rn-architecture

rn-architecture is a skill for Claude Code, Codex from cmaranho/rn-agent-skills. It costs 55 tokens per session (1,164 once invoked), scanned A, original, MIT.

A set of rules for structuring React Native apps with Clean Architecture, a way to keep user-interface code, business decisions, and data access in separate layers.

In plain words
What is it for?
Use it when creating or refactoring features, choosing where logic belongs, defining repositories and use cases, or connecting data to screens through hooks.
Why use it?
It prevents business logic and API calls from being tangled into screens. This makes data flow easier to follow and each layer easier to test.

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

rn-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 2mo 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.

React Native — Arquitetura

Objetivo

Aplicar uma arquitetura em camadas, testável e escalável para features React Native, com fluxo de dados previsível da fonte de dados à UI.

Quando utilizar

  • Criar um módulo ou feature novo.
  • Decidir onde colocar lógica (UI, estado, caso de uso, dados).
  • Refatorar código com regra de negócio na UI ou chamada de API no componente.

Conhecimentos necessários

  • Clean Architecture e a regra de dependência (dependências apontam para dentro).
  • Padrões Repository, Use Case e Mapper/Helper.
  • Injeção de dependência simples (construtor/factory).
  • Diferença entre transformação de shape (mapper) e cálculo/estado (helper).

Fluxo de execução

  1. Modele o contrato de dados: DTOs de entrada/saída e models de domínio.
  2. Implemente o repositório: encapsula IO/HTTP e retorna resultado tipado (sucesso/erro), sem lançar exceção crua.
  3. Implemente o caso de uso: orquestra repositório + mappers/helpers e retorna estado tipado ({ type: 'SUCCESS' | 'ERROR' }).
  4. Exponha estado via store/hook que consome o caso de uso (nunca o repositório direto).
  5. Conecte a UI por um hook de tela (use-*-screen); mantenha a tela fina.
  6. Escreva testes por camada.
Tela → hook de tela → estado → caso de uso → repositório → cliente HTTP
                                   ↘ mappers / helpers ↗

Estrutura de pastas

Reflita as camadas na organização física. Os nomes são convenção — adapte ao seu projeto, preservando os papéis. Separe código de domínio (modules/) de código compartilhado (common/).

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.

rn-architecture is a skill published in the GitHub repository cmaranho/rn-agent-skills (2 stars, last pushed 4mo ago), licensed MIT. It adds 55 tokens to every session and 1,164 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
