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 | $0.00114 | $0.01470 |
| Opus 5 | $0.00057 | $0.00735 |
| Sonnet 5 | $0.00023 | $0.00294 |
| Haiku 4.5 | $0.00011 | $0.00147 |
Grade A, and why
design 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 10d 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/sdd-kit:design — desenhar a solução
Transforma uma spec clarificada em um design técnico revisável, com as decisões arquiteturais registradas como ADRs.
disable-model-invocation: false é deliberado: design produz um documento revisável e não age sobre nenhuma decisão irreversível. Ver ADR-008.
A regra que governa esta skill
O design descreve o como; a spec descreve o o quê e o porquê. Se você está escrevendo requisitos aqui, está no documento errado — volte para /sdd-kit:spec. E decisão arquitetural relevante vira um ADR, não um parágrafo perdido dentro do design.md: uma decisão sem rastro próprio é indistinguível de uma suposição (Art. 5), e é o Artigo 8 que exige interromper e registrar diante de uma escolha arquitetural.
Modo de governança
Leia workflow.mode de .specs/config.yaml antes de agir.
| Modo | Comportamento desta skill |
|---|---|
advisory |
Informa o design proposto e as decisões; nunca bloqueia nem exige confirmação |
guided (padrão) |
Recusa desenhar fora de CLARIFIED e pede confirmação antes de promover a DESIGNED |
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 — idioma e modo |
| Sempre | <dir-da-mudança>/spec.md — os requisitos e os cenários a atender |
| Sempre | <dir-da-mudança>/status.yaml — estado atual, para avaliar a transição |
| Se existir | .specs/project/architecture.md — limites de módulo e a estrutura a respeitar |
| Se existir | .specs/project/context.md — o contexto técnico do projeto |
Não leia as specs de outras mudanças (NFR-SWC-002, Art. 7). O design é sobre esta mudança e o projeto, não sobre o que outras estão fazendo.
Procedimento
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.

design is a skill published in the GitHub repository idosreisjunior/sdd-claude-kit (11 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 114 tokens to every session and 1,470 once invoked, about $0.0006 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.
