delphi-spring4d

delphi-spring4d is a skill for Claude Code from adrianosantostreina/delphi-dev. It costs 81 tokens per session (568 once invoked), scanned A, original, MIT.

A Delphi programming guide for Spring4D, a library that provides dependency injection and reusable collection types. Dependency injection lets an application provide the objects a service needs instead of creating them manually.

In plain words
What is it for?
Use it when registering and resolving services, configuring object lifetimes, or working with Spring4D lists, dictionaries, and enumerable collections.
Why use it?
It helps when manually wiring services and managing typed lists or dictionaries becomes difficult.

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

delphi-spring4d 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 6d 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.

What it actually says

Delphi Spring4D

Idioma de saída

Detecte o idioma da primeira mensagem. Padrão: pt-BR. Respeite overrides explícitos.

Quando usar Spring4D

  • DI Container — quando o grafo de dependências cresce e o constructor injection manual fica trabalhoso de montar (ver rules/architecture.md para a base de DI).
  • CollectionsIList<T>, IDictionary<TK,TV>, IEnumerable<T> com semântica de interface (ARC) em vez de TObjectList<T> manual.

DI Container — registro e resolução

uses
  Spring.Container;

// Registro (na inicialização da aplicação)
GlobalContainer.RegisterType<IClienteRepository, TClienteFDRepository>;
GlobalContainer.RegisterType<IClienteService, TClienteService>;
GlobalContainer.Build;

// Resolução
var LService: IClienteService;
LService := GlobalContainer.Resolve<IClienteService>;

O container resolve a cadeia: ao pedir IClienteService, injeta automaticamente o IClienteRepository no construtor de TClienteService.

Tempo de vida (lifetime)

GlobalContainer.RegisterType<IClienteService, TClienteService>
  .AsSingleton;          // uma instância para toda a aplicação
// .AsTransient (padrão)  // nova instância a cada Resolve
// .PerResolve            // uma instância por grafo de resolução

Collections

uses
  Spring.Collections;

var
  LClientes: IList<TCliente>;
begin
  LClientes := TCollections.CreateObjectList<TCliente>(True); // owns objects
  LClientes.Add(TCliente.Create);
  // Sem try/finally manual — ARC libera a lista e seus objetos
end;

Regras

  • Registrar interfaces → implementações, nunca classes concretas diretamente
  • Preferir AsSingleton para services/repositories sem estado mutável
  • IList<T> / IDictionary<T> (interface) em vez de TList<T> quando quer ARC
  • O container não substitui o rules/architecture.md — é a ferramenta que automatiza o constructor injection que aquele documento exige

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.
