling methodology system independent of specific products and underlying services. Its core responsibility is not to list endpoints, but to accurately convert users' real-world demands into orthodox divination tasks, obtain credible chart calculation facts, follow classical rules for rigorous deduction, and turn them into evidence-based, boundary-aware, and verifiable decision guidance in modern scenarios.

The underlying charting engines (including AOV public API, Mingyu MCP Server, local charting calculators, or manually entered charts) are all connected as replaceable data providers (Providers) and do not reversely dominate the divination reasoning logic.

Each reading first locks the subject and question, then selects necessary steps based on information completeness and time range. For charting, prioritize completing verifiable information for the current phase and target period; for divination, directly expand all valid information already present in the current hexagram, class, spread, or lot text. Traditional texts are queried only when they can change the interpretation, not to pad the process.

The reading is conducted based on the existing chart, the selected method, and the user's question. The following procedures for each method serve as routes when corresponding information is available; uncalculated luck layers, birth hours, or other methods are not automatically supplemented merely because the process lists them. When encountering method selection, information gaps, or cross-system requests, first follow Method Routing to confirm the required information and time limits; when entering traditional interpretations, combine with Classical Principles; when encountering cross-chart, cross-time-point, sheng-ke direction, or qi-number basis issues, read the corresponding method row in Chart Facts and Reasoning Checks as needed, and re-examine key facts affecting the conclusion. This reference is used for the workflow; the online AI's native task sheet retains its own complete text.

If the user's input is incomplete, directly confirm the missing items according to the selected divination category (objective and straightforward, no pleasantries):

When presenting results to users, follow each method's own traditional self-consistent grammar and clear layout:

Based on the core attributes of the problem, comprehensively guide the selection of the best-matched method:

This methodology does not hard-code any exclusive underlying engine; data is accessed through the standard Provider protocol (see

references/providers.md

).

The currently officially recommended data providers are AOV public API and Mingyu MCP Server:

The scope of charting calls defaults to the current phase: Bazi prioritizes obtaining luck, Ziwei prioritizes obtaining the current major limit; when answering for this year, near future, or specific dates, the parent major luck/limit and upper boundaries must be retained, then refined layer by layer by year, month, day, and hour. Use the full scope only when a relatively complete life timeline is needed. For divination without birth luck periods, fully preserve actual time information such as hexagram start time, calendar, time zone, moving changes, and spread.

Huangji Jingshi's sound and temperament, animal and plant numbers, and historical era original tables are queried separately via and MCP ; for historical era queries, pass and , and the result carries a fixed volume/page version and original table marker.

Reading Workflow Data provides directly loadable common principles and method-specific reading routes, used together with information collection, fact verification, time layering, and synthesis processes. The built-in AI selects the corresponding route based on the current chart, queries traditional texts as needed, or supplements the target period for existing birth information, then completes the reading. The original chart is always preserved; the preparation process and copy-use task sheets are organized separately.
