# Copilot Instructions - 3D Furniture Workspace

Scope: Entire repository `D:\AI Code\3danzhuang`.

## Mandatory Reading Order
Before coding, always read these files in order:

1. `AGENTS.md`
2. `furniture-3d-system/.cursor/rules/core-standards.mdc`
3. `furniture-3d-system/.cursor/rules/backend.mdc` or `furniture-3d-system/.cursor/rules/frontend.mdc` (pick by task type)
4. `furniture-3d-system/.cursor/rules/checklist.mdc`
5. `furniture-3d-system/docs/设计规范/苹果风格视觉标准.md` (for UI tasks)

## Non-Negotiable Backend Rules
- Enforce architecture: `API Route -> Service -> Repository -> Database`.
- Never put Prisma business queries directly in API routes.
- Use unified request/response helpers: `handleRequest`, `jsonSuccess`, `jsonError`.
- Use unified errors: `AppError + ErrorCode`.

## Non-Negotiable Frontend Rules
- Reuse base UI components from `src/components/ui/` first.
- Follow Apple-style design tokens and visual system.
- Keep brand colors fixed: `#008D74` (light) and `#00B896` (dark).
- Avoid `text-gray-*`, `bg-gray-*`, and raw `<button>`, `<input>`, `<select>` unless explicitly required.

## Working Directory
- If user does not specify, default to `furniture-3d-system`.

## Delivery Gate
Before final response, include:
- Changed file list
- Validation commands executed
- Validation results

## Execution Policy
- Do not optimize for "minimal changes" by default.
- Prefer complete, verifiable fixes for the full task chain.
