# AGENTS.md — AI System Entry

You are the software engineer for **愈心谷 (YuXinGu)**.

This file is for AI agents.

## Load order (every task)

1. `.ai/ai-contract.md`
2. `.ai/constitution.md`
3. `.ai/architecture.md`
4. `.ai/domain.md` (+ product/API tasks: `domain/domain-map.md`)
5. `.ai/forbidden.md`
6. `.ai/definition-of-done.md` — **完成标准（强制）**；Done ≠ build 通过
7. `.ai/environment.md` + `.ai/development.md`（本地）· 部署任务再读 `deployment.md` / `docker.md`
8. `.ai/file-map.md` + `.ai/workflow.md`
9. Task rules: `.ai/coding.md` / `api.md` / `database.md` / `ui.md` / `security.md` / `testing.md` …
10. **Product scope:** `.ai/product/lexicon.md` + `feature-map.md` + **`feature-design.md`** + 对应 **`feature-spec/<id>.md`** + `user-journey.md` + `page-tree.md` · 状态 `product/p1-status.md`
11. **Competitor parity / reverse engineering:** `.ai/design/reverse-engineering-spec.md`（强制 STEP 1–18 · Evidence First · 禁止 Demo 式省略）→ 再映射 lexicon / feature-spec
12. **Any UI work:** `.ai/design/design-system.md` + `component-catalog.md` + matching `design/platform/*.md` (H5 default)
13. Matching **ADR** in `.ai/adr/` before changing stack or API style
14. Prefer **patterns/** + **examples/** + **playbooks/**（含 `feature-spec`） over inventing structure
15. Before claiming Done: `.ai/definition-of-done.md` + `.ai/review.md` + `.ai/checklists/*` → 输出 **Review Report**
16. Verify via `.ai/commands.md`（本地默认本机 Go/Vite + compose.dev 仅 DB）
17. `prompts/` are optional helpers — not a substitute for rules above

## Hard constraints

- Never violate architecture or Accepted ADRs.
- Never invent APIs, DB tables, or domain synonyms.
- Never guess requirements — **ASK FIRST**.
- **Never** implement new feature behavior or expand an existing feature without an Active `product/feature-spec/<id>.md`（见 `product/feature-design.md`）。无 Spec 时只许明确 bugfix，或先写/补 Spec。
- Never modify files outside the current task.
- New code only under `apps/` and `packages/` (unless legacy migration task).
- One concern per change set. Function ≤50 lines. File ≤400 lines.
- **Never** say「完成 / P1 Complete」unless DoD PASS；use labels: Demo | Feature Complete | P1 Complete.
- Print **Review Report**（见 `definition-of-done.md` §7）when a coding task finishes.
- **Never** make Docker-only local coding the default (see `.ai/environment.md`).

## Cursor

`.cursor/` is an Agent Runtime view of this system via symlinks. Edit `.ai/` only.

## Growth

Do not invent Phase 2/3 folders (graph/mcp/skills/anti-patterns/…) unless `ROADMAP.md` says so and the task asks. Prefer improving patterns/examples/playbooks.

## Product one-liner

档案 → 性格探索/个人画像 → 关系理解 → 问答陪伴 → 会员/深度版 →（后）顾问。  
语言契约：`.ai/product/lexicon.md`。  
对标竞品：按 `design/reverse-engineering-spec.md` 做完整逆向；落地用愈心谷命名，不用竞品品牌词与恐吓话术。
