A command that proposes and generates DUnitX unit tests for Delphi projects. Unit tests are small automated checks for individual pieces of code, and DUnitX is a Delphi testing framework.

Use it to review a Delphi project, propose test cases, generate test files and a DUnitX runner, and continue adding tests after new implementations are written.

It helps identify important logic to test and creates a repeatable test suite after the developer approves the proposal. It focuses on services, repositories, and utilities rather than visual forms or classes without their own logic.

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.

npx agentmods add commands/adrianosantostreina/delphi-dev/tdd

Clone the repo

git clone --depth 1 https://github.com/adrianosantostreina/delphi-dev

Or install delphi-dev, the plugin that ships this one along with the rest of its 15 skills, 10 commands, 4 agents.

Per session 16 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 412 The whole file, excluding the scripts and references it only reads on demand.

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.

Model	Per session	Once invoked
Fable 5	$0.00016	$0.00412
Opus 5	$0.00008	$0.00206
Sonnet 5	$0.00003	$0.00082
Haiku 4.5	$0.00002	$0.00041

Measured 5d ago against content hash 00f226026b98, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

tdd 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 5d 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

Inicie a criacao de testes unitarios DUnitX para o projeto Delphi atual.

Idioma: Detecte o idioma do usuario e responda sempre nesse idioma. Padrao: pt-BR. Idiomas suportados: pt-BR, en-US. Honre overrides: "respond in English" / "responda em portugues". Identificadores Delphi (nomes de teste, fields, classes) seguem a convencao do projeto e nao sao traduzidos — apenas a prosa, propostas e notificacoes.

Este comando opera em Fase 1 (setup inicial):

Analise do Projeto — Ler todas as units do projeto e identificar o que pode ser testado. Prioridade: servicos de negocio, repositorios, utilitarios com logica. Ignorar: Forms, DataModules, classes sem logica propria.
Proposta — Apresentar a suite de testes proposta com a lista de casos por classe:
```
[TClienteService] — N casos
  ✓ Test_Salvar_ClienteValido_Salva
  ✓ Test_Salvar_ClienteSemNome_LancaExcecao
  ...
```
Aguardar aprovacao do usuario antes de gerar.
Geracao — Produzir todos os arquivos Teste[NomeDaClasse].pas e o projeto TestRunner.dpr com o runner DUnitX.

Fase 2 (continua automaticamente): Apos cada nova implementacao via /write, o agente delphi-tester cria os testes da nova classe automaticamente e notifica o usuario com a lista dos casos criados.

Use o agente delphi-tester para executar a analise e geracao. Carregue a skill delphi-tests e os padroes em references/dunitx-patterns.md.

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.

tdd is a command published in the GitHub repository adrianosantostreina/delphi-dev (79 stars, last pushed 4d ago), licensed MIT. It adds 16 tokens to every session and 412 once invoked, about $0.0001 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 2026-08-30.
