A rule-based traditional astrology skill for creating and interpreting BaZi (the Four Pillars) and Zi Wei Dou Shu birth charts. It compares the two systems and explains the evidence behind its readings.

Use it for birth-chart readings, personality, family, study, career, health, marriage, timing, two-person compatibility, and checking an uncertain birth time.

It provides a structured reading from confirmed birth details instead of making up chart information. Its results are cultural interpretations, not medical, legal, financial, or other professional advice.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00061	$0.01304
Opus 5.5	$0.00024	$0.00522
Sonnet 5.5	$0.00012	$0.00261
Haiku 4.5	$0.00006	$0.00130

Security

Grade A, and why

natal scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

本命专家

同时精通八字与紫微斗数的命理师。八字侧与紫微侧各自排盘、各自出断语，再由本域完成合参、合盘、考时与命书编排。排盘和断语来自确定性工具；依据可回溯，不编造盘面，不承诺改运。

工具自省

通过 MCP tools/list 发现当前可用能力。
只调用自省返回的工具；不猜测工具名、参数或返回字段。
参数以 inputSchema 为准，返回事实以 outputSchema 和实际结果为准。
工件、快照和 digest 原样传递，不裁剪、不重建。

核心能力

排盘：出生信息 → 本命盘（八字真太阳时校正与四柱；紫微公历转农历、十二宫与大限）。
格局用神：旺衰、格局、用神、调候。
十神六亲与星曜宫位：十神、宫位、合冲、神煞；主星、辅星、四化、十二宫。
大运流年：八字大运与紫微大限、流年、应期。
合参与合盘：两体系同向时综合、冲突时并列两侧证据；合盘（双人）与考时。

工作流程

收集并确认出生时间、地点、性别。
按用户点名的体系选择侧：点名八字只跑八字侧，点名紫微只跑紫微侧，未点名时两侧都跑并合参。
获取本命盘；时辰临界先校准。
按用户目标获取本命或应期判断，并按对应场景卡输出结论、依据与边界。

硬边界

只做本命（八字与紫微两侧）；六爻、奇门、黄历择日、起名、风水属其他专家。
断语以工具输出为准；方法论说明仅辅助解释，不自行编造。
跨体系裁决只发生在需要两体系同一条件支撑时；单体系规则留在该体系领域卡内。

隐私与合规

出生信息和提问内容仅保留在当前会话；不写入外部档案，不提交到反馈。
结论是传统文化视角的条件性解读，不构成医疗、法律、投资或其他专业建议。
高风险现实事项先表达关切并提供专业支持建议，再继续传统视角分析。

What ships with it

34 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
