clean-architecture

clean-architecture is a skill for Claude Code, Codex from amadeus-dlc/amadeus. It costs 74 tokens per session (370 once invoked), scanned A, original, Apache-2.0.

A guide for projects that intentionally use Clean Architecture, a design that keeps business rules separate from delivery tools, databases, frameworks, and other technical details.

In plain words
What is it for?
Use it to place code in domain, use-case, adapter, or infrastructure layers and to review whether dependencies point inward correctly.
Why use it?
It helps prevent core business and use-case code from depending directly on infrastructure or framework mechanisms.

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

clean-architecture 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 9d 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

Clean Architecture

Use this skill only for projects that intentionally follow Clean Architecture. Keep policy inward and mechanisms outward.

Layer Rule

  • Domain: entities, value objects, aggregates, domain services, domain events, and invariants.

  • Use cases: application-specific orchestration, transaction boundaries, ports, authorization decisions that are application policy, and repository interface usage.

  • Interface adapters: controllers, presenters, gateways, repository implementations, RPC adapters, DTO mapping, and persistence mapping.

  • Infrastructure: cross-cutting mechanisms such as logging, configuration, metrics, DI wiring, clocks, IDs, and concrete driver setup.

Workflow

  1. Confirm the project actually uses Clean Architecture.

  2. Map the touched code to the four layers.

  3. Check dependency direction: outer layers may depend inward; inward layers must not know outer mechanisms.

  4. Move persistence, RPC, UI, and framework details out of domain and use-case code.

  5. Report the minimal relocation or interface extraction needed.

Reference

Read references/layer-responsibilities.md when placement is ambiguous.

Detailed Reference

For non-trivial implementation, review, or refactoring work, read references/details.md before giving final guidance. It contains the detailed rules, examples, smells, and migration notes that do not belong in the short invocation body.

Output

Provide a layer-by-layer finding list, dependency violations, and concrete file-placement recommendations.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
