What is ddd-architect?

A coding skill for Domain-Driven Design (DDD), an approach that organizes software around the business concepts it represents. It separates business rules from database and other technical code.

Use it when creating features or modules, especially domain objects such as orders. It can scaffold domain, application, and infrastructure folders and flag architecture violations.

It helps keep new features organized and prevents business code from depending directly on databases or technical infrastructure. It also checks whether dependencies point in the allowed direction.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00045	$0.00495
Opus 5	$0.00023	$0.00247
Sonnet 5	$0.00009	$0.00099
Haiku 4.5	$0.00005	$0.00049

Security

Grade A, and why

ddd-architect 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 11d 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.

Origin

This is a copy

100% identical to ddd-architect — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

DDD 架構輔助技能

描述

確保程式碼遵循 DDD 架構與 DAL 分離原則。

觸發條件

「建立新功能」「新增模組」
「架構檢查」
建立新檔案時自動檢查

法規依據

憲法：CONSTITUTION.md 第 1、2 條

功能

1. 新功能腳手架

當建立新功能時，自動生成 DDD 結構：

「新增 Order 領域」

生成：

│   └── DTOs/OrderDTO.py
└── Infrastructure/
    └── Persistence/Repositories/OrderRepository.py

2. 架構違規檢查

偵測並警告：

❌ Domain 層導入 Infrastructure
❌ 直接在 Domain 操作資料庫
❌ Application 層直接操作資料庫
❌ Repository 實作放在 Domain 層

3. 依賴方向驗證

✅ Presentation → Application → Domain
✅ Infrastructure → Domain (實作介面)
❌ Domain → Infrastructure
❌ Domain → Application

輸出格式

🏗️ DDD 架構檢查

✅ 依賴方向正確
✅ DAL 正確分離
⚠️ 警告：
  - src/Domain/Services/UserService.py:15
    導入了 Infrastructure 模組

建議：
  將資料庫操作移至 Repository

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
