Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 5.1 | $0.00104 | $0.01526 |
| Opus 5.5 | $0.00042 | $0.00610 |
| Sonnet 5.5 | $0.00021 | $0.00305 |
| Haiku 4.5 | $0.00010 | $0.00153 |
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 2mo 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
-
Aprovação exigida. Com
require_approval: trueeapproval: null, recuse: informe que a configuração exige aprovação e não altere nenhum arquivo de código (SCN-SWC-012). Sugira/sdd-kit:approve. -
Aprovação vencida. Recalcule o SHA-256 de
spec.mde compare comapproval.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 2mo ago), licensed Apache-2.0. It adds 104 tokens to every session and 1,526 once invoked, about $0.0004 per session on Opus 5.5. 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.
