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 5.1 | $0.00043 | $0.00771 |
| Opus 5.5 | $0.00017 | $0.00308 |
| Sonnet 5.5 | $0.00009 | $0.00154 |
| Haiku 4.5 | $0.00004 | $0.00077 |
Grade A, and why
dev-defuddle 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 27d 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.
Defuddle — Web Content Extraction
Defuddle extrai o conteúdo principal de páginas web em Markdown limpo, removendo navegação, anúncios, sidebars e qualquer elemento que não seja o conteúdo em si.
Verificar disponibilidade antes de usar
Sempre verificar antes de chamar defuddle:
# Verificar se defuddle está disponível
which defuddle 2>/dev/null || npx --yes @kepano/defuddle-cli --version 2>/dev/null
- Se disponível globalmente → usar
defuddle {url} - Se não disponível → usar
npx @kepano/defuddle-cli {url}(instala temporariamente) - Se npx falhar (sem rede/permissão) → usar fallback
WebFetchabaixo
Instalação (por projeto, se necessário)
npm install -g @kepano/defuddle-cli
# ou via npx sem instalação
npx @kepano/defuddle-cli {url}
Uso básico
# Extrair conteúdo de uma URL
defuddle https://docs.react.dev/learn/state-a-components-memory
# Salvar em arquivo para referência
defuddle https://example.com/article > docs/research/article-title.md
# Via npx (sem instalação prévia)
npx @kepano/defuddle-cli https://example.com/article
Fallback obrigatório — quando defuddle não está disponível
WebFetch(url, "Extract the main technical content only, ignoring navigation, ads, sidebars, headers and footers. Return as clean markdown with headings, code blocks and lists preserved.")
Usar o fallback sempre que:
defuddlenão encontrado Enpxfalhar- Página requer autenticação (defuddle não consegue)
- Timeout no CLI
Quando usar
- Research de documentação técnica (comparar bibliotecas, ler specs)
- Capturar artigos técnicos para referência durante análise
- Extrair conteúdo de páginas de concorrentes para análise de produto
- Documentação de APIs externas para o Architect tomar decisões
- Research de UX patterns e referências visuais
Onde salvar conteúdo extraído
docs/research/ → pesquisas técnicas gerais
docs/research/ux/ → referências de UX e design
docs/research/market/ → análise de concorrentes/mercado
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.
