architecture-patterns

architecture-patterns is a skill for Claude Code, Codex from sickn33/agentic-awesome-skills. It costs 34 tokens per session (427 once invoked), scanned A, original, MIT.

A guide to backend architecture patterns such as Clean Architecture, Hexagonal Architecture, and Domain-Driven Design. These patterns organise code and dependencies so systems are easier to change and test.

In plain words
What is it for?
It supports designing backend systems, defining module boundaries, refactoring monoliths, planning service splits, and making code easier to test.
Why use it?
It helps untangle tightly connected code and avoid choosing complex patterns without first considering the domain and constraints.

About the project

AAS Core is a local control plane for coding agents that lets them search a large catalogue of skills, choose a stack, validate it, and create a reproducible plan. It is used to assemble and review agent workflows through its CLI, local MCP server, catalogue, plugins, and Workbench. The catalogue add-ons provide the skills, plugins, bundles, and workflows that AAS Core helps agents select and validate.

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 4d 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.

What it actually says

Architecture Patterns

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

Use this skill when

  • Designing new backend systems from scratch
  • Refactoring monolithic applications for better maintainability
  • Establishing architecture standards for your team
  • Migrating from tightly coupled to loosely coupled architectures
  • Implementing domain-driven design principles
  • Creating testable and mockable codebases
  • Planning microservices decomposition

Do not use this skill when

  • You only need small, localized refactors
  • The system is primarily frontend with no backend architecture changes
  • You need implementation details without architectural design

Instructions

  1. Clarify domain boundaries, constraints, and scalability targets.
  2. Select an architecture pattern that fits the domain complexity.
  3. Define module boundaries, interfaces, and dependency rules.
  4. Provide migration steps and validation checks.
  5. For workflows that must survive failures (payments, order fulfillment, multi-step processes), use durable execution at the infrastructure layer — frameworks like DBOS persist workflow state, providing crash recovery without adding architectural complexity.

Refer to resources/implementation-playbook.md for detailed patterns, checklists, and templates.

Works well with: event-sourcing-architect, saga-orchestration, workflow-automation, dbos-*

Resources

  • resources/implementation-playbook.md for detailed patterns, checklists, and templates.

Limitations

  • Use this skill only when the task clearly matches the scope described above.
  • Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
  • Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Changes

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.
