xiaoliuren · Xiao Liu Ren divination (dsh-plugin-xiaoliuren)

A Xiao Liu Ren (小六壬) divination project: cast a reading via time / numbers / random, and get a conclusion-first plain-language verdict plus the six-palace layout, auspiciousness, five elements, direction, celestial spirit and verse. It works standalone (library + CLI) and also ships as a DeepSeek Harness (DSH) tool plugin (tool name xiaoliuren). Every result carries a disclaimer — entertainment/traditional-culture reference only.

Features

• Three casting modes: time (solar/lunar), numbers (1–3 numbers), random (seeded & reproducible)
• Conclusion-first: plain-language verdict + advice, then layout details
• question is echoed in the conclusion and never affects the math
• Configurable: calendar, lateZiShiRollover, disclaimer text, random source
• Zero-dependency core (src/core/ is pure functions; lunar calendar uses a built-in compact table)
• Install-and-run: committed lib/ output, loaded by DSH via main: lib/index.js

Build & test

pnpm install
pnpm typecheck
pnpm test
pnpm build

Requires Node ≥ 18 (Node 22 recommended) and pnpm.

Library usage

import { castTime, castNumbers, castRandom } from 'dsh-plugin-xiaoliuren'

const r = castNumbers([3, 15, 5])                                  // numbers: month=3, day=15, hour=5
const r2 = castTime('2024-02-10T12:00:00', { calendar: 'lunar' })  // lunar time casting
const r3 = castRandom({ randomSource: { seed: 42 } })              // reproducible random

Public API: castTime, castNumbers, castRandom, compute, advance, renderSteps, getPalace, PALACES, shichenFromHour, shichenName, solarToLunar, makeRng, and all types.

CLI usage

xiaoliuren
xiaoliuren time --datetime 2024-02-10T12:00:00 --question "Will this project succeed?"
xiaoliuren time --calendar lunar
xiaoliuren numbers 3 15 5
xiaoliuren random --seed 42 --json

Invalid input prints a Chinese error and exits non-zero. Default output is the conclusion-first card:

【小六壬】结果
所问：Will this project succeed?
起卦：报数（3·15·5）→ 小吉
结论：所问之事大吉，成功可期，诸事顺遂 —— 宜积极行动，趁势而为。

The six palaces

All palace data lives in src/core/palaces.ts (data-as-config): adjust it for school differences, never the algorithm.

Math

• Fixed order: 大安(1) → 留连(2) → 速喜(3) → 赤口(4) → 小吉(5) → 空亡(6).
• Count months from 大安, days from the month result, hours from the day result; each step counts the current palace as 1 and steps (n−1) forward with modulo 6 wrap.
• Equivalent formula: finalIndex = ((month + day + hour - 3) % 6) + 1.
• Shichen mapping: ordinal = floor(((hour + 1) % 24) / 2) + 1, 子1 … 亥12, 23:00 wraps to 子.

Calendar & late-zi rollover

• Lunar: castTime(date, { calendar: 'lunar' }) uses the built-in 1900–2100 compact lunar table (solarToLunar; source/scope noted in src/core/time.ts). No third-party lunar/date runtime library.
• lateZiShiRollover (default false): whether 23:00–23:59 counts as the next day with day+1. v0.1 defaults to no rollover; enabling it advances the day (month/year carry handled by Date).

Quick install (one command)

Load the plugin into a DSH profile with the bundled installer:

powershell -ExecutionPolicy Bypass -File scripts\install-dsh.ps1            # web profile, GitHub source
powershell -ExecutionPolicy Bypass -File scripts\install-dsh.ps1 -Profile headless
powershell -ExecutionPolicy Bypass -File scripts\install-dsh.ps1 -Source file:C:\path\to\xiaoliuren

The script runs dsh plugin --profile <p> add <source> and idempotently appends the tool-xiaoliuren insert row to the profile's cordis.patch.yml. Restart dsh web afterwards.

Install shortcuts & restart requirement

• Fully restart dsh web (stop the process, then start it again). A browser refresh is NOT enough. The client-plugin graph is composed and cached at server boot (package metadata is cached per name and never expires); only a restart re-scans installed package.json files and serves /plugins/<pkg>/client.js for packages declaring exports["./client"] + dsh.client. The host-side xiaoliuren tool loads immediately; the widget is client-side and needs the restart. Sessions persist in ~/.dsh/sessions, so the restart does not lose conversations.
• One-command install (idempotent): powershell -ExecutionPolicy Bypass -File scripts\install-dsh.ps1 (options: -Profile, -Source file:C:\..., -SkipInstall). The script is Windows PowerShell; macOS/Linux users can follow the three-step manual install below (full restart still required).
• Offline / network-fallback shortcut: dsh plugin --profile web add file:E:\AI\xiaoliuren. Git deps pin a commit, so after code updates run dsh plugin --profile web update dsh-plugin-xiaoliuren (or reinstall) and restart.
• Verify after restart: host tool via dsh --profile web --dump-config | grep -i xiaoliuren; widget via http://127.0.0.1:3080/plugins/dsh-plugin-xiaoliuren/client.js → expect 200 (404 = not restarted / not discovered); the boot manifest window.__DSH_BOOT__ should list dsh-plugin-xiaoliuren.

Widget (client UI)

The package also ships a browser-side widget: a small 卦 button pinned to the app's top-right corner (always visible — even in a brand-new empty session) that collapses into a dot and expands into a panel — pick 数字 / 时间 / 随机, type the 事由 (matter), hit 生成, and get the conclusion-first result card with the disclaimer. It lives in lib/client.js and auto-loads once the package is installed and dsh web is restarted.

DSH integration (three steps)

dsh plugin --profile web add github:shuimo07/xiaoliuren

# then append to the profile's cordis.patch.yml:
#   - insert:
#       - id: xiaoliuren
#         name: 'dsh-plugin-xiaoliuren'
#         config: { calendar: solar, randomSource: crypto }

dsh --profile web --dump-config | grep -i xiaoliuren   # verify

The plugin exports { name: 'tool-xiaoliuren', inject: ['tools', 'systemPrompt'], Config, apply } and registers the xiaoliuren tool (parameters: mode, numbers, datetime, calendar, question; output follows the CastResult JSON schema; render is the conclusion-first text card). Plugin config: calendar (solar/lunar), randomSource (crypto/math), disclaimer (text).
