py-clean-arch

py-clean-arch is a skill for Claude Code, Codex from CJHwong/py-clean-architecture-examples. It costs 113 tokens per session (1,816 once invoked), scanned A, original, no licence file.

A project-specific guide to applying Clean Architecture in Python. Clean Architecture separates business rules from interfaces and external tools, and this guide defines the project’s layers, folders, boundaries, and import rules.

In plain words
What is it for?
Use it when working on the referenced Python architecture, especially when adding layers, defining boundary interfaces, or checking import contracts.
Why use it?
It reduces uncertainty about where Python code belongs and which parts of the system may depend on one another.

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

py-clean-arch 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 10d ago.

The scan reads SKILL.md. This mod also ships 18 executable files (references/__init__.py, references/l1_entities/__init__.py, references/l1_entities/entity.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
