# Design Code Architecture

Settle the decisions you cannot cheaply undo, and defer the rest

## What this does

You are about to start building and cannot tell which structural choices matter now and which can wait. This walks you through boundaries, the domain model, data decisions and resilience, asking questions at each point and saving the answers in your project docs. Reach for it when you want architecture settled before code exists.

### Top 3 things it does for you

- Choose boundaries and a domain model before building
- Decide monolith or microservices
- Work out how this holds up when things fail

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Design Code Architecture

A guided journey from an app idea to a deliberate architecture: boundaries, domain model, data decisions, and resilience, making only the expensive-to-reverse decisions and deferring the rest. It orchestrates eight skills phase by phase: clean-architecture, domain-driven-design, system-design, ddia-systems, software-design-philosophy, release-it, pragmatic-programmer, and 37signals-way.

It asks you questions at every decision point and records the results in your project docs folder, in ARCHITECTURE.md, RELIABILITY.md and DESIGN-CODE-ARCHITECTURE-PLAN.md, so the journey resumes across sessions.

Reach for it when designing a new app's architecture, choosing boundaries and a domain model before building, or deciding monolith versus microservices. If a codebase already exists, remove-technical-debt suits an aged one and improve-code-quality a fresh prototype; if the idea is not validated, run create-business or create-app first. To use one framework on its own, invoke that skill directly.

## Questions

### Is Design Code Architecture safe to install?

AIR scanned this exact version of Design Code Architecture and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit ab2d28a096f4, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/design-code-architecture.

### How do I install Design Code Architecture?

Open https://airmarket.ai/app/design-code-architecture on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/wondelai/skills/tree/ab2d28a096f45e2c0e0ad1a696823db129554bd2/design-code-architecture. Install from that link, not the branch.
