clean-architecture

clean-architecture is a skill for Claude Code, Codex from pproenca/dot-skills. It costs 64 tokens per session (1,608 once invoked), scanned A, original, MIT.

A set of guidelines for structuring software into separate layers, with business rules kept independent from databases, web frameworks, and other outside details.

In plain words
What is it for?
Use it when designing systems, defining boundaries between layers, reviewing architecture, or reorganizing an existing application.
Why use it?
It helps prevent tightly coupled code that is difficult to test, change, or maintain. It gives developers a way to review dependencies and refactor tangled applications.

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 5d 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.

Clean Architecture Best Practices

Comprehensive guide to Clean Architecture principles for designing maintainable, testable software systems. Based on Robert C. Martin's "Clean Architecture: A Craftsman's Guide to Software Structure and Design." Contains 42 rules across 8 categories, prioritized by architectural impact.

When to Apply

Reference these guidelines when:

  • Designing new software systems or modules
  • Structuring dependencies between layers
  • Defining boundaries between business logic and infrastructure
  • Reviewing code for architectural violations
  • Refactoring coupled systems toward cleaner structure

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.
