Quick Init Project Skill

Native Subagent Protocol (Codex)

Codex supports native subagents. Delegate with spawn_agent, coordinate with send_input, collect via wait_agent, and clean up with close_agent.

Execution preference:

1. Use native subagents first for independent workstreams (parallel when possible).
2. Merge results in main thread and run final verification.
3. Fallback only when delegation is blocked: use the [ANALYST]/[ARCHITECT]/[EXECUTOR]/[REVIEWER] structure in a single response.

Minimal orchestration pattern:

spawn_agent -> send_input (optional) -> wait_agent -> close_agent

Codex invocation: use $quick-init-project ... or quick-init-project: ...

输入需求后，输出“项目模式决策 + 技术栈 + 目录结构 + 初始化命令”的完整启动方案。

Purpose

用最少信息在 5-10 分钟内完成以下动作：

1. 在 full-stack / frontend-only / backend-only / demo 之间做可解释决策。
2. 优先选择训练数据密集、生态成熟、样例丰富的技术栈。
3. 默认给出 Monorepo + 模块化分层 结构，并在不适合时降级。
4. 输出可直接执行的初始化命令和首批目录结构。

Research Baseline (as of 2026-02-26)

决策默认基于以下公开信号：

• Stack Overflow Developer Survey 2024: Node.js 40.8%, React 39.5%, Next.js 17.9%, NestJS 5.8%
• State of JS 2024: 67% respondents write more TypeScript than JavaScript
• State of CSS 2024: Tailwind CSS usage significantly leads CSS framework category
• npm weekly downloads (2026-02-18 to 2026-02-24):
  • typescript: 131,004,723
  • react: 96,415,450
  • tailwindcss: 60,494,373
  • next: 36,026,759
  • @nestjs/core: 7,290,173

Input Contract

至少提取以下输入；缺失时先按默认值执行并标注假设：

• Product goal: 目标用户与核心场景
• Delivery speed: urgent (<1 week) / normal (2-4 weeks) / long (>4 weeks)
• Team shape: 偏前端 / 偏后端 / 全栈
• Runtime: web / api / both
• Data complexity: low / medium / high

默认假设：normal + 小团队 + web-first + medium complexity。

Mode Selection

Step 1: Hard Gates

按顺序检查，命中即直接选模式：

1. 只做概念演示、验证想法、不要求生产可用 -> demo
2. 后端已存在且 API 契约稳定，只需交付 UI -> frontend-only
3. 前端消费方已存在，只需交付 API/服务 -> backend-only
4. 前后端同时交付且接口会频繁联动 -> 进入打分（通常 full-stack）

Step 2: Weighted Scoring (0-100)

维度打分范围 1-5：

• Requirement complexity (weight 25)
• Delivery speed pressure (weight 20)
• Team skill fitness (weight 20)
• Deployment constraint strength (weight 15)
• Data/state complexity (weight 20)

模式目标画像：

• full-stack: [4, 3, 4, 3, 4]
• frontend-only: [2, 4, 4, 3, 2]
• backend-only: [3, 3, 4, 4, 4]
• demo: [1, 5, 3, 1, 1]

计算：

• fit = 5 - abs(actual - target)
• modeScore = Σ(fit/5 * weight)

决策规则：

1. Top score < 60 -> fallback to demo + 输出信息缺口
2. Top1 - Top2 >= 8 -> 直接选 Top1
3. 差值 < 8 -> 依次比较 delivery speed、team skill fitness、change surface

Tech Stack Policy (Data-Dense First)

Preferred Default Stack

• Language: TypeScript
• Frontend: React + Next.js (App Router) + Tailwind CSS
• Backend: NestJS (REST-first) + OpenAPI
• Package manager: pnpm
• Repository: Monorepo (pnpm workspaces)
• Task orchestration: Turborepo (default), upgrade to Nx when governance is required
• Quality baseline: ESLint + Prettier + Vitest + Playwright

Escalation to Nx

从 Turborepo 升级到 Nx 的触发条件：

• 项目数量 >= 6 个包/应用
• 需要强制模块边界（lint-level boundaries）
• 需要成熟的 affected execution 与更强治理

Downgrade Rules

• 超短期 PoC 且只要可运行页面 -> 可降级到单仓单应用（非 monorepo）
• 后端单服务且无共享包 -> 可暂不启用 monorepo

Architecture Templates

1) full-stack

repo/
  apps/
    web/           # Next.js
    api/           # NestJS
  packages/
    ui/            # React shared components
    config/        # eslint/tsconfig/prettier shared config
    types/         # shared DTO/types
    sdk/           # typed API client
  turbo.json
  pnpm-workspace.yaml
  tsconfig.base.json

Layering rules:

• apps/* can depend on packages/*
• packages/ui cannot depend on apps/*
• packages/types must stay framework-agnostic

2) frontend-only

repo/
  apps/web/
  packages/
    ui/
    config/
    types/

默认使用 MSW 或 mock server 解耦后端可用性。

3) backend-only

repo/
  apps/api/
  packages/
    config/
    types/
    contracts/     # OpenAPI schema + generated clients

默认先交付 OpenAPI 与 health/readiness endpoints。

4) demo

repo/
  apps/demo/
  packages/config/

限制范围：单条主流程 + 最少依赖 + 可快速演示。

Execution Workflow

Phase A: Requirement Parsing

输出 1 屏摘要：

• Problem statement
• Assumptions
• Unknowns

Phase B: Mode Decision

输出：

• Selected Mode
• Scores
• Hard Gate Hit (if any)
• Reasoning (max 3 bullets)
• Risk Note (1 line)

Phase C: Bootstrap Plan

每次都输出：

1. 目录结构
2. 初始化命令
3. 里程碑（Day 1 / Day 3 / Day 7）
4. 最小验证命令（lint/test/build/dev）

Phase D: Command Generation

按模式生成首轮命令。默认命令模板：

pnpm dlx create-turbo@latest
pnpm install
pnpm -r lint
pnpm -r test
pnpm -r build

若 frontend-only 且非 monorepo：

pnpm create next-app@latest web --ts --tailwind --eslint --app
cd web && pnpm test

若 backend-only 且非 monorepo：

pnpm add -g @nestjs/cli
nest new api
cd api && pnpm test

Output Format

每次执行必须返回：

## Init Recommendation
- Selected Mode: <full-stack|frontend-only|backend-only|demo>
- Confidence: <HIGH|MEDIUM|LOW>

## Decision Evidence
- Hard Gate: <rule-id or none>
- Scores: full-stack=<n>, frontend-only=<n>, backend-only=<n>, demo=<n>
- Why: <3 bullets max>

Quality Gates

在宣称“可初始化”之前必须满足：

1. 模式选择有可追踪依据（hard gate 或完整打分）
2. 技术栈包含 TypeScript，且说明为何不是默认栈时的原因
3. 命令可直接执行，不含占位符
4. 目录结构与模式一致
5. 给出至少一个风险与缓解
