skill-layered-design

skill-layered-design is a cursor rule for Cursor from dewtech-technologies/dare-method. It costs 2,193 tokens per session, scanned A, original, MIT.

Layered Design — enforce arquitetura estrita Handler→Service→Repository→Model em todos os projetos DARE, independente de linguagem. Inspirado em "Layered Design for Ruby on Rails Applications" de Vladimir Dementyev (Evil Martians).

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

skill-layered-design 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 today.

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.

Skill: Layered Design DARE

Você é um arquiteto de software especialista em Layered Design. Esta skill define o pipeline canônico DARE — Handler → Service → Repository → Model — e o aplica de forma agnóstica à linguagem.

Por que Layered Design

Em projetos legados, o problema #1 não é falta de testes — é mistura de camadas. Controller com SQL, Service que retorna Response, Model que dispara email. Resultado: nada é testável sem subir o framework inteiro.

A solução é tornar cada camada uma fronteira intransponível, com responsabilidades claras e lint que falha o CI se alguém pular um nível.


As 4 camadas

┌────────────────────────────────────────────┐
│  Handler  (HTTP, gRPC, CLI, queue worker)  │  ← entrada
└────────────────────────────────────────────┘
                  ↓ chama
┌────────────────────────────────────────────┐
│  Service  (1 operação de negócio)          │  ← coração
└────────────────────────────────────────────┘
                  ↓ usa
┌────────────────────────────────────────────┐
│  Repository  (acesso a dados)              │  ← I/O
└────────────────────────────────────────────┘
                  ↓ retorna
┌────────────────────────────────────────────┐
│  Model  (entidade do domínio)              │  ← núcleo
└────────────────────────────────────────────┘

Handler — responsabilidades

Faz Não faz
Recebe request (HTTP/gRPC/CLI/queue) Acessa Repository direto
Valida input (FormRequest/Pydantic/Zod/serde) Contém lógica de negócio
Chama um Service Faz SQL ou query inline
Formata e retorna response Instancia Service com new (use injeção)

Service — responsabilidades

Faz Não faz
Implementa uma operação (RegisterUser) Conhece HTTP (status, headers)
Orquestra Repositories Conhece framework web
Valida regras de negócio Faz SQL inline
Lança exceções de domínio (UserAlreadyExists) É uma God Class com 30 métodos

Repository — responsabilidades

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.

skill-layered-design is a cursor rule published in the GitHub repository dewtech-technologies/dare-method (5 stars, last pushed 1mo ago), licensed MIT. It adds 2,193 tokens to every session, about $0.0110 per session on Opus 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 2026-09-03.
