implement

implement is a skill for Claude Code, Codex from idosreisjunior/sdd-claude-kit. It costs 104 tokens per session (1,526 once invoked), scanned A, original, Apache-2.0.

Uma etapa controlada para executar uma tarefa de desenvolvimento já aprovada. Ela verifica a aprovação, escolhe uma tarefa com dependências concluídas e atualiza o plano e o estado da mudança.

In plain words
What is it for?
Serve para executar uma tarefa por vez em um processo baseado em especificações, atualizar tasks.md e a matriz de rastreabilidade, e interromper quando falta uma decisão necessária.
Why use it?
Evita alterar código sem autorização válida ou fora da ordem planejada. Também mantém o plano e o registro de quais requisitos estão ligados a cada tarefa atualizados.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

implement 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.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/sdd-kit:implement — implementar uma tarefa

Executa uma tarefa aprovada e mantém verdadeiros o plano e a rastreabilidade. É a primeira skill do framework com efeito colateral irreversível — por isso os portões vêm antes de qualquer escrita.

Por que esta skill NÃO é autoinvocável

disable-model-invocation: true porque implement altera código e depende de uma aprovação humana válida (Art. 3). Invocá-la sozinha seria implementar sem o ato que a autoriza. Ver ADR-008.

Modo de governança

Leia workflow.mode de .specs/config.yaml antes de agir.

Modo Comportamento desta skill
advisory Informa a tarefa selecionada e os portões; nunca bloqueia — mas respeita require_approval
guided (padrão) Pede confirmação da tarefa selecionada antes de executar
strict Ainda não implementado na Fase 1. Informe isso ao usuário e opere como guided

Nunca finja um bloqueio que não existe. Dizer que o modo strict impediu algo, quando ele não está implementado, é pior que não ter o modo — cria confiança em uma proteção ausente.

Arquivos que esta skill lê

Quando O quê
Sempre .specs/config.yaml — modo, require_approval e require_tests
Sempre <dir-da-mudança>/status.yaml — estado, approval e contadores
Sempre <dir-da-mudança>/tasks.md — o plano e as dependências
Sempre <dir-da-mudança>/spec.md — para recalcular o hash da revisão aprovada
Se existir <dir-da-mudança>/design.md e traceability.yaml — o design da tarefa e a matriz

Escreve apenas nos arquivos declarados na tarefa selecionada. Sair disso exige justificativa explícita (Art. 4 e Art. 5).


Procedimento

Portões — todos ANTES da primeira escrita

  1. Aprovação exigida. Com require_approval: true e approval: null, recuse: informe que a configuração exige aprovação e não altere nenhum arquivo de código (SCN-SWC-012). Sugira /sdd-kit:approve.

  2. Aprovação vencida. Recalcule o SHA-256 de spec.md e compare com approval.revision. Se divergir, a spec mudou depois da aprovação: reporte a aprovação como vencida e recuse avançar. Não regrida o estado por conta própria — reescrever o histórico sem decisão humana é o que o ADR-013 proíbe (SCN-SWC-020).

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.

implement is a skill published in the GitHub repository idosreisjunior/sdd-claude-kit (11 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 104 tokens to every session and 1,526 once invoked, about $0.0005 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.
