 - `prompts/` — 9 numbered interview prompts (01-09) that guide AI to interview users and generate structured context documents. Topics: personal values, career, entrepreneurship, daily life, social relationships, family, annual goals, finances, AI interaction preferences.
 - `templates/` — Supporting tools: a privacy classification guide (隐私分级指南), a fill-in-the-blank profile template (档案模板), and a usage guide (使用指南).
-- `examples/` — Example outputs (currently empty).
+- `examples/` — Example outputs (currently empty). User-generated vault files go in `my-vault/` (not tracked here).
 
 ## Content Conventions
 
 - All content is written in Simplified Chinese.
-- Prompts follow a consistent structure: role setup, interview methodology instructions, topic-specific questions, and output format requirements.
-- Files are numbered (01-09) to indicate a suggested completion order.
+- Each prompt in `prompts/` follows a 4-part structure: (1) role setup for the AI interviewer, (2) interview methodology instructions (深度访谈 style — push back on vague answers), (3) topic-specific questions grouped by theme, (4) output format requirements for the resulting context document.
+- Files are numbered (01-09) to indicate a suggested completion order. Prompt 01 (个人宪法) is the foundation and should be completed first.
 - Privacy-sensitive placeholders use `[已脱敏]` format.
 - The project differentiates from the English original by covering China-specific topics: 体制内/外 career paths, 原生家庭 dynamics, 房贷/教育支出 financial concerns.

+## Prompt Combinations (from README)
+
+Prompts are designed to be combined when loaded into an AI conversation:
+
+- **求职/跳槽** → 01 + 02 + 07
+- **创业决策** → 01 + 03 + 08
+- **生活规划** → 01 + 04 + 06 + 07
+- **人际关系** → 01 + 05 + 06
+- **理财建议** → 01 + 08 + 07
+- **任何对话** → 01 + 09 (recommended every time)
