dare-layered-design

dare-layered-design is a command for Claude Code from dewtech-technologies/dare-method. It costs 0 tokens per session (1,150 once invoked), scanned A, original, MIT.

A command set that checks and scaffolds a strict four-layer application structure: handlers receive requests, services hold business rules, repositories handle storage, and models represent domain data.

In plain words
What is it for?
Use it to audit layer rules, run architecture checks, or generate CRUD features with the expected separation. It applies across programming languages.
Why use it?
It prevents request handling, business logic, and database code from becoming mixed together, which makes projects harder to test and change.

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

dare-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 3d 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.

/dare-layered-design

Enforce arquitetura estrita de 4 camadas (Handlers, Services, Repositories, Models) em projetos DARE — independente de linguagem.

Como usar

/dare-layered-design                        # audita projeto atual
/dare-layered-design lint                   # roda checks AP-01 a AP-06
/dare-layered-design scaffold <recurso>     # gera CRUD com camadas corretas

As 4 camadas

Handler  →  Service  →  Repository  →  Model
(HTTP)      (negócio)   (I/O)         (domínio)

Handler

  • Recebe request, valida input, chama um Service, retorna response
  • Nunca acessa Repository direto, nunca instancia Service com new

Service

  • Implementa uma operação de negócio (RegisterUser, RefundPayment)
  • Orquestra Repositories
  • Nunca sabe sobre HTTP, nunca faz SQL inline

Repository

  • Abstrai persistência (DB, cache, API externa)
  • Retorna Model ou primitivo
  • Nunca retorna HTTP status, nunca lança exceção de domínio

Model

  • Entidade pura do domínio
  • Nunca importa Repository/Service/Handler

Métricas obrigatórias

ID Métrica
M-01 100% dos Services têm testes unitários (sem DB/HTTP real)
M-02 0% de chamadas Handler→Repository direto
M-03 100% dos Handlers usam injeção (sem new Service())
M-04 100% dos Repositories são agnósticos das camadas superiores

Tabela por linguagem

Service Services/ *.service.ts services/ app/services/ services/ services/
Repository Repositories/ *.repository.ts repositories/ app/repositories/ repositories/ repositories/
Model Models/ entities/ models/ app/models/ domain/ models/

Antipatterns

AP Antipattern Sinal

AP-02 Service com SQL inline db.query() em Service
AP-03 Repository lança exceção de domínio throw UserNotFound
AP-04 Model importa Service acoplamento invertido
AP-05 God Service (>20 métodos) UserService.everything()
AP-06 Fat Controller (>100 linhas) lógica em Handler

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.

dare-layered-design is a command published in the GitHub repository dewtech-technologies/dare-method (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,150 tokens. 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.
