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-firedac 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 9d 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 FireDAC

Idioma de saída

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

Regras fundamentais FireDAC

  1. Sempre registrar drivers explicitamente — ver knowledge/core/firedac-registro-drivers.md
  2. TFDQuery: criar, usar, liberar dentro do método — não manter aberto
  3. Transações explícitas para operações de escrita múltipla
  4. Parâmetros tipadosParamByName('id').AsInteger, nunca AsString para números

Padrão de uso de TFDQuery

procedure TClienteRepository.SalvarCliente(ACliente: ICliente);
var
  LQuery: TFDQuery;
begin
  LQuery := TFDQuery.Create(nil);
  try
    LQuery.Connection := FConnection;
    LQuery.SQL.Text :=
      'INSERT INTO clientes (nome, ativo) VALUES (:nome, :ativo)';
    LQuery.ParamByName('nome').AsString := ACliente.Nome;
    LQuery.ParamByName('ativo').AsBoolean := ACliente.Ativo;
    LQuery.ExecSQL;
  finally
    LQuery.Free;
  end;
end;

Memory leak comum

TFDQuery criado como campo da classe e nunca liberado no destructor. TFDQuery criado com Owner = Self em método: liberado quando o form fecha, não quando o método termina.

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.
