ddd-architecture-awesome

ddd-architecture-awesome is a skill for Claude Code from full-stack-skills/ddd-skills. It costs 123 tokens per session (6,878 once invoked), scanned A, original, Apache-2.0.

Guidance for Domain-Driven Design, an approach that shapes software around the real business domain and its rules. It covers strategic boundaries, detailed building blocks, and architecture patterns.

In plain words
What is it for?
Use it to assess DDD applicability, choose an appropriate level of complexity, define boundaries, and understand core DDD concepts.
Why use it?
It helps decide whether DDD fits a project and prevents adopting complex patterns when the problem does not need them.

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

ddd-architecture-awesome 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 today.

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.

DDD Architecture Awesome

The entry point to the DDD Skills ecosystem. This skill provides everything needed to understand DDD, decide if it's right for your project, and chart your learning path — all in one place.

When to Use (and When NOT to)

✅ Use When ❌ Skip When
Complex business domain with many rules Simple CRUD, few business rules
Long-lived system (years of maintenance) Prototype, MVP, throwaway code
Team of 5+ developers Solo developer or small team (1-2)
Multiple entry points (API, CLI, events) Single entry point, simple API
Need to swap infrastructure (DB, broker) Fixed infrastructure, unlikely to change
High test coverage required Quick scripts, internal tools
Chinese enterprise Spring Boot + MyBatis stack Already using established architecture that works

Start simple. Evolve complexity only when needed. Most systems don't need full CQRS or Event Sourcing.

When to trigger this skill

ALWAYS use this skill when the user mentions:

  • "What is DDD", "Explain DDD", "DDD 是什么", "介绍一下 DDD"
  • "Domain-Driven Design", "领域驱动设计"
  • "DDD basics", "DDD fundamentals", "DDD 基础", "DDD 入门"
  • "Should I use DDD", "DDD 适用场景", "DDD 是否适合"
  • "DDD vs CRUD", "DDD vs traditional", "DDD 对比"
  • "DDD concepts", "DDD 概念"
  • "Strategic design DDD", "Tactical design DDD", "DDD 战略设计", "DDD 战术设计"
  • "When to apply DDD", "When DDD is appropriate"
  • Questions about DDD architecture types and their differences
  • New to DDD and seeking guidance on where to start

1. DDD Definition

Domain-Driven Design is a development methodology that brings complex business rules into domain models: first define business boundaries (Strategic Design), then encode rules into models (Tactical Design).

Key insight: DDD is not about technology — it's about aligning your code with how the business thinks.


2. DDD Applicability Decision Tree

Evaluate along these dimensions and provide a "Suitable / Cautious / Not Recommended" conclusion:

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.
