architecture-patterns

architecture-patterns is a skill for Claude Code, Codex from RudyCity/superagent. It costs 65 tokens per session (1,630 once invoked), scanned A, a copy of architecture-patterns, MIT.

A set of backend design patterns for organizing business rules, application actions, and outside systems such as databases or web frameworks. It covers Clean Architecture, Hexagonal Architecture, and Domain-Driven Design.

In plain words
What is it for?
Use it when designing a backend service, splitting a monolith into clearer business areas, defining service boundaries, or creating aggregates, value objects, and domain events.
Why use it?
It helps prevent business logic from becoming tangled with database or web code. This makes dependencies clearer and allows use cases to be tested without running a database.

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-patterns 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 7d 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.

Architecture Patterns

Master proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design to build maintainable, testable, and scalable systems.

Given: a service boundary or module to architect. Produces: layered structure with clear dependency rules, interface definitions, and test boundaries.

When to Use This Skill

  • Designing new backend services or microservices from scratch
  • Refactoring monolithic applications where business logic is entangled with ORM models or HTTP concerns
  • Establishing bounded contexts before splitting a system into services
  • Debugging dependency cycles where infrastructure code bleeds into the domain layer
  • Creating testable codebases where use-case tests do not require a running database
  • Implementing domain-driven design tactical patterns (aggregates, value objects, domain events)

Core Concepts

1. Clean Architecture (Uncle Bob)

Layers (dependency flows inward):

  • Entities: Core business models, no framework imports
  • Use Cases: Application business rules, orchestrate entities
  • Interface Adapters: Controllers, presenters, gateways — translate between use cases and external formats
  • Frameworks & Drivers: UI, database, external services — all at the outermost ring

Key Principles:

  • Dependencies point inward only; inner layers know nothing about outer layers
  • Business logic is independent of frameworks, databases, and delivery mechanisms
  • Every layer boundary is crossed via an abstract interface
  • Testable without UI, database, or external services

2. Hexagonal Architecture (Ports and Adapters)

Components:

  • Domain Core: Business logic lives here, framework-free
  • Ports: Abstract interfaces that define how the core interacts with the outside world (driving and driven)
  • Adapters: Concrete implementations of ports (PostgreSQL adapter, Stripe adapter, REST adapter)

Benefits:

  • Swap implementations without touching the core (e.g., replace PostgreSQL with DynamoDB)
  • Use in-memory adapters in tests — no Docker required
  • Technology decisions deferred to the edges

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.
