architecture-designer

architecture-designer is a skill for Claude Code, Codex from miniidealab/openlogos. It costs 0 tokens per session (2,054 once invoked), scanned A, original, Apache-2.0.

A planning method for defining a software system's overall technical structure before detailed implementation begins. It covers the system boundaries, technology choices, deployment setup, and constraints such as security or performance.

In plain words
What is it for?
Use it to choose a technology stack, plan a system architecture, map services and deployments with diagrams, and update a project's technical-stack record. It is designed to bridge product design and coding.
Why use it?
It reduces inconsistent technical decisions made separately by different implementation tasks. It connects product requirements and user flows to later API, database, frontend, and deployment choices.

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.

Security

Grade A, and why

architecture-designer 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 6d ago.

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.

Skill: Architecture Designer

在逐场景的技术实现之前,建立项目的技术全局视图——系统架构、技术选型、部署拓扑和非功能性约束。确保后续的时序图、API 和代码生成在一致的架构约束下进行。

触发条件

  • 用户要求设计技术架构、做技术选型或规划系统架构
  • 用户提到 "Phase 3 Step 0"、"架构设计"、"技术方案"
  • Phase 2 产品设计文档已完成,需要开始 Phase 3
  • 用户想要确定技术栈或部署方案

核心能力

  1. 读取 Phase 1 需求文档和 Phase 2 产品设计文档,理解产品全貌
  2. 基于产品复杂度和场景特征,推荐适合的系统架构
  3. 为每项技术选型提供选型理由和替代方案对比
  4. 绘制系统架构图(Mermaid)和部署拓扑图
  5. 更新 logos-project.yamltech_stack 字段

与 Phase 1/2 的衔接

架构设计是 Phase 2(产品设计)到 Phase 3(技术实现)的桥梁。它的输入来自 Phase 1/2,输出影响 Phase 3 所有后续步骤:

输入(来自 Phase 1/2) 输出(影响 Phase 3 后续步骤)
场景清单和复杂度 系统边界划分 → 时序图的参与方
非功能性需求(性能、安全) 技术选型约束 → API 设计决策
产品交互方式(Web/Mobile/API) 前端技术栈 → 原型实现方式
数据量和访问模式 数据库选型 → DB 设计
第三方服务依赖(支付、邮件等) 集成方式 → 时序图中的外部参与方

执行步骤

Step 1: 理解产品全貌

读取以下文档,建立对项目的整体认知:

  • 需求文档(Phase 1):产品定位、核心场景、约束与边界
  • 产品设计文档(Phase 2):信息架构、页面结构、交互复杂度
  • 已有的 logos-project.yaml:当前 tech_stack 中是否已有初始选型

重点提取:

  • 核心场景数量和复杂度
  • 是否有实时性需求(WebSocket、SSE)
  • 是否有后台任务(定时任务、消息队列)
  • 第三方服务依赖清单
  • 用户规模预期

Step 2: 确定系统架构

根据产品复杂度选择架构模式:

简单项目(个人 SaaS、工具类产品):

  • 单体架构 + 单数据库
  • 架构概要可以用一段文字 + 一张简图

中等项目(团队 SaaS、多角色系统):

  • 前后端分离 + 单体后端 + 单数据库
  • 可能需要对象存储、缓存等辅助服务

复杂项目(多服务、高并发、多端):

  • 微服务 / 模块化单体
  • 需要详细的架构决策记录(ADR)

用 Mermaid 绘制系统架构图:

graph TB
    subgraph Frontend
        Web[Web App - Next.js]
    end
    subgraph Backend
        API[API Server - Node.js]
        Worker[Background Worker]
    end
    subgraph Data
        DB[(PostgreSQL)]
        Cache[(Redis)]
        S3[Object Storage]
    end
    subgraph External
        Auth[Supabase Auth]
        Email[SendGrid]
    end

    Web -->|REST API| API
    API --> DB
    API --> Cache
    API --> S3
    API --> Auth
    Worker --> DB
    Worker --> Email

Step 3: 技术选型

为每个技术维度给出选型和理由:

| 维度 | 选型 | 理由 | 备选方案 |
|------|------|------|---------|
| 语言 | TypeScript | 前后端统一、类型安全 | Go(性能优先时) |
| 前端框架 | Next.js 15 | SSR + RSC、生态成熟 | Astro(内容站)、Nuxt(Vue 生态) |
| 后端框架 | Hono | 轻量、边缘优先、TS 原生 | Express(生态)、Fastify(性能) |
| 数据库 | PostgreSQL | 功能丰富、JSONB、RLS | MySQL(简单场景) |
| 认证 | Supabase Auth | 开箱即用、RLS 集成 | NextAuth(自托管) |
| 部署 | Vercel + Supabase | 零运维、自动扩容 | AWS(自主控制) |
