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.

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 | $0.00050 | $0.04549 |
| Opus 5 | $0.00025 | $0.02275 |
| Sonnet 5 | $0.00010 | $0.00910 |
| Haiku 4.5 | $0.00005 | $0.00455 |
Grade A, and why
validate-documentation 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 2d 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 — 415 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: Validação de Documentação
Esta skill analisa e valida documentação existente contra padrões de qualidade.
Quando Usar
Claude deve invocar esta skill automaticamente quando:
- Usuário pedir para validar/verificar documentação
- Usuário mencionar "review", "audit" ou "checar" documentos
- Antes de finalizar criação de documentação (auto-validação)
- Usuário pedir status de qualidade da documentação
Critérios de Validação
1. Validação Estrutural (Documentos UC)
Seções Obrigatórias:
- [ ] Informações Gerais (tabela com ID, Nome, Domínio)
- [ ] Descrição (mínimo 2 parágrafos)
- [ ] Atores (tabela com tipo e descrição)
- [ ] Pré-condições (lista numerada)
- [ ] Pós-condições (sucesso e falha)
- [ ] Fluxo Principal (diagrama + tabela)
- [ ] Fluxos Alternativos (ao menos 1)
- [ ] Exceções (tabela com códigos)
- [ ] Regras de Negócio (tabela com IDs)
- [ ] Casos de Teste (tabela com cenários)
- [ ] Dependências (relacionamentos)
Padrões de ID:
UC-[A-Z]{2,4}-\d{3} # UC-CAD-001, UC-AUTH-001
RN\d{2} # RN01, RN02
CT\d{2} # CT01, CT02
E\d{3} # E001, E002
FA\d # FA1, FA2
RNF\d{2} # RNF01, RNF02
2. Validação de Conteúdo
Descrição:
- Mínimo 100 caracteres
- Deve explicar O QUE e POR QUE
Atores:
- Pelo menos 1 ator primário
- Tipo deve ser: Primário, Secundário ou Sistema
- Descrição deve ser clara
Fluxo Principal:
- Diagrama Mermaid deve ser válido
- Passos devem ser numerados sequencialmente
- Cada passo deve ter descrição clara
Regras de Negócio:
- Cada regra deve ser acionável
- Regras complexas devem ter detalhamento
Casos de Teste:
- Mínimo 5 casos por UC
- Deve cobrir: sucesso, erro, edge cases
- Cada caso deve ter entrada e saída esperada
3. Validação de Consistência
Cross-references:
- Dependências devem referenciar UCs existentes
- Links internos devem ser válidos
- IDs não devem ser duplicados
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

validate-documentation is a skill published in the GitHub repository JotJunior/cstk (22 stars, last pushed 3d ago), licensed MIT. It adds 50 tokens to every session and 4,549 once invoked, about $0.0003 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.
