architecture SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

architecture from dojocodinglabs/code-sensei is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add dojocodinglabs/code-sensei/architecture@git:20260207.d76e1ca

Pins git:20260207.d76e1ca in mdr.lock. Pin the fingerprint instead.

Software architecture, design patterns, and system design concepts. Activated for Blue Belt and above when Claude makes significant architectural decisions.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Architecture — CodeSensei Teaching Module

## What is Architecture?
- **Analogy:** Architecture is the floor plan of your application. Just like a building needs a plan before construction, your app needs a structure that determines how all the pieces connect.
- **Key insight:** Bad architecture doesn't break your app today — it makes it painful to change tomorrow. Good architecture makes change easy.

## Client-Server Architecture
- **The pattern:** Frontend (client) ↔ API ↔ Backend (server) ↔ Database
- **Why this split:** Separation of concerns. The frontend handles display, the backend handles logic and data. They can change independently.
- **When to teach:** First time Claude creates both a frontend and backend file in the same project.

## Monolith vs Microservices
- **Monolith:** Everything in one codebase. Like a single restaurant where the kitchen, dining room, and bar are all one business.
- **Microservices:** Each feature is its own mini-app. Like a food court where each stall is independent.
- **Key insight for vibecoders:** Start monolith. Always. Microservices are for when you have scaling problems, not before.

## MVC Pattern

How to install

The exact contents, by fingerprint

mdr add dojocodinglabs/code-sensei/architecture@sha256:1f68150221abe6aa

The line at the top of this page pins the label git:20260207.d76e1ca, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
